How to: .NET client for OSLC RM API and oAuth

I am trying to get the RMCatalog through the OSLC API.

I am using c# (.Net) application and trying to get the details. But I am getting the 401 (Unauthorized) error.

I have the code here:

        static void Main(string[] args)

        {



            WebRequest request = WebRequest.Create("https://server:9443/rm/discovery/RMCatalog");

            request.Proxy = null;

            request.Credentials = new NetworkCredential("User", "Pwd");



            //allows for validation of SSL certificates 

            ServicePointManager.ServerCertificateValidationCallback += new System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications);

            try

            {

                HttpWebResponse response = (HttpWebResponse)request.GetResponse();

                

                var xmlstring = response.Headers;



                //var xmlstring = response.

                Console.WriteLine(xmlstring);

                Console.WriteLine("Hit ENTER to see the response body...");

                Console.ReadLine();



                // Get the stream associated with the response.

                Stream receiveStream = response.GetResponseStream();



                // Pipes the stream to a higher level stream reader with the required encoding format. 

                StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8);



                Console.WriteLine("Response stream received.");

                Console.WriteLine(readStream.ReadToEnd());

                Console.WriteLine("Hit ENTER to see the response body...");

                Console.ReadLine();

                Console.WriteLine(response.ToString());

            }

            catch (Exception ex)

            {

                Console.WriteLine("Error Occured!");

                Console.WriteLine(ex.Message);

            }

            Console.WriteLine("Hit ENTER to exit...");

            Console.ReadLine();

        }



        public static bool AcceptAllCertifications(object sender, System.Security.Cryptography.X509Certificates.X509Certificate certification, System.Security.Cryptography.X509Certificates.X509Chain chain, System.Net.Security.SslPolicyErrors sslPolicyErrors)

        {

            return true;

        }

This works fine when I try to get the CLM catalog at

https://server:9443/ccm/oslc/workitems/catalog

Inspecting further using Fiddler, I could find that the service is expecting oAuth authentication. I tried to find any clear documentation on this, but failed to find anything specific for .NET development.

Can somebody provide some sample code for .NET or provide me details of how one can implement such a .NET client for the OSLC RM API?

Hi Kangkan Goswami,

This is Akki, I am also trying to authenticate the RRC server with Oauth Authentication but no luck so far,
Can you provide me some links and/or the code that you used to authenticate the server using Oauth Authentication.

Regards
Akki

:o

The link in the previous post is broken.

I'm encountering this problem as well. The error that I get is "The remote certificate is invalid according to the validation procedure."

I had code that authenticated successfully in 4.0.1 but no longer authenticates in 4.0.5.
