C# OAuth Client Library

csharp-oauth-client-library's Issues

Not authorized, despite correct key and secrets

I am trying to post JSON to WordPress via the new WP-API, using the WP-API-OAUTH plugin.
Also, I'm using .Net 4.6
I have the access token, consumer key, and associated secrets; and I have used them successfully via Java tools.
However, using this tool in my .Net solution, I get a 401.
I am posting JSON as a raw string converted to Bytes.
My code is below. Any ideas what is wrong?

using OAuth;
using OAuth.Base;
using OAuth.Authenticator;
...

        internal void post(string endpoint, string json)
        {
            try
            {
                AccessToken accessToken = new AccessToken("AcceSSToKen", "acCEssToKENsecREt");
                ClientCredentials credentials = new ClientCredentials("CoNSuMeRKEy", "cONSuMERsECreT");
                RequestAuthenticator authenticator = RequestAuthenticatorFactory.GetHmacSha1Authenticator(credentials, accessToken);

                // Create a request using a URL that can receive a post. 
                WebRequest request = WebRequest.Create(endpoint);
                authenticator.SignRequest(request);

                //Set the Method property of the request to POST.
               request.Method = "POST";

                // Create POST data and convert it to a byte array.
                byte[] byteArray = Encoding.UTF8.GetBytes(json);
                // Set the ContentType property of the WebRequest.
                request.ContentType = "application/json";
                // Set the ContentLength property of the WebRequest.
                request.ContentLength = byteArray.Length;

                // Get the request stream.
                Stream dataStream = request.GetRequestStream();
                // Write the data to the request stream.
                dataStream.Write(byteArray, 0, byteArray.Length);
                // Close the Stream object.
                dataStream.Close();

                // Get the response.
                WebResponse response = request.GetResponse();
                // Display the status.
                Console.WriteLine(((HttpWebResponse)response).StatusDescription);

                // Get the stream containing content returned by the server.
                dataStream = response.GetResponseStream();
                // Open the stream using a StreamReader for easy access.
                StreamReader reader = new StreamReader(dataStream);
                // Read the content.
                string responseFromServer = reader.ReadToEnd();
                // Display the content.
                Console.WriteLine(responseFromServer);
                // Clean up the streams.
                reader.Close();
                dataStream.Close();
                response.Close();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }
        }
