I use this code to login:
CookieCollection cookies = new CookieCollection();
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("example.com");
request.CookieContainer = new CookieContainer();
request.CookieContainer.Add(cookies);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
cookies = response.Cookies;
string getUrl = "example.com";
string postData = String.Format("my parameters");
HttpWebRequest getRequest = (HttpWebRequest)WebRequest.Create(getUrl);
getRequest.CookieContainer = new CookieContainer();
getRequest.CookieContainer.Add(cookies);
getRequest.Method = WebRequestMethods.Http.Post;
getRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.2; WOW64; rv:19.0) Gecko/20100101 Firefox/19.0";
getRequest.AllowWriteStreamBuffering = true;
getRequest.ProtocolVersion = HttpVersion.Version11;
getRequest.AllowAutoRedirect = true;
getRequest.ContentType = "application/x-www-form-urlencoded";
byte[] byteArray = Encoding.ASCII.GetBytes(postData);
getRequest.ContentLength = byteArray.Length;
Stream newStream = getRequest.GetRequestStream();
newStream.Write(byteArray, 0, byteArray.Length);
newStream.Close();
HttpWebResponse getResponse = (HttpWebResponse)getRequest.GetResponse();
using (StreamReader sr = new StreamReader(getResponse.GetResponseStream(), Encoding.GetEncoding("windows-1251")))
{
doc.LoadHtml(sr.ReadToEnd());
webBrowser1.DocumentText = doc.DocumentNode.OuterHtml;
}
then I want to use HtmlWeb (HtmlAgilityPack) or Webclient to parse the HTML to HtmlDocument(HtmlAgilityPack).
My problem is that when I use:
WebClient wc = new WebClient();
webBrowser1.DocumentText = wc.DownloadString(site);
or
doc = web.Load(site);
webBrowser1.DocumentText = doc.DocumentNode.OuterHtml;
The login disappear so i think I must somehow pass the cookies.. Any suggestions?
