I'm trying to connect to a website that uses cookies. My login is as follows:
private void button1_Click(object sender, EventArgs e)
{
try
{
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(baseurl);
req.Referer = referer;
req.AllowAutoRedirect = true;
req.KeepAlive = true;
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
byte[] postbuf = Encoding.ASCII.GetBytes(login);
req.ContentLength = postbuf.Length;
Stream rs = req.GetRequestStream();
rs.Write(postbuf, 0, postbuf.Length);
rs.Close();
cookie = req.CookieContainer = new CookieContainer();
WebResponse resp = req.GetResponse();
string s = "";
foreach (Cookie c in cookie.GetCookies(req.RequestUri))
{
s += ("Cookie['" + c.Name + "']: " + c.Value);
}
textBox1.Text = s;
resp.Close();
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex);
}
}
The cookie has 2 keys with values. Then I try to send a post request to the website as follows:
private void button2_Click(object sender, EventArgs e)
{
try
{
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(search);
req.Referer = referer;
req.AllowAutoRedirect = true;
req.KeepAlive = true;
req.CookieContainer = cookie;
StreamReader reader = new StreamReader(req.GetResponse().GetResponseStream());
if (reader != null)
{
string data = reader.ReadToEnd();
reader.Close();
textBox1.Text = data;
}
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex);
}
}
But I get an error that it cannot authenticate. When I login using firefox, I see that the cookie contains much more entries.
What is wrong with my code?
