Gin 注解路由,自动参数绑定工具

中文文档

Automatic parameter binding base on go-gin

Golang gin automatic parameter binding

  • Support for RPC automatic mapping
  • Support object registration
  • Support annotation routing
  • base on go-gin
    on json restful style
  • implementation of parameter filtering and binding with request
  • code registration simple and supports multiple ways of registration

API details

Three interface modes are supported

  • func(*gin.Context) // go-gin Raw interface
    func(*api.Context) // Custom context type
  • func(*api.Context,req) // Custom context type,with request
    func(*api.Context,*req)
  • func(*gin.Context,*req) // go-gin context,with request
    func(*gin.Context,req)

一,Parameter auto binding

package main

import (
    "fmt"
    "net/http"
    "github.com/gin-gonic/gin"
    "github.com/xxjwxc/ginrpc"
    "github.com/xxjwxc/ginrpc/api"
)

type ReqTest struct {
    Access_token string `json:"access_token"`
    UserName     string `json:"user_name" binding:"required"` // With verification mode.带校验方式
    Password     string `json:"password"`
}

//TestFun4 Callback method with custom context and resolved req parameters
func TestFun4(c *gin.Context, req ReqTest) {
    fmt.Println(c.Params)
    fmt.Println(req)

    c.JSON(http.StatusOK, req)
}

func main() {
    base := ginrpc.New() 
    router := gin.Default()
    router.POST("/test4", base.HandlerFunc(TestFun4))
    base.RegisterHandlerFunc(router, []string{"post", "get"}, "/test", TestFun4) // Multiple request mode registration
    router.Run(":8080")
}
  • curl

    curl 'http://127.0.0.1:8080/test4' -H 'Content-Type: application/json' -d '{"access_token":"111", "user_name":"222", "password":"333"}'

二,Object registration (annotation routing)

Initialization project (this project is named after ginweb
)

`` go mod init ginweb ```

package main

import (
    "fmt"
    "net/http"

    _ "ginweb/routers" // Debug mode requires adding [mod] / routes to register annotation routes.debug模式需要添加[mod]/routers 注册注解路由

    "github.com/gin-gonic/gin"
    "github.com/xxjwxc/ginrpc"
    "github.com/xxjwxc/ginrpc/api"
)

type ReqTest struct {
    Access_token string `json:"access_token"`
    UserName     string `json:"user_name" binding:"required"` // With verification mode
    Password     string `json:"password"`
}

// Hello ...
type Hello struct {
}

// Hello Annotated route (bese on beego way)
// @router /block [post,get]
func (s *Hello) Hello(c *api.Context, req *ReqTest) {
    fmt.Println(req)
    c.JSON(http.StatusOK, "ok")
}

// Hello2 Route without annotation (the parameter is 2 default post)
func (s *Hello) Hello2(c *gin.Context, req ReqTest) {
    fmt.Println(req)
    c.JSON(http.StatusOK, "ok")
}


func main() {
    base := ginrpc.New(ginrpc.WithCtx(func(c *gin.Context) interface{} {
        return api.NewCtx(c)
    }), ginrpc.WithDebug(true), ginrpc.WithGroup("xxjwxc"))

    router := gin.Default()
    base.Register(router, new(Hello))                          // object register like(go-micro)
    // or base.Register(router, new(Hello)) 
    router.Run(":8080")
}

– Annotation routing related instructions

// @router /block [post,get]

@router tag  /block router [post,get] method

Note: if there is no annotation route in the object function, the system will add annotation route by default. Post mode: with req (2 parameters (CTX, req)), get mode is a parameter (CTX)

1. Annotation route will automatically create [mod]/routes/gen_router.go
file, which needs to be added when calling:

``
_ "[mod]/routers" // Debug mode requires adding [mod] / routes to register annotation routes

```

By default, the [gen_router. Data] file will also be generated in the root directory of the project (keep this file, and you can embed it without adding the above code)

2. way of annotation route :

more to saying  [ginweb](/sample/ginweb)

3. Parameter description

ginrpc.WithCtx : Set custom context

ginrpc.WithDebug(true) : Set debug mode

ginrpc.WithGroup("xxjwxc") : Add routing prefix (you can also use gin. Group grouping)

ginrpc.WithBigCamel(true) : Set big camel standard (false is web mode, _, lowercase)

4. Execute curl to automatically bind parameters. See the results directly

curl 'http://127.0.0.1:8080/xxjwxc/block' -H 'Content-Type: application/json' -d '{"access_token":"111", "user_name":"222", "password":"333"}'
curl 'http://127.0.0.1:8080/xxjwxc/hello.hello2' -H 'Content-Type: application/json' -d '{"access_token":"111", "user_name":"222", "password":"333"}'
