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服务开发高级特性自定义状态码处理.md

我们可以对WebServer指定的状态码进行自定义处理,例如针对常见的 404/403/500 等错误,我们可以展示自定义的错误信息、页面内容,或者跳转到一个特定的页面。

相关方法如下:

func (s *Server) BindStatusHandler(status int, handler HandlerFunc)
func (s *Server) BindStatusHandlerByMap(handlerMap map[int]HandlerFunc)

func (d *Domain) BindStatusHandler(status int, handler HandlerFunc)
func (d *Domain) BindStatusHandlerByMap(handlerMap map[int]HandlerFunc)

可以看到,我们可以使用 BindStatusHandler 或者 BindStatusHandlerMap 来实现针对指定的状态码进行自定义的回调函数处理,并且该特性也支持针对特定的域名绑定。我们来看几个简单的示例。

基本使用

package main

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

func main() {
    s := g.Server()
    s.BindHandler("/", func(r *ghttp.Request){
        r.Response.Writeln("halo 世界!")
    })
    s.BindStatusHandler(404, func(r *ghttp.Request){
        r.Response.Writeln("This is customized 404 page")
    })
    s.SetPort(8199)
    s.Run()
}

执行后,我们访问没有绑定的路由页面,例如 http://127.0.0.1:8199/test ,可以看到,页面显示了我们期望的返回结果: This is customized 404 page。

此外,常见的Web页面请求错误状态码处理方式,是引导用户跳转到指定的错误页面,因此,在状态码回调处理函数中,我们可以使用 r.RedirectTo 方法来进行页面跳转,示例如下:

package main

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

func main() {
    s := g.Server()
    s.BindHandler("/status/:status", func(r *ghttp.Request) {
        r.Response.Write("woops, status ", r.Get("status"), " found")
    })
    s.BindStatusHandler(404, func(r *ghttp.Request){
        r.Response.RedirectTo("/status/404")
    })
    s.SetPort(8199)
    s.Run()
}

执行后,我们手动通过浏览器访问一个不存在的页面,例如 http://127.0.0.1:8199/test ,可以看到,页面被引导跳转到了 http://127.0.0.1:8199/status/404 页面,并且可以看到页面返回内容: woops, status 404 found

批量设置

package main

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

func main() {
    s := g.Server()
    s.BindStatusHandlerByMap(map[int]ghttp.HandlerFunc {
        403 : func(r *ghttp.Request){r.Response.Writeln("403")},
        404 : func(r *ghttp.Request){r.Response.Writeln("404")},
        500 : func(r *ghttp.Request){r.Response.Writeln("500")},
    })
    s.SetPort(8199)
    s.Run()
}

可以看到,我们可以通过 BindStatusHandlerByMap 方法对需要自定义的状态码进行批量设置。该示例程序执行后,当服务接口返回的状态码为 403/404/500 时,接口将会返回对应的状态码数字。

注意事项

在自定义状态码处理方法中如果涉及到内容的输出,往往需要使用 r.Response.ClearBuffer() 方法将原本缓冲区的输出内容清空。

    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

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.
