Facebook login Cookies Problem

Ludder231 · 11/03/2015, 16:33

Hi,

ich versuche mich bei Facebook einzuloggen mit Webrequest. Leider funktioniert das nicht und ich bekomme die meldung vom server, dass ich meine cookies im browser aktivieren muss.

Webrequest

Code:

static CookieCollection Cookies = new CookieCollection();
public static string pPost(string URL, string Post)
        {

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);
            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded";
            request.UserAgent = "Mozilla/5.0 (Windows; U; WIndows NT 6.1; ru; rv:1.9.2.3) Gecko/20100401 Firefox/4.0 (.NET CLR 3.5.30729)";
            request.CookieContainer = new CookieContainer();

            foreach (Cookie entry in Cookies)
            {
                request.CookieContainer.Add(entry);
            }

            request.AllowAutoRedirect = true; //carefully with auto
            // Wenn wir request sagen, das wir KEINEN proxy haben, sucht er keinen und die Anfrage geht um einiges schneller
            request.Proxy = null;

            // Post-Daten definieren und abschicken
            string PostData = Post;
            byte[] byteArray = Encoding.Default.GetBytes(PostData);
            request.ContentLength = byteArray.Length;
            Stream DataStream = request.GetRequestStream();
            DataStream.Write(byteArray, 0, byteArray.Length);
            DataStream.Close();

            // Rückgabe holen
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            DataStream = response.GetResponseStream();
            StreamReader reader = new StreamReader(DataStream);
            string ServerResponse = reader.ReadToEnd();
            reader.Close();
            DataStream.Close();

            foreach (Cookie cook in response.Cookies)
            {

                Cookies.Add(cook);
            }


            response.Close();

            return ServerResponse;

        }

        public static string WebRPost(string URL)
        {

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);
            request.Method = "GET";
            request.UserAgent = "Mozilla/5.0 (Windows; U; WIndows NT 6.1; ru; rv:1.9.2.3) Gecko/20100401 Firefox/4.0 (.NET CLR 3.5.30729)";
            request.CookieContainer = new CookieContainer();

            foreach (Cookie entry in Cookies)
            {

                request.CookieContainer.Add(entry);
            }
            request.AllowAutoRedirect = true; //carefully with auto
            request.Proxy = null;
            Stream DataStream = default(Stream);
            // Rückgabe holen
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            DataStream = response.GetResponseStream();
            StreamReader reader = new StreamReader(DataStream);
            string ServerResponse = reader.ReadToEnd();

            foreach (Cookie cook in response.Cookies)
            {

                Cookies.Add(cook);
            }

            reader.Close();
            DataStream.Close();
            response.Close();



            return ServerResponse;

        }

Code:

string bla = Connection.pPost("https://www.facebook.com/login.php?login_attempt=1&lwv=110", "lsd=AVq8j7yX&email=***&pass=****&persistent=1&default_persistent=1&timezone=-60&lgndim=eyJ3IjoxOTIwLCJoIjoxMDgwLCJhdyI6MTkyMCwiYWgiOjEwNDAsImMiOjI0fQ%3D%3D&lgnrnd=050652_nFUt&lgnjs=1446206821&locale=de_DE&qsstamp=W1tbMTUsMzcsNjcsOTMsMTA1LDEwOSwxMjEsMTQ0LDE1MiwxNjcsMTc3LDE4MCwxOTIsMjAwLDIwFRrIl0%3D");

Die lsd und lgndim etc müssen ja vorher ausgelesen werden nicht wahr?
Jedoch funktioniert das auch nicht wenn ich die vorher auslese.

I'm not fluent in German at all, but if I see correctly, you are creating new CookieContainer with each request, you should be reusing the same one to store cookies from a session.

I think more like this, it should do the trick just fine.

Der Kommentar hier ist wichtig und etwas ungenau

WebRequest ist etwas Zickig wenns um Cookies geht, disable das mal und mach die Redirects selbst.

Musst zuerst ein Request auf die Facebook startseite machen dannach auf den login post.

Ahja so wird das trotzdem nicht funktionieren, bei Facebook gibts einige Tokens die generiert werden (Dafür musst du das Javascript analysieren) und die musst du auch nachdem selben algorithmus generieren.

Hab die letzten Tage dran rumhantiert und bin zu dem selben Entschluss gekommen. Aber die tokens kann man sich ja über den Quelltext holen? lgrnd, lgnjs, qsstamp etc.
