Asp.Net利用HttpWebRequest发送复杂的HTTP GET请求并且取回响应

 1 string uri = "https://api.weixin.qq.com/cgi-bin/menu/get?access_token="+AccessToken.IsExistAccess_Token();
 2 var hwrequest = WebRequest.Create(uri) as HttpWebRequest;
 3 hwrequest.Method = "GET";
 4 hwrequest.Timeout = 5000;
 5 
 6 //返回来自 Internet 资源的响应。
 7 HttpWebResponse res = hwrequest.GetResponse() as HttpWebResponse;
 8 //读取流
 9 Stream outs = res.GetResponseStream();
10 StreamReader sr = new StreamReader(outs,Encoding.UTF8);
