这个是返回打印出来的，

下面是我的代码

// 创建自定义菜单
func CreatMenu() {
   token, _ := GetAccesstoken()
   deleurl := "https://api.weixin.qq.com/cgi-bin/menu/delete?access_token=" + token
   response, err := http.Get(deleurl)
   if err == nil {
      fmt.Println("菜单删除正确")
      fmt.Println(response)
   } else {
      fmt.Println("删除菜单错误")
      fmt.Println(response)
   }
   //https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN
   //读取jsonfile
   content, err := ioutil.ReadFile("./common/menu.json")
   if err != nil {
      log.Fatal("Error when opening file: ", err)
   }
   //拼接路由
   createurl := "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=" + token

   payload := strings.NewReader(string(content))

   req, _ := http.NewRequest("POST", createurl, payload)

   req.Header.Add("Content-Type", "application/json")

   response, err = http.DefaultClient.Do(req)
   if err == nil {
      fmt.Println("菜单设置正确")
      fmt.Println(response)
   } else {
      fmt.Printf("设置菜单错误")
   }

}
