# API 契约与项目生成
|

|

当前生成目录和启动扩展采用新布局，见 [项目维护指南](PROJECT.md)。`@app(defaultResponse: Name)` 在入口选择 App 默认响应。`@body(mode: raw|multipart)` 和 `@produces` 支持自动 Handler，手写 Handler 仅为显式选择的扩展。

首次接入请先看 [README](README.md)：包含固定远程版本安装、可运行项目、完整 `.api` 示例和已有服务接入步骤。本页用于查阅语法与生成规则；下方带 `--framework-dir` 的命令用于框架源码开发。
|
||||
|
||||
本阶段目标：从 `.api` 定义生成可运行的 Go 项目；定义、绑定、校验与 OpenAPI 保持一致；重复生成不覆盖业务实现；业务代码继续独立于网络层。实现入口是 `cmd/go-omni/apigen`，运行时契约编译器是 `contract`。

业务错误、具名鉴权、多行文档及下述开发命令从 CLI `v0.7.0-preview.1` 提供。公共响应模板从 `v0.8.0-preview` 提供，CLI 与业务项目中的框架依赖需一起升级。
|
||||
|
||||
## 业务错误：声明、代码和文档共用一份定义
|
||||
|
||||
**错误目录也可以只在 Go 中维护。** 从 `v0.11.1-preview` 起，生成路由没有声明错误列表时，继承 `omni.WithErrors(catalog)` 注册的 App 目录；`.api` 继续定义接口和返回格式，无需重复登记错误。全局中间件提前返回同样适用。显式引用 `.api` 错误时才使用路由独立目录，规则见 [目录继承](errors/README.md)。CLI 不执行运行时 Go 配置，因此静态文档不会自动枚举只在 Go 中定义的具体错误。
|
||||
|
||||
从 `v0.10.0-preview` 起，推荐用 `errorCatalog` 同时定义逻辑标识、对外业务码、提示和 HTTP 状态：
|
||||
|
||||
```text
|
||||
errorCatalog CommonErrors (
|
||||
defaultStatus: 200
|
||||
errors: {
|
||||
"UsernameInvalid": {"key": "USERNAME_INVALID", "code": 400002, "message": "用户名格式不正确"},
|
||||
"PasswordInvalid": {"key": "PASSWORD_INVALID", "code": 400002, "message": "密码格式不正确"},
|
||||
"Forbidden": {"key": "FORBIDDEN", "status": 403, "code": 403001, "message": "没有权限"}
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
对象键是生成函数名；`key` 是唯一逻辑标识，允许项目自己的命名；`code` 是对外业务码，可以重复。数字码需搭配 `codeType: int32` 或 `int64` 的公共响应；字符串码搭配 `string`。目录不规定返回体字段。
|
||||
|
||||
省略 `defaultStatus` 时为 400；设为 200 时，只作用于目录里未单独写 `status` 的条目。生成路由自动绑定它实际声明的错误目录，在 App 中间件之前生效。业务只调用 `apierrors.UsernameInvalid()`；无需再维护 `codes` / `messages`，也无需修改 main。手写路由可复用生成的 `apierrors.Catalog()`。
|
||||
|
||||
同一 HTTP 200 下，OpenAPI 用 `anyOf` 保留成功 DTO 和错误体，日志与指标仍识别业务失败。完整语法、路由作用域与手写项目配置见 [统一错误目录](errors/README.md)，可运行契约见 [errors.api](examples/contracts/errors.api)。
|
||||
|
||||
从 `v0.11.0-preview` 起，目录条目支持 `params` 有序列表与 `{name}` 提示模板：
|
||||
|
||||
```json
|
||||
"TextTooLong": {
|
||||
"key": "TEXT_TOO_LONG", "code": 400002,
|
||||
"message": "{label}不能超过{max}个字符",
|
||||
"params": [
|
||||
{"name": "label", "type": "string", "example": "企业名称"},
|
||||
{"name": "max", "type": "int", "example": 100}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
生成 `apierrors.TextTooLong(label string, max int)`，返回时 Message 已填好；固定提示保持无参数函数。声明顺序决定参数顺序。模板校验、运行时缺参/类型错误、转义及非 HTTP 使用规则见 [提示模板参数](errors/README.md)。OpenAPI 的错误目录保留参数定义，响应示例使用具体文案。

|
||||
- 动态 JSON 字段 `any` / `interface{}`，包含切片和 map；外围契约仍严格。
|
||||
- `scalar Name (...)` 显式引用项目类型，声明 JSON 输入/输出类型及文本绑定；支持已有 JSON/Text 转换方法。
|
||||
- `@body (mode: json/raw/multipart; maxBytes: ...)`：按路由限制请求体。
|
||||
- `@binding custom` 生成保留的绑定 hook；`@handlerMode manual` 生成保留的整个 Handler，仅用于自定义协议。raw/multipart 默认生成自动 Handler，将受限流交给 Logic。
|
||||
- `@produces "text/plain"` 等声明无 DTO 成功输出；自动模式的 Logic 返回 `*httpx.Stream`，Handler 负责流式发送和关闭。默认状态 200。manual 模式保留项目自己的输出实现。
|
||||
- 自动 multipart Handler 检查未读部分和结束边界；损坏/截断默认返回 400，超限为 413。公共状态、码和文案仍可用项目错误目录配置，见 [流式接入与错误处理](PROJECT.md#自动上传回调与下载)。
|
||||
|
||||
迁移扩展起始于 v0.9.0，原有手写扩展说明见 [迁移扩展指南](MIGRATION.md)。当前根目录入口和自动流式 Handler 要求 CLI 与框架依赖一起使用 v0.13.0-preview；版本说明和新目录维护规则见 [项目指南](PROJECT.md)。不兼容全部 goctl 语法。

|
||||
|
||||
业务需要区分“没传”和“传了零值”时使用 `*T` 加 optional。指针允许 JSON null；非指针拒绝 null；`binding:"required"` 拒绝指针 null。缺失与 null 都会得到 nil，本版没有三态 Nullable 类型。响应端的 `optional` 不等于 Go 编码器的 `omitempty`；需要省略零值时显式使用 `omitempty`。

- 生成器最低框架版本更新到 v0.13.0-preview；manifest v2 和业务文件保持。v0.12 项目需要显式升级其 svc 扩展，main/Handler 由重新生成更新。
|
||||
- 增加故障退出、排空/清理顺序、初始化期间通知、子进程退出码、健康格式、损坏编码器、端点禁用/改名/冲突的回归验收。
|
||||
|
||||
## v0.12.0-preview（2026-09-24）
|
||||
|
||||
- 生成项目统一采用根目录 main.go 和 config/svc/logic/handler；new 与 api new 共用受管理生成器，manifest v2 不兼容旧目录。
|
||||
- main 和 HTTP 装配持续生成；svc 提供 AppOptions、GlobalMiddleware、OnClose 和幂等 Close，初始化失败回收资源，正常退出先排空 HTTP 再关闭项目依赖及日志。
|
||||
- 入口 @app(defaultResponse: Name) 自动接入 App 默认响应；生成路由、全局中间件及 404/405 共用策略，Go 错误目录保持单处注册。
|
||||
- raw/multipart 输入和 @produces 流式输出支持自动 Handler，Logic 接收受限请求流/返回可关闭内容流，保留显式手写扩展。
|
||||
- 新增真实生成项目生命周期、流式输入输出、文件保留和入口漂移检查，提供可运行 managedService 示例与 PROJECT.md。
|
||||
- multipart 流式读取保留解析错误，检查未消费部分与最终边界；损坏请求默认 400，超限保持 413，错误目录可定制公开响应。配置校验与实际 App 响应编码器/错误目录装配使用同一规则，冲突在构造前报错。
|
||||
- manifest 保存契约快照；生成/预览/检查提供接口类型、嵌套 DTO、scalar、body/流式模式变更提示，定位受影响的 Logic。轻量源码检查识别签名、语法和重复方法问题；--check 在重新生成后仍拒绝明确的业务签名错误，保留所有手写文件，类型别名/build tags 等不确定情况提示人工复查。
|
||||
|
||||
|
||||
## v0.11.1-preview
|
||||
|
||||
- 修复生成路由用空错误目录遮蔽 App 目录的问题；空 WithErrors 完全透传，避免 Context 与 Encoder 二次解析时丢失状态、业务码和中文提示。
|
||||
- 未声明错误列表的路由继承 App，支持错误只在 Go 中维护；显式路由目录保持独立，响应格式、RawJSON、body limit 和全局中间件提前返回保持正确策略。
|
||||
- 兼容已有 v0.11.0 生成代码；CLI 不再为空列表绑定目录。补充纯 Go 错误目录的实际生成消费者与回归验收。
|
||||
|
||||
## v0.11.0-preview
|
||||
|
||||
- 错误目录增加有序 params 和命名提示模板，生成带类型的错误函数；固定提示保持兼容，业务不再自行拼接文案。
|
||||
- 新增 WithParams、参数校验与共用解析器；复制请求参数、保留错误链，重复解析和缓冲链路保留填充结果。非法调用转系统兜底，访问日志提供不含参数值的诊断。
|
||||
- OpenAPI 错误目录同步参数类型/示例，响应示例由运行时解析器生成；JSON/YAML 配置同样支持模板。
|
||||
- 本地/共享幂等重放保存已解析公开错误快照，不保存原始参数或 cause；Redis Lua 重写记录不损失 int64 业务码精度。
|
||||
- 模板编译拒绝未声明/未使用参数、非法类型及示例；模板错误不能再维护同标识的旧 messages 映射。
|
||||
- CLI 新生成代码最低要求 v0.11.0-preview；已生成的固定错误函数和 v0.10.0 调用继续支持。
|
||||
|
||||
## v0.10.0-preview
|
||||
|
||||
- 新增 App/路由独立错误目录：`omni.WithErrors`、`errors.Catalog`、`ByCode` 与不可变 Registry，业务只选逻辑标识；对外码和提示由项目配置。
|
||||
- 默认 HTTP 状态与逐项覆盖均可配置，包括 HTTP 200 的业务失败；错误模板、RawJSON、日志、业务失败指标、链路、标准中间件桥接和幂等重放保留失败语义。
|
||||
- `.api errorCatalog` 同源生成 Catalog、独立错误函数、路由目录和 OpenAPI；允许重复对外码、不同路由不同码类型、公共契约导入。旧 error 声明也允许 HTTP 200。
|
||||
- 同一 200 的成功/错误响应使用 anyOf 保留两种 schema，错误示例保持各自提示；自定义 Encoder 和直接输出继续支持。
|
||||
- 目录校验类型、范围、状态和冲突；JSON 配置拒绝重复键，整数保留 int64 精度；未知标识使用系统兜底，默认公开响应不暴露 cause。
|
||||
- 新生成代码最低要求 v0.10.0-preview；原有构造函数、Codes/Messages 与旧生成代码继续可用。Catalog 为生成错误包保留函数名。
|
||||
|
||||
|
||||
## v0.9.1-preview
|
||||
|
||||
- 新增标准 `database.OpenConnector` 和独立 `PoolConfig`；与 DSN 入口共享池参数、限时启动 Ping、失败清理、Health、事务，不注册全局驱动配置。
|
||||
- 新增 `omni.WithHTTPConfig` / `Config.HTTP`：读头、读请求、写响应、空闲超时和头大小，贯通代码、JSON/YAML、环境变量、Run/Serve 与 NewServer；nethttp 支持 Go-only ErrorLog。
|
||||
- 保持已有默认行为；负值和实验 http2 不支持的超时项在监听前报错；记录各网络层的具体语义。
|
||||
- 增加真实 MySQL TLS/驱动日志隔离、连接池归属/取消/事务、nethttp/native 慢连接与写背压验收，以及无本地 replace 的远程消费者脚本。
|
||||
- 兼容 v0.9.0-preview 生成代码；不修改业务项目的数据库策略或生成代码最低版本。
|
||||
|
||||
|
||||
## v0.9.0-preview
|
||||
|
||||
- 标准 HTTP Handler/Middleware 桥接：跟踪 Raw 状态与提交，保留取消、流式能力和中间件跨请求状态；已提交响应不追加 JSON。
|
||||
- `.api` 支持动态 JSON `any` / `interface{}`，保持重复键、大小、外围未知字段校验和数字精度。
|
||||
- 路由级请求体限额、自定义绑定和 manual Handler；上传、原始 body、下载可保留手写实现，重生成受保护。
|
||||
- 自定义 scalar 显式对接项目 JSON/Text 方法；支持可空和集合，分别生成请求/响应 OpenAPI；不放宽其他字段。
|
||||
- 新增 [迁移扩展指南](MIGRATION.md)、可运行示例和真实生成项目回归。CLI 与框架依赖一起升级。
|
||||
|
||||
## v0.8.0-preview
|
||||
|
||||
- 公共响应 `codeType` 支持 `int32` / `int64` / `string`，校验默认码及映射范围，OpenAPI 标注整数位宽；JSON/YAML 和生成代码保留 int64 精度，旧 `integer` 兼容。
|
||||
- 公共 JSON 响应体改为可配置模板：支持嵌套结构、独立错误体、错误码类型/映射、提示与空值行为；旧 DTO 仅保留源代码兼容。
|
||||
- `.api` 支持 `response Name (...)`、分组引用和单路由覆盖；`@response raw` 输出原始业务 JSON。生成的模板、路由和 OpenAPI 使用同一份配置。
|
||||
- 提供应用级/接口级编码器，以及 Text / XML / Bytes 直接输出，允许三方回调独立控制成功和失败的状态、Header、内容。
|
||||
- 接口响应策略可在全局中间件之前挂载，覆盖提前鉴权/限流失败和 Context 克隆；内置路由 404/405 使用应用配置。
|
||||
- 详见 [公共响应体](RESPONSE.md)。CLI 与项目框架依赖需要一起升级到本版。
|
||||
|
||||
## v0.7.0-preview.1
|
||||
|
||||
- `.api` 支持集中业务错误目录、组级与路由级错误声明，生成状态/错误码/提示一致的 `internal/apierrors` 函数，以及 OpenAPI 命名响应示例。

# 已有 HTTP 项目逐步接入
|
||||
|
||||
从 `v0.9.0-preview` 开始，以下能力贯通运行时、`.api`、代码生成和 OpenAPI。CLI 和项目框架依赖一起升级；入口见 [README](README.md)。这些都是通用扩展点，框架不内置任何项目的 ID、支付回调、鉴权或数据库规则。
|
||||
|
||||
## 1. 保留标准 Handler 与中间件
|
||||
|
||||
```go
|
||||
app := omni.New(omni.WithLogger(true))
|
||||
app.Use(httpx.WrapMiddleware(existingMiddleware)) // func(http.Handler) http.Handler
|
||||
// go-zero 风格的 func(http.HandlerFunc) http.HandlerFunc：
|
||||
app.Use(httpx.WrapFuncMiddleware(existingFuncMiddleware))
|
||||
app.POST("/legacy", httpx.WrapHandler(http.HandlerFunc(existingHandler)))
|
||||
```
|
||||
|
||||
实际使用时先配置所有 `Use`，再注册路由。`WrapHandler` 也接受 `http.FileServer` 等标准 `http.Handler`。
|
||||
|
||||
- Handler 经过 App 的日志、requestId、恢复和应用中间件链，原来的 URL、状态码、Header、响应内容由它自己控制。
|
||||
- `c.Raw()` 的写入也会更新 `c.Status()` / `c.Responded()`；404 会记为 404。提交响应后返回错误或 panic，不会再追加错误 JSON。103 等临时响应不算最终提交。
|
||||
- 桥接器不缓存完整响应。下载继续流式复制；底层支持时保留 Flusher、Hijacker、Pusher、ReaderFrom、CloseNotifier。`http.ResponseController` 可沿 `Unwrap` 访问底层控制能力。能力仍取决于网络适配器和其他中间件。
|
||||
- 请求 context、取消信号和已有值继续传递，Omni 的路径参数可用 Go 1.22 的 `r.PathValue("id")` 读取。其他框架私有的参数读取器仍需由项目适配。标准中间件应从原 `r.Context()` 派生上下文；不能换成无关的 Background，也不能在 ServeHTTP 返回后调用 next。异步 timeout middleware 不在此桥接器的契约内。
|
||||
- 标准中间件在每条注册链构造一次，状态会跨请求保留。下游返回的错误在标准中间件退出前编码，因此压缩、审计等中间件能处理错误响应。它们自己的缓冲或改写行为仍由项目负责。
|
||||
|
||||
调用流使用 `App.Handle/GET/POST` 等入口即可，不要绕到原始 Router 注册。暂不使用 `.api` 的旧接口也能这样接入。
|
||||
|
||||
## 2. 动态 JSON：允许渐进补全 DTO
|
||||
|
||||
```go
|
||||
type LegacyReply {
|
||||
Data any `json:"data"`
|
||||
}
|
||||
```
|
||||
|
||||
`interface{}` 是 `any` 的等价写法，支持 `[]any`、`map[string]any` 和对应的 `interface{}` 写法。带方法的 interface 不支持，会提示明确的类型错误。
|
||||
|
||||
动态字段允许 object、array、string、number、bool、null；OpenAPI 字段 schema 为 `{}`，不假装知道内部结构。它放开的是**该字段的内容**，外围 DTO 未声明的字段仍被拒绝，JSON 重复键、深度、总大小限制仍生效。动态数字解析为 `json.Number`，避免大整数先转 float64 丢精度。原始 JSON 的空白、转义和字节布局不会保留；验签请走原始 body 入口。
|
||||
|
||||
这不会自动补齐缺少的业务路由，也不代表兼容全部 goctl 语法。能确定结构的新接口优先使用命名 DTO。
|
||||
|
||||
## 3. 按路由限制 body 与保留手写入口
|
||||
|
||||
普通 JSON 路由只声明需要的大小，不改变其他路由默认的 1 MiB：
|
||||
|
||||
```text
|
||||
@body (mode: json
|
||||
maxBytes: 2097152
|
||||
)
|
||||
@handler createItem
|
||||
post /items (CreateItemReq) returns (ItemResp)
|
||||
```
|
||||
|
||||
`maxBytes` 单位为字节，允许 1 至 1 TiB；不写时为 1 MiB。已知超长或读取未知长度/chunked body 超限都按 413 处理。内置 App/RouterGroup 在全局中间件读取前安装 reader 限额；同时保持接口响应策略。网络层若有更小限额，以更小值为准。手写 Handler 吞掉读取错误或已经提交响应后，框架不能重新改写 HTTP 状态，务必检查读取错误。
|
||||
|
||||
### 只替换绑定函数
|
||||
|
||||
```text
|
||||
@binding custom
|
||||
@body (mode: json
|
||||
maxBytes: 65536
|
||||
)
|
||||
@handler createItem
|
||||
post /items (CreateItemReq) returns (ItemResp)
|
||||
```
|
||||
|
||||
首次生成 `internal/handler/<group>/createItemBind.go`：
|
||||
|
||||
```go
|
||||
func (h *Handler) bindCreateItem(c *httpx.Context, req *types.CreateItemReq) error {
|
||||
// 调用项目自己的解码器，填充 req；失败返回 error。
|
||||
}
|
||||
```
|
||||
|
||||
Handler 继续调用 Service 并使用统一响应；只把绑定过程交给这个函数。初始 hook 返回 501，不能忽略实现。自定义绑定需自己实现 Content-Type、未知字段、尾部数据等校验，并遵守 DTO 文档；框架负责路由总大小限制，不隐式套第二次 JSON 绑定。
|
||||
|
||||
### 上传、原文验签、下载
|
||||
|
||||
```text
|
||||
@handlerMode manual
|
||||
@body (mode: multipart
|
||||
maxBytes: 10485760
|
||||
)
|
||||
@handler upload
|
||||
post /files
|
||||
|
||||
@handlerMode manual
|
||||
@body (mode: raw
|
||||
maxBytes: 65536
|
||||
)
|
||||
@produces "text/plain"
|
||||
@handler callback
|
||||
post /callback
|
||||
|
||||
@handlerMode manual
|
||||
@produces "application/octet-stream"
|
||||
@handler download
|
||||
get /download
|
||||
```
|
||||
|
||||
首次生成 `<operation>Manual.go`，由项目实现整个 `func(h *Handler) Callback(c *httpx.Context) error`；依赖通过 `h.deps` 访问。生成器保留路由、中间件与文档管理，不会预读、JSON 解码或重新包装手写输出，也不生成这个路由的 Service 方法。需要调用 Service 时自行组合。
|
||||
|
||||
- manual 无返回类型默认成功状态 200；也可 `returns (UploadResp)` 描述 JSON DTO，手写实现按声明调用 `c.OK` 等。`@produces` 用于无 DTO 的手写输出，描述成功响应媒体类型，不会自动设置运行时 Header。
|
||||
- raw 的文档为二进制请求体；multipart 为开放对象，具体文件字段与逐部分校验由项目实现。raw/multipart 请求 DTO 仅可含 path/form/header 字段，不能同时声明 JSON body 字段。`form` 始终指 URL query。
|
||||
- 原文验签直接读取 `c.Request().Body`，在声明的小限额内 `io.ReadAll`；大文件用 `MultipartReader` 配合 `io.Copy` 流式处理，不能整个读入内存。
|
||||
- 使用 `ParseMultipartForm` 时，其内存参数只是内存阈值，不是总上传限额。App/桥接器在请求结束（含错误和 panic）后删除临时文件；业务仍须关闭 `FormFile` 得到的文件。`MultipartReader` 不自动建临时文件，业务自行创建的文件由业务清理。
|
||||
- 手写 Handler 的成功输出由它控制；返回的 error、鉴权拒绝仍走接口的错误策略。三方若要求错误也返回指定文本，使用 [自定义 Encoder](RESPONSE.md#手写路由配置文件与三方回调) 并维护对应错误文档；`@produces` 不会改变错误协议。
|
||||
|
||||
直接注册 Go 路由：
|
||||
|
||||
```go
|
||||
app.HandleWithBodyLimit("POST", "/upload", 10<<20, nil, uploadHandler)
|
||||
// nil encoder 沿用 App 策略，也可传项目自己的 response.Encoder。
|
||||
```
|
||||
|
||||
通用注册器使用 `httpx.HandleWithBodyLimit(...)`；实现 `httpx.BodyLimitRegistrar` 可像 App 一样在全局中间件前限流量，未实现时只能在路由中间件入口限制。单独 `httpx.LimitBody` 同样受中间件顺序影响。
|
||||
|
||||
### 重新生成规则
|
||||
|
||||
`handlersGen.go`、`routesGen.go`、DTO、OpenAPI 继续由生成器管理；`*Bind.go`、`*Manual.go` 只首次创建，后续不会覆盖或删除。切换 manual 回自动模式时，先迁移实现并自行移除对应 Manual 文件，否则生成器明确拒绝，避免重复方法。修改 DTO 导致手写函数签名不匹配时，需要一起调整项目代码；`go test ./...` 是必要检查。
|
||||
|
||||
## 4. 自定义标量：项目定义行为，框架连接调用
|
||||
|
||||
例如输入 ID 兼容数字/字符串、输出统一为字符串：
|
||||
|
||||
```text
|
||||
scalar BusinessID (
|
||||
goImport: "example.com/billing/internal/ids"
|
||||
goType: ID
|
||||
jsonInput: string | int64
|
||||
jsonOutput: string
|
||||
text: true
|
||||
)
|
||||
type ItemReq {
|
||||
ID BusinessID `path:"id"`
|
||||
}
|
||||
type ItemResp {
|
||||
ID BusinessID `json:"id"`
|
||||
}
|
||||
```
|
||||
|
||||
`goImport`/`goType` 指向项目已有的具体 Go 类型，不是框架内置 ID。生成器创建类型别名和 `types.ContractScalars()`，然后把注册表显式传给每个 Binder。运行时使用标准接口：
|
||||
|
||||
| 项目类型的方法 | 用途 |
|
||||
| --- | --- |
|
||||
| 值接收者 `MarshalJSON() ([]byte, error)` | JSON 输出 |
|
||||
| 指针接收者 `UnmarshalJSON([]byte) error` | JSON 输入 |
|
||||
| 指针接收者 `UnmarshalText([]byte) error` | `text: true` 时的 path/query/header |
|
||||
|
||||
完整参考 [示例 ID 类型](examples/compatibility/ids/id.go)。CLI 校验声明并生成代码，不执行项目 Go 代码；启动时校验方法是否齐全，缺失会明确失败。
|
||||
|
||||
输入可选 `string`、`bool`、`int32`、`int64`、`float64`，用 `|` 声明多个允许的 JSON 类型；输出只声明一个。框架先校验 JSON 类型和数字范围，再调用项目转换方法。字符串是否是合法 ID、是否允许空串或负数由项目方法决定，不能把数字溢出静默截断。path/query/header 实际传输文本，OpenAPI 对这些位置描述 string；query 切片通过重复键传递。
|
||||
|
||||
普通字段不受注册影响，普通 `int64` 仍拒绝 JSON 字符串。没有全局注册表，也不会自动给所有 ID 放宽规则。标量可嵌套、放入切片/map，`*BusinessID` 允许 null；缺失默认必填，`optional`/`omitempty` 可选。标量的额外约束放在转换器中，目前不叠加 `binding`、default/options/range 等标签。
|
||||
|
||||
请求 OpenAPI 按 `string | int64` 生成 `anyOf`，响应按 `string` 生成，避免把输入兼容误描述为输出也有两种类型。输出方法必须遵守声明，框架不会每次重新验证响应；项目需为自定义类型测试边界行为。
|
||||
|
||||
不使用 `.api` 也可显式注册：
|
||||
|
||||
```go
|
||||
binder := contract.MustNew[CreateReq](
|
||||
contract.ScalarOf[ids.ID]("string|int64", "string", true),
|
||||
)
|
||||
// binder.Bind(c.Request(), httpx.RouteParams(c.Context()), &req)
|
||||
```
|
||||
|
||||
## 可运行示例与验收
|
||||
|
||||
```sh
|
||||
go run ./examples/compatibility
|
||||
curl -i http://127.0.0.1:8080/legacy
|
||||
curl -i -X POST http://127.0.0.1:8080/echo \
|
||||
-H 'Content-Type: application/json' -d '{"id":9223372036854775807,"data":{"hello":true}}'
|
||||
curl -i -F file=@README.md http://127.0.0.1:8080/upload
|
||||
curl -OJ http://127.0.0.1:8080/download
|
||||
```
|
||||
|
||||
完整契约：[compatibility.api](examples/contracts/compatibility.api)。生成项目起初的手写 hook 仍为 501；真实实现与原文 HMAC 验签回归见 [消费者 fixture](cmd/go-omni/apigen/testdata/compatibility)。
|
||||
|
||||
```sh
|
||||
GO_OMNI_SCAFFOLD_INTEGRATION=1 go test -race ./cmd/go-omni/apigen -run Compatibility
|
||||
go test -race ./httpx ./contract
|
||||
```
|
||||
|
||||
这些是框架验收，不代表任何业务项目已经迁移完毕；业务的路由覆盖、响应兼容、权限、资金事务和数据库行为需要业务自己的回归。

# 生成项目与文件维护边界
|
||||
|
||||
v0.13.0-preview 提供受管理的生成项目。安装同版远程 CLI，生成的项目直接引用该版本，无需本地 replace。根目录入口支持 `go run .` 和 `go build .`；框架本身仍然是可直接引用的库。安装和私有仓库访问见 [README](README.md#准备环境与安装)。
|
||||
|
||||
## 创建和日常开发
|
||||
|
||||
```sh
|
||||
# 在存放业务项目的目录执行，目标目录必须为空。
|
||||
go-omni new --module example.com/hello ./hello
|
||||
cd hello
|
||||
go mod tidy
|
||||
go run .
|
||||
go build .
|
||||
```
|
||||
|
||||
在项目目录使用同版 CLI：编辑 `api/service.api`，运行 `go-omni api generate`，填写 `internal/logic` 的业务方法。增加接口、分组或具名中间件会自动更新接入代码，无需修改入口。`--dry-run` 预览；`--check` 只读检查，包括 main、HTTP 接入和 OpenAPI。API 文件通过相对 import 拆分模块。
|
||||
|
||||
## 契约变更提示
|
||||
|
||||
生成器在 manifest 中保存上次成功生成的接口快照，比较请求/返回类型、嵌套 DTO 字段与标签、自定义 scalar、路径、body 模式/限额和流式输出类型。只提示受影响的接口，并标出业务文件；删除或移动接口会提醒整理保留的旧实现。注释、文件排版、Logic 参数名与导入别名不会被当成接口变化。
|
||||
|
||||
例如把 `GreetReq` 改名为 `HelloReq`，旧业务方法尚未修改时：
|
||||
|
||||
```text
|
||||
ERROR [logicSignature] internal/logic/greet/greet.go:12 (GET /api/greet/:name): ...
|
||||
before: Greet(context.Context, *types.GreetReq) (*types.GreetResp, error)
|
||||
after: Greet(context.Context, *types.HelloReq) (*types.GreetResp, error)
|
||||
```
|
||||
|
||||
| 命令 | 变更提示与检查行为 |
|
||||
| --- | --- |
|
||||
| `api generate --dry-run` | 显示计划、契约变化和业务签名问题，不写文件；诊断本身不让预览失败 |
|
||||
| `api generate` | 更新生成文件和契约快照，保留业务代码，并显示需要处理的诊断；生成成功不代表业务已通过编译 |
|
||||
| `api generate --check` | 只读检查；生成产物过期或发现明确的 Logic 签名/语法/重复方法错误时返回非零退出码 |
|
||||
| `api validate` | 只验证 `.api`，不检查项目 Go 实现 |
|
||||
|
||||
`REVIEW` 提醒复查业务语义；`ERROR` 表示已发现源代码问题。生成后，旧签名仍会在后续 `--check` 中报错，直到你改好；DTO 字段变化的 REVIEW 与上次生成快照比较，生成后不持续要求确认，也不会替你修改业务。业务方法移到同组其他 Go 文件时仍能定位。
|
||||
|
||||
这是轻量源码分析，不运行项目 init、不执行 Go 命令、不下载依赖。项目自定义类型别名、嵌入方法或 build tags 等无法可靠判断时，会给 REVIEW 并交给 Go 编译器验证；不把这些情况强行判为签名错误。它不检查方法体是否引用已删除字段，也不证明业务逻辑正确。CI 中应同时执行 `go-omni api generate --check` 和 `go test ./...`，按项目实际构建参数测试。当前版本首次接手缺少快照的 manifest v2 时，会明确提示建立基线，不猜测旧契约；Logic 签名检查仍会执行。
|
||||
|
||||
## 哪些文件由用户维护
|
||||
|
||||
| 文件 | 首次生成后由项目维护 |
|
||||
| --- | --- |
|
||||
| `api/*.api` | 路由、DTO、具名中间件、响应模板、请求/响应模式 |
|
||||
| `etc/config.yaml` | 运行参数；密钥通过环境变量提供 |
|
||||
| `internal/config/config.go` | 自定义配置字段、加载、默认值与校验 |
|
||||
| `internal/svc/serviceContext.go` | 依赖字段和初始化，持有加载后的 Config |
|
||||
| `internal/svc/options.go` | AppOptions、GlobalMiddleware；注册 Go 错误目录和全局扩展 |
|
||||
| `internal/svc/close.go` | 资源关闭；OnClose 为自定义资源提供标准清理入口 |
|
||||
| `internal/svc/storage.go` | 选用存储时生成，之后保留 |
|
||||
| `internal/logic/<group>/*.go` | 业务方法，使用标准 context.Context |
|
||||
| `internal/repository/<group>/*.go` | 数据访问，按需实现 |
|
||||
| `internal/middleware/<name>.go` | 项目鉴权/权限等具名中间件实现 |
|
||||
| 项目 Go 错误包 | 自行维护 Catalog 和常量，可跨服务共用 |
|
||||
| 自定义标量文件、`*Bind.go`、`*Manual.go` | 只有显式选择相应扩展时才生成/使用 |
|
||||
| 项目测试、迁移、部署脚本、go.mod/go.sum | 项目所有，生成器不重置其内容 |
|
||||
|
||||
以上骨架只补缺失文件，既有内容按字节保留。删除已废弃接口后，对应业务文件也不会被自动删除；由开发者整理编译器指出的失效类型或签名。
|
||||
|
||||
生成器持续管理：`main.go`、`internal/handler/*Gen.go`、分组的 `handlersGen.go`、`internal/types/*Gen.go`、中间件 `registryGen.go`、`docs/openapi.json`、`.goOmni/apiManifest.json`。如果在 `.api` 里选择声明错误，还会管理 `internal/apierrors/errorsGen.go`。文件标注 DO NOT EDIT；手改会被拒绝覆盖，需先移走自定义内容。
|
||||
|
||||
Logic 实例在注册时创建并由请求并发复用；请求数据用方法参数和局部变量传递，不存入共享 Logic/svc 字段。
|
||||
|
||||
普通 Handler 不需要维护。目录内可以同时有生成文件和单独的手写扩展文件，所有权按文件区分。没有额外 server 包或第二层 service。
|
||||
|
||||
## 依赖与启动扩展
|
||||
|
||||
`svc.New(ctx, logger, cfg)` 初始化依赖，可返回错误；Logger 由入口创建并借用。新增客户端时只需要扩展配置和 svc：
|
||||
|
||||
```go
|
||||
client, err := newClient(cfg.Client)
|
||||
if err != nil { return nil, err }
|
||||
c.Client = client
|
||||
c.OnClose(client.Close) // 创建成功后立即登记，后续失败也能释放
|
||||
```
|
||||
|
||||
`New` 的失败清理骨架已生成。OnClose 按登记的相反顺序执行；Close 幂等。项目不要重复关闭同一资源，借用的 Logger 也不应由 svc 关闭。构造器在返回错误前若创建了尚未交付的资源，该构造器自己负责释放。
|
||||
|
||||
错误注册写在 `internal/svc/options.go`，错误表可以来自任意项目共用包：
|
||||
|
||||
```go
|
||||
func (c *ServiceContext) AppOptions() []omni.Option {
|
||||
return []omni.Option{omni.WithErrors(apierrors.Catalog())}
|
||||
}
|
||||
```
|
||||
|
||||
业务调用 `omnierrors.ByCode(apierrors.CodeUsernameInvalid)`，可接 `WithParams` / `WithCause`。无需在 `.api` 重复错误目录。未声明独立错误目录的路由继承 App 目录；独立目录不与 App 合并。静态 OpenAPI 不执行 Go，不能自动枚举仅存在于 Go 中的错误目录。
|
||||
|
||||
`GlobalMiddleware()` 提供全局中间件；`Middlewares` 映射提供 `.api` 声明的具名中间件。全部显式调用，不依赖项目 init 注册，也不要求 svc 导入 handler。框架请求链按原有次序运行。
|
||||
|
||||
生成入口执行：配置加载/校验 → 日志 → svc.New → 生成的 handler.NewApp（应用 AppOptions、响应策略、校验最终 HTTP 配置、全局中间件、全部路由）→ App.RunContext → 依赖关闭 → 日志关闭。初始化失败、接入配置失败和监听失败也清理资源。
|
||||
|
||||
最终配置校验包含自定义响应编码器与错误目录的组合。码类型/映射冲突、编码器已绑定另一份目录等问题在创建 App 前返回错误，进入入口的清理流程，不等到构造 App 时才 panic。
|
||||
|
||||
日志在 AppOptions 前初始化，其配置应放在 Config 中。退出信号先触发 HTTP 排空；达到 shutdownTimeout 后按框架规则强制关闭连接。请求仍依赖的后台任务/客户端不能直接绑定信号 context 提前关闭，应持有独立生命周期，在 OnClose 中取消。业务必须响应请求 context 取消；忽略取消的 goroutine 无法保证在超时前结束。
|
||||
|
||||
## 依赖主动申请退出
|
||||
|
||||
从 v0.13.0-preview 起，生成的 svc 提供 `RequestShutdown(err)`。数据库客户端、节点租约、后台任务等发现不可恢复故障时，由项目决定是否退出：
|
||||
|
||||
```go
|
||||
// 在 svc 的依赖监控回调中调用；err 是实际故障原因。
|
||||
c.RequestShutdown(err)
|
||||
```
|
||||
|
||||
这只是通知，立即返回，不等待 HTTP 排空，也不直接关闭数据库。生成入口停止接收新请求，等待在途请求完成；超过 `shutdownTimeout` 后取消请求并关闭连接，再执行 svc.Close，最后关闭日志。非空故障原因保留在返回错误链中，进程退出码为 1；`RequestShutdown(nil)` 或正常 SIGINT/SIGTERM 在没有其他故障时退出码为 0。
|
||||
|
||||
多个依赖可并发通知，关闭流程仅执行一次，首个非空故障原因保留。正常信号已开始排空时收到的故障也不会被清理动作覆盖。初始化期间的通知同样有效，不依赖 HTTP 监听已经启动。业务应在 Close/OnClose 中停止并等待自己启动的监控任务，再结束资源清理；关闭完成以后才报告的故障无法参与已经结束的进程结果。
|
||||
|
||||
`Lifecycle *lifecycle.Controller` 是 svc 持有的通用控制器，初始化时创建，生成入口使用它的 Context。该 Context 表示服务正在停止，不代表数据库已经关闭。不能把它当作在途请求的 Context，也不要在它取消时立刻关闭请求仍依赖的资源。发号器失去租约后拒绝发号等业务安全规则仍由项目实现。
|
||||
|
||||
## 配置内置接口
|
||||
|
||||
生成项目在 `etc/config.yaml` 明确列出以下默认配置；可以独立关闭、修改路径，或让健康接口返回原始 JSON：
|
||||
|
||||
```yaml
|
||||
server:
|
||||
endpoints:
|
||||
liveness:
|
||||
enabled: true
|
||||
path: /health/live
|
||||
responseMode: app
|
||||
readiness:
|
||||
enabled: true
|
||||
path: /health/ready
|
||||
responseMode: app
|
||||
openapi:
|
||||
enabled: true
|
||||
path: /openapi.json
|
||||
```
|
||||
|
||||
`responseMode: app` 使用项目 App 的响应模板/自定义 Encoder。健康成功使用项目成功码和成功提示；未就绪的 `NOT_READY` 可在项目 Go 错误目录配置业务码和公开提示，无需在 `.api` 再声明。
|
||||
|
||||
健康探针的 HTTP 状态固定遵循探针语义：存活/就绪为 200，未就绪为 503；项目错误目录或自定义编码器不能把未就绪改为 HTTP 200。响应模板 `${status}` 同样使用探针状态。失败继续进入业务失败日志/指标，探针底层原因保留在错误链供日志使用，不直接返回给调用方。
|
||||
|
||||
`responseMode: raw` 返回 `{"status":"ready"}` 等健康数据，有依赖时包含检查名称、结果与耗时；不包装公共体。存活检查不执行依赖探针；服务开始退出后，就绪检查返回 503，存活仍可返回 200，直到监听关闭。OpenAPI 始终输出规范文档本身，不使用业务响应包装；关闭 HTTP 文档端点不影响生成 `docs/openapi.json`。
|
||||
|
||||
环境变量覆盖配置文件，例如 `GO_OMNI_ENDPOINTS_READINESS_PATH=/readyz`、`GO_OMNI_ENDPOINTS_READINESS_RESPONSE_MODE=raw`、`GO_OMNI_ENDPOINTS_OPENAPI_ENABLED=false`；liveness/readiness/openapi 都支持对应的 ENABLED 和 PATH。Config/AppOptions 的最终有效配置决定是否注册。
|
||||
|
||||
关闭或改名后，旧路径不再由框架保留，项目可以在 `.api` 自己声明。启用的内置 GET 路由与业务路由相同或被业务参数/通配路径覆盖时，在创建 App、开始监听之前报错；不会覆盖业务路由。内置接口仍经过全局中间件；项目在鉴权中间件中明确决定这些路径的访问规则，框架不自动绕过鉴权。
|
||||
|
||||
## 从 v0.12 生成项目升级
|
||||
|
||||
manifest v2 和现有目录保留。升级同版 CLI 与框架依赖后执行 `api generate`，生成器自动更新 main 和 Handler；`svc`、配置与业务文件仍按字节保留，所以需要在项目拥有的 svc 文件补入以下扩展：
|
||||
|
||||
1. `serviceContext.go` 导入 `git.yuntuo.hk/k2safe/go-omni/lifecycle`，给 ServiceContext 增加 `Lifecycle *lifecycle.Controller`；创建 c 时用 `lifecycle.New(ctx)` 初始化，并在后续依赖初始化前设置 `ctx = c.Lifecycle.Context()`。
|
||||
2. 增加 `func (c *ServiceContext) RequestShutdown(err error) { c.Lifecycle.RequestShutdown(err) }`。
|
||||
3. 构造失败的 defer 在 `c.Close()` 后保留 `c.Lifecycle.Err()`；Close 的 `closeOnce.Do` 开头调用 `c.Lifecycle.RequestShutdown(nil)`，重复关闭仍由已有 once 保护。
|
||||
4. 配置默认值若来自 `config.Default()`，自动具有默认端点配置；如需禁用或改路径，在 YAML 或项目 Config 中显式设置。手动拼 Config 的项目需要自行填写要启用的端点。
|
||||
|
||||
精确实现可对照 [示例 svc](examples/managedService/internal/svc/serviceContext.go) 和 [关闭逻辑](examples/managedService/internal/svc/close.go)，也可在临时目录用新版 CLI 生成参考。不要覆盖原有数据库/客户端初始化；不需要手改 main、Handler 或引入另一套启动器。最后执行 `api generate --check`、`go test ./...`、`go build .`，并验证故障退出。
|
||||
|
||||
## App 默认响应格式
|
||||
|
||||
在 **入口** `.api` 声明一次：
|
||||
|
||||
```text
|
||||
@app (
|
||||
defaultResponse: CommonResponse
|
||||
)
|
||||
response CommonResponse (
|
||||
codeType: int32
|
||||
successCode: 0
|
||||
errorCode: 9999
|
||||
messageField: msg
|
||||
dataMode: always
|
||||
)
|
||||
```
|
||||
|
||||
优先级：路由 `@response` → 分组 `@server(response: ...)` → App 默认。模板可以定义在 import 文件里，`@app` 只能在入口声明。重复声明、引用不存在的模板会报错；不会按文件顺序猜默认值。未声明 `@app` 时使用框架现有默认格式。
|
||||
|
||||
生成的 App 普通路由、404/405、未单独指定格式的生成路由共用默认模板。已匹配路由的中间件提前报错也使用路由策略。`@response raw` 的成功 JSON 不包装，错误沿用有效模板。
|
||||
|
||||
显式 `.api` 默认响应优先于 Config/AppOptions 中的响应配置，保持接口文档和实际响应一致。其他 AppOptions 继续生效；要改变格式就修改 `.api`。项目无需访问 handler 私有变量。
|
||||
|
||||
## 自动上传、回调与下载
|
||||
|
||||
以下声明生成完整 Handler，用户填写 Logic：
|
||||
|
||||
```text
|
||||
@handler upload
|
||||
@body (mode: multipart; maxBytes: 33554432)
|
||||
post /upload returns (UploadResp)
|
||||
|
||||
@handler callback
|
||||
@body (mode: raw; maxBytes: 65536)
|
||||
@produces "text/plain"
|
||||
post /callback
|
||||
|
||||
@handler download
|
||||
@produces "application/octet-stream"
|
||||
get /download (DownloadReq)
|
||||
```
|
||||
|
||||
- raw/multipart 的 Logic 增加 `body *httpx.Body` 参数。`body.Raw` 是受路由上限约束的原始字节流；`body.Header` 是请求头副本。
|
||||
- multipart 用 `body.Parts.NextPart()` 顺序读取，关闭每个 Part；不调用 ParseMultipartForm，不产生上传临时文件，也不把整个文件放入内存。每个字段/文件的业务要求由 Logic 校验。请求 DTO 可定义 path/form/header；`form` 仍是 URL 查询参数，不能用 json DTO 重复读取上传体。
|
||||
- Parts 是 `*httpx.MultipartReader`，返回的 `*httpx.MultipartPart` 提供 Read、Close、Header、FormName、FileName；NextRawPart 可读取未做 quoted-printable 解码的部分。NextPart 自动关闭上一个未读完的 Part；Close 会报告读取错误。不要混用 Parts 与 Raw 读取同一个 multipart 请求。
|
||||
- multipart 缺少结束边界、头部/内容损坏默认返回 `400 / INVALID_MULTIPART`；超过路由限额仍为 413，媒体类型/缺少 boundary 为 415。框架只提供通用标识和默认提示，项目可以在 Go 错误目录中配置自己的状态、业务码和文案。内部解析原因保留在错误链，不进入公开响应；Logic 自己返回的数据库等错误不会被统一改成 400。
|
||||
- raw 数据不经过 JSON 解码。签名算法、密钥及回执内容由业务提供；同一个流只消费一次。若中间件先读取验签，项目必须显式使用受限缓冲/重放，生成器不会自动缓存大文件。
|
||||
- `@produces` 使 Logic 返回 `(*httpx.Stream, error)`，其中 Content 是 `io.ReadCloser`，可选 Name 生成附件下载头。ContentType 可携带 charset，但必须与契约媒体类型匹配。Handler 负责关闭内容流，无公共体包装；写出后发生错误不会追加 JSON。
|
||||
- Handler 在成功响应前检查剩余请求流，包含未读完的 multipart 部分、最终边界和请求体上限；已经遇到的 multipart 读取错误不会因业务忽略它而变成成功。读取失败和 413 不能撤回 Logic 已产生的外部副作用；重要业务应先调用 `body.Complete()` 确认完整读取/验证，再提交事务或发布文件。Complete 可重复调用。
|
||||
- 自动 Handler 采用先完成输入、再发送输出的顺序；不要把正在读取的 body.Raw 直接当作 Stream.Content 返回。需要同时读写请求/响应的协议时使用手写扩展。
|
||||
- 大文件的耗时仍受 HTTP 读写超时约束。按接口需要配置，框架不自动无限延长。
|
||||
|
||||
默认请求体上限为 1 MiB，按路由设置 maxBytes，不能通过统一放大全局限制替代。`@produces` 仅声明媒体类型，不保证业务返回的内容符合该媒体的语义。Range、SSE 刷新、特殊协议等需要时仍可显式选 `@handlerMode manual`；它是可选扩展，不是普通上传下载的前置条件。
|
||||
|
||||
## 旧结构处理
|
||||
|
||||
新生成器使用 manifest v2，不兼容原 settings/servicecontext/service 与 cmd/server 布局。已有旧目录会报错，不能通过覆盖 main 自动迁移。试验代码需保留时，在新目录生成，移动 `.api`、Logic、配置和 svc 扩展并调整导入；独立的 `cmd/migrate` 等工具由项目维护。不会静默覆盖手写 main 或删除无关命令。
|
||||
|
||||
`go-omni new` 与 `api new` 统一使用此结构。受管理项目通过 `.api` 增加模块，旧的 `add` 手动模块装配方式不适用于该结构。直接引用 go-omni 框架包的项目不受这些目录约定约束。
|
||||
|
||||
## 已有服务接入步骤
|
||||
|
||||
每个独立服务生成一个项目，module 名称、上层目录和共享业务包由项目选择。接入时固定 CLI 与框架版本为 v0.13.0-preview：
|
||||
|
||||
1. 先保留旧服务，整理实际路由及现有响应、鉴权和超时要求。在新目录执行 `go-omni new --api /path/to/service.api --module example.com/service ./service`；不对旧入口强制覆盖。
|
||||
2. 在 `.api` 中选择 `@app(defaultResponse: ...)`，显式保留原项目的字段、成功码、错误码和 `dataMode`。需要独立回执的路由单独声明 raw/produces。普通路由、404/405 和提前返回的中间件一起验收。
|
||||
3. 把配置放入 `internal/config` 和 `etc/config.yaml`；数据库、自定义 Connector、Redis、ID Client 等依赖放入 `internal/svc`，初始化成功后立即 `OnClose`。现有事务和迁移工具继续由项目维护；数据库扩展见 [database](database/README.md)。
|
||||
4. 业务错误目录只在项目 Go 包维护，通过 `svc.AppOptions()` 返回 `omni.WithErrors(apierrors.Catalog())` 注册一次。需要继承 App 目录的路由不要重复声明独立错误目录。项目鉴权放入中间件，业务实现迁入 Logic/Repository；无需修改 main 或生成的 Handler。
|
||||
5. 上传、原始请求体验签和下载优先使用自动 Handler；只有特殊协议才选择手写扩展。保留实际验签算法、流式处理、大小限制和存储权限，按 [迁移扩展](MIGRATION.md) 处理旧 Handler 与自定义标量。
|
||||
6. 每个服务运行下面的检查，再用实际配置验证依赖连通、启动失败清理和正常退出。业务侧补充原有接口兼容、鉴权、事务回滚与实际上传下载回归；框架测试不能代替这些业务验收。
|
||||
|
||||
```sh
|
||||
go mod tidy
|
||||
go-omni api validate
|
||||
go-omni api generate --check
|
||||
go test ./...
|
||||
go build .
|
||||
go run .
|
||||
```
|
||||
|
||||
后续增加接口修改 `.api` 并重新生成；增加依赖修改配置和 svc。将契约、生成文件、manifest 与业务代码一起提交。完整流程不需要项目另外维护启动器，也不需要读取 handler 的私有变量。

# GoOmni
|
||||
|
||||
GoOmni 是一套面向业务复用的 Go 后端基础框架。当前默认使用只依赖标准库的网络适配器，业务代码只依赖 GoOmni 的 transport-neutral API，后续可以替换为自研网络层。
|
||||
GoOmni 是面向多个业务项目复用的 Go 后端框架：用 `.api` 定义接口、请求和返回类型，生成项目目录、HTTP 接入代码及 OpenAPI，业务代码负责 Logic 和 Repository。也可以在已有项目中直接使用 `omni.New()`，或单独引入日志、存储等模块。
|
||||
|
||||
远程 module 地址是 `git.yuntuo.hk/k2safe/go-omni`。业务项目可以直接引用指定版本：
|
||||
**从这份 README 开始接入。** 当前版本 **`v0.13.0-preview`**，新生成项目采用根目录入口和 `config / svc / logic / handler`。可以固定版本开展业务接入；文件维护边界和已有服务迁移步骤见 [项目指南](PROJECT.md)，版本变化与验收见 [发布说明](RELEASE.md)。
|
||||
|
||||
Go **1.22+**。框架不依赖 Gin，默认使用标准库网络层，提供可切换的 native HTTP/1.1 和实验性 HTTP/2 适配器。
|
||||
|
||||
响应字段、业务码、登录方式、权限规则和数据库表结构由接入项目决定。文中的 `code/msg/data`、`200/9999` 都是示例配置，可以替换。
|
||||
|
||||
## 选择接入方式

|
||||
|
||||
## 准备环境与安装
|
||||
|
||||
module 地址是 `git.yuntuo.hk/k2safe/go-omni`。先确保本机 Go 和 Git 可用，并具有仓库读取权限；使用自己的 Git 凭据管理器，不把账号或 Token 写进 module 地址。
|
||||
|
||||
安装固定版本的 CLI，后面的命令继续使用同一终端。私有 module 加入 GOPRIVATE，保留已有配置：
|
||||
|
||||
```sh
|
||||
go get git.yuntuo.hk/k2safe/go-omni@v0.7.0-preview.1
|
||||
export GOPRIVATE="$(go env GOPRIVATE),git.yuntuo.hk"
|
||||
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.13.0-preview
|
||||
export PATH="$(go env GOPATH)/bin:$PATH"
|
||||
go-omni --help
|
||||
```
|
||||
|
||||
`v0.4.0` 移除了 Gin 和 Gin 专属的 `WithMode` 配置；`omni.New()` 直接使用标准库路由，已有业务 Handler / Service 无需修改。
|
||||
如果设置过 GOBIN，将该目录加入 PATH。远程 CLI 默认引用自身版本的框架，生成的 go.mod 不需要本地 replace。开发者与 CI 使用同版 CLI；框架源码开发方式见 [CLI 文档](cmd/go-omni/README.md#版本与迁移)。
|
||||
|
||||
创建新业务项目：
|
||||
## 新项目：生成并运行
|
||||
|
||||
在准备存放业务项目的目录执行，`./hello` 必须是新目录或空目录；把 `example.com/hello` 换成自己的 Go module 名称。
|
||||
|
||||
```sh
|
||||
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.7.0-preview.1
|
||||
go-omni new --module example.com/billing ./billing
|
||||
cd billing
|
||||
go-omni api new --module example.com/hello ./hello
|
||||
cd hello
|
||||
go mod tidy
|
||||
go run ./cmd/server
|
||||
go run .
|
||||
```
|
||||
|
||||
远程安装的 CLI 默认引用自身版本，生成的项目不需要本地 `replace`。
|
||||
具体版本和本地开发选项见 [CLI 文档](cmd/go-omni/README.md)。
|
||||
|
||||
需要数据库持久化时，使用 `go-omni new --database mysql --module example.com/billing ./billing`。
|
||||
生成项目包含完整用户 CRUD、数据库 Repository、ServiceContext、建表脚本和就绪探针。
|
||||
先应用生成的 `schema.sql`，再配置 `GO_OMNI_DB_DSN`；启动时会检查连接与表结构，退出时释放连接池。
|
||||
|
||||
## API 定义与项目生成
|
||||
|
||||
当前源码新增 **API 定义驱动项目生成**：写 `.api` 定义请求、响应和路由，自动生成项目目录、DTO、Handler、Service 骨架及 OpenAPI。重复生成保留业务代码，支持只读 CI 检查，完整语法和示例见 [API 开发指南](API.md)。
|
||||
另开终端验证：
|
||||
|
||||
```sh
|
||||
go run ./cmd/go-omni api new --framework-dir . \
|
||||
--module example.com/omniDemo ../omniDemo
|
||||
curl -i http://127.0.0.1:8080/api/greet/Alice
|
||||
curl -i http://127.0.0.1:8080/health/ready
|
||||
curl -sS http://127.0.0.1:8080/openapi.json
|
||||
```
|
||||
|
||||
API 生成支持 `--database mysql --storage local --log-output file` 组合初始化。上面的命令使用本地源码；远程安装见 [发布说明](RELEASE.md)，完整业务案例见 [userService](examples/userService/README.md)。
|
||||
第一个接口返回 HTTP 200，业务数据为 `{"message":"Hello Alice"}`。初始模板未配置响应格式，使用默认公共体：
|
||||
|
||||
## 目录结构
|
||||
```json
|
||||
{"code":"OK","message":"success","data":{"message":"Hello Alice"},"requestId":"本次请求编号"}
|
||||
```
|
||||
|
||||
按 Ctrl+C 停止服务。进入项目目录即可 `go build .`；该示例不需要数据库或其他外部服务。

main 分支新增缓存、出站 HTTP、限流/幂等/超时中间件、后台任务和 `go-omni add` 模块脚手架。
|
||||
使用方式、默认容量和进程内能力的适用范围见 [业务基础模块](MODULES.md)，
|
||||
可以直接运行 [组合示例](examples/modules/README.md)。这些能力从 `v0.7.0-preview` 提供。
|
||||
修改 `api/service.api` 后重新生成，业务写在 `internal/logic`，数据访问写在 `internal/repository`，依赖在 `internal/svc` 装配。声明业务错误后还会生成 `internal/apierrors/errorsGen.go`。
|
||||
|
||||
扩展模块还包括 JWT/Session、Policy、文件配置及安全热更新、Redis 共享中间件、持久队列、多平台对象存储、OpenAPI、OpenTelemetry、熔断、迁移、审计和分页。
|
||||
使用与边界见 [扩展模块](ADVANCED.md)，可运行 [文件服务组合示例](examples/platform/README.md)。go-omni 不集成 Orbit；需要流程编排的业务项目独立接入。
|
||||
`api new` 的问候接口可以直接运行；自定义接口新生成的 Logic 和鉴权 hook 返回 **501**，需要实现后才可用。生成器不会根据 HTTP 字段猜数据库表或业务规则。
|
||||
|
||||
## 快速开始
|
||||
### 从自己的接口定义生成
|
||||
|
||||
保存下面的完整示例为 `catalog.api`，再执行后面的生成命令。这里的响应格式、错误码和提示都由这个业务项目定义。
|
||||
|
||||
```text
|
||||
syntax = "v1"
|
||||
|
||||
@app (defaultResponse: CommonResponse)
|
||||
|
||||
response CommonResponse (
|
||||
body: {"code":"${code}", "msg":"${message}", "data":"${data}"}
|
||||
codeType: int32
|
||||
successCode: 200
|
||||
errorCode: 9999
|
||||
successMessage: "操作成功"
|
||||
dataMode: always
|
||||
codes: {"ITEM_NOT_FOUND":404001}
|
||||
)
|
||||
|
||||
error ItemNotFound 404 "ITEM_NOT_FOUND" "记录不存在"
|
||||
|
||||
type GetItemReq {
|
||||
ItemID string `path:"itemId" binding:"required"`
|
||||
}
|
||||
type ItemResp {
|
||||
ItemID string `json:"itemId"`
|
||||
Name string `json:"name"`
|
||||
}
|
||||
|
||||
@server (
|
||||
group: item
|
||||
prefix: /api/v1
|
||||
response: CommonResponse
|
||||
)
|
||||
service catalog-api {
|
||||
@doc "查询商品"
|
||||
@errors ItemNotFound
|
||||
@handler getItem
|
||||
get /items/:itemId (GetItemReq) returns (ItemResp)
|
||||
}
|
||||
```
|
||||
|
||||
```sh
|
||||
go-omni api validate --api catalog.api
|
||||
go-omni new --api catalog.api \
|
||||
--module example.com/catalog ./catalog
|
||||
cd catalog
|
||||
go mod tidy
|
||||
```
|
||||
|
||||
将生成的 `internal/logic/item/getItem.go` 替换为下面的演示实现。实际业务中换成 Repository 查询，Logic 返回业务数据或错误，不再手工包装公共体：
|
||||
|
||||
```go
|
||||
package item
|
||||
|
||||
import (
|
||||
"context"
|
||||
|
||||
"example.com/catalog/internal/apierrors"
|
||||
"example.com/catalog/internal/types"
|
||||
)
|
||||
|
||||
func (s *Logic) GetItem(ctx context.Context, req *types.GetItemReq) (*types.ItemResp, error) {
|
||||
if req.ItemID != "1001" {
|
||||
return nil, apierrors.ItemNotFound()
|
||||
}
|
||||
return &types.ItemResp{ItemID: req.ItemID, Name: "示例商品"}, nil
|
||||
}
|
||||
```
|
||||
|
||||
示例 import 对应上面的 `example.com/catalog`，使用其他 module 名称时同步替换。启动后，在另一个终端验证：
|
||||
|
||||
```sh
|
||||
# catalog 项目目录中启动；先停掉前面的 hello 服务，释放 8080 端口。
|
||||
go run .
|
||||
# 另一个终端：
|
||||
curl -i http://127.0.0.1:8080/api/v1/items/1001
|
||||
curl -i http://127.0.0.1:8080/api/v1/items/missing
|
||||
```
|
||||
|
||||
成功时得到 `{"code":200,"msg":"操作成功","data":{"itemId":"1001","name":"示例商品"}}`；不存在时为 HTTP 404、`{"code":404001,"msg":"记录不存在","data":null}`。
|
||||
|
||||
需要 MySQL、文件存储或文件日志时，**首次生成**可以使用：
|
||||
|
||||
```sh
|
||||
go-omni new --api catalog.api \
|
||||
--module example.com/catalogFull --database mysql --storage local \
|
||||
--log-output file --log-format json ./catalogFull
|
||||
```
|
||||
|
||||
该命令在 `catalog.api` 所在目录执行，目标仍需是新目录。数据库迁移、表结构和 Repository 由项目维护，API 模板不自动建表；MySQL DSN 通过 `GO_OMNI_DB_DSN` 提供。存储还可选 `s3`、`r2`、`oss`，按生成项目的配置说明提供桶、端点和凭据。完整生成项目示例见 [managedService](examples/managedService/README.md)。
|
||||
|
||||
`go-omni new` 与 `go-omni api new` 统一生成契约项目。需要手写项目时，可直接引用框架包；生成器不再提供另一套 CRUD 启动目录。
|
||||
|
||||
## 已有项目：按模块接入
|
||||
|
||||
在业务项目的 **go.mod 所在目录**执行：
|
||||
|
||||
```sh
|
||||
go get git.yuntuo.hk/k2safe/go-omni@v0.13.0-preview
|
||||
```
|
||||
|
||||
已有项目可直接复用现有目录、Service、Repository 和数据库连接，先选择一个接口接入。也可以只用 `logx`、`storage` 等包，暂时保留原来的 HTTP 框架。希望入口和 HTTP 接入都交给生成器的项目，按 [已有服务接入步骤](PROJECT.md#已有服务接入步骤) 在新目录生成后迁入业务代码。
|
||||
|
||||
下面是可独立运行的 `main.go` 示例；迁入现有项目时，把路由调用接到自己的业务服务即可。
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import omni "git.yuntuo.hk/k2safe/go-omni"
|
||||
|
||||
func main() {
|
||||
app := omni.New()
|
||||
|
||||
app.GET("/health", func(ctx *omni.Context) error {
|
||||
return ctx.OK(map[string]string{"status": "ok"})
|
||||
})
|
||||
|
||||
app.Run(":8080")
|
||||
}
|
||||
```
|
||||
|
||||
成功响应默认使用统一结构：
|
||||
|
||||
```json
|
||||
{
|
||||
"code": "OK",
|
||||
"message": "success",
|
||||
"data": {"status": "ok"},
|
||||
"requestId": "..."
|
||||
}
|
||||
```
|
||||
|
||||
业务错误可以直接返回：
|
||||
|
||||
```go
|
||||
return omni.NotFound("USER_NOT_FOUND", "user was not found")
|
||||
```
|
||||
|
||||
默认网络适配器位于 `transport/nethttp`。业务层不需要导入具体网络库；如果后续实现自己的网络层，只需要实现 `httpx.Router` / `httpx.RouterGroup`，然后通过 `omni.NewWithRouter` 启动应用：
|
||||
|
||||
```go
|
||||
application := omni.NewWithRouter(myRouter)
|
||||
```
|
||||
|
||||
仓库还提供了使用标准库路由的 `transport/nethttp` 参考实现。两种适配器已通过同一套路由、业务处理链和取消传播测试，完整用户 CRUD 复用同一份 Handler / Service。
|
||||
|
||||
自研适配器可以直接运行 `transport/transporttest.Run` 验收。具体规则、v0.4.0 的斜杠 / Any / 405 行为调整，以及自研网络内核与当前 HTTP 接口的边界，见 [适配层契约](transport/README.md)。
|
||||
|
||||
`app.Engine()` 返回标准 `http.Handler`，`ctx.Raw()` 返回适配器提供的 `http.ResponseWriter`，业务 API 不锁定具体网络实现。
|
||||
|
||||
需要试用第一版自研网络层时，业务注册代码无需改变，只替换启动器：
|
||||
|
||||
```go
|
||||
import (
|
||||
"context"
|
||||
"log"
|
||||
"os"
|
||||
"os/signal"
|
||||
"syscall"
|
||||
"log"
|
||||
"net/http"
|
||||
|
||||
omni "git.yuntuo.hk/k2safe/go-omni"
|
||||
"git.yuntuo.hk/k2safe/go-omni/transport/native"
|
||||
omni "git.yuntuo.hk/k2safe/go-omni"
|
||||
"git.yuntuo.hk/k2safe/go-omni/logx"
|
||||
"git.yuntuo.hk/k2safe/go-omni/response"
|
||||
)
|
||||
|
||||
ctx, cancel := signal.NotifyContext(context.Background(), os.Interrupt, syscall.SIGTERM)
|
||||
defer cancel()
|
||||
func main() {
|
||||
if err := run(); err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
}
|
||||
|
||||
app := omni.New()
|
||||
app.GET("/health", func(ctx *omni.Context) error {
|
||||
return ctx.OK(map[string]string{"status": "ok"})
|
||||
})
|
||||
if err := app.RunWith(ctx, native.New(nil), ":8080"); err != nil {
|
||||
log.Fatal(err)
|
||||
func run() error {
|
||||
closeLog, err := logx.Setup(logx.Config{
|
||||
Service: "catalog", Level: "info", Format: "json", Output: "stdout",
|
||||
})
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
defer closeLog()
|
||||
|
||||
app := omni.New(
|
||||
omni.WithLogger(true),
|
||||
omni.WithResponse(response.Config{
|
||||
Body: map[string]any{
|
||||
"code": "${code}", "msg": "${message}", "data": "${data}",
|
||||
},
|
||||
CodeType: "int32", SuccessCode: 200, ErrorCode: 9999,
|
||||
SuccessMessage: "操作成功", DataMode: "always",
|
||||
Codes: map[string]any{"ITEM_NOT_FOUND": 404001},
|
||||
}),
|
||||
)
|
||||
app.GET("/api/v1/items/:itemId", func(c *omni.Context) error {
|
||||
itemID := c.Param("itemId")
|
||||
logx.InfoContext(c.Context(), "item.get", "itemId", itemID)
|
||||
if itemID != "1001" {
|
||||
return omni.NotFound("ITEM_NOT_FOUND", "记录不存在")
|
||||
}
|
||||
return c.OK(map[string]string{"itemId": itemID, "name": "示例商品"})
|
||||
})
|
||||
// 第三方协议可明确输出文本，不经过公共 JSON 包装。
|
||||
app.GET("/ping", func(c *omni.Context) error {
|
||||
return c.Text(http.StatusOK, "pong")
|
||||
})
|
||||
return app.Run("127.0.0.1:8080")
|
||||
}
|
||||
```
|
||||
|
||||
`transport/native` 当前支持 HTTP/1.1、Keep-Alive、`Content-Length` 和 chunked 请求体、`http.Flusher` 流式响应、可选 TLS、读写超时和优雅关闭；不支持的传输编码会被拒绝。它会复用连接状态和响应对象，并可通过 `MaxConnections`、`MaxConcurrentRequests` 限制内存峰值。它仍通过标准 HTTP 请求/响应接口连接业务层，适合在现有 Handler / Service 上做网络层验证。
|
||||
运行 `go run .`，访问 `/api/v1/items/1001`、`/api/v1/items/missing` 和 `/ping`，可分别验证成功、业务错误及纯文本输出。`App` 实现标准 `http.Handler`，也可挂进现有 `http.Server` 或父路由；这时监听、TLS、信号和资源关闭由现有入口负责，结束时调用 `app.Close()`。
|
||||
|
||||
native TLS 当前只支持并宣告 ALPN `http/1.1`；配置 `h2` 会在启动时快速失败。需要 HTTP/2 时，可由 Nginx/Cloudflare 终止后回源 HTTP/1.1，或使用默认的 `transport/nethttp` 适配器。
|
||||
现有 `http.HandlerFunc` 可直接通过 `app.POST("/legacy", httpx.WrapHandler(http.HandlerFunc(oldHandler)))` 接入；状态码与访问日志一致，下载和流式输出保持原协议。标准中间件、动态 JSON、上传/原文 body、手写绑定和自定义类型的完整用法见 [迁移扩展指南](MIGRATION.md)。
|
||||
|
||||
`transport/http2` 是独立的 opt-in 实验适配器，使用 `x/net/http2` 处理帧和流控，同时保留 GoOmni 的连接上限、全局请求并发闸门和生命周期边界。它不会改变 native 默认路径；实验入口、限制和验收结果见 [HTTP/2 进入条件](transport/native/HTTP2.md)。
|
||||
接入现有业务时，逐项确认：
|
||||
|
||||
自研网络层还提供 `server.Stats()`，可读取 accepted、rejected、active connections 和 active requests，与上面的业务请求 metrics 组合后能区分连接堆积、过载拒绝和 Handler 慢请求。`rejectedConnections` 表示连接闸门拒绝数，`rejectedRequests` 表示并发请求闸门返回 503 的次数。
|
||||
- **协议**：保留既有 URL、HTTP 状态、字段、分页和空值语义。已有业务错误类型需要在项目内转换为 Omni 错误，或使用 `WithResponseEncoder` 适配原错误；设置字段模板不会自动识别其他库的错误。
|
||||
- **鉴权**：把现有登录态和权限校验接入中间件，继续使用原来的授权范围和业务规则。原来依赖 `gin.Context` 等类型的 HTTP 代码需要适配；标准 `context.Context` 的业务服务可以继续复用。
|
||||
- **数据类型**：ID、金额、日期等按项目协议转换。用 `.api` 的 `scalar` 显式关联项目自己的类型与 JSON/Text 转换方法，分别声明输入和输出协议；普通字段保持严格绑定，见 [自定义标量](MIGRATION.md#4-自定义标量项目定义行为框架连接调用)。
|
||||
- **生成器**：它不会自动接管任意已有 Go 项目。希望引入 `.api` 时，先在独立新目录生成对照，再规划路由与生成目录的接入，不要用脚手架覆盖现有业务目录。
|
||||
|
||||
业务代码可以直接使用 `git.yuntuo.hk/k2safe/go-omni/logx` 打结构化日志，不需要依赖具体网络库：
|
||||
先通过一个接口的成功、参数错误、未登录、无权限及业务错误回归，再按模块迁移。框架不要求所有项目使用同一套业务目录或身份模型。
|
||||
|
||||
```go
|
||||
func (s *UserService) Create(ctx *httpx.Context) error {
|
||||
logx.InfoContext(ctx.Context(), "user.create", "email", input.Email)
|
||||
return nil
|
||||
}
|
||||
```
|
||||
## 配置公共响应与独立协议
|
||||
|
||||
需要基础运行指标时，可以注册 transport-neutral metrics middleware 和接口：
|
||||
|
||||
```go
|
||||
requestMetrics := omni.NewMetrics()
|
||||
app.Use(requestMetrics.Middleware())
|
||||
app.GET("/metrics", requestMetrics.Handler())
|
||||
```
|
||||
|
||||
接口返回请求总数、错误数、当前处理中请求、累计耗时和 HTTP 状态分布。它是进程内快照，生产环境可由业务侧定时采集到监控系统。
|
||||
|
||||
`WithLogger(true)` 会启用 GoOmni 的统一 HTTP 访问日志；日志内容和业务日志共用 `requestId`。应用启动时可以调用 `logx.Setup` 配置 JSON/文本格式、级别、服务名和输出文件。文件轮转、敏感字段脱敏、异常堆栈与慢请求配置见 [logx 文档](logx/README.md)；文件直传与云端分片上传见 [storage 文档](storage/README.md)。 创建新业务项目时可通过 `go-omni new --log-output file --storage local` 按需生成配置、装配代码与可运行示例，当前源码使用方式见 [CLI 文档](cmd/go-omni/README.md)。
|
||||
|
||||
应用配置可以统一从 `GO_OMNI_*` 环境变量加载，再交给 `omni.New`：
|
||||
|
||||
```go
|
||||
settings, err := omni.LoadConfig("")
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
logger, err := logx.New(settings.Log)
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
application := omni.New(omni.WithConfig(settings))
|
||||
application.OnShutdown(logger.Close)
|
||||
```
|
||||
|
||||
常用变量包括 `GO_OMNI_ENABLE_LOGGER`、`GO_OMNI_LOG_LEVEL`、
|
||||
`GO_OMNI_LOG_FORMAT`、`GO_OMNI_LOG_OUTPUT`、`GO_OMNI_SERVICE`、
|
||||
`GO_OMNI_ENVIRONMENT`、`GO_OMNI_HTTP_ADDR`、`GO_OMNI_SHUTDOWN_TIMEOUT` 和
|
||||
`GO_OMNI_TRUSTED_PROXIES`。可信代理变量使用逗号分隔的 IP/CIDR，例如
|
||||
`GO_OMNI_TRUSTED_PROXIES=127.0.0.1,10.0.0.0/8`；只有来自这些地址的连接才会解析
|
||||
`X-Forwarded-For`，默认只记录 socket 对端地址。数据库连接仍由
|
||||
`database.ConfigFromEnv` 从 `GO_OMNI_DB_*` 加载。
|
||||
|
||||
网络层也由同一份配置选择，Handler / Service / Repository 不需要导入具体适配器：
|
||||
|
||||
| 配置 | 默认值 / 用途 |
|
||||
| 接口来源或需求 | 配置位置 |
|
||||
| --- | --- |
|
||||
| `GO_OMNI_TRANSPORT` | `nethttp`；可选 `native`、`http2` |
|
||||
| `GO_OMNI_TLS_CERT_FILE` | TLS 证书 PEM 文件路径 |
|
||||
| `GO_OMNI_TLS_KEY_FILE` | TLS 私钥 PEM 文件路径，必须与证书一起配置 |
|
||||
| `GO_OMNI_SHUTDOWN_TIMEOUT` | `10s`，三种适配器共用的请求排空时间 |
|
||||
| `.api` 生成的接口 | `response Name (...)` 定义，`@server (response: Name)` 引用 |
|
||||
| 多个 `.api` 共用返回体 | 将声明放到 `common.api`，使用 `import "common.api"` |
|
||||
| 某个生成接口用另一种 JSON 公共体 | 路由声明 `@response OtherResponse` |
|
||||
| 只要业务 JSON、无成功包装 | 路由声明 `@response raw`；失败仍沿用组级格式 |
|
||||
| 手写路由和应用级 404/405 | `omni.WithResponse(response.Config{...})`，或读取配置后传入 `WithConfig` |
|
||||
| 成功和失败都要遵循特殊回调协议 | `HandleWithResponse` 绑定项目自己的 `response.Encoder` |
|
||||
| 单次直接输出 JSON、文本、XML、字节或空响应 | `c.JSON` / `c.Text` / `c.XML` / `c.Bytes` / `c.NoContent` |
|
||||
|
||||
例如运行自研 HTTP/1.1，或显式试用独立 HTTP/2 适配器：
|
||||
`${data}` 是业务返回值，`${message}` 是公开提示，`${code}` 是业务码；占位符保留原值类型，不是字符串拼接。还支持 `${requestId}`、`${ok}`、`${status}`，字段名和嵌套结构由项目决定。
|
||||
|
||||
```sh
|
||||
GO_OMNI_TRANSPORT=native go run ./examples/reference
|
||||
GO_OMNI_TRANSPORT=http2 GO_OMNI_HTTP_ADDR=127.0.0.1:8443 \
|
||||
GO_OMNI_TLS_CERT_FILE=./server.crt GO_OMNI_TLS_KEY_FILE=./server.key \
|
||||
go run ./examples/reference
|
||||
```
|
||||
- `codeType` 可以是 `string`、`int32`、`int64`；整数类型需要配置 `successCode` 和 `errorCode`。
|
||||
- `codes` 把逻辑错误码映射成对外业务码；未单独映射的失败使用 `errorCode`。JSON 业务码不会改变 HTTP 状态，例如 `404001` 仍对应 HTTP 404。
|
||||
- `successMessage` 设置成功提示；未设置 `errorMessage` 时沿用错误的公开提示。`messages` 可按逻辑错误码单独覆盖，优先级最高。全局 `errorMessage` 会替换未单独映射的所有失败提示，只有需要统一失败文案时才设置。
|
||||
- `dataMode: always` 在无数据时输出 null；默认 `omitNil` 省略模板里相应对象字段。没有 `returns` 的 `.api` 路由默认 HTTP 204、无响应体，这与 `200 + data:null` 是不同的接口契约。
|
||||
|
||||
`http2` 必须配置 TLS；native TLS 只协商 `http/1.1`，nethttp TLS 支持标准库的 HTTP/1.1 和 HTTP/2。
|
||||
未知适配器、缺少配对证书、无法加载证书时，`Run` / `RunContext` 在监听前返回错误并执行资源清理，不会退回其他协议。
|
||||
HTTP/2 仍为实验适配器，尚未合并到 native 多协议监听器。
|
||||
**生成接口的格式以 `.api` 为准**，修改后重新生成，运行时与 OpenAPI 一起更新；应用 YAML 不会覆盖它。404/405 没有匹配到某个 `.api` 接口，使用应用默认配置，需要统一时也配置应用默认值。
|
||||
|
||||
代码配置可写成 `omni.New(omni.WithTransport(omni.TransportNative), omni.WithTLS(certFile, keyFile))`。
|
||||
`ServeContext(ctx, listener)` 使用相同配置并接管已有 listener；失败或退出时也会关闭它。
|
||||
`RunWith(ctx, runner)` 保留自定义网络层入口，由 runner 自己管理 TLS、超时和网络参数；连接/请求上限等适配器专属选项仍通过这个入口设置。
|
||||
`NewServer` 仅创建标准库明文服务器，配置选择应用于 `Run`、`RunContext` 和 `ServeContext`。
|
||||
三种适配器的配置、真实 TLS 业务和关闭行为已通过 Linux 全量 race 及 10 次重复回归，见 [统一启动验收](performance/transportStartup.md)。
|
||||
文本/XML 回调用 Go 编码器或直接输出，`.api` 可用 `@handlerMode manual` 与 `@produces` 声明成功媒体类型；特殊错误协议仍需项目维护。`@response raw` 仅表示原始 JSON。前面示例的 `c.Text` 控制这次正常返回；需要连鉴权失败、业务错误和 panic 都按回调协议响应时使用 `HandleWithResponse`。完整配置和回调示例见 [响应参考](RESPONSE.md)。
|
||||
|
||||
`App` 同时实现标准 `http.Handler`。`Run` 监听 `SIGINT` / `SIGTERM`；`RunContext` 则由调用方的 context 控制退出，生成项目已使用 `signal.NotifyContext` 接好信号。
|
||||
退出时先停止接收新请求，等待活跃请求完成，再执行资源清理。超过 `ShutdownTimeout` 时强制关闭连接、取消请求 context，并返回超时错误。业务代码应响应 context 取消；框架无法强制结束忽略取消的业务 goroutine。数据库连接池由 `database.Open` 创建，在服务退出时调用 `Close`。
|
||||
## 业务开发与依赖装配
|
||||
|
||||
应用资源可以直接挂到 `omni.New` 返回的生命周期上：
|
||||
### 日志
|
||||
|
||||
业务包直接使用 `logx`，不需要 HTTP 框架对象：
|
||||
|
||||
```go
|
||||
application := omni.New()
|
||||
application.OnShutdown(db.Close)
|
||||
// ctx 是 Service 接收的标准 context.Context。
|
||||
logx.InfoContext(ctx, "order.created", "orderId", orderID)
|
||||
logx.ErrorContext(ctx, "order.failed", "error", err)
|
||||
```
|
||||
|
||||
清理函数会按注册顺序的逆序执行，`application.Close()` 和 `RunContext` 都会触发，且重复调用安全。
|
||||
入口用 `logx.Setup` 初始化，退出时关闭；生成的 API 项目已经完成日志初始化和退出清理。Service、Repository 和外部请求持续传递请求的 `context.Context`，业务日志可关联 `requestId`，同时保留取消信号。框架不规定或自动注入 `userId`、`tenantId`。
|
||||
|
||||
服务可以把数据库、缓存等依赖注册为就绪探针：
|
||||
`WithLogger(true)` 开启 HTTP 访问日志。格式、级别、文件轮转、脱敏键和慢请求阈值均可配置，见 [日志](logx/README.md)。
|
||||
|
||||
### 鉴权与业务错误
|
||||
|
||||
`.api` 可声明认证方式和关联中间件，例如把下面的声明放入契约，并在相应 `@server` 块中加上 `auth: UserAuth`：
|
||||
|
||||
```text
|
||||
auth UserAuth (
|
||||
type: bearer
|
||||
middleware: Auth
|
||||
)
|
||||
```
|
||||
|
||||
生成器会创建 `internal/middleware/auth.go`，由项目实现凭据校验和身份注入。声明会生成路由绑定与 OpenAPI 的认证描述，**不会自动实现登录或授权规则**；未实现的 hook 返回 501。手写路由可使用 `auth.RequireAuth(authenticator)` 或自己的中间件。JWT、Session 和 Policy 按需选择。
|
||||
|
||||
业务错误可以集中定义，业务只选择发生了哪个错误。**HTTP 状态由项目配置，业务失败可以返回 HTTP 200**；框架不根据 HTTP 状态单独判断成功与否。
|
||||
|
||||
错误目录支持两种维护方式，按项目选择一种：**Go 中定义并用 `omni.WithErrors` 注册一次**，或者在公共 `.api` 中声明并生成调用函数。前者不要求 `.api` 重复声明目录或逐路由列出错误；生成路由默认继承 App 目录。
|
||||
|
||||
采用 `.api` 管理时，其他契约可通过 `import` 引用：
|
||||
|
||||
```text
|
||||
errorCatalog CommonErrors (
|
||||
defaultStatus: 200
|
||||
errors: {
|
||||
"UsernameInvalid": {"key": "USERNAME_INVALID", "code": 400002, "message": "用户名格式不正确"},
|
||||
"PasswordInvalid": {"key": "PASSWORD_INVALID", "code": 400002, "message": "密码格式不正确"},
|
||||
"PermissionDenied": {"key": "PERMISSION_DENIED", "status": 403, "code": 403001, "message": "没有权限"}
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
`UsernameInvalid` 是生成函数名；`key` 是唯一逻辑标识；`code` 是项目对外的字符串或整数业务码，可以重复。条目没有填写 `status` 时使用目录的 `defaultStatus`，未配置目录默认值时为 400。这个默认值只作用于该目录的条目，不会把所有框架异常都改成 200。
|
||||
|
||||
在已有公共响应中保留 `codeType: int32` / `int64` / `string`、成功码、未定义错误的兜底码和返回体模板；不再重复填写这几条错误的 `codes` / `messages`。通过 `@server (errors: UsernameInvalid, PasswordInvalid)` 或路由 `@errors UsernameInvalid` 引用它们。
|
||||
|
||||
生成后业务调用：
|
||||
|
||||
```go
|
||||
checker, err := health.New(health.Probe{
|
||||
Name: "database",
|
||||
Check: db.PingContext,
|
||||
})
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
return TokenResponse{}, apierrors.UsernameInvalid()
|
||||
// 需要保留内部原因时：
|
||||
return TokenResponse{}, apierrors.UsernameInvalid().WithCause(err)
|
||||
```
|
||||
|
||||
生成器同时提供 `internal/apierrors.Catalog()`、错误函数、路由错误目录及 OpenAPI。目录会在 App 中间件执行前绑定到生成路由；无需手动改已经生成的 main。HTTP 200 的错误使用失败响应模板；OpenAPI 用 `anyOf` 同时保留成功 DTO 和错误体，多条错误共用数字码时仍保留各自示例。完整契约见 [errors.api](examples/contracts/errors.api)。
|
||||
|
||||
手写项目可在启动时加载自己的目录，保留原来的响应配置：
|
||||
|
||||
```go
|
||||
// omnierrors 是 git.yuntuo.hk/k2safe/go-omni/errors。
|
||||
catalog := omnierrors.Catalog{
|
||||
DefaultStatus: 200,
|
||||
Definitions: map[string]omnierrors.Definition{
|
||||
"USERNAME_INVALID": {Code: 400002, Message: "用户名格式不正确"},
|
||||
"PASSWORD_INVALID": {Code: 400002, Message: "密码格式不正确"},
|
||||
},
|
||||
}
|
||||
application.GET("/health/live", checker.LivenessHandler())
|
||||
application.GET("/health/ready", checker.ReadinessHandler())
|
||||
app := omni.New(
|
||||
omni.WithErrors(catalog),
|
||||
omni.WithResponse(response.Config{
|
||||
CodeType: "int32", SuccessCode: 0, ErrorCode: 9999,
|
||||
MessageField: "msg", DataMode: "always",
|
||||
}),
|
||||
)
|
||||
// Service 只返回标准 error，不依赖 App 或 HTTP Context：
|
||||
// return omnierrors.ByCode("USERNAME_INVALID").WithCause(err)
|
||||
```
|
||||
|
||||
存活检查只确认进程在线；就绪检查会执行全部探针，任意依赖失败时返回 HTTP 503。
|
||||
目录也可放入 `config.Config.Errors`，由 JSON/YAML 加载；生成项目的路径为 `server.errors`，生成路由只有显式引用错误定义时才使用 `.api` 独立目录，未声明则继承 App。不同 App 独立持有配置，单路由也可通过 `response.WithErrors` 绑定专用目录与自定义 Encoder。直接输出文本、XML、下载或已提交的响应继续保留原协议。
|
||||
|
||||
新项目脚手架会生成项目自己的 `internal/servicecontext`。它集中保存 Logger、数据库、缓存和外部客户端，Service 只依赖这个项目上下文，不把基础设施初始化散落到各个 Handler：
|
||||
访问日志保留实际 HTTP 状态，并增加失败标记、逻辑错误标识和目录业务码；指标、链路及框架标准中间件/幂等重放也保留失败语义。未知标识使用系统错误兜底，内部 cause 不写入默认公开响应。旧 `error (...)`、`New` / `BadRequest` / `Codes` / `Messages` 继续支持；新目录与旧映射冲突会报错，避免静默覆盖。
|
||||
|
||||
动态提示也可以集中配置，在目录中声明 `message: "{label}不能超过{max}个字符"` 和有序 `params`（label/string、max/int），生成带类型的调用：
|
||||
|
||||
```go
|
||||
services, err := servicecontext.New(ctx, logger)
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
defer services.Close()
|
||||
userService := service.NewUsers(services)
|
||||
return apierrors.TextTooLong("企业名称", 100)
|
||||
// 最终提示：企业名称不能超过100个字符
|
||||
```
|
||||
|
||||
## 完整业务参考项目
|
||||
运行时支持 `omnierrors.ByCode("TEXT_TOO_LONG").WithParams(...)`，与生成函数共用解析器。固定错误继续无参数调用；缺参或类型错误使用系统兜底。模板、参数类型及具体响应示例同步写入 OpenAPI。完整示例见 [errorParams.api](examples/contracts/errorParams.api)。
|
||||
|
||||
[`examples/reference`](examples/reference/README.md) 提供按 Handler / Service / Repository / Model 分层的用户 CRUD 示例。默认使用并发安全的内存存储，支持分页、邮箱唯一校验、结构化请求日志和统一错误，无需配置数据库。
|
||||
更详细的配置、作用域和升级步骤见 [统一错误目录](errors/README.md)。
|
||||
|
||||
从远程版本生成并升级一个独立业务模块，可运行：
|
||||
### 数据库、存储及其他模块
|
||||
|
||||
生成项目在 `internal/svc` 中创建依赖，提供给 Logic/Repository，并用 `c.OnClose(db.Close)` 登记自有资源。生成的 main 在 HTTP 排空后关闭 svc，再关闭日志。直接使用框架的手写项目则可以用 `app.OnShutdown(db.Close)`；不要对同一资源重复登记。
|
||||
|
||||
已有项目使用 `driver.Connector` 时，直接 `database.OpenConnector(ctx, connector, database.DefaultPoolConfig())`。MySQL 等驱动的独立 TLS、Logger、时区与拨号参数由项目构造 Connector；框架负责连接池、启动 Ping、健康检查及事务。无需转成 DSN，也无需注册全局 TLS/Logger。具体示例和资源归属见 [Connector 接入](database/README.md#connector-接入v091-preview)。
|
||||
|
||||
| 能力 | 包与接入说明 |
|
||||
| --- | --- |
|
||||
| 数据库连接池、事务、显式迁移 | `database`，见 [数据库](database/README.md)；表结构与驱动由项目选择 |
|
||||
| 本地文件、S3、R2、OSS、直传与临时下载 | `storage`，见 [文件存储](storage/README.md)；业务依赖接口，装配时选择适配器 |
|
||||
| 缓存、出站 HTTP、限流、幂等、后台任务 | `cache`、`httpc`、`middleware`、`task`，见 [基础模块](MODULES.md) |
|
||||
| JWT/Session、策略、Redis 队列、审计、分页、观测 | 见 [扩展模块](ADVANCED.md)；按需注入实现 |
|
||||
| 存活与就绪检查 | `health`，见 [健康检查](health/README.md)；数据库等依赖作为 readiness 探针 |
|
||||
|
||||
API 项目的数据库迁移需要单独维护并显式执行；启动不会自动改表。完整示例 [userService](examples/userService/README.md) 展示 MySQL、事务、鉴权、日志和文件导出，可参考依赖装配方式后接入自己的业务规则。
|
||||
|
||||
## 配置与运行
|
||||
|
||||
生成项目从 `etc/config.yaml` 读取配置，优先级为 **默认值 → 配置文件 → 环境变量**。密钥通过环境变量提供。手写入口需显式调用配置加载函数并传给 `omni.New(omni.WithConfig(settings))`；单独调用 `omni.New()` 不会自动读取环境变量。
|
||||
|
||||
| 环境变量 | 用途 |
|
||||
| --- | --- |
|
||||
| `GO_OMNI_HTTP_ADDR` | 监听地址；生成项目默认 `127.0.0.1:8080` |
|
||||
| `GO_OMNI_TRANSPORT` | `nethttp`（默认）、`native`、`http2` |
|
||||
| `GO_OMNI_TLS_CERT_FILE` / `GO_OMNI_TLS_KEY_FILE` | 成对设置 TLS 证书和私钥路径 |
|
||||
| `GO_OMNI_HTTP_READ_HEADER_TIMEOUT` / `GO_OMNI_HTTP_READ_TIMEOUT` | 请求头 / 请求读取超时，如 `5s` / `30s` |
|
||||
| `GO_OMNI_HTTP_WRITE_TIMEOUT` / `GO_OMNI_HTTP_IDLE_TIMEOUT` | 响应写入 / Keep-Alive 空闲超时 |
|
||||
| `GO_OMNI_HTTP_MAX_HEADER_BYTES` | 请求头大小限制，字节数 |
|
||||
| `GO_OMNI_SHUTDOWN_TIMEOUT` | 优雅退出等待时间，默认 `10s` |
|
||||
| `GO_OMNI_ENABLE_LOGGER` / `GO_OMNI_LOG_LEVEL` | 访问日志开关、日志级别 |
|
||||
| `GO_OMNI_TRUSTED_PROXIES` | 可解析转发地址头的可信代理 IP/CIDR，逗号分隔 |
|
||||
| `GO_OMNI_DB_DSN` | 选择 MySQL 初始化时的数据库连接配置 |
|
||||
|
||||
例如在生成项目中切换 native：
|
||||
|
||||
```sh
|
||||
python3 scripts/verifyBusiness.py --version v0.6.0-preview
|
||||
GO_OMNI_TRANSPORT=native go run .
|
||||
```
|
||||
|
||||
该验收会在临时目录中先固定 `v0.2.0`，再升级到 `v0.6.0-preview`，检查无本地 replace、配置加载、结构化日志、requestId、CRUD、校验错误、业务错误和优雅退出。
|
||||
手写入口可用 `omni.WithTransport(omni.TransportNative)`；TLS 配置为 `omni.WithTLS(certFile, keyFile)`。native 提供 HTTP/1.1、Keep-Alive、TLS、超时、连接/请求并发上限和对象复用；HTTP/2 是单独的实验适配器，必须配置 TLS。默认 nethttp 的 TLS 支持 HTTP/1.1 与 HTTP/2。
|
||||
|
||||
标准库与 native 的并发、延迟和长连接内存对照见 [PERFORMANCE.md](PERFORMANCE.md)。`python3 scripts/verifyPerformance.py` 运行检查与 benchmark；增加 `--load --output /tmp/goOmniPerf.json` 可测量独立服务进程并保存报告。
|
||||
读写超时也可以在生成项目的 `etc/config.yaml` 中声明（放在 `server.http` 下）：
|
||||
|
||||
HTTP/2 仍是显式 opt-in 实验适配器，不会改变 native 的 HTTP/1.1 默认路径。Linux TLS 长测使用 `python3 scripts/verifyHTTP2.py --duration 30m`，默认使用普通 Go 运行模式；`--race` 默认改为 60 秒，用于并发检查，其额外内存开销不能当成生产运行基线。
|
||||
```yaml
|
||||
server:
|
||||
http:
|
||||
readHeaderTimeout: 5s
|
||||
readTimeout: 30s
|
||||
writeTimeout: 30s
|
||||
idleTimeout: 60s
|
||||
maxHeaderBytes: 1048576
|
||||
```
|
||||
|
||||
多连接混合场景使用 `python3 scripts/verifyHTTP2.py --scenario mixed --duration 30m`：8 条独立 TLS 连接，每条连接 14 个普通请求 worker、1 个慢上传 worker、1 个慢下载 worker，共 128 个 worker。上传为 256 KiB、每 4 KiB 等待 2 ms；下载为 8 MiB、每次最多读取 64 KiB 后等待 20 ms。日志分别记录三类成功数、传输字节数、每条连接的覆盖情况，以及停止并释放测试数据后两次 GC 的采样。
|
||||
代码配置使用 `omni.WithHTTPConfig(omni.HTTPConfig{ReadTimeout: 30*time.Second, WriteTimeout: 30*time.Second})`。`Run`、`RunContext`、`ServeContext` 会应用它；`NewServer` 会配置返回的标准 `http.Server`，包含可选的 Go 字段 `ErrorLog`。**正值覆盖、零值保留所选网络层的原有默认行为、负值报错**；不配置时升级行为不变。超时含义与支持范围见 [HTTP 配置](transport/README.md#http-配置v091-preview)，不要把网络 I/O 超时当成业务执行时限。
|
||||
|
||||
该脚本默认把测试容器限制为 2 核、2 GiB 内存（禁用 swap）、256 个进程/线程，整个命令最多运行 40 分钟，中断和超时会清理本次容器。这些限制可用 `--cpus`、`--memory-mb`、`--pids-limit`、`--wall-timeout` 调整；共享服务器应先用 `--duration 60s` 短测，再逐步延长。每 15 秒输出的堆、RSS 和 FD 统计包含同一进程内的客户端与服务端。
|
||||
自研网络层通过 `RunWith(ctx, runner)` 接入监听与连接生命周期，通过 `NewWithRouter(router)` 替换路由；业务 Handler/Service 不需要导入具体适配器。细节与验收契约见 [网络适配层](transport/README.md)。
|
||||
|
||||
Linux amd64 已完成 30 分钟、单 TLS 连接、128 个 worker 的普通模式长测：58,102,476 次请求，0 失败、0 协议错误，采样 RSS 峰值约 22.6 MiB，连接/活动请求归零且 FD 回到基线。完整采样和原始日志见 [HTTP/2 长测报告](performance/http2SoakLinux.json) 与 [原始日志](performance/http2SoakLinux.txt)，此前的 race 对照见 [短测记录](performance/http2SmokeLinux.json)。这项结果覆盖单连接复用。
|
||||
生成项目的依赖可调用 `svcCtx.RequestShutdown(err)` 主动申请退出，框架排空请求、清理依赖后保留故障原因并以非零状态退出。健康检查与 OpenAPI 的开关、路径通过 `server.endpoints` 配置，健康响应默认沿用项目公共体；未就绪保持 HTTP 503。完整配置和 v0.12 项目的升级步骤见 [项目指南](PROJECT.md#依赖主动申请退出)。
|
||||
|
||||
多连接慢客户端场景也已完成 Linux amd64 的 30 分钟长测：8 条 TLS 连接、128 个 worker，53,079,128 次普通请求、106,971 次慢上传、5,588 次慢下载，共 53,191,687 次，0 失败与协议错误。采样 RSS 峰值约 116.6 MiB（包含客户端、服务端和下载缓冲）；退出后连接/请求归零，goroutine 回到 2、FD 回到 6；释放测试数据并两次 GC 后存活堆约 450 KiB，RSS 不要求立即归还操作系统。完整 120 份采样见 [混合长测报告](performance/http2MixedSoakLinux.json) 和 [原始日志](performance/http2MixedSoakLinux.txt)。连接级窗口耗尽、WINDOW_UPDATE 恢复及零窗口写阻塞的关闭回收也已有独立测试；Nginx 的 HTTP/2 回源验收结果见下方，适配器保持实验状态。
|
||||
`Run` 处理 SIGINT/SIGTERM；`RunContext` 接收调用方控制的退出信号。服务先停止接收新请求，等待活跃请求完成，再清理资源；超时会取消请求并关闭连接，业务代码仍需响应 context 取消。
|
||||
|
||||
`python3 scripts/verifyHTTP2Proxy.py --count 3` 验证真实 Nginx 双段 TLS/h2、回源连接复用、证书拒绝、超时/取消恢复与新旧实例的 GOAWAY 排空；增加 `--race` 可运行并发检查。Linux amd64、Nginx 1.30.5 的普通与 race 模式各 3 轮均已通过。编译和测试容器顺序运行，均限制为 2 核、2 GiB；测试容器禁用外部网络，全部请求在容器内完成。使用方法、报告及当前边界见 [HTTP/2 代理回源验收](transport/http2/PROXY.md)。
|
||||
## 日常开发与升级
|
||||
|
||||
在框架根目录运行：
|
||||
在已生成的 API 项目目录执行：
|
||||
|
||||
```sh
|
||||
go run ./examples/reference
|
||||
go-omni api validate
|
||||
go-omni api inspect
|
||||
go-omni api generate --dry-run
|
||||
go-omni api generate
|
||||
go-omni api generate --check
|
||||
go test ./...
|
||||
```
|
||||
|
||||
默认地址为 `http://127.0.0.1:8080`。示例文档提供完整的 curl 操作流程。数据只保存在内存中，重启后清空。
|
||||
`main.go`、`Gen.go`、`docs/openapi.json` 和 manifest 由生成器管理，手动修改会报告冲突。Logic、Repository、中间件实现、配置和依赖装配属于项目，重复生成保留手写内容。契约变化会提示受影响的 Logic 文件和 DTO 字段，明确的签名错误会给出原签名与期望签名；生成后 `--check` 仍能检出未修复的问题。将 `.api`、生成文件和 `.goOmni/apiManifest.json` 一起提交，CI 同时运行 `generate --check` 与 `go test ./...`。详见 [契约变更提示与检查边界](PROJECT.md#契约变更提示)。
|
||||
|
||||
框架的 `App` 也实现了标准 `http.Handler`，可以直接用于 `http.Server` 和 `httptest.NewServer`；业务路由可通过 `*omni.RouterGroup` 注册，无需导入网络库。
|
||||
CLI 与业务 module 固定使用 `v0.13.0-preview`。新布局不兼容旧 manifest；旧试验项目需在新目录生成并搬入业务文件，不能直接覆盖手写入口。新布局内部升级再执行上述生成与测试步骤，手写框架项目只需依赖升级及业务回归。版本变化、迁移边界和验收记录见 [发布说明](RELEASE.md)。
|
||||
|
||||
## 当前边界
|
||||
## 按需深入
|
||||
|
||||
缓存、Redis 消息队列和进程内定时任务已作为可选模块提供。认证层提供 `Authenticator`、JWT/Session 适配器和 Policy 接口，登录流程与业务授权规则由项目实现。核心数据库层只依赖 `database/sql`，具体驱动、迁移和表结构由项目选择。

这一版完善接口开发体验：业务错误和鉴权可在 .api 中声明，代码调用与 OpenAPI 同步；增加路由总览、文档导出和无写入的生成预览。
|
||||
预览版用于固定版本试用；API 方言有明确范围，HTTP/2 仍是独立实验适配器。

本版补齐项目依赖主动退出与内置接口配置。ID 租约、数据库或后台任务等故障由项目判断，框架通过统一生命周期完成退出；不内置业务规则。
|

|

## 安装与开始
|
||||
## 使用与升级
|
||||
|
||||
```sh
|
||||
GOPRIVATE=git.yuntuo.hk go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.7.0-preview.1
|
||||
|
||||
go-omni api new --module example.com/demo ./demo
|
||||
cd demo
|
||||
GOPRIVATE=git.yuntuo.hk go mod tidy
|
||||
go run ./cmd/server
|
||||
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.13.0-preview
|
||||
# 在业务 module 中执行
|
||||
go get git.yuntuo.hk/k2safe/go-omni@v0.13.0-preview
|
||||
go-omni api generate
|
||||
```
|
||||
|
||||
需要该 Git 仓库的读取权限时，通过自己的 Git 凭据管理器配置；不要将凭据写入 module path 或 go.mod。
|
||||
CLI 会将自身下载版本固定到生成项目的 go.mod。业务项目正常使用远程模块，不需要本地 replace。
|
||||
新项目自动获得全部扩展。v0.12 的 config/svc 属于项目文件，重新生成会保留它们；需按 [升级步骤](PROJECT.md#从-v012-生成项目升级) 给 svc 补入 Lifecycle、RequestShutdown 与清理衔接，main 和 Handler 由生成器更新。旧 v0.11 目录仍按原迁移规则在新目录生成。
|
||||
|
||||
使用已有定义，并一次选择基础模块：
|
||||
## 行为
|
||||
|
||||
- `svc.RequestShutdown(err)` 非阻塞通知：停止接收请求、排空、关闭依赖和日志。首个非空故障保留，故障退出码为 1；正常停止在没有其他故障时退出码为 0。初始化期间通知、并发通知和排空期间报告故障均可处理。
|
||||
- App 生命周期入口保留异常 context 取消原因；符合 context.Canceled 的信号取消保持正常停止。生成入口还读取 Controller.Err，保留显式依赖故障，即使该故障包装了 context.Canceled。
|
||||
- `/health/ready` 修复绕过响应配置的问题，默认与 liveness 一起使用项目 App 的响应格式。就绪成功使用项目成功码与提示；未就绪使用 `NOT_READY` 的项目错误定义，同时固定 HTTP 503。raw 模式只返回健康数据；内部探针原因仅供日志。
|
||||
- `server.endpoints` 控制三个内置 GET 接口的开关和路径，健康端点另有 responseMode。支持环境变量覆盖。OpenAPI 保持原始规范，不包业务公共体；关闭 HTTP 端点不影响生成文档。
|
||||
- `.api` 不再固定保留三个默认路径；启用的内置路径与业务 GET/参数/通配路由重叠时，启动前返回明确错误并清理已创建的依赖。关闭或改名后允许项目接管旧路径。全局中间件继续执行。
|
||||
|
||||
## 验收
|
||||
|
||||
源码测试和实际生成项目验证记录见 [生命周期与端点验收](performance/lifecycleEndpointsAcceptance.md)。复验命令：
|
||||
|
||||
```sh
|
||||
go-omni new --api user.api --module example.com/userService \
|
||||
--database mysql --storage local --log-output file ./userService
|
||||
```
|
||||
|
||||
MySQL 与存储需要按生成 README 设置环境变量。任意契约生成的业务方法先返回 501，
|
||||
由业务方实现；可直接参考 [完整用户示例](examples/userService/README.md)。
|
||||
|
||||
## 主要变化

- `error (...)` + `@errors` 声明业务错误，生成 `apierrors.EmailTaken()` 等全新实例构造函数和错误码常量。
|
||||
- `auth Name (...)` + `@auth` 同步 OpenAPI security 与实际路由中间件，声明本身不替代凭证验证。
|
||||
- 多行 `@doc` 支持 description/tags/deprecated；一个状态可有多个业务错误示例。
|
||||
- 项目内直接 `api inspect`、`api export`、`api generate --dry-run`，无需重复指定入口文件。
|
||||
|
||||
此前 v0.7.0-preview 已提供：
|
||||
|
||||
- `.api` 生成项目、绑定/校验、路由、业务骨架和 OpenAPI；支持分组、导入、命名中间件。
|
||||
- 同一入口初始化 MySQL、日志、Local / S3 / R2 / OSS；标准 context 与 httpx 保持业务/网络分离。
|
||||
- 生成器保护手写业务文件，校验自有文件哈希，支持只读 --check；基础设施选项持久化到 manifest。
|
||||
- 完整用户示例包含数据库迁移、CRUD / 分页、事务审计、鉴权、文件导出与 requestId 日志。
|
||||
- 日志文件轮转/结构化脱敏、上传策略/直传/分片，以及此前 main 分支的通用业务模块一并提供。
|
||||
|
||||
所有变化及网络层验收记录见 [CHANGELOG](CHANGELOG.md)。
|
||||
|
||||
## 升级注意
|
||||
|
||||
1. 将 CLI 和项目框架依赖固定为相同版本。旧版 CRUD 项目继续使用现有目录；不能直接用 API 生成器接管已有 Go 目录。
|
||||
2. Gen.go 由生成器维护，业务实现/配置/迁移由项目维护。新增 API 后执行 generate 和 go test；修改或删除类型需要同步处理自己的业务代码。
|
||||
3. `.goOmni/apiManifest.json` 需随代码提交。切换数据库或存储选项时，在新目录生成对照后迁移；重新生成不会改写现有基础设施文件。
|
||||
4. 配置使用 lowerCamelCase。DSN、Token、存储密钥由环境变量提供；`database.Config` 的 DSN 不会被 JSON/YAML 序列化。
|
||||
5. 旧 `.api` 仍可解析。新语法需要本版 CLI；生成的错误函数沿用已有框架错误类型。旧 CLI 无法解析新增声明，请一起升级。鉴权引用的已有 hook 和业务函数仍保留，不会自动重写。
|
||||
6. API 的 none/memory 数据库选项仅表示不打开连接，不会从 HTTP DTO 自动推导内存仓库或数据表。
|
||||
|
||||

|
||||
远程验收在发布后执行，报告单独提交，不改写发布标签。此版仍为 preview；具体业务的租约失效保护、鉴权与事务回归由接入项目验证。资源清理顺序不代表能强行结束忽略 context 取消的业务 goroutine；项目 Close 必须停止并等待自己启动的后台任务。
|
||||
|
||||
OSS/R2 云端仍需项目自己的账号做上线环境验收；当前云端适配器检查不等同于这些账号的实网测试。

# v0.12.0-preview（历史版本）
|
||||
|
||||
本版用于固定版本开展业务接入。生成器统一维护服务根目录 main.go、路由、HTTP Handler、DTO 和 OpenAPI，业务方维护 `.api`、config、svc、logic、repository 与项目中间件。目录不再生成 cmd/server、settings、servicecontext 或 service。
|
||||
|
||||
## 安装与接入
|
||||
|
||||
仓库权限及 PATH 配置见 [README](README.md#准备环境与安装)。CLI 与框架使用同一版本：
|
||||
|
||||
```sh
|
||||
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.12.0-preview
|
||||
go-omni new --module example.com/hello ./hello
|
||||
cd hello
|
||||
go mod tidy
|
||||
go run .
|
||||
```
|
||||
|
||||
已存在的手写项目可直接 `go get git.yuntuo.hk/k2safe/go-omni@v0.12.0-preview`。采用生成目录的旧项目在新目录生成后迁入业务代码，详见 [接入步骤](PROJECT.md#已有服务接入步骤) 和 [文件维护边界](PROJECT.md#哪些文件由用户维护)。新 manifest v2 不兼容旧 manifest；不会静默覆盖手写 main，也不会删除独立 cmd/migrate 等工具。
|
||||
|
||||
## 本版行为
|
||||
|
||||
- 根目录支持 go run / go build；入口负责配置、日志、依赖、HTTP 启动与信号退出。svc 的 AppOptions、GlobalMiddleware 和 OnClose 是显式扩展入口；初始化/监听失败会释放资源，正常退出先排空请求再关闭依赖和日志。
|
||||
- `.api` 入口通过 `@app(defaultResponse: Name)` 选择默认响应，覆盖普通路由、404/405 与相应中间件错误；多模板不会按声明顺序猜默认值。字段、状态、业务码和文案由项目配置。
|
||||
- 保持 v0.11.1 的错误目录继承：Go 中注册一次，无独立错误目录的生成路由继承 App。带参数提示、内部错误链、raw 响应和独立目录保持各自行为。
|
||||
- raw/multipart 上传及 `@produces` 下载可直接编写 Logic，由生成 Handler 完成受限读取、响应和流关闭。损坏 multipart 默认 400，超限 413；项目可以定制公开错误。
|
||||
- 契约变更提示受影响的 Logic、DTO 字段和请求模式；明确的签名/语法/重复方法错误使 `generate --check` 失败。重新生成保留业务文件，main 和其他生成文件的漂移也会被检查。
|
||||
|
||||
## 验收与范围
|
||||
|
||||
发布前全量 race 测试、go vet、go build 和本地实际生成项目进程验收通过。发布后的空缓存远程验收也已通过，记录见 [生成项目验收](performance/managedProjectAcceptance.md) 和 [远程产物报告](performance/managedProjectRemote.json)。报告作为单独提交保存，v0.12.0-preview 标签保持在发布代码提交 `158b8002b355f09237cd12f49d9b66ee78d493f3`，没有改写。复验命令：
|
||||
|
||||
```sh
|
||||
GO_OMNI_SCAFFOLD_INTEGRATION=1 go test -race -p=1 -count=1 -timeout=300s ./...
|
||||
go vet ./...
|
||||
go build ./...
|
||||
python3 scripts/verifyManagedProject.py
|
||||
python3 scripts/verifyManagedRelease.py --version v0.12.0-preview
|
||||
```
|
||||
|
||||
远程验收使用空 module 缓存安装已发布 CLI，生成的业务项目仅依赖同版远程 module，无本地 replace；检查根目录运行/构建、重新生成、错误继承/模板参数、上传下载、nethttp/native 的真实请求与退出信号，以及初始化失败/监听失败/请求排空后的清理。
|
||||
|
||||
本版不代表具体业务项目已完成迁移验收。HTTP/2 仍为实验状态；真实数据库、云账号和业务服务器不属于本轮验收范围。轻量 Logic 检查不能代替 Go 编译器或业务测试。静态 OpenAPI 不执行 Go 代码，因此不会自动列举仅在 Go 中维护的错误目录。请求流校验不能回滚业务提前执行的副作用，关键写入应放在 `body.Complete()` 成功之后。
|
||||
|
||||
---
|
||||
|
||||
# v0.11.1-preview（历史版本）
|
||||
|
||||
修复生成路由使用空错误目录遮蔽 `omni.WithErrors(catalog)` 的问题。错误现在可以只在 Go 中注册一次，`.api` 无需重复定义错误目录或逐条列出错误。
|
||||
|
||||
## 行为
|
||||
|
||||
- 未声明路由错误列表：继承 App 目录，包括带参数提示及项目自定义 INTERNAL_ERROR 兜底。
|
||||
- 显式引用路由错误：继续使用路由独立目录，不与 App 合并。
|
||||
- `@errors none` 清空 `.api` 分组错误列表，随后继承 App。
|
||||
- 错误继承不覆盖 `.api` 的返回格式、RawJSON、手写绑定或请求体限额；全局中间件提前返回、标准桥接与克隆保持一致。
|
||||
- 空 `response.WithErrors` / `MustWithErrors` 返回原 Encoder，既不覆盖 Context 的目录，也不在编码阶段按空目录重新解析错误。
|
||||
|
||||
## 升级
|
||||
|
||||
```sh
|
||||
go get git.yuntuo.hk/k2safe/go-omni@v0.11.1-preview
|
||||
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.11.1-preview
|
||||
go-omni api generate --dry-run
|
||||
go-omni api generate
|
||||
go test ./...
|
||||
```
|
||||
|
||||
运行时修复也适用于旧 v0.11.0 生成代码，因此升级运行时后即可解除空目录遮蔽。同步升级 CLI 重新生成时不再创建空目录包装；已生成业务文件继续受保护。代码生成最低运行时仍为 v0.11.0-preview。
|
||||
|
||||
接入见 [README](README.md)、[错误目录继承](errors/README.md) 和 [只在 Go 注册错误的契约示例](examples/contracts/errorInheritance.api)。静态 OpenAPI 不执行 Go 配置，保留契约响应结构，不自动列举运行时目录内容。
|
||||
|
||||
## 验收
|
||||
|
||||
复现用例在修复前：普通路由通过，生成/RawJSON 路由和提前返回中间件共 12 项失败，均变成 500/英文系统提示。修复后同一批用例通过。
|
||||
|
||||
```sh
|
||||
GO_OMNI_SCAFFOLD_INTEGRATION=1 go test -race -p=1 -count=1 -timeout=300s ./...
|

go vet ./...

|
||||
```
|

# 公共响应体与独立接口协议
|
||||
|
||||
这些功能从 `v0.8.0-preview` 提供。CLI 与项目框架依赖请固定到同一版本；源码开发可显式使用 `--framework-dir`。`v0.7.0-preview.1` 不包含响应模板声明。
|
||||
|
||||
go-omni 的响应编码由应用或接口配置。没有配置时保留旧版默认值；业务可以定义自己的字段、嵌套结构、错误码类型、提示和空值行为。`response.Response` 仅保留为兼容 DTO，运行时与生成器不再通过它固定响应结构。
|
||||
|
||||
## 在 .api 中定义一次、到处引用
|
||||
|
||||
```go
|
||||
response CommonResponse (
|
||||
body: {
|
||||
"code": "${code}",
|
||||
"msg": "${message}",
|
||||
"data": "${data}"
|
||||
}
|
||||
codeType: int32
|
||||
successCode: 200
|
||||
errorCode: 9999
|
||||
successMessage: "操作成功"
|
||||
dataMode: always
|
||||
codes: {"USER_NOT_FOUND":404001}
|
||||
messages: {"USER_NOT_FOUND":"用户不存在"}
|
||||
)
|
||||
|
||||
@server (
|
||||
group: user
|
||||
response: CommonResponse
|
||||
)
|
||||
service user-api {
|
||||
@handler getUser
|
||||
get /users/:userId (GetUserReq) returns (UserResp)
|
||||
|
||||
@response raw
|
||||
@handler rawUser
|
||||
get /rawUsers/:userId (GetUserReq) returns (UserResp)
|
||||
}
|
||||
```
|
||||
|
||||
请求/业务返回类型照常在 `type` 中定义。上例 `UserResp` 是业务数据，由模板中的 `${data}` 放入公共体。请求失败时，同一模板输出映射后的业务错误。错误本身的 HTTP 状态保持不变，业务 `code` 与 HTTP 状态相互独立。
|
||||
|
||||
- 公共声明可以放进 `common.api`，其他契约通过 `import "common.api"` 复用。
|
||||
- `@server (response: CommonResponse)` 指定整个 service 块的公共体；不同块可以引用同一个模板。
|
||||
- `@response PartnerResponse` 为单接口替换模板，成功和错误一起生效。
|
||||
- `@response raw` 让成功 JSON 直接返回业务对象，错误沿用组级模板；组本身为 raw 时，错误使用默认模板。
|
||||
- 模板名使用 UpperCamelCase；未知模板、未知配置、错误的占位符和冲突设置在生成前报错。
|
||||
|
||||
**生成接口以 `.api` 为响应契约来源。** 生成器把选定模板编译进 `internal/handler/responseGen.go`，在全局鉴权、限流等应用中间件之前选定，然后再执行路由中间件和业务。OpenAPI 与运行时共用配置和映射规则。即使 `.api` 没有声明模板，生成接口也明确使用默认契约，不会被应用的 YAML 设置静默改变。
|
||||
|
||||
业务只需返回业务数据或业务错误，无需每个 Handler 手工组装公共体。生成器维护模板、路由及文档文件，重复生成不覆盖手写 Service、Repository、middleware 和配置。
|
||||
|
||||
## 自定义结构与占位符
|
||||
|
||||
公共体没有规定必须出现的字段，也可以把成功和失败分开：
|
||||
|
||||
```go
|
||||
response PartnerResponse (
|
||||
body: {
|
||||
"accepted": "${ok}",
|
||||
"payload": "${data}",
|
||||
"meta": {"trace":"${requestId}","httpStatus":"${status}"},
|
||||
"version": 1
|
||||
}
|
||||
errorBody: {
|
||||
"accepted": "${ok}",
|
||||
"error": {"reason":"${message}","id":"${code}"}
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
`body` 是 JSON 对象，可嵌套对象、数组和常量；`errorBody` 可选，需要同时定义 `body`。空对象 `{}` 也是有效模板。
|
||||
|
||||
| 整值占位符 | 输出值 |
|
||||
| --- | --- |
|
||||
| `${data}` | 当前接口的业务返回值，保留对象/数组/数值等原类型 |
|
||||
| `${code}` | 映射后的 string / int32 / int64 业务错误码 |
|
||||
| `${message}` | 公开提示，经 message 配置映射 |
|
||||
| `${requestId}` | 请求标识；为空时省略所在对象字段 |
|
||||
| `${ok}` | 成功为 true；有错误或 HTTP 状态 ≥400 时为 false |
|
||||
| `${status}` | HTTP 状态整数 |
|
||||
|
||||
占位符只替换整个值，不执行表达式或字符串拼接。字面量 `${data}` 写成 `$${data}`。数据为 nil 时，`dataMode: omitNil`（默认）省略所在对象字段；`always` 输出 null。数组中的占位符保留位置。模板最多嵌套 24 层。
|
||||
|
||||
`codeType` 使用与业务字段一致的类型名，默认 `string`：
|
||||
|
||||
| 类型 | 含义 | OpenAPI |
|
||||
| --- | --- | --- |
|
||||
| `string` | 字符串业务码，例如 `"OK"`、`"USER_NOT_FOUND"` | string |
|
||||
| `int32` | 32 位有符号整数，−2147483648 到 2147483647 | integer / int32 |
|
||||
| `int64` | 64 位有符号整数，−9223372036854775808 到 9223372036854775807 | integer / int64 |
|
||||
|
||||
整数类型必须提供 `successCode` 和 `errorCode`，支持 0 和负数；默认码和 `codes` 映射都会校验范围，越界或小数会报错。`int64` 的配置读取和生成代码保留完整整数精度，并按 JSON 数值输出；消费端也需要支持对应的整数精度。需要文本形式时可用 `string` 并配置字符串码。
|
||||
|
||||
旧写法 `integer` 保留兼容，沿用 ±(2^53−1) 的数值范围；新配置优先写 `int32` 或 `int64`。
|
||||
|
||||
`codes` 按逻辑错误码覆盖默认码；`messages` 优先于 `successMessage` / `errorMessage`。未配置的公开提示沿用原错误消息；内部 cause 不会被默认编码器序列化。
|
||||
|
||||
简单的平铺响应也可使用 `codeField` / `messageField` / `dataField` / `requestIdField` 快捷配置，`"-"` 禁用字段。空名称沿用旧默认值。这些字段名快捷配置不能和 `body` 混用，以免两个定义冲突。
|
||||
|
||||
## 手写路由、配置文件与三方回调
|
||||
|
||||
手写路由的应用默认配置可以放在 JSON/YAML 的 `response` 字段，也可用 Go 选项：
|
||||
|
||||
```go
|
||||
app := omni.New(omni.WithResponse(response.Config{
|
||||
Body: map[string]any{"code":"${code}", "msg":"${message}", "data":"${data}"},
|
||||
CodeType: "int32", SuccessCode: 200, ErrorCode: 9999, DataMode: "always",
|
||||
}))
|
||||
```
|
||||
|
||||
应用之间的配置独立，模板在创建时验证并复制；没有全局可变的响应格式。应用配置快照也会复制模板和映射。响应配置属于静态配置，变更后需重启。
|
||||
|
||||
单次显式输出可使用 `c.JSON(status, value)`、`c.Text(status, text)`、`c.XML(status, value)`、`c.Bytes(status, contentType, bytes)` 或 `c.NoContent()`，都绕过公共体。已经提交的响应不会再追加错误 JSON。
|
||||
|
||||
三方回调可能要求成功与失败都返回 HTTP 200，并分别输出 `success` / `fail`。通过接口编码器统一处理成功、错误和 panic：
|
||||
|
||||
```go
|
||||
ack := response.EncoderFunc(func(r response.Result) (response.Payload, error) {
|
||||
if r.Err != nil || r.Status >= 400 {
|
||||
return response.Text(200, "fail"), nil
|
||||
}
|
||||
return response.Text(200, "success"), nil
|
||||
})
|
||||
app.HandleWithResponse("POST", "/hooks/payment", ack, paymentHandler)
|
||||
```
|
||||
|
||||
编码器也可以设置 HTTP 状态、Header、XML 或任意字节。`omni.WithResponseEncoder` 设置应用默认编码器；`httpx.WithResponse` 是普通路由中间件，按中间件顺序生效。需要覆盖全局中间件提前拒绝时，应使用 `HandleWithResponse`。自定义 Registrar 可以实现 `httpx.ResponseRegistrar` 提供相同的早期挂载能力；未实现时辅助函数退化为普通路由中间件。
|
||||
|
||||
`@response raw` 表示原始 JSON，不代表任意文本/XML协议。从 v0.9.0-preview 开始，`.api` 可用 `@handlerMode manual` 配合 `@produces` 描述文本/文件等成功输出，详见 [迁移扩展](MIGRATION.md)。自定义回调错误协议仍使用上述 Go 入口，并由应用维护相应文档；生成器不会猜测自定义 Go 编码器的输出。如果在命名中间件里替换编码器，业务也必须同步维护文档。
|
||||
|
||||
框架内置路由的 404/405 使用应用默认格式；它们不属于某个 `.api` 分组。TLS 握手、畸形 HTTP、连接级过载等发生在进入应用前，仍按网络层协议处理。自定义编码器失败、panic 或返回非法状态/204 body 时，最终返回空 500，避免递归编码或泄露另一种响应体。
|
||||
|
||||
## 运行示例与验证
|
||||
|
||||
```sh
|
||||
go run ./cmd/go-omni api validate --api examples/contracts/responses.api
|
||||
go run ./cmd/go-omni api generate --api examples/contracts/responses.api \
|
||||
--module example.com/responseDemo --framework-dir . --dir ../responseDemo
|
||||
```
|
||||
|
||||
示例业务方法起初为 501，完成 Service 后就会套用声明的模板。参考 [完整 .api](examples/contracts/responses.api)。验收测试会在临时目录生成真实项目，写入业务方法，执行已生成路由，检查数字错误码、原始 JSON、鉴权错误、路由覆盖与重复生成保护。
|
||||
|
||||
|
||||
## 错误目录与 HTTP 200 失败（v0.10.0-preview）
|
||||
|
||||
错误含义由项目的 `errors.Catalog` 或 `.api errorCatalog` 集中定义，返回字段/结构仍由本页的 response 模板控制。目录提供独立的逻辑标识、对外字符串/整数码、消息、HTTP 状态，使用 `WithErrors` 或生成路由绑定。详见 [统一错误目录](errors/README.md)。
|
||||
|
||||
`response.Result.IsError()` 综合明确失败标记、Err 和 HTTP 状态判断；HTTP 200 的业务错误不会使用成功码/成功提示，仍可选择 `errorBody`。新目录的公开码与提示优先于通用兜底；与同标识 Codes/Messages 冲突会拒绝，不会静默覆盖。没有目录的旧映射保持原有行为。
|
||||
|
||||
自定义 Encoder 可读取 `Code`（逻辑标识）、`BusinessCode`（目录对外码）、Message 与 Err，并返回项目要求的最终状态和媒体类型。不要仅通过 Status 判断成功；内部原因默认只供诊断，不应由 Encoder 直接序列化 Err。RawJSON 的成功输出保持原样，失败继续交给所选错误编码器。

# go-omni CLI
|
||||
|
||||
## API 契约驱动项目
|
||||
新项目采用根目录 `main.go` 与 `internal/config、svc、logic、handler、types`。完整职责、启动扩展、流式接口和生成文件边界见 [项目指南](../../PROJECT.md)。
|
||||
|
||||
## 创建项目
|
||||
|
||||
```sh
|
||||
# 创建包含可运行问候接口的新项目
|
||||
go run ./cmd/go-omni api new --module example.com/demo --framework-dir . ../demo
|
||||
# 仓库读取权限与 PATH 配置见根目录 README
|
||||
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.13.0-preview
|
||||
go-omni new --module example.com/hello ./hello
|
||||
|
||||
# 从已有定义生成对应目录、类型、路由和业务骨架
|
||||
go run ./cmd/go-omni api generate --api examples/contracts/user.api \
|
||||
--dir ../userService --module example.com/userService --framework-dir .
|
||||
|
||||
# 校验定义；也接受 goctl 风格的 api go -api ... -dir ...
|
||||
go run ./cmd/go-omni api validate --api examples/contracts/user.api
|
||||
# 从自己的契约生成；service.api 及其相对 import 文件需要在本地存在
|
||||
go-omni new --api service.api --module example.com/example ./example
|
||||
```
|
||||
|
||||
`new --api <file>` 是契约项目的另一个入口。可以组合 `--database mysql --storage local --log-output file`，生成配置、依赖初始化与资源关闭。API 默认无数据库、无对象存储；`--database memory` 等同于不打开连接。`--force` 不允许覆盖 API 项目。初始配置选择写入 manifest，重新生成自动沿用。
|
||||
`new` 与 `api new` 统一生成契约项目；不再提供另一套 CRUD 启动目录。未实现的 Logic / 中间件骨架返回 501。进入项目执行 `go mod tidy`、`go run .`、`go build .`。
|
||||
|
||||
后续在生成项目内执行 `go-omni api generate --api api/user.api --dir .`。
|
||||
项目内可省略 `--api` / `--dir`。`api inspect` 展示路由和鉴权/业务错误，`api export` 向 stdout 导出 OpenAPI，`api generate --dry-run` 预览文件变化。`--check` 只读检查生成产物是否过期。生成器记录所有权，保留 Service / Repository / 配置 / main 的手写内容，遇到生成文件被手动修改则报冲突。新 Service 与中间件占位实现返回 501。支持 `error (...)`、具名 `auth`、路由 `@errors` / `@auth` 和多行 `@doc`；错误目录同步生成 `internal/apierrors` 调用函数。
|
||||
参数：`--database none|memory|mysql`（默认 none；memory 等同 none），`--storage none|local|s3|r2|oss`，`--log-output stdout|stderr|file`，`--log-format json|text`。基础设施按需生成，连接凭据由环境提供，不自动创建数据库、表或云资源。选择 MySQL 不会凭空生成业务表或 Repository 查询。
|
||||
|
||||
支持范围、参数语义、目录及安全更新策略见 [API 开发指南](../../API.md)。本版借鉴 go-zero 的工作流，不宣称兼容全部 goctl 语法；仍通过 Omni/httpx 保留网络层替换能力。
|
||||
存储配置和客户端位于 config/svc，业务使用统一接口。local 存储签名端点由生成器接入；上传、下载等业务路由由 `.api` 定义。认证与存储路径由项目实现。
|
||||
|
||||
## 日志与对象存储按需装配
|
||||
|
||||
新增 `--log-output stdout|stderr|file`、`--log-format json|text`、`--storage none|local|s3|r2|oss`。
|
||||
指定任意一个新选项后，生成严格的配置文件、初始化代码和项目自身的测试；不指定则保留原有轻量骨架。
|
||||
对象存储独立于 `--database memory|mysql`。只有选择文件存储才会生成文件 Handler / Service 和对应适配器。
|
||||
|
||||
开发阶段可以使用本地源码；固定远程版本的安装和验收见 [发布说明](../../RELEASE.md)：
|
||||
## 日常生成
|
||||
|
||||
```sh
|
||||
# 在 go-omni 仓库中运行；目标目录须为空。
|
||||
go run ./cmd/go-omni new --framework-dir . \
|
||||
--module example.com/fileService --log-output file --log-format json \
|
||||
--storage local ../fileService
|
||||
go-omni api validate
|
||||
go-omni api inspect
|
||||
go-omni api generate --dry-run
|
||||
go-omni api generate
|
||||
go-omni api generate --check
|
||||
go-omni api export > openapi.json
|
||||
go test ./...
|
||||
```
|
||||
|
||||
生成项目包含 `etc/config.yaml`、`internal/settings`、`internal/servicecontext/storage.go`、
|
||||
文件 Service/Handler、测试和 `MODULES.md`。按生成的 MODULES.md 配置示例 Token 和本地签名密钥后，
|
||||
`go mod tidy && go run ./cmd/server` 即可体验。云存储分别选择 `--storage s3`、`r2`、`oss`，
|
||||
再设置已有桶/凭据等环境变量；不自动创建桶或修改云资源。
|
||||
项目内自动发现 manifest 中的 API 入口，也可显式 `--api ... --dir ...`。`api go -api ... -dir ...` 为命令别名，不代表兼容全部 goctl 语法。
|
||||
|
||||
配置优先级为默认值 → YAML/JSON → 环境变量；密钥仅允许环境变量。Service 依赖统一存储接口，
|
||||
组合处负责创建客户端与有界连接池，退出时关闭自己创建的资源。文件接口提供服务端上传、直传签名、
|
||||
临时下载链接及统一错误处理；日志示例携带 requestId，文件输出默认带轮转。没有固定业务身份上下文。
|
||||
main、Gen.go、OpenAPI 和 manifest 由生成器维护；业务文件按字节保留。手改生成文件会报冲突，`--check` 检查入口与所有生成产物。没有 `--force` 覆盖业务的入口。初始基础设施 profile 在重新生成时沿用，后续项目依赖由用户修改 config/svc。
|
||||
|
||||
新模板要求 `v0.7.0-preview` 或更新版本；明确指定旧版本并启用新模块会被拒绝，
|
||||
避免模板引用旧框架不存在的接口。本地 `--framework-dir` 验证不受此限制。`--force` 可重新生成兼容配置，
|
||||
但如果切换配置会遗留引用已移除依赖的旧文件，则拒绝操作，要求使用新目录；不会自动删除修改过的代码。
|
||||
生成/预览会比较上次契约快照，提示受影响的 Logic 文件、DTO 字段和 body/流式模式变化。明确的 Logic 签名错误显示文件行号、原签名和期望签名；生成后未调整业务时，`--check` 仍返回失败。REVIEW 不强制确认，类型别名/build tags 等不确定情况交给 `go test ./...` 验证。完整行为见 [契约变更提示](../../PROJECT.md#契约变更提示)。
|
||||
|
||||
验证当前生成器：
|
||||
`@app(defaultResponse: TemplateName)` 选择 App 默认响应，路由/分组可以覆盖。错误表可以只在 Go 中维护，通过 svc.AppOptions 注册一次。上传和原始 body 的自动 Logic 参数、下载输出见 [项目指南](../../PROJECT.md)。
|
||||
|
||||
## 版本与迁移
|
||||
|
||||
CLI 与框架依赖固定使用 v0.13.0-preview。远程安装的 CLI 默认把自身版本写入 go.mod，不添加本地 replace；`--framework-version` 可显式指定已发布的兼容版本。仅在开发框架源码时使用本地替换：
|
||||
|
||||
```sh
|
||||
GO_OMNI_SCAFFOLD_INTEGRATION=1 go test -race ./cmd/go-omni/...
|
||||
python3 scripts/verifyScaffoldModules.py
|
||||
# 在 go-omni 源码仓库中执行
|
||||
go run ./cmd/go-omni new --module example.com/hello --framework-dir . ../hello
|
||||
```
|
||||
|
||||
前者覆盖两种数据库与五种文件存储选择、日志方式/格式，以及生成项目的配置、资源关闭和接口测试。
|
||||
后者实际编译启动服务，验证日志、上传/下载/直传链接、错误状态、nethttp/native 下的 SIGINT/SIGTERM 和监听端口释放。
|
||||
云端选项的测试使用本地替身，不代表 OSS/R2 实网验收；本批不访问业务服务器。报告见
|
||||
[脚手架模块验收](../../performance/scaffoldModulesLocal.json)。
|
||||
新模板需要 v0.13.0-preview 的依赖退出与端点配置能力，继续使用 manifest v2。v0.12 项目需按 [升级步骤](../../PROJECT.md#从-v012-生成项目升级) 补入 svc 生命周期字段和方法，生成器保留这些项目文件。不兼容旧目录，旧生成项目请在新目录重新生成后移入业务代码，不覆盖手写 main。独立工具命令不会被删除。受管理项目通过 `.api` 模块导入增加业务，不使用旧 `add` 命令的手动路由装配。
|
||||
|
||||
## 其他命令与远程安装
|
||||
## 数据库迁移命令
|
||||
|
||||
main 分支还提供 `go-omni add orderItems --dir /path/to/project`，向已有 GoOmni 项目增加
|
||||
Handler / Service / Repository / Model 与模块注册入口。模块名为 lowerCamelCase，
|
||||
目标目录存在时拒绝覆盖，已有启动代码保持原样。生成模块带可替换的内存 CRUD Repository，
|
||||
导入后使用 `orderItems.Register(application, repository, authMiddleware)` 注册。
|
||||
该命令从 `v0.7.0-preview` 提供；源码可用 `go build -o /tmp/go-omni ./cmd/go-omni` 构建。
|
||||
边界和验证方式见 [业务基础模块](../../MODULES.md)。
|
||||
|
||||
从远程安装，生成一个带 Handler / Service / Repository / Model 分层的服务骨架：
|
||||
|
||||
```sh
|
||||
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.7.0-preview.1
|
||||
go-omni new --module example.com/billing ./billing
|
||||
cd billing
|
||||
go mod tidy
|
||||
go run ./cmd/server
|
||||
```
|
||||
|
||||
通过 `go install ...@版本` 安装的 CLI 从构建信息中读取版本，并把它固定到生成项目的
|
||||
`go.mod`。不会使用不存在的 `v0.0.0`，也不会在普通业务目录中添加本地 `replace`。
|
||||
|
||||
需要选择其他已发布版本时，使用完整版本号：
|
||||
|
||||
```sh
|
||||
go-omni new --framework-version v0.6.0-preview --module example.com/billing ./billing
|
||||
```
|
||||
|
||||
`--framework-version` 禁用自动本地替换；`main`、`latest` 等浮动引用不接受为固定版本。
|
||||
源码构建的 CLI 使用代码中声明的目标发布版本；该版本未发布时请显式选择已发布版本，或用 `--framework-dir` 验证本地源码。
|
||||
|
||||
在 GoOmni 源码目录执行时，命令会自动在生成项目的 `go.mod` 中加入本地
|
||||
`replace git.yuntuo.hk/k2safe/go-omni => ...`，便于立即运行和测试。目标目录非空时命令会停止，明确传入
|
||||
`--force` 才会覆盖脚手架文件。
|
||||
|
||||
也可以在任意目录显式指定源码路径：
|
||||
|
||||
```sh
|
||||
go-omni new --framework-dir /path/to/go-omni --module example.com/billing ./billing
|
||||
```
|
||||
|
||||
默认生成内存存储版本；选择 MySQL 时：
|
||||
|
||||
```sh
|
||||
go-omni new --database mysql --module example.com/billing ./billing
|
||||
```

|
||||
MySQL 项目额外包含 `schema.sql`、MySQL Repository 和可选的数据库集成测试。
|
||||
先应用建表脚本，再设置 `GO_OMNI_DB_DSN` 启动。ServiceContext 负责连接池初始化、表结构检查、
|
||||
就绪探针注册和关闭。两种模式都提供用户 CRUD、分页、输入校验和统一错误响应。
|
||||
|
||||
生成服务默认包含 `/health/live`、`/health/ready` 和示例 `/users` CRUD。
|
||||
退出信号通过 `signal.NotifyContext` 传入 `RunContext`，Logger 的关闭函数注册到应用生命周期。
|
||||
|
||||
发布验收使用 Python 3 标准库脚本，不需要额外 Python 依赖：
|
||||
|
||||
```sh
|
||||
python3 scripts/verifyScaffold.py --version v0.6.0-preview
|
||||
python3 scripts/verifyDatabase.py --version v0.6.0-preview
|
||||
```
|
||||
|
||||
脚本在源码目录外安装远程 CLI、生成项目，确认固定版本且没有 `replace`，再下载依赖、
|
||||
编译、请求接口，并对真实二进制分别发送 `SIGINT` 和 `SIGTERM`。同时验证框架 `Run` 的
|
||||
信号处理和清理回调。每个进程都必须退出码为 0、释放监听端口；临时项目和测试进程会被清理。
|
||||
|
||||
发布前验证当前源码：
|
||||
|
||||
```sh
|
||||
go build -o /tmp/go-omni ./cmd/go-omni
|
||||
python3 scripts/verifyScaffold.py --cli /tmp/go-omni --framework-dir .
|
||||
python3 scripts/verifyDatabase.py --cli /tmp/go-omni --framework-dir .
|
||||
```
|
||||
|
||||
数据库验收需要本地 Docker，使用独立 MySQL 8.4 容器；不会连接已有业务数据库，结束后清理测试容器与数据卷。
|
||||
|
||||
## 显式迁移（main）
|
||||
|
||||
SQL 命名为 `0001_createUsers.up.sql`。先预览版本和 SHA-256 清单：
|
||||
保留独立迁移工具，应用启动不自动迁移：
|
||||
|
||||
```sh
|
||||
go-omni migrate --dir migrations
|
||||
```
|
||||
|
||||
部署步骤配置 `GO_OMNI_DB_DSN`，显式执行：
|
||||
|
||||
```sh
|
||||
# 检查预览，配置 GO_OMNI_DB_DSN 后显式应用
|
||||
go-omni migrate --dir migrations --apply
|
||||
```
|
||||
|
||||
预览不连接数据库；应用启动不自动迁移。失败保留 dirty 状态，不提供自动 down/force。
|
||||
脚手架原有 `schema.sql` 不会自动变成有版本的迁移，已有库需要先确定基线。详见 [扩展模块](../../ADVANCED.md)。
|
||||
SQL 命名示例 `0001_createUsers.up.sql`；预览只显示版本和 SHA-256，不连接数据库。失败保留 dirty 状态，不自动 down/force。细节见 [扩展模块](../../ADVANCED.md)。

The API response type describes business data. Declare response Name (...) and

select the App default with @app(defaultResponse: Name) in the entry API.
|

@server(response: Name) and @response Name override it for groups/routes;

@response raw returns the business JSON directly. Without a template, the default
|
||||
envelope includes code, message, data and requestId. Generated routes and OpenAPI
|
||||
use the same contract. 404/405 and ordinary App routes use the declared App default.
|
||||
No template is selected by declaration/import order. Without @app, existing framework
|
||||
response defaults apply. An explicit API App default takes precedence over response
|
||||
options in svc, keeping generated routes and OpenAPI consistent.
|
||||
Handlers reject nil successful responses. Body DTOs use application/json and have a 1 MiB limit by default.
|
||||
Use @body(maxBytes: ...) for route limits. @body(mode: raw|multipart; maxBytes: ...)

@produces "application/octet-stream" (or another concrete media type) generates a

Signature verification and storage policy belong to Logic/middleware. A consumed

request stream cannot be reread automatically; use one reader owner or explicitly

The generated main runs HTTP draining before closing svc resources, then the logger.

Do not close borrowed resources or attach duplicate cleanup hooks to App. The startup

their own lifetime, canceled by OnClose after HTTP draining.

svc.RequestShutdown(err) lets a dependency report a fatal service failure.
|

It returns immediately. Generated main stops accepting requests, drains them,

closes dependencies and logs, then exits nonzero with the original cause.
|

nil requests a normal stop. Concurrent calls keep the first non-nil failure;
|

notifications during initialization or draining are retained. Close must stop

and join project-owned monitors before the final shutdown result is returned.
|

The svc lifecycle context signals draining, not permission to close resources

## Connector 接入（v0.9.1-preview）
|
||||
|
||||
项目已有 `database/sql/driver.Connector` 时使用 `OpenConnector`。这是标准驱动接口，核心包不增加具体驱动依赖。项目可以在同一进程创建多个使用不同证书、日志、拨号策略的连接池。
|
||||
|
||||
下面是 MySQL 的完整组装函数；连接地址、凭据、TLS 和驱动 Logger 都从调用方传入，不在框架中约定：
|
||||
|
||||
```go
|
||||
package connection
|
||||
|
||||
import (
|
||||
"context"
|
||||
"crypto/tls"
|
||||
"github.com/go-sql-driver/mysql"
|
||||
"git.yuntuo.hk/k2safe/go-omni/database"
|
||||
)
|
||||
|
||||
func Open(ctx context.Context, address, user, password, name string,
|
||||
tlsConfig *tls.Config, logger mysql.Logger,
|
||||
pool database.PoolConfig) (*database.DB, error) {
|
||||
cfg := mysql.NewConfig()
|
||||
cfg.Net, cfg.Addr = "tcp", address
|
||||
cfg.User, cfg.Passwd, cfg.DBName = user, password, name
|
||||
cfg.TLS = tlsConfig // 项目设置 RootCAs、ServerName、MinVersion 等
|
||||
if logger != nil {
|
||||
cfg.Logger = logger // 项目现有的 Print(...any) 日志适配器
|
||||
}
|
||||
connector, err := mysql.NewConnector(cfg)
|
||||
if err != nil {
|
||||
return nil, err
|
||||
}
|
||||
return database.OpenConnector(ctx, connector, pool)
|
||||
}
|
||||
```
|
||||
|
||||
调用时以 `database.DefaultPoolConfig()` 为起点，按项目需要调整。已有 `database.Config` 可调用 `.PoolConfig()` 提取池设置；`ConfigFromEnv` / `ApplyEnv` 仍是 DSN 入口，不用为 Connector 填假 DSN。`PoolConfig` 支持通过 `config.DecodeFile` 加载项目的 JSON/YAML 嵌套配置，环境覆盖由项目按自己的驱动配置组织。
|
||||
|
||||
| PoolConfig 字段 | 默认值 / 含义 |
|
||||
| --- | --- |
|
||||
| `MaxOpenConns` | `10`；`0` 表示不限制 |
|
||||
| `MaxIdleConns` | `5`；`0` 禁止保留空闲连接 |
|
||||
| `ConnMaxLifetime` | `30m`；`0` 不因连接年龄回收 |
|
||||
| `ConnMaxIdleTime` | `5m`；`0` 不因空闲时长回收 |
|
||||
| `PingTimeout` | `5s`；必须为正，约束启动 Ping 和 Health 等待 |
|
||||
|
||||
返回的 `*database.DB` 嵌入 `*sql.DB`，可使用 `QueryContext`、`ExecContext`、`Stats`，以及框架的 `Health`、`InTx`。需要标准数据库指针的 ORM/迁移器可取 `db.DB`；不要重复建立池。项目负责驱动支持的 context 取消与读写超时设置，框架不能强制中断不遵守 context 的自定义驱动。
|
||||
|
||||
**生命周期：** nil/带类型的 nil Connector、非法池参数、启动前已取消的 context 会在创建池前返回，Connector 仍归调用方。进入 `sql.OpenDB` 后由池持有；启动 Ping 失败自动关闭，成功后由调用方负责 `db.Close`，通常注册 `app.OnShutdown(db.Close)`。若 Connector 实现 `io.Closer`，遵循标准 `database/sql` 规则随池关闭；有资源的 Connector 不应跨多个池共享。资源初始化过程中、注册退出回调之前若业务校验失败，项目也须关闭池。
|
||||
|
||||
`db.PoolConfig()` 返回池配置快照。Connector 入口的 `db.Config()` 中 `Driver` / `DSN` 为空，不能用它重建 Connector。TLS、Logger、驱动版本检查、字符集、时区以及迁移规则保持由项目负责；不写入框架配置快照。
|
||||
|
||||
验收脚本使用独立本地 MySQL 8.4 容器（1 CPU / 768 MiB），自动生成测试 CA/证书与随机凭据，检查 TLS 信任/主机名、两池配置隔离、驱动日志、事务和 HTTP 超时，结束后清理本次资源：
|
||||
|
||||
```sh

||||

# 发布后通过全新 module cache 验证远程依赖，无本地 replace：

# 统一错误目录
|
||||
|
||||
从 `v0.10.0-preview` 起，业务可以只返回逻辑错误标识，框架从项目目录取得 HTTP 状态、对外业务码与公开提示。目录不依赖具体业务、数据库、身份模型或网络层，也不定义固定返回体。
|
||||
|
||||
## 基本规则
|
||||
|
||||
- `key` / `Definitions` 的 map key 是唯一逻辑标识，例如 `USERNAME_INVALID`、`user.notFound`。API 新目录允许项目自己的标识命名；旧 `error (...)` 声明保持原有大写标识规则。
|
||||
- `code` 是对外业务码，支持字符串、整数，同一个码可以由多个不同标识使用。JSON/YAML 和 `.api` 读取整数时保留 int64 精度。
|
||||
- `DefaultStatus` / `defaultStatus` 只为目录中未写状态的条目提供默认值，省略时为 400。项目可设为 200；单项 `Status` / `status` 优先。
|
||||
- 目录条目允许有响应体的最终 HTTP 状态：200..599，排除 204、205、304。成功输出与错误输出分开；HTTP 200 并不把错误变成成功。
|
||||
- 数字码类型与范围遵守选中响应的 `codeType`（string/int32/int64；integer 是旧别名）。不同路由可以选择不同类型的公共响应与目录。
|
||||
- 新目录声明完整公开提示；每条错误的业务码和提示优先于统一 `errorCode` / `errorMessage` 兜底。旧的同标识 `codes` / `messages` 若与目录冲突，初始化或契约编译报错；相同值允许保留，便于逐步迁移。
|
||||
|
||||
## 手写项目
|
||||
|
||||
```go
|
||||
import (
|
||||
omni "git.yuntuo.hk/k2safe/go-omni"
|
||||
omnierrors "git.yuntuo.hk/k2safe/go-omni/errors"
|
||||
"git.yuntuo.hk/k2safe/go-omni/response"
|
||||
)
|
||||
|
||||
catalog := omnierrors.Catalog{
|
||||
DefaultStatus: 200,
|
||||
Definitions: map[string]omnierrors.Definition{
|
||||
"USERNAME_INVALID": {Code: 400002, Message: "用户名格式不正确"},
|
||||
"PASSWORD_INVALID": {Code: 400002, Message: "密码格式不正确"},
|
||||
"FORBIDDEN": {Status: 403, Code: 403001, Message: "没有权限"},
|
||||
},
|
||||
}
|
||||
app := omni.New(
|
||||
omni.WithErrors(catalog),
|
||||
omni.WithResponse(response.Config{
|
||||
CodeType: "int32", SuccessCode: 0, ErrorCode: 9999,
|
||||
MessageField: "msg", DataMode: "always",
|
||||
}),
|
||||
)
|
||||
```
|
||||
|
||||
Service 返回 `omnierrors.ByCode("USERNAME_INVALID")`，或 `.WithCause(err)`。业务无需接收 App/HTTP Context。目录属于 App，初始化时校验并复制；后续修改原 map 不影响正在服务的应用。配置快照也不暴露内部 map。
|
||||
|
||||
`NewRegistry(catalog)` / `MustRegistry(catalog)` 可在 CLI/任务消费者等非 HTTP 入口使用；`registry.Resolve(err)` 返回独立的 `*APIError`，包含逻辑 `Code`、对外 `BusinessCode`、Status、Message 与内部 Cause。每次调用都创建新对象；不要自行将一个可变错误对象保存为共享单例再调用 WithCause。
|
||||
|
||||
原有 `New(status, key, message)` 等明确错误也能被同标识目录条目覆盖；未在目录中的明确错误沿用原状态与提示。未配置目录时，原有行为保持。Go 目录允许 `Definition.Code == nil` 以继续使用旧 Codes/errorCode 映射；新 `.api errorCatalog` 要求显式 code。
|
||||
|
||||
## Go 维护错误目录，生成路由继承 App（v0.11.1-preview）
|
||||
|
||||
错误可以只在 Go 中定义，并在 `omni.New(omni.WithErrors(catalog), ...)` 注册一次。`.api` 只写接口、请求/响应 DTO 和响应格式，**无需再声明 errorCatalog，也无需为每条路由列出错误**。业务直接返回 `ByCode(key)` 或 `ByCode(key).WithParams(...)`。
|
||||
|
||||
选择规则：
|
||||
|
||||
- 生成路由没有有效的 `@errors` / `@server errors` 列表时，继承 App 目录，包括 App 配置的 INTERNAL_ERROR 中文兜底。
|
||||
- 路由显式引用了错误定义时，使用该路由自己的目录；不与 App 目录合并，保持独立语义。
|
||||
- `@errors none` 清空 `.api` 分组继承的错误列表；清空后按没有路由目录处理，继承 App，而不是禁用错误处理。
|
||||
- 错误目录与响应格式独立选择。继承 App 错误不覆盖 `.api` 的响应模板、RawJSON、绑定方式和请求体限额；响应 `codeType` 需能表示目录中的业务码。
|
||||
- App 全局中间件提前返回错误、普通 Handler 和 Context 克隆遵循相同规则。
|
||||
|
||||
`response.WithErrors` / `MustWithErrors` 收到空目录时返回原 Encoder，不建立空 Registry，也不在编码时再次解析原始 error。已有 v0.11.0 生成代码中的空包装因此也能通过升级运行时修复；同步升级 CLI 重新生成则不再产生空包装。
|
||||
|
||||
可生成的示例见 [errorInheritance.api](../examples/contracts/errorInheritance.api)。Go 目录是在运行时注册的，CLI 不执行项目 Go 代码；静态 OpenAPI 保留 `.api` 中的响应结构，不会自动枚举 Go 目录的具体错误码、提示及状态。这不影响运行时接入，也不要求重复维护目录。
|
||||
|
||||
## 文件配置
|
||||
|
||||
下面是生成项目的 `etc/config.yaml` 结构；直接 `config.LoadFile` 加载框架配置时去掉外面的 `server`。手写 main 需显式将加载结果传入 `WithConfig`。
|
||||
|
||||
```yaml
|
||||
server:
|
||||
errors:
|
||||
defaultStatus: 200
|
||||
definitions:
|
||||
USERNAME_INVALID:
|
||||
code: 400002
|
||||
message: 用户名格式不正确
|
||||
FORBIDDEN:
|
||||
status: 403
|
||||
code: 403001
|
||||
message: 没有权限
|
||||
response:
|
||||
codeType: int32
|
||||
successCode: 0
|
||||
errorCode: 9999
|
||||
messageField: msg
|
||||
dataMode: always
|
||||
```
|
||||
|
||||
重复 JSON/YAML key、未知字段、非法状态、非整数数值及类型/范围错误会拒绝加载。目录不支持运行时热更新；修改后重新启动，避免请求与文档在运行期间漂移。
|
||||
|
||||
## .api：定义一次，生成调用与文档
|
||||
|
||||
完整示例见 [errors.api](../examples/contracts/errors.api)。语法：
|
||||
|
||||
```text
|
||||
errorCatalog CommonErrors (
|
||||
defaultStatus: 200
|
||||
errors: {
|
||||
"UsernameInvalid": {"key": "USERNAME_INVALID", "code": 400002, "message": "用户名格式不正确"},
|
||||
"PasswordInvalid": {"key": "PASSWORD_INVALID", "code": 400002, "message": "密码格式不正确"}
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
目录可放进公共 `.api` 再 import；也可以拆成多个命名目录，各自设置默认状态。生成器合并定义时检查目录名、函数名、逻辑标识冲突。`Catalog` 是生成包的保留函数名。目录对象的键是生成的 UpperCamelCase 函数名，条目的 `key` 是运行时逻辑标识，二者用途不同。
|
||||
|
||||
在 `@server` 的 `errors` 或路由 `@errors` 中引用函数名，响应仍通过原有 `response` 声明选择：
|
||||
|
||||
```text
|
||||
@server (
|
||||
response: CommonResponse
|
||||
errors: UsernameInvalid, PasswordInvalid
|
||||
)
|
||||
service account-api {
|
||||
@handler token
|
||||
post /token returns (TokenResponse)
|
||||
}
|
||||
```
|
||||
|
||||
生成结果包括：
|
||||
|
||||
- `apierrors.UsernameInvalid()` 等无参数函数，每次返回独立错误，支持 WithCause。
|
||||
- `apierrors.CodeUsernameInvalid` 等逻辑标识常量。
|
||||
- `apierrors.Catalog()`：整个契约的可复制运行时目录，方便手写路由复用。
|
||||
- 自动绑定到生成路由的目录：只包含该路由通过 `@errors` / `@server errors` 声明的错误，在 App 全局中间件之前生效，支持认证提前返回和缓冲克隆。
|
||||
- OpenAPI 的错误响应与示例。同一 HTTP 200 下用 `anyOf` 同时描述成功 DTO 和错误体；多个错误共用数字码时保持多个示例；raw 成功体与失败公共体也分开描述。
|
||||
|
||||
业务直接 `return TokenResponse{}, apierrors.UsernameInvalid()`。也可以返回 `omnierrors.ByCode(apierrors.CodeUsernameInvalid)`；使用标识引用时，当前生效的目录必须包含该错误。采用 `.api` 管理路由独立目录时，新增错误需补充该路由的 `@errors`；采用 Go 注册 App 目录时，无需在 `.api` 重复声明。
|
||||
|
||||
显式声明了错误列表的生成路由使用 `.api` 目录，未声明的路由继承 App；响应格式始终按各自配置选择。手写路由可在 main 用 `omni.WithErrors(apierrors.Catalog())` 复用目录并选择兼容的 `WithResponse`。已有手写文件保持不动。
|
||||
|
||||
## 提示模板参数（v0.11.0-preview）
|
||||
|
||||
模板属于错误目录，业务只传具体值。参数用**有序列表**声明，顺序就是生成函数的参数顺序；每个参数均为必传，`example` 只用于文档。
|
||||
|
||||
```text
|
||||
errorCatalog CommonErrors (
|
||||
defaultStatus: 200
|
||||
errors: {
|
||||
"TextTooLong": {
|
||||
"key": "TEXT_TOO_LONG",
|
||||
"code": 400002,
|
||||
"message": "{label}不能超过{max}个字符",
|
||||
"params": [
|
||||
{"name": "label", "type": "string", "example": "企业名称"},
|
||||
{"name": "max", "type": "int", "example": 100}
|
||||
]
|
||||
}
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
与数字码匹配的公共响应及路由声明见完整 [errorParams.api](../examples/contracts/errorParams.api)。生成后：
|
||||
|
||||
```go
|
||||
apierrors.TextTooLong("企业名称", 100) // Message：企业名称不能超过100个字符
|
||||
apierrors.TextTooLong("备注", 500) // Message：备注不能超过500个字符
|
||||
apierrors.UsernameInvalid() // 原有固定错误保持无参数
|
||||
```
|
||||
|
||||
生成函数在返回前完成解析，非 HTTP Service、任务或 CLI 同样能直接读取完整 Message。调用 `.WithCause(err)` 保留内部原因及 `errors.Is/As` 错误链，不自动把原因加入提示。每次返回新对象，不能把可变错误保存成共享单例。
|
||||
|
||||
运行时入口使用同一个解析器：
|
||||
|
||||
```go
|
||||
err := omnierrors.ByCode("TEXT_TOO_LONG").WithParams(map[string]any{
|
||||
"label": "企业名称",
|
||||
"max": 100,
|
||||
})
|
||||
// HTTP：将 err 返回，当前 App/路由目录负责解析。
|
||||
// 非 HTTP：使用项目自己的目录显式解析。
|
||||
registry := omnierrors.MustRegistry(apierrors.Catalog())
|
||||
resolved := registry.Resolve(err)
|
||||
fmt.Println(resolved.Message) // 企业名称不能超过100个字符
|
||||
```
|
||||
|
||||
Go 配置中的 `Definition.Params` 是 `[]omnierrors.Parameter`，JSON/YAML 使用相同的 `params` 数组。目录在初始化时复制并编译模板；`WithParams` 返回新错误并复制参数，之后修改原 map 不会改变该错误。重复解析、路由策略和 Context 缓冲克隆保留参数。
|
||||
|
||||
规则如下：
|
||||
|
||||
- 参数名使用 lowerCamelCase，并且不是 Go 关键字。顺序是调用 API 的一部分，重排或变更类型需要同步调整调用方。
|
||||
- 支持 `string`、`bool`、`int`、`int32`、`int64`、`float64`。运行时允许整数类型之间按声明范围归一化，拒绝将字符串或浮点数隐式转成整数；float64 要求有限数值。`int` 范围随 Go 目标平台变化，需要固定位宽时选 int32/int64。
|
||||
- 只接受标量，不接受 nil、切片、map、指针、任意对象或 Stringer。通过 JSON 构建运行时参数时使用 `Decoder.UseNumber()`，避免丢失大整数精度。
|
||||
- 模板使用 `{name}`；同一参数可重复出现。`{{` / `}}` 表示字面花括号。插入值不会再次解析，即使 label 本身包含 `{max}`，也只是普通文本。
|
||||
- **省略 params** 表示旧固定提示，字面花括号不变。不接受空 params 数组；重复参数、未声明占位符、未使用参数、不匹配的花括号、非法类型及错误的 example 会在目录加载/契约校验时失败。
|
||||
- 运行时缺参、多传参数、类型或范围错误转为系统错误兜底；不会将原始模板或参数值作为诊断发给客户端。内部 cause 中可通过 `errors.As` 获取 `*omnierrors.ParamError`，访问日志带 `errorParameter` 诊断，不自动记录参数值。
|
||||
- 项目可以配置固定的 INTERNAL_ERROR 兜底；若它自身也需要参数且无法解析，则回退框架固定 500，避免递归失败。
|
||||
- 模板错误的提示只放目录中；同标识再配置旧 `messages` 会被拒绝。响应字段、HTTP 状态、`data:null` 仍由项目策略决定，例如 `dataMode: always` 保留空 data。
|
||||
|
||||
OpenAPI 的 `x-omni-errors` 保留模板和有序参数定义，响应 examples 使用同一个解析器生成具体文案。未提供 example 时使用稳定样例（string 使用参数名，bool 使用 false，数值使用 1）；这些样例不充当运行时默认值，也不是新增 HTTP 请求参数。
|
||||
|
||||
幂等重放保存当次**已解析的公开错误快照**，保留原响应与失败信息。目录更新后，仍在有效期内的重放不会被新文案覆盖；快照不持久化原始参数或内部 cause。整数业务码以不受 JSON 中间层浮点转换影响的方式保存。旧缓存仅保留已有错误标识，不能补推当时缺失的提示与业务码。共享存储的错误快照另受 MaxResponseBytes 限额约束，超限保留不可重放记录，避免重复执行业务。
|
||||
|
||||
## 特殊协议与失败信息
|
||||
|
||||
`response.WithErrors(catalog, encoder)` / `MustWithErrors` 可绑定路由专用策略，再通过 `HandleWithResponse` 注册。内置模板校验目录码类型与旧映射；自定义 Encoder 自行决定最终 HTTP 状态、媒体类型和字段结构，可将失败转换成第三方要求的文本/XML 回执。一个 Encoder 作用域不叠加不同目录；外层空目录或相同目录不会覆盖已有目录。
|
||||
|
||||
Encoder 的 `response.Result` 包含逻辑 `Code`、对外 `BusinessCode`、公开 `Message`、原始 `Err` 及 `Failed`。使用 `result.IsError()` 判断失败，不要仅判断 `Status >= 400`。`RawJSON` 仅让成功结果保持未包装，HTTP 200 的失败仍使用选定错误策略。`c.Text` / `c.XML` / `c.JSON` 等直接输出及已提交的标准 Handler 响应不会被目录重新包装。
|
||||
|
||||
启用访问日志时，记录最终写出的 HTTP 状态，并保留 `failed`、`errorKey` 和可用的 `businessCode`。内置指标将已处理的业务失败计入 Errors；链路记录保留 HTTP 200 和业务失败标记。标准中间件桥接和本地/共享幂等重放保留失败标识；已有缓存条目没有新增元数据时无法追溯识别业务失败，等待正常过期即可。
|
||||
|
||||
未知的 ByCode 标识、普通 error、panic 默认走 `INTERNAL_ERROR`，公开兜底不暴露 cause。项目可显式配置 INTERNAL_ERROR 条目，但目录 DefaultStatus 本身不会改变系统兜底。启用访问日志后，可通过原始 error 追查未知标识和内部原因。
|
||||
|
||||
## 升级
|
||||
|
||||
```sh
|
||||
go get git.yuntuo.hk/k2safe/go-omni@v0.11.1-preview
|
||||
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.11.1-preview
|
||||
go-omni api generate --dry-run
|
||||
go-omni api generate
|
||||
go test ./...
|
||||
```
|
||||
|
||||
先升级框架依赖，再用同版 CLI 生成；新生成代码最低依赖 v0.11.0-preview。原来的错误构造函数、旧 `error (...)`、Codes/Messages 与已生成代码可继续运行。把业务中散落的状态/提示逐步替换为生成函数属于项目迁移工作，框架不会自动改写业务逻辑。
