c# – .NET HTTP POST方法 – Cookie问题

概述我正在尝试使用C#登录hotfile.com.第一个大问题是克服417错误,这条线解决了它： System.Net.ServicePointManager.Expect100Continue = false; 现在,当我尝试使用POST登录时,我收到此错误： You don’t seem to accept cookies. Cookies are required in order to log 我正在尝试使用C#登录hotfile.com.第一个大问题是克服417错误,这条线解决了它：

System.Net.ServicePointManager.Expect100Continue = false;

现在,当我尝试使用POST登录时,我收到此错误：

You don’t seem to accept cookies. cookies are required in order to log in. Help

我已经尝试了几次,并且用Google搜索,我仍然无法登录Hotfile.com ..我的代码是这样的：

string response;byte[] buffer = EnCoding.ASCII.GetBytes("user=XX&pass=XX");cookieContainer cookies = new cookieContainer();httpWebRequest WebReq = (httpWebRequest)WebRequest.Create("http://hotfile.com/login.PHP");WebReq.Credentials = new NetworkCredential("XX","XX");WebReq.PreAuthenticate = true;WebReq.Pipelined = true;WebReq.cookieContainer = cookies;WebReq.KeepAlive = true;WebReq.Method = "POST";WebReq.ContentType = "application/x-www-form-urlencoded";WebReq.ContentLength = buffer.Length;WebReq.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; windows NT 6.0; SLCC1)";Stream PostData = WebReq.GetRequestStream();PostData.Write(buffer,buffer.Length);PostData.Close();httpWebResponse WebResp = (httpWebResponse)WebReq.GetResponse();Stream Answer = WebResp.GetResponseStream();StreamReader _Answer = new StreamReader(Answer);response = _Answer.ReadToEnd();file.WriteallText("dump.HTML",response);

当然,用户和通行证将拥有您的帐户值.

解决方法 这是我为您写的一个工作示例：

var cookies = new cookieContainer();ServicePointManager.Expect100Continue = false;var request = (httpWebRequest)WebRequest.Create("http://www.hotfile.com/login.PHP");request.cookieContainer = cookies;request.Method = "POST";request.ContentType = "application/x-www-form-urlencoded";using (var requestStream = request.GetRequestStream())using (var writer = new StreamWriter(requestStream)){    writer.Write("user=XX&pass=XX&returnto=/");}using (var responseStream = request.GetResponse().GetResponseStream())using (var reader = new StreamReader(responseStream)){    var result = reader.ReadToEnd();    Console.Writeline(result);}
