# 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。

# 通用业务开发能力完善计划
本轮目标:业务维护契约、配置、依赖装配与业务逻辑,框架持续维护 HTTP 接入、契约校验、通用运行期与文档。按实际生成项目和可删除的业务适配点验收,不写入 eTax 业务规则。
## 实施与验收清单
- [x] 运行期:资源登记、逆序释放、幂等关闭、失败回滚、故障原因保留归框架;生成入口与项目依赖初始化边界明确。多 App 日志隔离、标准 log.Logger 适配、可信请求元数据与依赖中间件示例。
- [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。

# 通用业务开发指南(v0.14.0-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。
## 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)` | 数组;nil 统一输出 `[]` |
| `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。根类型当前支持以上四种形式,嵌套字段继续支持既有 slice/map/pointer/scalar/any。
## 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。
## 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)
c.Middlewares["RequireAccess"] = middleware.NewRequireAccess(client)
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。项目清理函数仍须自行停止、等待后台任务并保证能返回,框架不能强制杀死任意 goroutine。
中间件用业务所需的小接口接收依赖,避免反向导入 svc:
```go
// internal/middleware/accessFactory.go
package middleware
import (
"context"
"git.yuntuo.hk/k2safe/go-omni/httpx"
)
type AccessChecker interface {
CheckAccess(context.Context, string) error
}
func NewRequireAccess(checker AccessChecker) httpx.Middleware {
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)
}
}
}
```
`.api` 声明对应 middleware 后,保留生成的初始 hook,并另建上述工厂;在 Init 用工厂替换 registry 的同名项即可。该包只依赖接口和 HTTP 抽象,不导入 svc,也不把数据库藏到 context 里。
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,显式导出文档元数据:
```go
// 在项目自己的导出命令中;appErrors.Catalog 与 AppOptions 注册同一函数。
if err := omnierrors.ExportCatalog(os.Stdout, appErrors.Catalog()); err != nil {
log.Fatal(err)
}
```
```sh
go run ./cmd/exportErrors > api/omni.errors.json
go-omni api generate
```
文件是派生产物,应纳入版本控制并由业务 CI 检查导出漂移。CLI 自动读取入口目录的 `omni.errors.json`,校验错误目录、合并状态/模板参数/具体示例到 OpenAPI;不会运行项目 Go,不创建另一份运行期注册器。带独立错误目录的路由继续使用自己的目录。没有路由级精确错误列表时,文档描述 App 目录的公共错误集合;特殊自定义 Encoder 的文档由项目显式扩展。
## 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。
## 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 v0.14.0-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。

# 生成项目与文件维护边界
v0.14.1-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/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,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:`internal/svc/runtimeGen.go`、`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。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。静态 OpenAPI 不执行 Go;可从同一 Catalog 显式导出 `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,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。
<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 v0.14.1-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。

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。
新增通用开发能力见 [业务开发指南](DEVELOPMENT.md):数组/null、严格请求策略、声明式上传、完整配置环境覆盖、资源生命周期、共享契约和升级工具。MySQL 直接使用 [官方适配器](database/mysql/README.md)。
使用 GORM 的项目可以选择 [gormx 适配器](database/gormx/README.md),复用数据库初始化和连接池,并将 SQL 日志接入 logx。

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

```
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:

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。
---
# 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)

# 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。
v0.14 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)。
## 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@v0.14.1-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。
`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。
`v0.11.0-preview` 增加有序模板参数,生成带类型的错误函数和具体文档示例;示例见 [errorParams.api](../../examples/contracts/errorParams.api)。新生成代码需要同版或更新框架。
`v0.11.1-preview` 修复未声明错误的生成路由遮蔽 App 错误目录:错误可只在 Go 中注册一次,`.api` 不必重复维护;返回格式和路由参数继续按契约生成。
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 v0.14.1-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)。
模板最低需要 v0.14.0-preview 的通用 Runtime、配置和绑定能力,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@v0.11.1-preview
go-omni new --framework-version v0.11.1-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 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
bounded buffering. Stream reads respect configured server timeouts. Declare multipart/multipartJSON/file DTO fields for validated uploads; without those fields the existing streaming Body is passed. form tags remain URL query parameters. The optional manual
handler/custom binder hooks are preserved, and are needed only for custom protocols.
Fields require exactly one source tag: json, path, form (URL query only), header.

Declare public business errors in error (...) and reference them with @errors.
Go-owned errors can be registered once through svc.ServiceContext.AppOptions with

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 before closing svc resources, then the logger.
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

makes readiness 503; it does not turn a running process's liveness into failure.
