C#微信公众平台菜单开发的详细介绍

  根据开发者appid(应用id)和appsecret（应用密钥）获取access_token值，请求地址是：https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=wx69e10a281a17e81f&secret=cff1fa9d984a3d122cadfbb901ecfa32，其中“wx69e10a281a17e81f”是微信圈圈的appid，“cff1fa9d984a3d122cadfbb901ecfa32”是微信圈圈的appsecret，获取access_token后，菜单请求地址是：https://api.weixin.qq.com/cgi-bin/menu/create?access_token=值，将获取到的access_token值代入链接地址中，即可创建一组菜单。

菜单创建格式：

{    "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"                }            ]        }    ]}

若不是第一次创建菜单，则需在创建菜单前，删除已存在的菜单，删除菜单请求地址是：https://api.weixin.qq.com/cgi-bin/menu/delete?access_token=值，将获取到的ACCESS_TOKEN值代入链接地址中，即可删除已存在的菜单。

示例：

菜单创建片段：

string postString = "{"button":[{"name":"讯息速递","sub_button":[{"type":"click","name":"改版公告","key":"RevisionNotice"},{"type":"view","name":"春天读好书","url":"http://ah.10086.cn/new/s/ydty/ctdhsxscd "}]},{"name":"我要分享","sub_button":[{"type":"click","name":"读 · 好书","key":"bookRanking"},{"type":"click","name":"听 · 酷音","key":"musicRanking"},{"type":"click","name":"玩 · 趣游","key":"gameRanking"}]},{"name":"个人中心","sub_button":[{"type":"click","name":"身份验证","key":"BDClick"},{"type":"click","name":"积分兑换","key":"OnExchange"},{"type":"click","name":"积分规则说明","key":"IntegralRule"}]}]}";  //微信圈圈菜单

byte[] postData = Encoding.UTF8.GetBytes(postString);//编码，尤其是汉字，事先要看下抓取网页的编码方式  

string url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=LZTCC_eaEHVsEh9pEczSYqGzrphoCsSiTtkbMwDj5yqkQVlP3rObDxxIm6J7cG39mLljSw9H18efkwEK0dHrCTlbKBXOJf2BHFuNZ4MZRBM";//根据获取的ACCESS_TOKEN值代入链接中创建菜单

WebClient webClient = new WebClient();

webClient.Headers.Add("Content-Type", "application/x-www-form-urlencoded");//采取POST方式必须加的header，如果改为GET方式的话就去掉这句话即可  

byte[] responseData = webClient.UploadData(url, "POST", postData);//得到返回字符流  

string srcString = Encoding.UTF8.GetString(responseData);//解码 

Response.Write(srcString);
