Automatic parameter binding tool base on go-gin

中文文档

• 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

directory structure description

• ginrpc/base/common.go Base Library
• ginrpc/base/api/context.go customize context content
• Supporting Automatic Detection of Parameters binding:"required" validator
• Support RPC automatic mapping

Support three of interface modes

• func(*gin.Context) //gin Primitive interface func(*api.Context) //Custom context type
• func(*api.Context,req) //Custom context type,Request parameters with req func(*api.Context,req)
• func(*gin.Context,*req)//go-gin context ,Request parameters with req func(*gin.Context,req)

Sample code

init(sample mod is ginweb )

``` go mod init ginweb ```

coding (detailed address：https://github.com/xxjwxc/ginrpc/tree/master/sample/ginweb)

package main

import (
	"fmt"
	"net/http"

	_ "ginweb/routers" // 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"` // 带校验方式
	Password     string `json:"password"`
}

// Hello ...
type Hello struct {
	Index int
}

// Hello 带注解路由(参考beego形式)
// @router /block [post,get]
func (s *Hello) Hello(c *api.Context, req *ReqTest) {
	fmt.Println(req)
	fmt.Println(s.Index)
	c.JSON(http.StatusOK, "ok")
}

// Hello2 不带注解路由(参数为2默认post)
func (s *Hello) Hello2(c *gin.Context, req ReqTest) {
	fmt.Println(req)
	fmt.Println(s.Index)
	c.JSON(http.StatusOK, "ok")
}

//TestFun1 gin 默认的函数回调地址
func TestFun1(c *gin.Context) {
	fmt.Println(c.Params)
	c.String(200, "ok")
}

//TestFun2 自定义context的函数回调地址
func TestFun2(c *api.Context) {
	fmt.Println(c.Params)
	c.JSON(http.StatusOK, "ok")
}

//TestFun3 带自定义context跟已解析的req参数回调方式
func TestFun3(c *api.Context, req *ReqTest) {
	fmt.Println(c.Params)
	fmt.Println(req)
	c.JSON(http.StatusOK, "ok")
}

//TestFun4 带自定义context跟已解析的req参数回调方式
func TestFun4(c *gin.Context, req ReqTest) {
	fmt.Println(c.Params)
	fmt.Println(req)

	c.JSON(http.StatusOK, req)
}

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()
	h := new(Hello)
	h.Index = 123
	base.Register(router, h)                          // 对象注册
	router.POST("/test1", base.HandlerFunc(TestFun1)) // 函数注册
	router.POST("/test2", base.HandlerFunc(TestFun2))
	router.POST("/test3", base.HandlerFunc(TestFun3))
	router.POST("/test4", base.HandlerFunc(TestFun4))
	base.RegisterHandlerFunc(router, []string{"post", "get"}, "/test", TestFun1) // 多种请求方式注册

	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"}'
  

Annotation routing

• 1.Annotation route will automatically create[mod]/routers/gen_router.go file and 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 the secondary file, and you can embed it without adding the above code)

• 2.Annotation route call mode:

   base := ginrpc.New(ginrpc.WithCtx(func(c *gin.Context) interface{} {
   	return api.NewCtx(c)
   }), ginrpc.WithDebug(true), ginrpc.WithGroup("xxjwxc"))
   base.Register(router, new(Hello))                          // 对象注册
   router.Run(":8080")

• 3.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"}'
  

• 4 Parameter description ginrpc.WithCtx ： Set custom context ginrpc.WithDebug(true) : set debug style ginrpc.WithGroup("xxjwxc") : Add routing prefix (you can also use gin. Group grouping) ginrpc.WithBigCamel(true) : Set big hump standard (false is web mode, _, lowercase)
