(C#) HTTPS Windows Integrated AuthenticationThis example pertains to running on the Windows operating system only. It provides guidance on how to send HTTP requests using the current logged-on Windows user credentials. This is where NTLM/Negotiate authentication is used, but the login/password credentials are not explicitly provided by the application, but are implicitly provided based on the Windows logged-on user (i.e. the Windows account for the running process).
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.Http http = new Chilkat.Http(); // Chilkat implements the NTLM protocol directly, which is how it can be used on non-Windows systems. // However, Chilkat can also optionally use Microsoft's SSPI (see https://docs.microsoft.com/en-us/windows/desktop/secauthn/ssp-packages-provided-by-microsoft) // to allow for Windows Integrated Authentication. // Setting the HTTP Login equal to the empty string, and the Password equal to the keyword "default" // will cause Chilkat to use the Microsoft SSPI w/ integrated authentication. http.Login = ""; http.Password = "default"; // We can also explicitly indicate that NTLM or Negotiate authentication is to be used: http.NegotiateAuth = true; // Set various properties unrelated to authentication.. // Automatically follow redirects. http.FollowRedirects = true; // Give verbose logging in the LastErrorText (in case there are errors) http.VerboseLogging = true; // Optionally log the exact session to a file (for debugging) http.SessionLogFilename = "c:/someDir/session.txt"; // Perhaps you wish to be seen as a browser on Mac OS X.. http.UserAgent = "Mozilla/5.0 (Windows NT; Windows NT 6.1; en-GB) AppleWebKit/534.6 (KHTML, like Gecko) Chrome/7.0.500.0 Safari/534.6"; // Note: If the result of authentication is to set Cookies that are used in subsequent requests, // then make sure Chilkat both saves and sends cookies: http.SaveCookies = true; http.SendCookies = true; http.CookieDir = "memory"; // Send a GET request to a URL, using Windows Integrated Authentication... string responseStr = http.QuickGetStr("https://somewhere.net/api/user"); if (http.LastMethodSuccess != true) { Debug.WriteLine(http.LastErrorText); return; } Debug.WriteLine("response status code = " + Convert.ToString(http.LastStatus)); Debug.WriteLine("response header:"); Debug.WriteLine(http.LastHeader); Debug.WriteLine("----"); Debug.WriteLine(responseStr); |
