这是微信公众平台上的说明地址。
另外订阅号是没有这个权限的，认证过的公众号才可以有这个权限。
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

public string GetPage(string posturl, string Method, string postData)
{
Stream outstream = null;
Stream instream = null;
StreamReader sr = null;
HttpWebResponse response = null;
HttpWebRequest request = null;
Encoding encoding = Encoding.UTF8;
byte[] data = encoding.GetBytes(postData);
// 准备请求...
try
{
// 设置参数
request = WebRequest.Create(posturl) as HttpWebRequest;
CookieContainer cookieContainer = new CookieContainer();
request.CookieContainer = cookieContainer;
request.AllowAutoRedirect = true;
request.Method = Method;
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
outstream = request.GetRequestStream();
outstream.Write(data, 0, data.Length);
outstream.Close();
//发送请求并获取相应回应数据
response = request.GetResponse() as HttpWebResponse;
//直到request.GetResponse()程序才开始向目标网页发送Post请求
instream = response.GetResponseStream();
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;
}
}
