Difficulties with google authentication
- by user283405
I am trying to authenticate google with the following code but google sent me back to the login page again.
//STEP# 1
string loginURL = "https://www.google.com/accounts/ServiceLoginBox?service=analytics&nui=1&hl=en-US&continue=https%3A%2F%2Fwww.google.com%2Fanalytics%2Fsettings%2F%3Fet%3Dreset%26hl%3Den%26et%3Dreset%26hl%3Den-US";
request = (HttpWebRequest)WebRequest.Create(loginURL);
request.CookieContainer = cookieJar;
request.Method = "GET";
request.KeepAlive = true;
request.UserAgent = "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.4) Gecko/2008111217 Fedora/3.0.4-1.fc10 Firefox/3.0.4";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
foreach (Cookie cook in response.Cookies)
{
cookieJar.Add(cook);
}
using (StreamReader sr = new StreamReader(response.GetResponseStream()) )
{
serverResponse = sr.ReadToEnd();
sr.Close();
}
galx = ExtractValue(serverResponse,"GALX","name=\"GALX\" value=\"");
Console.WriteLine(galx);
//Request# 2
string uriWithData = "https://www.google.com/accounts/ServiceLoginBoxAuth";
request = (HttpWebRequest)WebRequest.Create(uriWithData);
request.KeepAlive = true;
request.UserAgent = "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.4) Gecko/2008111217 Fedora/3.0.4-1.fc10 Firefox/3.0.4";
request.Method = "POST";
request.CookieContainer = cookieJar;
string param = string.Format("Email={0}&Passwd={1}&continue={2}&service=analytics&nui=1&dsh=8209101995200094904&GALX={3}&hl=en-US&PersistentCookie=yes","**my email address**",p,"",galx);
byte[] postArr = StrToByteArray(param);
request.ContentType = @"application/x-www-form-urlencoded";
request.ContentLength = param.Length;
Stream reqStream = request.GetRequestStream();
reqStream.Write(postArr,0,postArr.Length);
reqStream.Close();
response = (HttpWebResponse)request.GetResponse();
foreach (Cookie cook in response.Cookies)
{
cookieJar.Add(cook);
}
using (StreamReader sr = new StreamReader(response.GetResponseStream()) )
{
serverResponse = sr.ReadToEnd();
Console.WriteLine(serverResponse);
// Close and clean up the StreamReader
sr.Close();
}
