Question

This piece of code doesn’t work; it’s logging in into website which is using https protocol. How to solve this problem? The code stops at GetRequestStream() anytime anywhere saying that protocol violation exception is unhandled..

string username = 'user'; string password = 'pass'; HttpWebRequest request = (HttpWebRequest)WebRequest.Create('https://moje.azet.sk/prihlasenie.phtml?KDE=www.azet.sk%2Findex.phtml%3F'); request.UserAgent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705)';  Console.WriteLine(request.GetRequestStream());  using (StreamWriter writer = new StreamWriter(request.GetRequestStream(), Encoding.ASCII)) {     writer.Write('nick=' + username + '&password=' + password); }  HttpWebResponse response = (HttpWebResponse)request.GetResponse(); //Retrieve your cookie that id's your session //response.Cookies  using (StreamReader reader = new StreamReader(response.GetResponseStream())) {     Console.WriteLine(reader.ReadToEnd()); } 

Answer 1

Set request method to post, before calling GetRequestStream

like

request.Method = 'POST';  using (StreamWriter writer = new StreamWriter(request.GetRequestStream(), Encoding.ASCII)) {     writer.Write('nick=' + username + '&password=' + password); }
