Question

我正在尝试使用C＃登录hotfile.com。第一个大问题是克服了417错误，这条线解决了它：

System.Net.ServicePointManager.Expect100Continue = false;

现在我在尝试使用POST登录时收到此错误：

您似乎不接受Cookie。需要Cookie才能登录。帮助

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, 0, 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，用户和通行证会有您的帐户值。

这是我为你写的一个工作案例：

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);
}
