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-请求校验.md

Request 对象支持非常完美的请求校验能力,通过给结构体属性绑定 v 标签即可。由于底层校验功能通过 gvalid 模块实现, 更详细的校验规则和介绍请参考 数据校验-Struct校验 章节。 :::warning 以下示例代码中的请求参数转结构体方式适用于框架 v1 版本, v2 版本开始建议通过规范路由实现自动化的参数结构体转换和校验: 路由注册-规范路由 :::

示例1,基本使用

我们将之前的示例做下调整,增加 v 校验标签。

package main

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

// RegisterReq 注册请求数据结构
type RegisterReq struct {
    Name  string `p:"username"  v:"required|length:4,30#请输入账号|账号长度为:{min}到:{max}位"`
    Pass  string `p:"password1" v:"required|length:6,30#请输入密码|密码长度不够"`
    Pass2 string `p:"password2" v:"required|length:6,30|same:password1#请确认密码|密码长度不够|两次密码不一致"`
}

// RegisterRes 注册返回数据结构
type RegisterRes struct {
    Code  int         `json:"code"`
    Error string      `json:"error"`
    Data  interface{} `json:"data"`
}

func main() {
    s := g.Server()
    s.Group("/", func(group *ghttp.RouterGroup) {
        group.ALL("/register", func(r *ghttp.Request) {
            var req *RegisterReq
            if err := r.Parse(&req); err != nil {
                r.Response.WriteJsonExit(RegisterRes{
                    Code:  1,
                    Error: err.Error(),
                })
            }
            // ...
            r.Response.WriteJsonExit(RegisterRes{
                Data: req,
            })
        })
    })
    s.SetPort(8199)
    s.Run()
}

在该示例中,我们定义了两个结构体: RegisterReq 用于参数接收, RegisterRes 用于数据返回。由于该接口返回的是 JSON 数据结构,可以看到,只有返回的结构体中存在 json 标签,而接收的结构体中只有 p 标签。因为 RegisterReq 仅用于参数接收,无需设置返回的 json 标签。 :::tip p 标签是可选的,默认情况下会通过 忽略特殊字符+不区分大小写 的规则进行属性名称匹配转换,默认匹配规则满足绝大部分业务场景。 ::: 为了演示测试效果,这里在正常的返回结果 Data 属性中将 RegisterReq 对象返回,由于该对象没有绑定 json 标签,因此返回的 JSON 字段将会为其属性名称。

执行后,我们通过 curl 工具来测试一下:

$ curl "http://127.0.0.1:8199/register?name=john&password1=123456&password2=123456"
{"code":0,"error":"","data":{"Name":"john","Pass":"123456","Pass2":"123456"}}

$ curl "http://127.0.0.1:8199/register?name=john&password1=123456&password2=12345"
{"code":1,"error":"密码长度不够","data":null}

$ curl "http://127.0.0.1:8199/register"
{"code":1,"error":"请输入账号","data":null}

示例2,校验错误处理

:::tip 最新版已经改成只返回第一个错误。 ::: 可以看到在以上示例中,当请求校验错误时,所有校验失败的错误都返回了,这样对于用户体验不是特别友好。当产生错误时,我们可以将校验错误转换为 gvalid.Error 接口对象,随后可以通过灵活的方法控制错误的返回。

package main

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

type RegisterReq struct {
    Name  string `p:"username"  v:"required|length:4,30#请输入账号|账号长度为:{min}到:{max}位"`
    Pass  string `p:"password1" v:"required|length:6,30#请输入密码|密码长度不够"`
    Pass2 string `p:"password2" v:"required|length:6,30|same:password1#请确认密码|密码长度不够|两次密码不一致"`
}

type RegisterRes struct {
    Code  int         `json:"code"`
    Error string      `json:"error"`
    Data  interface{} `json:"data"`
}

func main() {
    s := g.Server()
    s.Group("/", func(group *ghttp.RouterGroup) {
        group.ALL("/register", func(r *ghttp.Request) {
            var req *RegisterReq
            if err := r.Parse(&req); err != nil {
                // Validation error.
                if v, ok := err.(gvalid.Error); ok {
                    r.Response.WriteJsonExit(RegisterRes{
                        Code:  1,
                        Error: v.FirstError().Error(),
                    })
                }
                // Other error.
                r.Response.WriteJsonExit(RegisterRes{
                    Code:  1,
                    Error: err.Error(),
                })
            }
            // ...
            r.Response.WriteJsonExit(RegisterRes{
                Data: req,
            })
        })
    })
    s.SetPort(8199)
    s.Run()
}

可以看到,当错误产生后,我们可以通过 err.(gvalid.Error) 断言的方式判断错误是否为校验错误,如果是的话则返回第一条校验错误,而不是所有都返回。更详细的错误控制方法,请参考 数据校验-校验结果 章节。 :::tip 此外,我们这里也可以使用 gerror.Current 获取第一条报错信息,而不是使用断言判断。例如:

var req *RegisterReq
if err := r.Parse(&req); err != nil {
    r.Response.WriteJsonExit(RegisterRes{
        Code:  1,
        Error: gerror.Current(err).Error(),
    })
}

::: 执行后,我们通过 curl 工具来测试一下:

$ curl "http://127.0.0.1:8199/register"
{"code":1,"error":"请输入账号","data":null}

$ curl "http://127.0.0.1:8199/register?name=john&password1=123456&password2=1234567"
{"code":1,"error":"两次密码不一致","data":null}

    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.
