Difficulties with google authentication

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;

          开发者_StackOverflow社区      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();
                }           

I have no idea an I am pretty sure not many people are going to want to sift through that much code.

One thing that I see at a glance that may be causing problems is that you are playing with the cookies too much.

Create one CookieContainer and just pass it in with each request.

No need to 'transfer' or 'recreate' the container.

Try looking into google accounts api and GBaseService. I believe you will have to set HOSTED_OR_GOOGLE in accountType as Marty has done here in this post.
