求助:模拟POST网站登录的错误!

朋友用易语言模拟了个登录..我截取数据..用C#模拟..发送的POST数据请求头完全一样..可是我写的却无法接收到返回信息

易语言写的却正常..第一张图是正常的数据图..第二张是我C#写的发送的数据图..发回404连接中断

        

private void Verification(string nameString, string pwdString, string proxyString)

        {

                string sURL = "http://q11.3g.qq.com/g/s";

                string postData = "u=" + 号码+ "&p=" + 密码+ "&modifySKey=0&aid=nLoginHandle";

                byte[] data = Encoding.UTF8.GetBytes(postData);

                // 创建一个URL请求 		

                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(sURL);

                request.Method = "POST";

                request.Headers.Add("Accept-Language", "zh-cn");

                request.ContentType = "application/x-www-form-urlencoded";

                request.ContentLength = data.Length;

                request.Accept = "*/*";

                request.UserAgent = "Mozilla/4.0 (compatible; Win32; WinHttp.WinHttpRequest.5)";

                request.ServicePoint.Expect100Continue = false;

                // Send the data.

                Stream dataStream = request.GetResponse();

                dataStream.Write(data, 0, data.Length);

                // 获取响应

                HttpWebResponse response = (HttpWebResponse)request.GetResponse();

                // 获取流包含由服务器返回的内容。

                StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8);

                // 保存返回

                responseFromServer = reader.ReadToEnd();

        }

--------------------编程问答-------------------- // 获取响应
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

这步报错"基础连接已经关闭: 接收时发生错误。" --------------------编程问答--------------------



Stream dataStream = request.GetRequestStream();

dataStream.Write(data, 0, data.Length);

dataStream.Close();

--------------------编程问答--------------------

引用 2 楼 wxkayc 的回复:

C# code
Stream dataStream= request.GetRequestStream();
dataStream.Write(data,0, data.Length);
dataStream.Close();

还是报错..是不是接收返回数据对象没用对... --------------------编程问答-------------------- 补发下图
