# 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`。
|
||||
|
||||
v0.14 的 [完整开发指南](DEVELOPMENT.md) 说明响应根类型、`@request`、multipart 字段、注释/格式化、Go 错误目录导出与共享契约。

## 与 go-zero 的对应关系

调研参考了 go-zero 官方的 [API DSL](https://go-zero.dev/reference/api-dsl/)、[参数规则](https://go-zero.dev/reference/api-dsl/parameter/)、[goctl API](https://go-zero.dev/reference/cli-guide/api/) 和 [项目结构](https://go-zero.dev/concepts/project-structure/)。借鉴其声明接口后生成项目的工作方式：统一的类型定义、路由声明、分组、前缀和命名中间件。实现独立编写，不引入 go-zero 或 Gin 运行时依赖。

||||
## 实施与验收清单
|
||||
|
||||

|
||||
- [x] 配置：项目完整结构体环境覆盖；默认值→文件→环境；嵌套、duration、slice、显式零值、空值策略、必填与脱敏；日志无副作用完整校验。
|
||||
- [x] 数据库：官方 MySQL 结构化配置/TLS/驱动日志适配，继续复用 OpenConnector 和唯一连接池；独立启动检查、失败清理、生成器接入；不内置版本/表结构/业务错误策略。
|
||||
- [x] 响应契约：数组、可空对象、成功 null、独立 HTTP 204；Logic/Handler/OpenAPI/漂移检查一致。
|
||||
- [x] 请求契约：未知 query、JSON UTF-8/charset、无 Body/必填空对象/可选 Body，App 默认与路由覆盖；scalar/any/数组/大小限制一致，普通 JSON 只绑定一次。
|
||||
- [x] 上传：声明文件/文本/JSON 字段，重复/未知/必填/单字段/单文件/总量限制；有界暂存与清理，调用 Logic 前完成普通表单校验；保留流式扩展与 Complete 约定。
|
||||
- [x] 文档工具：字段注释、example/枚举描述进入 DTO 与 OpenAPI；保注释、幂等格式化及 check；显式 Go 错误目录元数据导出与文档合并，不自动执行项目代码。

- [x] 共享契约：受控 roots/摘要、循环/深度/文件数/路径保护；分源文件 DTO、多个独立 module 的工作区检查；版本提示与基础模板升级预览，保留业务文件。
|
||||
- [x] 集成：实际生成项目验证新能力、连续生成、业务文件保留、失败清理、nethttp/native 请求与退出；现有错误继承/参数/上传下载回归。
|
||||
- [x] 最终回归：全量 race（含生成器集成）、vet、build、格式化/链接检查；使用说明、迁移步骤及验收报告完整，发布后远程无 replace 验收。

已发布 `v0.14.0-preview`。逐项验收、可替换的业务适配点与远程报告见 [验收记录](reports/businessDevelopmentAcceptance.md)；接入和升级见 [开发指南](DEVELOPMENT.md)。
|
||||
|
||||
## 核心约定
|
||||
|
||||
响应与错误码由项目配置。字段与请求策略由契约表达；基础设施采用可选适配器，保留标准 Connector。所有业务依赖在请求排空后关闭；框架不重试写操作、不自动迁移业务表、不关闭借用资源。
|
||||
|
||||
普通 multipart 为保证进入 Logic 前完成校验，以有界复制暂存到临时文件；框架清理自己创建的资源。纯流式路径明确由调用方在提交持久副作用前完成输入检查。
|
||||
|
||||
不修改 eTax/ePay 业务，不连接既有业务服务器。真实基础设施如需验证，只使用本轮隔离资源。验收报告明确区分单元测试、生成消费者测试与真实服务测试。

# Changelog
|
||||
|
||||
## v0.13.0-preview（2026-09-24）
|
||||
|
||||
- 新增通用 lifecycle.Controller，svc.RequestShutdown 支持依赖主动通知正常停止或致命故障，通知不阻塞，首个故障原因保留；生成入口排空 HTTP 后关闭依赖与日志，故障退出码为 1。
|
||||
- App.RunContext、ServeContext、RunWith 保留自定义 context 取消原因；正常信号取消仍正常返回。
|
||||
- 健康检查默认使用 App 响应模板和错误目录，支持 raw JSON；HTTP 状态保持 200/503，避免业务 HTTP 200 策略掩盖未就绪。内部探针原因仅供日志，失败状态继续记录到日志/指标。
|
||||
- 生成项目通过 server.endpoints 配置 liveness/readiness/openapi 的开关与路径；全局中间件继续生效，OpenAPI 保持原始规范。禁用端点不保留路径，启用路径与业务 GET/参数/通配路由冲突时在监听前报错。
|
||||
- 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。

# 通用业务开发指南（v0.18.0-preview）
|
||||
|
||||
从 [README](README.md) 创建服务后，业务主要维护 `.api`、配置、`svc.Init`、Logic、Repository 和项目中间件。本页说明通用接入能力；字段、错误码、权限、表结构和事务边界都由项目定义。
|
||||
|
||||
本版新增的公共字段组合、可选结构映射、自动中间件工厂和 Repository 开关，见 [生成能力指南](GENERATION.md)。
|
||||
|
||||
## 返回数组、可空对象和 null
|
||||
|
||||
```text
|
||||
@handler list
|
||||
get /items returns ([]Item)
|
||||
|
||||
@handler find
|
||||
get /item returns (*Item)
|
||||
|
||||
@handler save
|
||||
post /item returns (null)
|
||||
|
||||
@handler remove
|
||||
delete /item
|
||||
```
|
||||
|
||||
| 契约 | Logic 返回 | 成功数据 |
|
||||
| --- | --- | --- |
|
||||
| `returns (Item)` | `(*types.Item, error)` | 对象；nil 被视为实现错误 |
|
||||
| `returns ([]Item)` | `([]types.Item, error)` | 对象数组；nil 统一输出 `[]` |
|
||||
| `returns ([]string)` | `([]string, error)` | 字符串数组 |
|
||||
| `returns ([]int64)` / `([]bool)` | `([]int64, error)` / `([]bool, error)` | 数值 / 布尔数组 |
|
||||
| `returns ([]any)` | `([]any, error)` | 动态 JSON 数组，元素允许对象、数组、标量和 null |
|
||||
| `returns (*Item)` | `(*types.Item, error)` | 对象或 `null` |
|
||||
| `returns (null)` | `error` | HTTP 200 和空业务数据 |
|
||||
| 不写 returns | `error` | HTTP 204，无响应体 |
|
||||
|
||||
统一响应中的空数据是否显示，仍遵循项目模板的 `dataMode`；需要 `data:null` 就设置 `dataMode: always`。`@response raw` 输出业务数据本身，包括 `[]`、对象或 `null`。可用 `@status 201/202`；204 不能声明响应类型。嵌套字段继续支持既有 slice/map/pointer/scalar/any。
|
||||
|
||||
基础类型数组还支持 int/int8/int16/int32、uint/uint16/uint32/uint64、float32/float64。nil 根数组都输出 `[]`；`[]any` 在 OpenAPI 中是 `type: array, items: {}`，不限制元素形状，但元素必须可被标准 JSON 编码器序列化。`[]uint8`（Go 的 byte slice）会编码为 base64，故明确拒绝；数字数组可用 `[]int32`，二进制用下载接口。当前不支持根嵌套数组或根自定义 scalar 数组。
|
||||
|
||||
## 契约驱动的请求策略
|
||||
|
||||
入口文件可以声明默认策略，单个接口按需覆盖：
|
||||
|
||||
```text
|
||||
@app (
|
||||
defaultResponse: CommonResponse
|
||||
request: {"unknownQuery":"reject", "utf8":"reject", "charset":"utf8"}
|
||||
)
|
||||
|
||||
@handler create
|
||||
@request (body: required)
|
||||
post /items (CreateReq) returns (Item)
|
||||
|
||||
@handler touch
|
||||
@request (body: emptyObject)
|
||||
post /touch returns (null)
|
||||
```
|
||||
|
||||
- `unknownQuery: reject|ignore`：是否拒绝未声明的 URL 查询字段；重复标量仍拒绝，数组用重复的同名 query。
|
||||
- `utf8: reject|replace`：拒绝原始非法 UTF-8，或采用 JSON 的替换字符行为。不是只检查解码后的字符串。
|
||||
- `charset: utf8|any`：`utf8` 仅接受未声明 charset 或 `utf-8`；不会对其他编码做转码。
|
||||
- `body: auto|required|optional|none|emptyObject`：auto 按 JSON 字段推断；required 要求一个对象；optional 允许完全没有 body，但提供 body 后仍完整校验；none 禁止任何 body 字节；emptyObject 必须是 `{}`。
|
||||
|
||||
未设置的项继承 App 的 `config.Config.Request`，最后采用既有默认行为。`.api` 的 `@app` 显式字段优先于项目配置；路由 `@request` 优先于 App。raw/multipart 使用各自解析流程，不能套 JSON body 策略。普通 JSON 只解析一次；重复/未知 JSON 字段、约束、scalar 和 `any` 仍使用同一编译器。自定义 binder/manual Handler 的输入逻辑由项目显式负责。
|
||||
|
||||
没有 body 与提供 `{}` 不等价。optional 无 body 时 JSON 字段保留零值；需要业务区分是否出现某字段时使用 optional 指针字段。raw/multipart 不继承 App 的 JSON body 策略；GET/HEAD 如遇 App 的 required/optional/emptyObject 默认值，须明确覆盖为 auto 或 none。参数校验不会替代企业权限、记账规则或数据库约束。
|
||||
|
||||
## 声明式 multipart
|
||||
|
||||
```text
|
||||
type UploadReq {
|
||||
Title string `multipart:"title" binding:"required,max=80"`
|
||||
Metadata AttachmentMeta `multipartJSON:"metadata,maxBytes=16384"`
|
||||
Attachment File `file:"attachment,maxBytes=10485760"`
|
||||
Extras []File `file:"extras,optional,maxFiles=3,maxBytes=1048576"`
|
||||
}
|
||||
type AttachmentMeta {
|
||||
Category string `json:"category"`
|
||||
}
|
||||
|
||||
@handler upload
|
||||
@body (mode: multipart; maxBytes: 16777216; maxParts: 8; maxFieldBytes: 65536)
|
||||
post /attachments (UploadReq) returns (AttachmentResp)
|
||||
```
|
||||
|
||||
Logic 直接得到 `*types.UploadReq`，无需维护 Handler。`form` 仍表示 URL query；`multipart` 表示文本表单字段，可用基础类型、文本 scalar 和重复 scalar 数组；`multipartJSON` 是一个严格解码的 JSON 表单字段，可包含对象、数组和已声明的 scalar。
|
||||
|
||||
`File` 提供 `Name`、`ContentType`、`Size`、`Present()` 和 `Open() (io.ReadCloser, error)`。文件名和媒体类型属于客户端元数据，项目继续决定内容检测、存储权限和目标对象名。不要把客户端文件名直接用作存储路径。
|
||||
|
||||
```go
|
||||
reader, err := req.Attachment.Open()
|
||||
if err != nil { return nil, err }
|
||||
defer reader.Close()
|
||||
// 将 reader 传给项目选定的流式存储接口；不要先 io.ReadAll 整个大文件。
|
||||
```
|
||||
|
||||
所有声明字段、重复/未知字段、文件数量和各级限额都会在进入 Logic 前校验。缺少必填项、重复标量/JSON 字段、文件与文本类型混用、畸形 JSON 均失败。JSON 的类型、未知字段和重复 key 检查与普通 JSON 一致。
|
||||
|
||||
默认总量 1 MiB、最多 128 个 part、单文本/JSON 字段 64 KiB；单文件默认受总量约束，文件数组默认最多 16 个。`@body` 可设置 `maxBytes/maxParts/maxFieldBytes/maxFileBytes`；字段上的 `maxBytes/maxFiles` 再收紧对应限额。总量包括 MIME 头和结尾数据；传输编码的 part 被拒绝，避免字节含义不明确。
|
||||
|
||||
文件使用有界复制写入权限为 0600 的临时文件，文本/JSON 字段在各自限额内缓冲。生成 Handler 返回或 panic 时关闭打开的文件 reader 并删除临时文件；不能把请求的 File 留到异步任务使用。失败不会交付半个 DTO，也不会进入 Logic。临时磁盘容量、并发请求上限与 HTTP 超时由部署配置共同约束。
|
||||
|
||||
不声明 multipart 字段时，保留原来的 `body *httpx.Body` 流式入口，不创建临时文件。该方式适合特殊协议；项目应在不可撤销副作用之前完成校验并调用 `body.Complete()`。下载和原始回调继续使用 `@produces` / `@body(mode: raw)`。
|
||||
|
||||
## 完整业务配置的环境覆盖
|
||||
|
||||
生成项目默认执行：代码与 `envDefault` 默认值 → JSON/YAML 文件 → 全结构体环境覆盖 → 既有框架环境别名 → `Validate`。增加业务字段不需要另外写 `os.Getenv`。
|
||||
|
||||
```go
|
||||
type ClientConfig struct {
|
||||
Endpoint string `json:"endpoint" env:"CLIENT_ENDPOINT,required"`
|
||||
Token string `json:"-" env:"CLIENT_TOKEN,required,secret,empty=reject"`
|
||||
Timeout time.Duration `json:"timeout" envDefault:"3s"`
|
||||
Retries []int `json:"retries"`
|
||||
Enabled bool `json:"enabled"`
|
||||
}
|
||||
```
|
||||
|
||||
把字段加入项目 `Config` 后，默认环境名取 `GO_OMNI_` 加 JSON 路径的 UPPER_SNAKE_CASE，如 `GO_OMNI_CLIENT_TIMEOUT`。显式 env 名是完整名称，可以使用自己的业务前缀。`env:"-"` 排除整个子树；`json:"-"` 字段只有显式 env 标签才参与。
|
||||
|
||||
duration 使用 `250ms`、`3s`；slice/map 使用 JSON，如 `[1,3,5]`、`{"retry":"2s"}`。支持嵌套、零/false、空数组、自定义 TextUnmarshaler。空环境值默认允许；可选择 `empty=ignore` 或 `empty=reject`。required 要求字符串非空、指针/集合非 nil；0 和 false 可以是合法业务值，范围由项目 Validate 决定。
|
||||
|
||||
手写项目可使用 `config.LoadProject(path, defaults, config.EnvOptions{Prefix:"MY_APP_"})`，或分别调用 `ApplyDefaults/DecodeFile/OverlayEnv`。读取失败不修改输入默认值；诊断不会打印输入值。不要主动打印含密钥的整个配置，或把底层解析错误展开到公开响应。Validate 不打开日志文件、数据库或存储连接；证书的可读性和握手信任在依赖初始化阶段验证。
|
||||
|
||||
### 一次覆盖完整配置与 HTTP/日志短名称
|
||||
|
||||
```go
|
||||
cfg, err = config.OverlayEnv(cfg, config.EnvOptions{
|
||||
Prefix: "MY_APP_",
|
||||
Empty: "reject", // allow / ignore / reject，项目自行选择
|
||||
Aliases: config.ServerEnvAliases("MY_APP_", "server"),
|
||||
// Lookup 可注入测试或项目配置源；默认 os.LookupEnv。
|
||||
})
|
||||
```
|
||||
|
||||
不要再紧接着调用 `ApplyEnv(cfg.Server, ...)`。上面的调用同时处理完整配置和 HTTP_ADDR、SERVICE、LOG_LEVEL 等框架短名称。例如 `MY_APP_SERVER_ADDRESS` 与 `MY_APP_HTTP_ADDR` 指向同一字段，**完整名称优先**；未设置时才读取短名称。完整名称显式设空仍优先：allow 交给该字段解析（string 可清空；数字等仍要求合法值），ignore 保留文件/默认值，reject 报错。不会因 ignore 再退回别名。字段 `env` 标签的 empty 规则优先于全局规则。
|
||||
|
||||
自定义别名用 `EnvOptions.Aliases`，键是完整环境名、值是按优先级排列的别名数组。两种名称都使用同一 Lookup、空值策略和类型转换；布尔 false、数值 0 与未设置不同。集合始终使用 JSON，包括 `MY_APP_TRUSTED_PROXIES='["127.0.0.1"]'`。
|
||||
|
||||
新项目模板一次调用 OverlayEnv，默认 `Empty: "ignore"`。旧 `ApplyEnv` 保留原有忽略空值、修剪空白及 TRUSTED_PROXIES 逗号列表行为。已有项目的 `internal/config` 属于开发者文件，升级不覆盖它；按上例合并原来的两次覆盖调用后，保留项目自己的 Validate。日志输出的显式完整名称也优先于短名称。
|
||||
|
||||
## 依赖、日志与中间件
|
||||
|
||||
`internal/svc/runtimeGen.go` 持续由生成器维护。项目的 ServiceContext 嵌入 `*lifecycle.Runtime`，只在 `Init(ctx)` 中装配额外依赖：
|
||||
|
||||
```go
|
||||
func (c *ServiceContext) Init(ctx context.Context) error {
|
||||
client, err := NewClient(c.Config.Client)
|
||||
if err != nil { return err }
|
||||
c.Client = client
|
||||
c.OnClose(client.Close)
|
||||
return nil
|
||||
}
|
||||
```
|
||||
|
||||
每个资源初始化成功就登记清理；后续初始化失败自动逆序回滚。正常退出先排空 HTTP 请求，再执行后台组件的 Stop/Drain 阶段，确认收尾后逆序关闭依赖，最后关闭日志。关闭幂等，单个清理函数 panic/返回错误不会跳过其他清理；初始化 panic 清理后继续传播。后台组件按 [分阶段关闭](lifecycle/README.md#后台组件分阶段关闭) 登记；无法确认收尾完成时保留共享依赖并异常退出，不能把取消等同于任务已经结束。
|
||||
|
||||
新项目使用中间件工厂：项目维护 `middleware.Dependencies` 小接口与 `New<Name>(deps) (httpx.Middleware, error)`，svc 提供对应访问器。生成的 runtime 在 Init 成功后自动调用工厂并注册，不再按名字替换 map；工厂失败会释放已经登记的依赖。示例与现有项目迁移步骤见 [中间件工厂](GENERATION.md#中间件工厂自动注册)。
|
||||
|
||||
v0.16 项目及 `omni.gen.json` 中选择 `middleware: handlers` 的项目继续使用原有 `Defaults()`，可以在 Init 设置 `c.Middlewares["RequireAccess"]`。更新时不会重写这部分业务代码；只有显式切换到 factories 后才使用新流程。
|
||||
|
||||
生成入口为每个 App 注入独立 Logger，不修改进程默认 Logger。业务可用 `c.Logger.InfoContext(...)`，或请求链中的 `logx.InfoContext(ctx,...)`。标准库/第三方需要 `*log.Logger` 时使用 `c.Logger.Standard(slog.LevelWarn)`；适配器借用原 Logger，不负责关闭。手写多 App 用 `omni.WithLogInstance(logger)` 显式注入。
|
||||
|
||||
`httpx.Metadata(ctx)` 在业务的标准 context 中提供可信代理规则解析后的 ClientIP、HTTP Method 和路由模板；不放入凭据、完整 URL、查询或 body。业务 userId/tenantId 等仍由项目选择，框架不预设身份模型。
|
||||
|
||||
`middleware.ContextErrors("REQUEST_CANCELED", "REQUEST_TIMEOUT")` 可将原始取消/超时错误映射到项目错误目录；显式 APIError 优先，内部 cause 链保留。状态、业务码与提示仍在项目 Catalog 配置。
|
||||
|
||||
## 字段文档、格式化、Go 错误目录导出
|
||||
|
||||
```text
|
||||
type Item {
|
||||
// 企业名称
|
||||
Name string `json:"name" example:"示例企业"`
|
||||
State int `json:"state,options=0|1" example:"1" enumDescriptions:"[\"禁用\",\"启用\"]"` // 状态
|
||||
}
|
||||
```
|
||||
|
||||
字段前/同行注释同步到 Go 注释和 OpenAPI description。显式 `description` 标签优先；example 的基础字段值也检查类型和约束，枚举说明按声明值顺序填写。字符串 example 直接写内容，其他类型写 JSON。自定义 scalar 的示例不能替代其项目解码器验证；输入输出类型不同时，不把输入示例冒充输出示例。
|
||||
|
||||
```sh
|
||||
go-omni api format --api api/service.api
|
||||
go-omni api format --api api/service.api --check
|
||||
go-omni api generate
|
||||
go-omni api generate --check
|
||||
```
|
||||
|
||||
格式化保留注释、token 和多行字面量，规范四空格缩进、空行、行首尾空白及相邻单行字段的类型/标签/行尾注释对齐；结果幂等。先校验完整契约，check 不写文件；导入的共享目录不被某个服务的格式化命令修改。DTO 按源 `.api` 输出 `dto<Source><摘要>Gen.go`，都属于 `types` 包，跨文件引用无需改包名。
|
||||
|
||||
Go Catalog 是错误的唯一来源时，优先使用 workspace 的显式导出配置，不再维护导出/复制脚本。AppOptions 仍通过 `omni.WithErrors(apierrors.Catalog())` 注册同一个 Go 函数，运行期只注册一次。单个项目也可继续使用 `errors.ExportCatalog` 导出入口目录的 `api/omni.errors.json`；此文件和下面的共享 source 二选一。
|
||||
|
||||
OpenAPI 自动把有收益的重复响应、schema 和示例移到 `components.responses/schemas/examples`，通过标准 `$ref` 引用。HTTP 200 同时含成功和业务失败时保留两种 schema、业务码、模板参数示例和 data:null；业务响应内容不会改变。消费 OpenAPI 的工具需要支持标准本地引用。
|
||||
|
||||
## 两个服务共享契约
|
||||
|
||||
```text
|
||||
workspace/
|
||||
├── contracts/common/response.api
|
||||
├── services/api/api/service.api
|
||||
├── services/api/api/omni.imports.json
|
||||
├── services/id/api/service.api
|
||||
├── services/id/api/omni.imports.json
|
||||
└── omni.workspace.json
|
||||
```
|
||||
|
||||
两个服务的 `omni.imports.json` 可以分别声明：
|
||||
|
||||
```json
|
||||
{"roots":{"common":{"path":"../../../contracts/common","version":"1.0.0"}}}
|
||||
```
|
||||
|
||||
```text
|
||||
import "@common/response.api"
|
||||
```
|
||||
|
||||
只读取入口目录和显式声明的根。保留真实路径检查、symlink 越界拒绝、循环检测、32 层、64 文件、单文件 1 MiB/总量 8 MiB 限额；最多 16 个共享根。不会下载依赖或复制共享定义进服务。移动目录时显式更新 roots。
|
||||
|
||||
`version` 是项目管理的版本标签。生成文档记录每个文件 SHA-256，以及每个共享根所导入文件集合的摘要；可把文档中的 `x-omni-contract-sources.shared.common.sha256` 填入 root 的 `sha256`，固定输入集合，内容变化后必须显式更新。摘要算法是对“该根内相对路径→文件 SHA-256”的键排序 JSON 对象再做 SHA-256，未导入的文件不参与。
|
||||
|
||||
工作区清单：
|
||||
|
||||
```json
|
||||
{"services":[{"dir":"services/api"},{"dir":"services/id"}]}
|
||||
```
|
||||
|
||||
```sh
|
||||
go-omni workspace format --file omni.workspace.json
|
||||
go-omni workspace generate --file omni.workspace.json
|
||||
go-omni workspace check --file omni.workspace.json
|
||||
```
|
||||
|
||||
各服务保持独立 module；可显式填写各服务的 `api`（相对服务目录）和 `module`。所有服务预检通过后再写；每个服务独立提交文件事务，不承诺跨项目的崩溃原子性。check 汇总格式与生成漂移；业务编译/测试仍在各 module 执行。
|
||||
|
||||
### 同一份 Go 错误目录供多个服务生成
|
||||
|
||||
在 workspace 清单显式声明提供目录的 Go 包和函数：
|
||||
|
||||
```json
|
||||
{
|
||||
"errorCatalogs": [{
|
||||
"dir": ".",
|
||||
"package": "example.com/project/internal/apierrors",
|
||||
"function": "Catalog",
|
||||
"output": "contracts/common/errors.json"
|
||||
}],
|
||||
"services": [{"dir":"services/api"}, {"dir":"services/id"}]
|
||||
}
|
||||
```
|
||||
|
||||
`dir` 相对 workspace，必须包含 go.mod；函数签名为 `func Catalog() errors.Catalog`。允许 module 内的 internal 包。先准备 output 的父目录。生成器构建一个临时导出程序，使用 Go overlay、临时 go.mod/go.sum 和 `-mod=readonly`，不会往项目增加导出命令或修改 go.mod/go.sum。最多 16 个提供方，每个有 90 秒构建/执行总时限和 1 MiB stdout 限制。错误消息不回显程序输出。
|
||||
|
||||
只有显式运行 **workspace generate/check** 会执行清单指定的 Go 包及其依赖初始化；不要指向不信任的包。提供目录的函数应只构造目录，不连接数据库、启动服务、写 stdout 或修改项目。框架不扫描其他包，也不通过 shell 执行配置字符串。普通 api validate/export/generate 和 workspace format 只读取现有元数据。
|
||||
|
||||
各服务在自己的 `api/omni.imports.json` 引用共享 JSON：
|
||||
|
||||
```json
|
||||
{
|
||||
"roots": {"common":{"path":"../../../contracts/common","version":"1.0.0"}},
|
||||
"errors": {
|
||||
"source": "@common/errors.json",
|
||||
"include": ["USERNAME_INVALID", "INTERNAL_ERROR"],
|
||||
"routes": {"GET /permissions":["INTERNAL_ERROR"]}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
`include` 省略或 null 表示全部目录，`[]` 表示不列业务错误；routes 按 **大写方法 + 空格 + .api 原路径**（如 `GET /users/:id`）覆盖服务级列表。错误标识、路由拼错或重复标识会明确报错。路由已经通过 `.api @errors` 声明独立运行期目录时，不能再给它设置文档 routes 列表。
|
||||
|
||||
**这些列表只决定文档展示，不修改 App 错误目录、路由继承或运行期可返回的错误。** `.api` 不需要重复定义 Go 错误表。状态、业务码、提示和模板参数仍来自同一 Catalog；特殊自定义 Encoder 的文档由项目显式扩展。
|
||||
|
||||
```sh
|
||||
# 首次生成导出一次共享目录，所有服务预检通过才写入
|
||||
# 共享 JSON 不复制到各服务；已有 api/omni.errors.json 请显式移除后改用 source。
|
||||
go-omni workspace generate --file omni.workspace.json
|
||||
go-omni workspace format --file omni.workspace.json
|
||||
go-omni workspace generate --file omni.workspace.json
|
||||
go-omni workspace check --file omni.workspace.json
|
||||
```
|
||||
|
||||
共享 JSON 应纳入版本控制。check 在内存重新导出并比较 JSON，然后检查所有服务；缺失或过期时失败，不更新项目文件。Go 构建缓存仍可能更新；显式提供方的自有副作用不属于生成器可隔离范围。业务 CI 仍执行各 module 的编译与测试。目录函数本身有变化时重新 generate，受控共享根的固定 SHA256 如需改变仍由项目显式更新。
|
||||
|
||||
## v0.13 项目升级
|
||||
|
||||
先使用与目标框架匹配的 CLI；CLI 会提示与 go.mod 不同的版本。当前生成模板至少需要 v0.18.0-preview（或显式引用当前源码）。
|
||||
|
||||
```sh
|
||||
go-omni api upgrade --dir . --dry-run
|
||||
go-omni api upgrade --dir . --preview .goOmni/upgradePreview
|
||||
# 只有标为 safe 的原始模板才会自动替换；review 阻止全部写入。
|
||||
go-omni api upgrade --dir . --apply
|
||||
go mod tidy
|
||||
go-omni api generate --check
|
||||
go test ./...
|
||||
go build .
|
||||
```
|
||||
|
||||
自动迁移只替换与 v0.13 原始模板一致的配置/svc 基础文件、移除原始 close.go，并更新最低依赖及生成产物；保留 Logic、Repository、AppOptions、独立命令。迁移失败回滚已改的项目文件。存在业务修改时，仅输出这些基础文件的候选版本和清单，不生成整棵业务代码让人重新拼接。
|
||||
|
||||
定制项目按预览定点迁移：保留依赖字段，把初始化移到 Init，嵌入 Runtime，清理改为 OnClose 登记；移除旧 New/Close/OnClose；合并业务配置和结构化 MySQL 配置，更新 go.mod，再正常 generate。生成器会拒绝遗留构造/关闭实现，避免重复函数或悄悄绕过清理。v0.12 及更早的定制结构不能被精确自动合并，使用同一预览逐项迁移并编译验证。

# 公共字段、结构映射与生成选项
|
||||
|
||||
本页对应 `v0.18.0-preview`。CLI 与框架依赖固定到同一版本：
|
||||
|
||||
```sh
|
||||
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.18.0-preview
|
||||
# 已有业务项目内执行：
|
||||
go get git.yuntuo.hk/k2safe/go-omni@v0.18.0-preview
|
||||
```
|
||||
|
||||
私有仓库访问设置见 [安装说明](README.md#准备环境与安装)。升级不会覆盖业务文件；已有中间件保持 handlers 模式，切换工厂模式按本页迁移步骤完成。
|
||||
|
||||
## 一份项目生成配置
|
||||
|
||||
新项目根目录生成开发者维护的 `omni.gen.json`：
|
||||
|
||||
```json
|
||||
{
|
||||
"repository": "none",
|
||||
"middleware": "factories"
|
||||
}
|
||||
```
|
||||
|
||||
该文件与 `.api` 一起提交。每次 `api generate`、`--check`、`--dry-run` 和 `workspace generate/check` 都会读取；`api validate/export/format` 只处理契约，不加载业务 Go 类型。
|
||||
|
||||
- `repository: none` 是默认值，不创建空 Repository 文件。`group` 按 `.api` 的 group 补齐 `internal/repository/<group>/repository.go`；文件始终属于业务。切回 none 后不再补骨架，已有文件不删除、不覆盖。实际 SQL、ORM 和仓储划分由项目决定。
|
||||
- `middleware: factories` 是新项目默认值，按下文自动初始化。`handlers` 保留原有 `Defaults()` 与 `func(next Handler) Handler` 接口，供既有项目逐步迁移。
|
||||
- `mappings` 可省略；只有明确列出的类型对才生成映射。未启用时不会运行 Go 类型加载命令，也不增加运行时依赖。
|
||||
- 升级首次遇到没有配置的旧 manifest 时，补一份 `middleware: handlers` 的配置，保留原有手写注册；Repository 默认 none。生成配置建立后不能直接删除，否则生成失败，避免误关闭映射或改变中间件模式。
|
||||
|
||||
### 按模块拆分映射（v0.18 新增）
|
||||
|
||||
主配置可以保留少量内联 `mappings`，也可以只列出文件：
|
||||
|
||||
```json
|
||||
{
|
||||
"repository": "none",
|
||||
"middleware": "factories",
|
||||
"mappingFiles": ["mappings/requests.json", "mappings/responses.json"]
|
||||
}
|
||||
```
|
||||
|
||||
每个子文件只包含 `{"mappings": [...]}`，其中每条映射的写法与原来一致。先加载主配置内联定义，再按文件列表顺序加载；所有定义合并后统一校验，可以跨文件、向前引用 `mapping`。输出按映射名排序，文件拆分不改变函数名或语义。
|
||||
|
||||
- 路径相对项目根目录，必须是明确列出的 `.json` 文件。不展开通配符，不允许越界路径、符号链接、重复文件或多层导入；子文件不能覆盖 repository/middleware 等项目选项。
|
||||
- 重名映射、指针辅助函数名冲突、未知映射与循环引用明确报错；文件之间不能用覆盖顺序隐藏冲突。重复定义会指出两个来源文件，字段生成错误也带来源文件。
|
||||
- 文件均由项目维护，重新生成不改写它们。原来的单文件 `mappings` 继续有效。迁移时将完整条目移到子文件并删除原位置，不能复制后保留两份同名定义。
|
||||
- 最多 64 个子文件、单文件 1 MiB、全部配置 4 MiB；合计仍最多 128 个映射。主配置和子文件一起提交 Git。
|
||||
- `api generate`、`--check`、`--dry-run` 与 `workspace generate/check` 使用同一加载逻辑。缺少子文件或不完整配置立即失败，check/预览不写入；生成期间重新核对所有配置输入，发生变化时要求重试。
|
||||
|
||||
## 公共字段组合
|
||||
|
||||
```text
|
||||
type EmployeeFields {
|
||||
// 员工姓名。
|
||||
Name string `json:"name" binding:"max=80"`
|
||||
Salary Money `json:"salary"`
|
||||
}
|
||||
|
||||
type EnterpriseRequest {
|
||||
EmployeeFields
|
||||
}
|
||||
|
||||
type AdminRequest {
|
||||
EmployeeFields
|
||||
CompanyID string `path:"companyId"`
|
||||
}
|
||||
```
|
||||
|
||||
`Money` 由项目按既有 scalar 语法声明。组合行只有已声明的对象类型名，不加指针或字段 tag。公共对象可以通过已有相对 import 或声明过的共享根 `@common/...` 引入。
|
||||
|
||||
生成器展开为普通 Go 字段。JSON 保持平铺；字段的绑定来源、校验、注释、可空性和 OpenAPI 使用同一份展开结果。不会在 JSON 中增加 `EmployeeFields` 一层。重复 Go 字段、重复来源字段名、循环组合、未知对象和过深展开均失败；即使重复字段类型相同，也不能隐式覆盖。要改变某个字段的规则，应拆出更小的公共组合。
|
||||
|
||||
允许多层组合，上限 32 层、单类型 4096 字段、全契约展开 65536 字段。Go 匿名指针嵌入并非本功能；生成 DTO 中不会使用匿名嵌入。
|
||||
|
||||
## 可选结构映射
|
||||
|
||||
`.api` 生成 DTO，业务独立维护输入/结果类型。项目明确选择需要自动赋值的类型对；不从数据库反向生成公开接口，不自动推断反向映射。
|
||||
|
||||
假设 `types.AdminRequest` 有 `Name string`、`Salary amount.Money`、`CompanyID string`，业务的 `domain.EmployeeInput` 有 `EmployeeName string` 和同类型 `Salary`：
|
||||
|
||||
```json
|
||||
{
|
||||
"repository": "none",
|
||||
"middleware": "factories",
|
||||
"mappings": [
|
||||
{
|
||||
"name": "ToEmployeeInput",
|
||||
"source": {"package": "example.com/payroll/internal/types", "type": "AdminRequest"},
|
||||
"target": {"package": "example.com/payroll/internal/domain", "type": "EmployeeInput"},
|
||||
"fields": {
|
||||
"EmployeeName": {"source": "Name"}
|
||||
},
|
||||
"ignoreSource": {
|
||||
"CompanyID": "由 Logic 单独做企业范围授权，不属于请求体输入"
|
||||
}
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
执行 `go-omni api generate` 后，产生独立的生成文件 `internal/mapping/mappingsGen.go`：
|
||||
|
||||
```go
|
||||
func ToEmployeeInput(source types.AdminRequest) (domain.EmployeeInput, error) {
|
||||
var result domain.EmployeeInput
|
||||
result.EmployeeName = source.Name
|
||||
result.Salary = source.Salary
|
||||
return result, nil
|
||||
}
|
||||
```
|
||||
|
||||
包别名由生成器决定。业务调用 `mapping.ToEmployeeInput(*req)`；反向响应映射按另一条 source/target 规则声明。两个类型完全相同时通常无需映射。
|
||||
|
||||
### 类型与覆盖检查
|
||||
|
||||
自动赋值要求同名且 **Go 类型一致**（类型别名按 Go 类型系统处理），字段名使用 Go 名称，不按 JSON 标签猜对应关系。int32 → int64、`*Money` → Money、数值 ID → string 都必须显式转换。不会暗中补零、解引用或执行数字强转。
|
||||
|
||||
每个源字段必须被使用或出现在 `ignoreSource`；每个目标字段必须被赋值或出现在 `ignoreTarget`。忽略规则必须给出非空原因，目标忽略明确意味着保留零值；规则引用不存在的字段也会失败。新字段若无法自动匹配，会在生成阶段报错。两边同时添加的同名同类型字段会自动加入生成代码，`--check` 检出未重新生成的差异。
|
||||
|
||||
根类型是项目可导入的具名结构；支持值类型匿名嵌入，规则可用 `Employee.EmployeeName` 这样的实际 Go 字段路径。同名提升歧义、未导出字段和匿名指针嵌入拒绝处理。普通具名嵌套字段使用独立映射或转换函数，不猜测内部结构。泛型声明不能直接作为根；具体字段类型按 Go 类型系统检查。
|
||||
|
||||
配置变化、遗漏映射、类型错误会在写入前失败。映射生成与其他生成产物使用同一套文件所有权机制；手改映射生成文件会被拒绝覆盖。
|
||||
|
||||
### 显式转换函数
|
||||
|
||||
```json
|
||||
"fields": {
|
||||
"Salary": {
|
||||
"source": "Salary",
|
||||
"convert": {"package": "example.com/payroll/internal/convert", "name": "SalaryValue"}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
支持这两种精确签名：
|
||||
|
||||
```go
|
||||
func SalaryValue(source *amount.Money) amount.Money
|
||||
func SalaryValue(source *amount.Money) (amount.Money, error)
|
||||
```
|
||||
|
||||
项目选择一种实现。nil、默认值、金额精度、日期格式和错误码由函数负责；若两边已经是同一个 Money 类型，无需再次解析或序列化。转换函数应仅负责值转换，不执行 SQL 或改变授权范围。
|
||||
|
||||
错误通过 `%w` 加上映射名/目标字段路径，保留 `errors.Is/As` 和框架错误链；返回零目标值，不交付部分完成的结果。包装不主动添加源值或转换后的值。错误是否公开仍由项目错误目录和响应策略决定。
|
||||
|
||||
### 嵌套对象、数组与引用
|
||||
|
||||
`mapping` 指向同配置中的另一条映射，`elements` 明确要求逐项映射：
|
||||
|
||||
```json
|
||||
"fields": {
|
||||
"Summary": {"source": "Summary", "mapping": "ToSummary"},
|
||||
"Items": {"source": "Items", "mapping": "ToItem", "elements": true}
|
||||
}
|
||||
```
|
||||
|
||||
`mapping` 与 `convert` 互斥。`elements` 可以配合其中任意一种，也可以对类型相同的元素直接赋值；支持 slice→slice、等长 array→array，禁止隐式互转。nil slice 保持 nil，非 nil 空 slice 保持非 nil，逐项失败的错误包含索引，循环映射声明被拒绝。
|
||||
|
||||
未选择 elements 的同类型指针、map、slice 使用普通 Go 赋值，**共享引用**，不做隐式深拷贝。elements 会分配新的目标 slice，但元素内的引用仍遵循其映射规则。需要深拷贝时显式提供转换函数。
|
||||
|
||||
映射不保存原 JSON 的字段存在信息。普通 `*T` 在绑定后可能已把缺失和 null 合并为 nil；无法在转换阶段恢复区分。有三态需要的项目必须先使用能携带该信息的输入类型及绑定扩展；没有声明三态时，保持当前输入类型的语义。完整表单更新和局部更新由业务决定，框架不把 nil 自动解释成“保留旧值”。
|
||||
|
||||
### 可空嵌套映射与显式 nil 策略（v0.18 新增）
|
||||
|
||||
假设已有 `ToChild` 定义 `types.Child → domain.Child`。父对象的字段规则可以直接复用它：
|
||||
|
||||
```json
|
||||
"fields": {
|
||||
"Child": {"source": "Child", "mapping": "ToChild"},
|
||||
"Children": {"source": "Children", "mapping": "ToChild", "elements": true}
|
||||
}
|
||||
```
|
||||
|
||||
| 源字段 → 目标字段 | 明确选择 mapping 后的行为 |
|
||||
| --- | --- |
|
||||
| `S → T` | 调用原值映射 |
|
||||
| `*S → *T` | 默认保留 nil；非 nil 调用值映射，并分配新的目标对象；也可配置 `nil: "error"` 拒绝 nil |
|
||||
| `S → *T` | 调用值映射，成功后返回目标对象指针 |
|
||||
| `*S → T` | 必须选择 `nil: "zero"` 或 `nil: "error"`，不猜默认值 |
|
||||
|
||||
`nil: "preserve"` 只适用于可空源和可空目标。`nil: "zero"` 只适用于可空源和非空目标：nil 直接产生目标 Go 零值，**不调用子映射或转换函数**。`nil: "error"` 在 nil 时返回带映射/字段路径的普通转换错误，HTTP 公开响应仍由项目的错误处理策略决定；需要领域错误码时使用项目 converter。
|
||||
|
||||
同一规则适用于显式 `elements: true` 下的 slice/等长数组元素，包括 `[]*S → []*T`。nil slice、非 nil 空 slice、nil 元素分别保留；元素失败保留索引与内部错误链，整个映射返回零目标值，不交付部分结果。只支持这里列出的单层指针，不自动处理多层指针或递归对象图。
|
||||
|
||||
普通同类型指针字段未指定 mapping 时仍直接赋值、共享引用；上述显式映射会创建目标子对象，但不承诺对其中所有引用深拷贝。业务不可变快照继续由项目设计。
|
||||
|
||||
简单的 `*T → T` 也可以单独指定 nil 策略，减少重复解引用函数：
|
||||
|
||||
```json
|
||||
"fields": {
|
||||
"Title": {"source": "Title", "nil": "zero"},
|
||||
"Count": {"source": "Count", "nil": "error"}
|
||||
}
|
||||
```
|
||||
|
||||
这里必须是完全相同的 Go 元素类型，`*int32 → int64`、枚举 → string、数字编号 → string 仍需显式 converter。非 nil 的零值正常保留。`convert` 与 `nil` 不能同时设置，现有 converter 继续完整控制自己的空值、格式和错误语义。
|
||||
|
||||
### 可选指针返回辅助（v0.18 新增）
|
||||
|
||||
在映射条目上增加 `"pointerResult": true`，生成器保留 `ToResponse(source S) (T, error)`，另加：
|
||||
|
||||
```go
|
||||
func ToResponsePtr(source S) (*T, error)
|
||||
```
|
||||
|
||||
Logic 在业务调用成功后可直接写 `return mapping.ToResponsePtr(result)`。转换失败时返回 `nil, err`，错误链不变；成功才返回非 nil 指针。业务调用本身的错误仍由 Logic 处理，辅助函数不执行任何业务操作。
|
||||
|
||||
辅助函数名称固定为映射名加 `Ptr`，与其他映射/辅助函数同名会在生成前报错。输入仍是原来的值类型 S，不用 nil 输入表达业务错误；关闭该选项会移除辅助函数，使用它的业务代码需同时调整。
|
||||
|
||||
### 生成顺序与 CI
|
||||
|
||||
1. 先从 `.api` 生成项目，添加业务结构、scalar 和转换函数，执行 `go mod tidy`。
|
||||
2. 在 `omni.gen.json` 列出映射，执行 `go-omni api generate`。
|
||||
3. Logic 调用生成函数。后续改字段后重复生成，不修改 `*Gen.go`。
|
||||
4. CI 同时运行 `go-omni api generate --check` 与 `go test ./...`。
|
||||
|
||||
启用映射后，CLI 通过 `go list -deps -export` 加载明确声明的包与依赖，按当前构建环境做类型检查，不执行业务代码、init 或转换函数。采用待生成 DTO 的临时 overlay，避免“新增字段还看旧 DTO”。go.mod/go.sum 的副本及 overlay 都在临时目录，check 不修改项目文件；Go 自己的构建/模块缓存可能更新。使用当前 GOOS/GOARCH/GOFLAGS、`GOWORK=off`；依赖用 go.mod 与 replace 表达，生成超时为 90 秒。
|
||||
|
||||
类型包/转换函数包不能依赖输出包 `internal/mapping`；把转换函数放在独立包中，避免导入环。若包本身无法编译，先运行 `go list -deps -export <相关包>` 排查；CLI 不回显可能含私有仓库凭据的 Go 下载输出。纯值字段转换只生成标准 Go 代码，不引入运行时反射搬运、JSON 往返、ORM 或队列依赖。
|
||||
|
||||
## 中间件工厂自动注册
|
||||
|
||||
`.api` 沿用 `middleware: RequireAccess` 或 auth 对应的中间件声明。新项目会生成可编辑的 `internal/middleware/requireAccessFactory.go`，只需实现一次：
|
||||
|
||||
```go
|
||||
// internal/middleware/dependencies.go，由项目维护。
|
||||
type AccessChecker interface {
|
||||
CheckAccess(context.Context, string) error
|
||||
}
|
||||
type Dependencies interface {
|
||||
AccessChecker() AccessChecker
|
||||
}
|
||||
|
||||
// internal/middleware/requireAccessFactory.go，由项目维护。
|
||||
func NewRequireAccess(deps Dependencies) (httpx.Middleware, error) {
|
||||
checker := deps.AccessChecker()
|
||||
if checker == nil { return nil, errors.New("access checker is required") }
|
||||
return func(next httpx.Handler) httpx.Handler {
|
||||
return func(c *httpx.Context) error {
|
||||
if err := checker.CheckAccess(c.Context(), c.Header("Authorization")); err != nil {
|
||||
return err
|
||||
}
|
||||
return next(c)
|
||||
}
|
||||
}, nil
|
||||
}
|
||||
|
||||
// internal/svc/access.go，由项目维护；ServiceContext.Init 初始化 c.Auth。
|
||||
func (c *ServiceContext) AccessChecker() middleware.AccessChecker { return c.Auth }
|
||||
```
|
||||
|
||||
编译器检查 ServiceContext 是否实现依赖接口，middleware 不导入 svc。多个工厂可以共用这些小接口。所需 imports 和具体鉴权服务仍属于项目。
|
||||
|
||||
启动顺序为：框架基础依赖 → `svc.Init` → 生成的 `middleware.New(c)` 调用各具名工厂 → 创建 App/注册路由 → 监听。中间件实例创建一次，由请求并发复用；不要把单次请求信息存在实例字段里。工厂之间没有初始化顺序依赖；路由执行顺序仍以 `.api` 声明为准。
|
||||
|
||||
工厂返回错误或 nil 中间件均阻止监听；错误链保留，已登记资源按现有生命周期清理。工厂 panic 也先清理依赖再传播。资源初始化和清理登记放在 svc.Init，工厂借用资源；HTTP 请求排空之前不会关闭这些依赖。
|
||||
|
||||
factory 模式不再在 Init 写 `Middlewares["..."]`；残留非空手写注册表会明确报错，防止生成注册静默覆盖它。未实现的工厂让启动失败；未实现的 Logic 仍返回 501。
|
||||
|
||||
### 既有项目迁移
|
||||
|
||||
1. 首次更新保持 `middleware: handlers`，现有 hook 和手写 Configure 不变。
|
||||
2. 改为 factories 并重新生成，会补 `dependencies.go` 和 `*Factory.go`，保留原来的手写文件。
|
||||
3. 将旧实现迁入工厂，提供 Dependencies 的访问器；移除 Init 中按名字覆盖 map 的代码。
|
||||
4. 旧函数不再需要时由项目删除。若新工厂符号与旧文件中的同名函数冲突，整理旧文件；生成器不覆盖业务代码。
|
||||
5. `generate --check` 与 `go test ./...` 检查后再运行。工厂没有全部实现前，服务不会启动。
|
||||
|
||||

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。
|
||||
|
||||
本版新增生成选项、公共字段组合和映射，详见 [生成能力指南](GENERATION.md)。
|
||||
|
||||
## 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/databaseOptions.go` | 可选 MySQL 驱动与项目启动检查扩展 |
|
||||
| `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；默认不补空骨架，可选 group 模式 |
|
||||
| `internal/middleware/*Factory.go`、`dependencies.go` | 中间件工厂与依赖小接口，svc 实现访问器 |
|
||||
| `omni.gen.json`、映射转换函数（支持 `mappingFiles` 引用子文件） | 生成选项、显式类型对与差异规则 |
|
||||
| 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：`internal/svc/runtimeGen.go`、`main.go`、`internal/handler/*Gen.go`、分组的 `handlersGen.go`、`internal/types/*Gen.go`、可选映射 `internal/mapping/mappingsGen.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。New 本身由生成器维护；新增客户端时扩展配置和 svc 的 `Init(ctx) error`：
|
||||
|
||||
```go
|
||||
client, err := newClient(c.Config.Client)
|
||||
if err != nil { return 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
|
||||
```
|
||||
|
||||
ServiceContext 嵌入 `*lifecycle.Runtime`；框架维护锁、清理栈和失败回滚，项目不再复制 Close/OnClose 实现。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。普通 `.api` 编译不执行 Go；可在 workspace 显式配置 Catalog 函数，统一导出共享文档元数据，也可沿用 `api/omni.errors.json`，详见 [元数据导出](DEVELOPMENT.md#字段文档格式化go-错误目录导出)。
|
||||
|
||||
`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，使用 WorkContext 并登记成对的 OnStop/OnDrain，详见 [分阶段关闭](lifecycle/README.md#后台组件分阶段关闭)。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。后台监控任务应通过 OnStop/OnDrain 停止并等待，再进入资源清理；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。
|
||||
|
||||
<a id="从-v012-生成项目升级"></a>
|
||||
|
||||
## 从 v0.13 或更早版本升级
|
||||
|
||||
请按 [v0.14 定点迁移说明](DEVELOPMENT.md#v013-项目升级) 使用 `api upgrade`。原始模板可以自动升级；含业务修改的基础文件必须参考局部预览合并。旧 New/Close/OnClose 移到框架 Runtime，项目依赖初始化保留在 Init。不要继续向项目里复制生命周期锁和清理栈。
|
||||
|
||||
## 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)
|
||||
```
|
||||
|
||||
- 以下为未声明 multipart 字段的流式用法；声明式绑定见 [上传字段](DEVELOPMENT.md#声明式-multipart)。raw/流式 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 v0.18.0-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。

### 数据库、存储及其他模块

依赖在启动入口或项目自己的 `internal/servicecontext` 中创建，通过构造函数传给 Service/Repository，避免每个请求都新建连接池。只注册自己拥有的资源，例如 `app.OnShutdown(db.Close)`；关闭按注册的逆序执行。
|
||||
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)。

|
||||
- `mappingFiles` 显式引用项目内的映射文件，支持跨文件向前引用；统一检查重名、循环、类型与字段覆盖。禁止多层导入、路径越界和隐式覆盖，生成期间核对全部配置输入。
|
||||
- 同类型 `*T → T` 可显式配置 nil zero/error；现有 converter 保持完整控制，不默认放宽类型或混入领域规则。
|
||||
- `pointerResult: true` 额外生成 `<Name>Ptr(S) (*T,error)`，原值函数保留；失败返回 nil 与原错误，辅助函数名冲突在生成前拒绝。

|
||||
v0.17 的单文件 mappings、现有 converter 和业务文件继续保留。配置拆分时移动完整映射条目，主配置显式列出子文件；不保留重复定义。新能力均为可选生成配置，不增加运行时依赖。nil zero 表示 Go 零值并跳过子映射；业务必填、金额精度、编号格式和快照复制仍由项目负责。

## 接入

使用与迁移见 [生成能力指南](GENERATION.md)，回归和发布后验收见 [验收记录](reports/nullableMappingAcceptance.md)。本版仍为 preview。
|
||||
|
||||
- 手写项目：`omni.New(omni.WithErrors(catalog), omni.WithResponse(responseConfig))`，业务返回 `omnierrors.ByCode(key)`，按需 `.WithCause(err)`。
|
||||
- 契约项目：`.api errorCatalog` 定义一次，路由 `@errors` 或 `@server errors` 引用，生成 `apierrors.UsernameInvalid()` 等函数、Catalog、路由策略及 OpenAPI。
|
||||
- 项目目录的 `defaultStatus` 可以设为 200，单条错误可设置 403、409 等；默认只作用于目录条目，不改变未配置系统错误的兜底。
|
||||
- 逻辑标识必须唯一，对外业务码可以重复，支持字符串/int32/int64；整数精度与所选响应类型在加载/编译时校验。
|
||||
- HTTP 200 失败使用错误响应模板，OpenAPI 的 200 使用 anyOf 保留成功 DTO 和错误体；同码错误保留不同示例。
|
||||
- App 和路由目录隔离、初始化复制；每次生成/解析错误都返回独立对象。未知标识转系统兜底，默认公开响应不暴露 cause。

## 配置边界
|
||||
减少项目里的重复声明、字段赋值和中间件装配代码，业务规则继续由项目控制：
|
||||
|
||||
生成路由的目录和响应以 `.api` 为准，优先于 App 默认配置；ByCode 需要当前目录中存在该标识。使用生成函数后仍须声明实际路由的 @errors，保持文档准确。不同路由可使用不同码类型与返回格式。
|
||||
- `.api` 公共字段组合：保持 JSON 平铺，DTO、绑定、校验和 OpenAPI 同步；字段冲突、循环和超限明确报错。
|
||||
- 可选结构映射：在 `omni.gen.json` 显式声明源与目标，生成编译期检查的普通 Go 赋值。不同字段名、金额、时间和指针转换由项目指定函数；遗漏字段与类型错误在写文件前失败。不使用 JSON 往返或运行时反射。
|
||||
- 带依赖的中间件工厂：svc 初始化依赖后自动调用 `New<Name>(deps)` 并注册；错误、nil 或 panic 阻止启动，已登记资源按生命周期清理。
|
||||
- Repository 骨架默认关闭，可按 group 启用；已有业务文件始终保留。生成选项与映射纳入重新生成和 `--check`。
|
||||
|
||||
目录与响应模板分开，自定义 Encoder 继续控制最终 HTTP 状态和文本/XML 等协议。直接输出与已提交响应不会被再次包装。旧同标识 Codes/Messages 若与新目录冲突会明确拒绝。
|
||||
```sh
|
||||
go get git.yuntuo.hk/k2safe/go-omni@v0.17.0-preview

|
||||
|
||||
访问日志记录实际提交状态，并带 failed/errorKey/可用的 businessCode。指标与链路识别 HTTP 200 业务失败；标准中间件和本地/共享幂等重放保留错误标识，旧缓存缺少标记时不补推历史状态。业务代码中的散落提示仍需业务项目按目录逐步迁移；本轮没有改写 eTax/ePay 业务逻辑。

||||
新项目默认使用 factories；已有项目首次升级保留 handlers 模式，需要显式迁移后再切换。映射按需开启，先准备业务类型、转换函数和依赖，再声明映射；普通引用赋值保留 Go 语义，缺失/null 语义由项目类型与转换函数定义。
|
||||
|
||||
## 验证入口
|
||||
使用方法、文件归属和升级步骤见 [生成能力指南](GENERATION.md)，回归与发布验收见 [验收记录](reports/generationExperienceAcceptance.md)。本版仍为 preview；框架验收不等于业务项目完成迁移。
|
||||
|
||||
全量 44 个测试包的 race、vet、build 和实际进程验收通过；发布后的空缓存远程 CLI 与 7 组生成消费者回归也通过，同版依赖且无本地 replace。标签固定在 `8b588a24cd653dac77dd68f6777e0db367981f19`。

# v0.16.0-preview（历史版本）
|
||||
|
||||
补齐通用契约与生成体验，业务响应协议继续由项目定义：
|
||||
|
||||
- `returns([]string/[]int64/[]bool/[]any)` 及其他支持的基础类型数组，贯通 Logic、Handler、OpenAPI 和生成检查。nil 根数组输出 `[]`；DTO 数组、nullable、null、raw 和 204 保持原语义。字节数组明确拒绝 base64/数组歧义。
|
||||
- OpenAPI 以标准 components / `$ref` 共享重复响应、schema、示例；保留同一 HTTP 200 下的成功与失败、模板参数、数字业务码和 data:null。
|
||||
- workspace 显式配置 Go Catalog 提供方，一次导出共享 JSON，多服务通过受控根引用。支持服务/路由的文档错误列表，运行期 App 目录继承不变。check 核对导出漂移并保持项目文件不变。
|
||||
- EnvOptions.Aliases + ServerEnvAliases 统一完整配置与框架短名称的 Lookup、类型转换、空值规则。完整名称优先，显式空值不等于未设置；旧 ApplyEnv 的空值/逗号列表行为保留。
|
||||
|
||||
```sh
|
||||
go get git.yuntuo.hk/k2safe/go-omni@v0.16.0-preview
|
||||
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.16.0-preview
|
||||
go-omni api generate
|
||||
go-omni api generate --check
|
||||
go test ./...
|
||||
```
|
||||
|
||||
旧项目 config/Logic/svc 继续由开发者维护，不会被重新生成覆盖。已有环境配置需按 [一次覆盖完整配置](DEVELOPMENT.md#一次覆盖完整配置与-http日志短名称) 合并 OverlayEnv 与 ApplyEnv；共享错误目录接入见 [workspace 配置](DEVELOPMENT.md#同一份-go-错误目录供多个服务生成)。已有手写权限 Handler 切换自动生成前，先迁出实现并显式移除 Manual 文件，生成器不会静默删除。
|
||||
|
||||
全量 race（含实际生成消费者）、vet、build、根入口/退出/再生成验证通过。eTax 只读契约验收：API 文档 20,751,149 → 847,171 字节，ID 文档 1,008,210 → 392,481 字节；70 个操作展开引用后与原文档完全一致。空缓存远程 CLI / 固定版本消费者验收也已通过，没有本地 replace；标签固定在 `64e3bd6cfced225476d58e95037249cd0a4fe695`。详见 [验收记录](reports/contractFollowupAcceptance.md)。这不代表已完成业务项目迁移。
|
||||
|
||||
---
|
||||
|
||||
# v0.15.0-preview（历史版本）
|
||||
|
||||
增加通用后台分阶段关闭：生成入口先完成 HTTP 排空，再运行全部 OnStop、全部 OnDrain，确认组件收尾后逆序释放 OnClose 资源，最后关闭日志。适用于任意后台组件；不引入 Orbit，不改变业务事务或任务一致性策略。
|
||||
|
||||
- svc 登记成对、同名的 OnStop/OnDrain，Context 用于早期退出通知，WorkContext 供已接受工作在收尾期间使用。同一阶段并发执行，存在内部先后依赖的组件组合登记。
|
||||
- server.lifecycle 配置 stopTimeout、drainTimeout、cancelTimeout。阶段超时取消工作并给未返回钩子收尾窗口；错误与阶段/组件名称可通过错误链追踪。
|
||||
- 不能确认后台已经结束时，返回 ErrResourcesRetained，保留共享资源和借用日志，生成进程非零退出。未返回的 Stop 不会与自己的 Drain 重叠；错误、panic 不阻止其他组件尝试收尾。
|
||||
- task.Runner 增加 StopAccepting/Wait，原 Shutdown/Close 继续可用。核心 lifecycle 不依赖 task 或其他适配器。
|
||||
- 初始化和监听失败复用同一流程；重复关闭只执行一次。生成器继续保留配置、svc 和业务代码。
|
||||
|
||||
```sh
|
||||
go get git.yuntuo.hk/k2safe/go-omni@v0.15.0-preview
|
||||
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.15.0-preview
|
||||
go-omni api generate
|
||||
go-omni api generate --check
|
||||
go test ./...
|
||||
```
|
||||
|
||||
v0.14.x 无需重写 svc/config；生成器更新 main/runtimeGen，未配置时使用默认时限。也可 api upgrade --dry-run/--apply 更新依赖与生成文件，保留已有项目扩展。需要阶段保证的旧后台 OnClose 登记，应显式迁到 Stop/Drain；v0.13 及更早版本仍按原迁移指南处理。
|
||||
|
||||
全量 race（含实际生成项目）、vet、build 和隔离 MySQL/GORM 验收已通过。发布后的空缓存远程生成项目与真实 MySQL/GORM 验收也通过，CLI/框架同版且无本地 replace；标签固定在 `16deead70e860052c5b629511207578c03f9b2cb`。详见 [生命周期接入](lifecycle/README.md#后台组件分阶段关闭) 与 [验收记录](reports/phasedLifecycleAcceptance.md)。Go 无法强制结束任意 goroutine；OnClose 仍须能返回，HTTP 处理器仍须响应取消。此版不会将未知的第三方组件自动改造成优雅关闭组件。
|
||||
|
||||
---
|
||||
|
||||
# v0.14.1-preview（历史版本）
|
||||
|
||||
增加可选 `database/gormx`：GORM 复用 go-omni 已初始化的标准池、TLS、限额、健康检查和关闭流程，业务继续使用原生 GORM 模型与事务。核心 App/数据库包的编译依赖链不引入 GORM。
|
||||
|
||||
在 svc.Init 中调用 `gormx.MySQL(ctx, c.DB, gormx.WithLogger(c.Logger))`；通用 Open 工厂保留其他方言入口。适配器保护借用池不被初始化失败路径关闭，并为初始化查询设置时限。查询使用 WithContext，SQL 日志接入 logx，请求标识、慢查询和错误分类贯通；默认不输出绑定参数与驱动完整错误文本。
|
||||
|
||||
v0.14.0 项目更新 module 与 CLI 即可，不改生成目录或 main。模板最低运行时保持 v0.14.0；修正新版 CLI 把最低兼容版本误当自身版本、导致同版消费者出现版本提示的问题。其他数据库方言和管理额外池的插件未纳入本次实库验收，原生 PrepareStmt 的生命周期限制见 [接入说明](database/gormx/README.md)。
|
||||
|
||||
```sh
|
||||
go get git.yuntuo.hk/k2safe/go-omni@v0.14.1-preview
|
||||
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.14.1-preview
|
||||
```
|
||||
|
||||
全量 race（含生成消费者）、vet、build，以及隔离 MySQL 的事务/取消/日志/生成项目接入通过。发布后的空缓存远程 MySQL/GORM 和生成项目验收均通过，无本地 replace，CLI 与框架使用同版。标签固定在 `b8ab6b35219d53d6de392c920fe7ecbe9a76dade`，详见 [GORM 验收](reports/gormAcceptance.md)。

# v0.14.0-preview（历史版本）
|
||||
|
||||
本版补齐契约驱动的业务开发与通用基础设施。项目继续维护接口、配置、依赖装配、Logic、SQL 和业务规则；生成器维护入口、请求绑定、路由、响应与文档。
|
||||
|
||||
## 安装与升级
|
||||
|
||||
```sh
|
||||
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.14.0-preview
|
||||
go-omni new --module example.com/billing ./billing
|
||||
```
|
||||
|
||||
新生成器与运行时一起升级。已有 v0.13 项目先运行 `go-omni api upgrade --dry-run`，再按 [定点迁移步骤](DEVELOPMENT.md#v013-项目升级) 处理；不会静默覆盖自定义 svc/config。运行期的新构造器由生成器维护，项目初始化迁入 `svc.Init`，使用 `OnClose` 登记资源。
|
||||
|
||||
## 本版能力
|
||||
|
||||
- `.api` 支持根数组、可空对象、成功 null；真正 204 独立保留。生成 Logic、Handler、OpenAPI 和漂移检查使用相同语义。
|
||||
- 请求契约控制未知 query、原始 UTF-8、charset、必须/可选/禁止 body 和严格空对象。路由覆盖 App 策略，普通 JSON 只解析一次。
|
||||
- multipart 声明文件、文本和 JSON 表单字段。Logic 收到校验后的 DTO；文件有界暂存、流式读取、请求结束清理，保留底层 raw/multipart/下载扩展。
|
||||
- 完整项目配置支持环境覆盖、显式零值、空值策略、必填、嵌套及复杂类型。独立校验先于日志和连接创建。
|
||||
- `lifecycle.Runtime` 统一逆序清理、幂等关闭、失败回滚及故障保留；App Logger 独立，支持标准 `log.Logger` 与可信请求元数据。提供依赖中间件装配示例和可选 context 错误映射。
|
||||
- 官方 `database/mysql` 适配器提供结构化配置、每连接池独立 TLS/mTLS、驱动日志、启动检查与失败清理。继续返回同一 `database.DB`，不自动迁移表或重试业务事务。
|
||||
- 字段注释、示例和枚举说明进入 DTO/OpenAPI；`api format` 幂等格式化。Go 错误目录可显式导出供文档使用，无需复制错误定义。
|
||||
- 显式共享契约 roots、来源摘要、分文件 DTO、多服务 workspace 命令、基础模板升级预览；保留目录边界及业务文件所有权。
|
||||
|
||||
详见 [业务开发指南](DEVELOPMENT.md)、[数据库接入](database/mysql/README.md) 和 [验收记录](reports/businessDevelopmentAcceptance.md)。
|
||||
|
||||
全量 race（含生成项目）、vet、build 与本地进程验收通过。发布后的空缓存远程消费者和隔离 MySQL 验收也均通过；CLI/框架同版且无本地 replace。标签固定在 `f5478cdc7662704b164637649305361e52f7c598`，报告单独提交。
|
||||
|
||||
仍需业务维护：契约、配置、svc 依赖创建/探针/清理登记、错误目录、Logic、Repository 和权限中间件。特殊协议可使用保留的扩展点。声明式上传的暂存磁盘和并发量需配置容量；共享契约版本标签由项目管理，框架校验摘要但不下载依赖。此版仍为 preview，不代表 eTax/ePay 已完成业务迁移。
|

|

# v0.13.0-preview（历史版本）
|
||||
|
||||
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。
|
||||
|
||||
## 使用与升级
|
||||
|
||||
```sh
|
||||
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
|
||||
```
|
||||
|
||||
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。
|
||||
|
||||
## 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_SCAFFOLD_INTEGRATION=1 go test -race -p=1 -count=1 -timeout=300s ./...
|
||||
go vet ./...
|
||||
go build ./...
|
||||
python3 scripts/verifyErrorCatalogRelease.py --version v0.10.0-preview
|
||||
python3 scripts/verifyCompatibilityRelease.py --version v0.10.0-preview \
|
||||
--report performance/errorCatalogCompatibilityRemote.json
|
||||
python3 scripts/verifyManagedProject.py --report performance/lifecycleEndpointsLocal.json
|
||||
python3 scripts/verifyManagedRelease.py --version v0.13.0-preview --report performance/lifecycleEndpointsRemote.json
|
||||
```
|
||||
|
||||
测试覆盖多 App 隔离、并发原因隔离、精确 int64、重复/非法定义拒绝、200 失败与 403 覆盖、未知错误兜底、已提交响应不追加、文本回执、访问日志、指标/链路、标准桥接、本地与序列化共享幂等存储，以及真实生成项目的 early middleware、raw 输出和重生成保护。远程脚本从全新缓存安装 CLI，检查固定版本、模块校验和与没有本地 replace。
|
||||
发布后的远程空缓存验收已通过，耗时 26.55 秒；[机器报告](performance/lifecycleEndpointsRemote.json) 确认 CLI 和生成项目使用同版远程 module，无本地 replace。报告单独提交，发布标签保持在代码提交 `f0991d3ff248e4cb32812c368f0f8ba28740a6c7`。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。
|
||||
|
||||
本版结果见 [统一错误目录验收](performance/errorCatalogAcceptance.md)。
|
||||
---
|
||||
|
||||
历史 Connector/HTTP 配置验收保留在 [v0.9.1 记录](performance/connectorAcceptance.md)，历史版本变化见 [CHANGELOG](CHANGELOG.md)。
|
||||
# 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-omni CLI
|
||||
|
||||
首次接入见 [README](../../README.md)，无需克隆框架源码。本页说明命令参数；下方 `go run ./cmd/go-omni` 示例在框架仓库中执行，并显式引用本地源码。
|
||||
v0.18 新增：可空嵌套映射、`mappingFiles` 配置拆分、显式 nil 策略和可选 `pointerResult`。原 v0.17 配置继续有效，见 [生成能力指南](../../GENERATION.md)。
|
||||
|
||||
## API 契约驱动项目
|
||||
v0.17 增加公共字段组合、可选结构映射、自动中间件工厂和按需 Repository。配置和迁移见 [生成能力指南](../../GENERATION.md)。
|
||||
|
||||
v0.16 增加基础类型/动态 JSON 数组返回、OpenAPI 公共引用和 workspace Go Catalog 统一导出。见 [接入与筛选规则](../../DEVELOPMENT.md#同一份-go-错误目录供多个服务生成)。
|
||||
|
||||
v0.14 新增 `api format [--check]`、`api upgrade [--dry-run|--preview <空目录>|--apply]`，以及 `workspace format|generate|check --file omni.workspace.json`。详见 [通用开发指南](../../DEVELOPMENT.md)。
|
||||
|
||||
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@v0.18.0-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 返回 501；中间件工厂未实现时阻止启动，既有 handler 模式仍返回 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。
|
||||
|
||||
`v0.10.0-preview` 新增 `errorCatalog`：集中配置业务码、提示和 HTTP 状态，支持默认 HTTP 200 与单条覆盖，生成函数、路由策略和 OpenAPI 共用一份定义。语法及配置方式见 [统一错误目录](../../errors/README.md)。
|
||||
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。
|
||||
|
||||
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。
|
||||
|
||||
## 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 v0.18.0-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)。
|
||||
当前模板与依赖以 v0.18.0-preview 为基线，继续使用 manifest v2；GORM 可选适配器从 v0.14.1-preview 提供。已有项目使用 [定点升级与预览](../../DEVELOPMENT.md#v013-项目升级)：原始模板可自动替换，含业务修改的基础文件按预览合并；通用清理由 Runtime 负责。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
|
||||
GOPRIVATE=git.yuntuo.hk go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.10.0-preview
|
||||
go-omni new --framework-version v0.10.0-preview --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 it with @server(response: Name) or @response Name to share a public body;
|
||||
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 API contract, independently of the app's default response configuration.
|
||||
Handlers reject nil successful responses. Body DTOs use application/json and have a 1 MiB limit by default.
|

Use contract.Binder.Bind's optional limit in a custom adapter for larger payloads.

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.
|
||||
Object responses reject nil; []DTO maps nil to []; *DTO permits null; returns(null) is a successful null value. No returns means 204. Body DTOs use application/json and have a 1 MiB limit by default.
|

Use @body(maxBytes: ...) for route limits. @body(mode: raw|multipart; maxBytes: ...)

adds a *httpx.Body argument to Logic, without handwritten handlers. Raw is the exact

limited request stream; Parts supports sequential multipart reading with no temp files.
|
||||
@produces "application/octet-stream" (or another concrete media type) generates a

Logic result of *httpx.Stream; the handler closes Content and streams it unwrapped.
|

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

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

Alternatively, declare public business errors in error (...) and reference them with @errors.

Use internal/apierrors constructors to share status, code and message with OpenAPI.

Auth declarations connect a bearer/header/cookie scheme to a real named middleware.
|

The selected auth runs first; @auth none removes inherited declarative auth.

Validation policy remains in the middleware implementation. Public messages must

not contain secrets; error causes may be included in server logs.

Generated svc.New receives Config and a borrowed Logger. Add dependencies in svc.Init,
|

then immediately register each cleanup with OnClose. A later initialization failure
|

runs registered cleanups in reverse order. Close is idempotent. GlobalMiddleware

provides global hooks; Middlewares supplies named API hooks. AppOptions is evaluated

once before route registration; logging is configured earlier through Config.

The generated main runs HTTP draining, all OnStop hooks, all OnDrain hooks, resource

OnClose callbacks, then logger close. Stop/drain hooks within a phase run concurrently;
|

combine components with ordering dependencies into one pair. Pair OnStop/OnDrain
|

with the same name. OnDrain returns nil only after final work and acknowledgements
|

have finished. Use WorkContext for accepted background work; Context is an early
|
||||
shutdown notification. server.lifecycle configures stopTimeout (5s), drainTimeout
|
||||
(10s), and cancelTimeout (5s grace per timed-out phase). Zero uses defaults.
|
||||
Timeout/failure cancels WorkContext. If hooks cannot prove completion, resources
|
||||
and the borrowed logger are retained and the generated process exits unsuccessfully.
|
||||
Errors retain their causes. No automatic retry of close or force killing of goroutines.
|
||||
Do not close borrowed resources or attach duplicate cleanup hooks to App. The startup
|
||||
context cancels on signals; long-lived clients/workers that requests depend on need
|
||||
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
