So I'm making a small application for a vbulleting site but need to authenticate the user when he opens my application, I have code to send login request, but I am unsure how to actually check if the login was successful.
This is what I have so far:
public string Login(string username, string password)
{
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(MPGHLogin);
string cookie = "";
string values = "vb_login_username=" + username + "&vb_login_password=" + password
+ "&securitytoken=guest&"
+ "cookieuser=checked&"
+ "do=login";
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = values.Length;
CookieContainer a = new CookieContainer();
req.CookieContainer = a;
System.Net.ServicePointManager.Expect100Continue = false;
using (StreamWriter writer = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII))
{
writer.Write(values);
}
HttpWebResponse c = (HttpWebResponse)req.GetResponse();
foreach (Cookie cook in c.Cookies)
{
cookie = cookie + cook.ToString() + ";";
}
if (c.StatusCode != HttpStatusCode.OK)
return "FAILED_CONNECTION";
return cookie;
}
But how can I check if the authentication was successful?
For other people that may have the same problem, I completely forgot about checking the respone stream for a login successful message, so below is the full code.
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(MPGHLogin);
req.AllowAutoRedirect = true;
string cookie = "";
string values = "vb_login_username=" + username + "&vb_login_password=" + password
+ "&securitytoken=guest&"
+ "cookieuser=checked&"
+ "do=login";
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = values.Length;
CookieContainer a = new CookieContainer();
req.CookieContainer = a;
System.Net.ServicePointManager.Expect100Continue = false;
StreamWriter writer = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
writer.Write(values);
writer.Close();
req.Timeout = 5000;
HttpWebResponse c;
try {
c = (HttpWebResponse)req.GetResponse(); // da response
} catch(Exception e)
{
MessageBox.Show(e.Message, "Web Exception");
return "WebException";
}
foreach (Cookie cook in c.Cookies)
{
cookie = cookie + cook.ToString() + ";";
}
Stream resp = c.GetResponseStream();
StreamReader reader = new StreamReader(resp, Encoding.GetEncoding(c.CharacterSet));
string response = reader.ReadToEnd();
reader.Close();
reader.Dispose();
if (response.Contains("Thank you for logging in, " + username))
{
c.Dispose();
return cookie;
}
else
return "FAILED_AUTH";
