How to log into a vBulletin forum

First of all, not sythe, second, my function.

Code:

        private void HKPV(string URL, string PDATA, string GDATA, string REFERRER)
        {
            try
            {
                if (GDATA != "" && PDATA == "")
                {
                    URL = URL + GDATA;
                }
                HttpWebRequest req = (HttpWebRequest)WebRequest.Create(URL);
                if (PDATA != "" && GDATA == "")
                {
                    req.Method = "POST";
                    req.ContentType = "application/x-www-form-urlencoded";
                    byte[] buffer = Encoding.ASCII.GetBytes(PDATA);
                    req.ContentLength = buffer.Length;
                    Stream PostData = req.GetRequestStream();
                    PostData.Write(buffer, 0, buffer.Length);
                    PostData.Close();
                }
                // req.Proxy = PROXY;
                if (REFERRER != "")
                {
                    req.Referer = REFERRER;
                }
                HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
                // MessageBox.Show(resp.StatusCode + " : " + req.Referer);
                Stream dataStream = resp.GetResponseStream();
                StreamReader reader = new StreamReader(dataStream);
                String responseFromServer = reader.ReadToEnd();
                html = responseFromServer;
            }
            catch (Exception ex)
            {
                MessageBox.Show(Convert.ToString(ex.Message));
            }
        }

        private void button1_Click(object sender, EventArgs e)
        {
            // Disable some controls
            button1.Enabled = false;
            textBox1.Enabled = false;
            textBox2.Enabled = false;
            checkBox1.Enabled = false;
            // Disabled all controls fine

            // Login initiate
            try
            { // Try to log in, just in case an error happens we have a solution to it
                // Attempt to login with the given details
                // Encrypt the login passwords.
                String hashpass = HashString(textBox2.Text);
                String hashputf = Encoding.UTF8.GetString(
                    Encoding.Convert(
                    Encoding.UTF8, Encoding.UTF8,
                    Encoding.UTF8.GetBytes(hashpass)));
                // End encryption
                HKPV("http://www.someforum.net/login.php?do=login", "?vb_login_username=" + textBox1.Text + "&vb_login_password=" + textBox2.Text + "&securitytoken=guest&do=login&vb_login_md5password=" + hashpass + "&vb_login_md5password_utf=" + hashputf, "", "http://www.someforum.net/index.php");
                textBox3.Text = html;
                // End attempt, success if you have made it this far
            } // End of trying to log in, or an error arose
            catch (Exception ex)
            { // Error reporting
                // If an error occurs we don't want the program to quit, we will just assume that the site is now offline
            } // End error reporting
            finally
            { // After we do all that, do the stuff at the end
                button1.Enabled = true;
                textBox1.Enabled = true;
                textBox2.Enabled = true;
                checkBox1.Enabled = true;
            } // Finished cleanup
            // Login close
        }

so... im guessing i need a new security token each time, i want to do that in the same function, but i really honestly dont know how to parse something out in c# i need to parse

Code:

SESSIONURL = "?s=34095383945340&";

out of the javascript near the top of the page of a vBulletin forum.

 

You don't need to mess with the javascript at all... I have written a vb login function in both php and python just fine with using only a single post request... works just fine.

 

cp,you double posted ;0


Also:
i think cp cleared it up ;p

 

Good job, you're wasting space here in the programming forums.

Can you be more specific as to why you think you need to parse the session ID and where it comes from? As far as I can tell cp is right and it should be way simpler...

 

what am i doing wrong then?

thats the only thing i can think of that would mess up the login. it says invalid password when i enter a valid one.

 

Code:

vb_login_username=[B]USERNAME[/B]&cookieuser=1&vb_login_password=[B]PASSWORD[/B]&s=&do=login&vb_login_md5password=[B]PASSWORDINMD5[/B]&vb_login_md5password_utf=[B]PASSWORDINMD5[/B]

That is what I used in my functions and it works.

 

Well Im trying this on 3.7.4 forums... Doesn't work.
