unable to login to facebook

Hello Everyone :)

My first post here!

I've been struggeling with facebook the whole evening. I'm unable to login with it. It just redirects me to the front site, not replying wrong password or anything.

Here's the code:

Code:

---

            string strUserName = "the%40email.com;// Properties.Settings.Default.facebookemail;
            string strPassword = "password";// Properties.Settings.Default.facebookpassword;

            // Get startpage and login
            string strPostData = String.Format("email={0}&pass={1}&login=Login", strUserName, strPassword);

            request = WebRequest.Create("https://login.facebook.com/login.php?m=&next=http%3A%2F%2Fm.facebook.com%2Fhome.php") as HttpWebRequest;
            request.Method = "POST";
            request.ContentLength = strPostData.Length;
            request.ContentType = "application/x-www-form-urlencoded";
            request.AllowAutoRedirect = true;
            request.CookieContainer = new CookieContainer();
            request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.3) Gecko/20070309 Firefox/2.0.0.3";
           
            ASCIIEncoding encoding = new ASCIIEncoding();
            byte[] loginDataBytes = encoding.GetBytes(strPostData);
            request.ContentLength = loginDataBytes.Length;
            Stream stream = request.GetRequestStream();
            stream.Write(loginDataBytes, 0, loginDataBytes.Length);

            HttpWebResponse webResp = (HttpWebResponse)request.GetResponse();
           

            Stream datastream = webResp.GetResponseStream();
            StreamReader reader = new StreamReader(datastream);
            myFile = File.CreateText("C:\\t.txt");
            myFile.Write(reader.ReadToEnd());

            foreach (Cookie cook in webResp.Cookies)
            {
                MessageBox.Show(cook.Name+" "+cook.Value);
            }

           
            myFile.Close();

Anyone have an idea why?
I've made som wireshark traces and it seems that after login is done it checks the session:

151 11.906270 192.168.1.8 69.63.176.67 HTTP GET /checkcookie.php?r8476606e=&next=http%3A%2F%2Fwww.f acebook.com%2F&refid=9&m_sess=581326628%3A10951669 85 HTTP/1.1

and the cookie sent is:
Cookie: datr=1232160427-4e8b9f0fd2e204bc689bf42bf9660d84400e8024a94ed3d965 381; made_write_conn=1232160427; cur_max_lag=20; m_user=the%40email.com%3A581326628%3AkCjgUPBi6ODv6 aLr\r\n

Thereafter a 301 to facebook.com then sv.facebook.com is received.

Any help would be appreciated!

The behavior from facebook seems right. The URL you are opening processes the login request and then redirects the user to the main page.

What I would do is to get Fiddler and look at what your browser is sending and receiving so that you know what your program should be receiving.

BTW it is generally a bad idea to post cookie data. I don't know how well facebook protects against cookie stealing.

Hello Thantos!

Thank's alot for your reply!

I could not find any differences using Fiddler, i'm afraid. But after changin the connection URL to just https://login.facebook.com it got returned that there was no cookies activated.

Strange, I define the cookies before request is sent. However, with a new cookiecontainer each time. No doubt that it didn't work!

Defining the cookiecontainer on startup solved the problem! Guess that i'm not that sharp (trying to be funny) with c# yet..

Thank you for your help!

Best regards,

hi all!

I'm a blonde! :)
I can't understand your manipulations with C# code :(
If it's not complicated write a complite code))))

I turned over to use facebook mobile.. and browse that :)

Working perfectly ^^

but you inspired me :) thanks !
