接口调用请求说明

http请求方式：POST（请使用https协议） https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN

{
     "button":[
     {
          "type":"click",
          "name":"今日歌曲",
          "key":"V1001_TODAY_MUSIC"
      },
      {
           "name":"菜单",
           "sub_button":[
           {
               "type":"view",
               "name":"搜索",
               "url":"http://www.soso.com/"
            },
            {
               "type":"view",
               "name":"视频",
               "url":"http://v.qq.com/"
            },
            {
               "type":"click",
               "name":"赞一下我们",
               "key":"V1001_GOOD"
            }]
       }]
 }

从说明文档上我们可以看出，只要我们把菜单改写成这种json格式，然后以Post的方式提交到指定的地址就可以。

　　

            FileStream fs1 = new FileStream(Server.MapPath(".") + "\\Btnconfig.txt", FileMode.Open);
            StreamReader sr = new StreamReader(fs1, Encoding.GetEncoding("UTF-8"));
            string menu = sr.ReadToEnd();
            sr.Close();
            fs1.Close();

　　首先，获取到文本文件中写的菜单配置文件的内容。

 string url = GetPage("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=****&secret=****", "POST", "");
            TokenModel token = Newtonsoft.Json.JsonConvert.DeserializeObject<TokenModel>(url);
            if (token.access_token != null)
                Response.Write(token.access_token);
            else
            {
                ResultModel rm = Newtonsoft.Json.JsonConvert.DeserializeObject<ResultModel>(url);
                Response.Write(rm.errcode);
            }

　　获取到你公众号的Token

 string message = GetPage("https://api.weixin.qq.com/cgi-bin/menu/create?access_token=" + token.access_token + "", "POST", menu);
            Response.Write(message);

　　Post到指定的地址。看下返回码，是不是0，是的话，就成功了，如果不是，看下下面这个地址，看看是哪里出错了

                sr = new StreamReader(instream, encoding);
                //返回结果网页（html）代码
                string content = sr.ReadToEnd();
                string err = string.Empty;
                return content;
            }
            catch (Exception ex)
            {
                string err = ex.Message;
                return string.Empty;
            }
        }
