Finding Login URL of a Web Page
I've recently been developing a C# application for myself and a friend of mine and I've basically managed to code everything except one feature that basically gets the amount of credits that you have on your account from a site called getref.com.
To do this I need to either login the account via a Login URL by means of the WebClient Object in the .Net Framework which would look something like:
I can then simply parse the string strRes to find the amount of credits.
WebClient myClient = new WebClient();
string strRes = myClient.DownloadString("http://ww.getref.com/processlogin.asp?&txtUsername=<username>&txtPassword=<password>&login=Logon");
I can also try to login via an HttpWebRequest:
Just like the other example I can then simply parse the string strRes to find the amount of credits as well.
string User = "******";
string Pass = "******";
string url = "http://ww.getref.com/processlogin.asp";
string pdata = "&txtusername=" + User + "&txtpassword=" + Pass + "&login=Logon";
string strRes = SendWebRequest(url, pdata, 8, "");
private static string SendWebRequest(string Url, string PData, int Interval, string Referer)
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(Url);
if (PData != "")
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
byte arrbytes = Encoding.ASCII.GetBytes(PData);
req.ContentLength = arrbytes.Length;
Stream reqStream = req.GetRequestStream();
reqStream.Write(arrbytes, 0, arrbytes.Length);
if (Referer != "")
req.Referer = Referer;
req.Timeout = Interval * 0x3e8;
HttpWebResponse httpresponse = (HttpWebResponse)req.GetResponse();
StreamReader _streamreader = new StreamReader(httpresponse.GetResponseStream());
My problem is that of finding the correct login Url to login or that of creating the right HttpWebRequest for logging in. :/
Does anyone know what I'm doing wrong?
Are my HTTP Headers incorrect?
Am I crafting my query properly?
Sorry if I'm doing a lot of stupid mistakes. I'm very inexperienced when it comes to web dev thats why I decided to ask the pros xD.
Thanks a lot.
