golang接收post和get请求参数处理

"http://localhost:8080/api/book/paging/"+this.pageNum+"/"+this.pageSize
//形式为："http://localhost:8080/api/book/paging/2/2

r.GET("/api/book/paging/:page_num/:page_size",controller.Paging)

pageSize,_:=strconv.Atoi(ctx.Param("page_size"))//它是下面的简写
pageNum,_:=strconv.Atoi(ctx.Params.ByName("page_num"))

"http://localhost:8080/api/book/paging?page_num="+this.pageNum+"&page_size="+this.pageSize
//形式为："http://localhost:8080/api/book/paging?page_num=2&page_size=2

r.GET("/api/book/paging",controller.Paging)

pageSize,_:=strconv.Atoi(ctx.Query("page_size"))
pageNum,_:=strconv.Atoi(ctx.Query("page_num"))

    var requestUser=model.User{}
    _=ctx.Bind(&requestUser)
    //获取参数
    telephone:=requestUser.Telephone
    password:=requestUser.Password

    //使用map获取请求的参数
    var requestMap=make(map[string]string)
    _ = json.NewDecoder(ctx.Request.Body).Decode(&requestMap)

    var requestRegister=model.User{}
    json.NewDecoder(ctx.Request.Body).Decode(&requestRegister)
