POperforming http methods using windows application in c#
text
Body
copied!<p>There are many sites which call a script upon form submit and pass in parameters using HTTP POST or GET, using a web debugger i have found the parameters being passed. Now i wish to do the same thing through my Windows Application in C#. How can i achieve such a functionality?</p> <p>I am currently using HttpWebRequest and HttpWebResponse class in C#. But it is a pain as i have to write explicit code for each page i try to load and work. For Example i am trying to pass username and password to a php page and taking the response, which will send a cookie and a page in return, based on which i identify if the user has logged in or not.</p> <pre><code>HttpWebRequest loginreq = createreq("http://www.indyarocks.com/mobile/index.php"); String logintext = "username=" + TxtUsrname.Text + "&pass=" + TxtPasswd.Password + "&button.x=0&button.y=0"; loginreq.ContentLength = logintext.Length; StreamWriter writerequest = new StreamWriter(loginreq.GetRequestStream()); writerequest.Write(logintext); writerequest.Close(); HttpWebResponse getloginpageresponse = (HttpWebResponse)loginreq.GetResponse(); cookie = getloginpageresponse.Cookies[0]; BinaryFormatter bf1 = new BinaryFormatter(); Stream f1 = new FileStream("E:\\cookie.dat", FileMode.OpenOrCreate); bf1.Serialize(f1, cookie); f1.Close(); string nexturl = getloginpageresponse.Headers[HttpResponseHeader.Location]; StreamReader readresponse = new StreamReader(getloginpageresponse.GetResponseStream()); if (nexturl == "p_mprofile.php") { MessageBox.Show("Login Successful"); GrpMsg.IsEnabled = true; } else if (nexturl == "index.php?msg=1") { MessageBox.Show("Invalid Credentials Login again"); } </code></pre> <p>This is my createreq class</p> <pre><code> private HttpWebRequest createreq(string url) { HttpWebRequest temp = (HttpWebRequest)WebRequest.Create(url); temp.Method = "POST"; temp.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.0.04506; .NET CLR 3.5.21022; FDM)"; temp.KeepAlive = true; temp.ContentType = "application/x-www-form-urlencoded"; temp.CookieContainer = new CookieContainer(); temp.AllowAutoRedirect = false; return temp; } </code></pre> <p>Am i on the right track? Is there any better way to do it?</p>
