GoFrame v2 development skill. Use only when the target Go project uses or is explicitly adopting GoFrame v2: the nearest go.mod requires github.com/gogf/gf/v2, existing Go files import github.com/gogf/gf/v2 or any github.com/gogf/gf/v2/... component package, or the user asks to scaffold, migrate, or build with GoFrame. Trigger for GoFrame-backed Go work such as APIs/controllers/services, middleware, routing/config, ORM/DAO/DO/entity/database operations, gf CLI/codegen, HTTP/gRPC services, and microservice conventions. Do not trigger for generic Go projects without GoFrame evidence, frontend-only work, shell scripts, or unrelated infrastructure tasks.

referencesWEB服务开发请求输入请求输入-Context.md

基本介绍

请求流程往往会在上下文中共享一些自定义设置的变量,例如在请求开始之前通过中间件设置一些变量,随后在路由服务方法中可以获取该变量并相应对一些处理。这种需求非常常见。在 GoFrame 框架中,我们推荐使用 Context 上下文对象来处理流程共享的上下文变量,甚至将该对象进一步传递到依赖的各个模块方法中。该 Context 对象类型实现了标准库的 context.Context 接口,该接口往往会作为模块间调用方法的第一个参数,该接口参数也是 Golang 官方推荐的在模块间传递上下文变量的推荐方式。

方法列表:

func (r *Request) GetCtx() context.Context
func (r *Request) SetCtx(ctx context.Context)
func (r *Request) GetCtxVar(key interface{}, def ...interface{}) *gvar.Var
func (r *Request) SetCtxVar(key interface{}, value interface{})

简要说明:

  1. GetCtx 方法用于获取当前的 context.Context 对象,作用同 Context 方法。
  2. SetCtx 方法用于设置自定义的 context.Context 上下文对象。
  3. GetCtxVar 方法用于获取上下文变量,并可给定当该变量不存在时的默认值。
  4. SetCtxVar 方法用于设置上下文变量。

使用示例

示例1, SetCtxVar/GetCtxVar

package main

import (
    "github.com/gogf/gf/v2/frame/g"
    "github.com/gogf/gf/v2/net/ghttp"
)

const (
    TraceIdName = "trace-id"
)

func main() {
    s := g.Server()
    s.Group("/", func(group *ghttp.RouterGroup) {
        group.Middleware(func(r *ghttp.Request) {
            r.SetCtxVar(TraceIdName, "HBm876TFCde435Tgf")
            r.Middleware.Next()
        })
        group.ALL("/", func(r *ghttp.Request) {
            r.Response.Write(r.GetCtxVar(TraceIdName))
        })
    })
    s.SetPort(8199)
    s.Run()
}

可以看到,我们可以通过 SetCtxVar 和 GetCtxVar 来设置和获取自定义的变量,该变量生命周期仅限于当前请求流程。

示例2, SetCtx

SetCtx 方法常用于中间件中整合一些第三方的组件,例如第三方的链路跟踪组件等等。

为简化示例,这里我们将上面的例子通过 SetCtx 方法来改造一下来做演示。

package main

import (
    "context"
    "github.com/gogf/gf/v2/frame/g"
    "github.com/gogf/gf/v2/net/ghttp"
)

const (
    TraceIdName = "trace-id"
)

func main() {
    s := g.Server()
    s.Group("/", func(group *ghttp.RouterGroup) {
        group.Middleware(func(r *ghttp.Request) {
            ctx := context.WithValue(r.Context(), TraceIdName, "HBm876TFCde435Tgf")
            r.SetCtx(ctx)
            r.Middleware.Next()
        })
        group.ALL("/", func(r *ghttp.Request) {
            r.Response.Write(r.Context().Value(TraceIdName))
            // 也可以使用
            // r.Response.Write(r.GetCtxVar(TraceIdName))
        })
    })
    s.SetPort(8199)
    s.Run()
}

执行后,访问 http://127.0.0.1:8199/ ,页面输出内容为:

    The skill provides a comprehensive development guide and code examples for the GoFrame v2 framework. While highly informative for Go developers, it contains several examples with hardcoded placeholder secrets, tokens, and specific local file paths to sensitive configuration files (like Kubernetes credentials). These elements are provided for demonstration purposes but represent insecure practices if used in production without modification.

README badge for gogf/skills

Provides instruction and conventions for developing with GoFrame v2, a modular Go framework for building HTTP and gRPC services, microservices, and database operations using its ORM, CLI tooling, and project scaffolding. Use this skill when the target project has GoFrame v2 as a dependency or when the user requests scaffolding, migrations, or service development with GoFrame conventions.

Generated from the current SKILL.md.

When should I use this skill?
Use this skill only when your Go project uses GoFrame v2, indicated by github.com/gogf/gf/v2 in go.mod or imports. Do not use for generic Go projects, frontend work, or infrastructure tasks unrelated to GoFrame.
Should I manually set created_at and updated_at fields?
No. GoFrame automatically writes created_at on insert and updated_at on insert/update/save. Manually setting these fields is redundant and violates project conventions.
What should I use for database operations instead of g.Map?
Always use DO objects from internal/model/do/. DO struct fields are interface{}, unset fields remain nil and are automatically ignored by the ORM.
How does soft delete work in GoFrame?
Call Delete() on the DAO; GoFrame automatically converts it to UPDATE SET deleted_at = NOW(). Queries automatically filter out soft-deleted rows without requiring manual WhereNull conditions.
Where should I implement business logic?
Implement business logic directly in the service/ directory. Do not use the logic/ directory unless explicitly requested.
