HttpWebRequest request = GetPostHttpConn(wholeUrl);
byte[] requestData = Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(data));
request.ContentLength = requestData.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(requestData, 0, requestData.Length);
requestStream.Close();
// 接收返回包
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream responseStream = response.GetResponseStream();
StreamReader streamReader = new StreamReader(responseStream, Encoding.GetEncoding("utf-8"));
string responseStr = streamReader.ReadToEnd();
streamReader.Close();
responseStream.Close();
我采用的是服务端方式的通知，因为我要对接的是app， 由app来调用的我的接口。
问题是 我接收到的结果却是一个完整的网页， 是我接收的不对？还是参数填写的不正确？ 有知道的大佬能帮忙解答一下吗？
