Not able to use REST API for Service Bus for Windows Server 1.1 (OnPremises)

Question

I am using the Window Server Service Bus 1.1. I am able to generate the OAuth token from the Window Server Service Bus using the following base address

  st         


        

Answer 1

yes it does support it. We are using it.

1. I think your default namespace endpoint is wrong - you dont need .servicebus.windows.net
2. you need to get a token from the sts first using a username and password of a user that has listen or send permissions on service bus.
3. the username and password of the service bus user must be posted in a specific format.
4. Then you need to add the token that is returned into the authorisation header and make your actual send or listen request to the /messages endpoint.

5. This code should do it:

   private const string DefaultNamespace = "https://yoursbserver:9355/servicebusdefaultnamespace";
   private const string QueueEndpoint = "https://yoursbserver:9355/servicebusdefaultnamespace/YourQueueNameOrTopicName/messages/?timeout=60";
   
   private static void Main()
   {
       var token = GetOAuthTokenFromSts(new Uri(DefaultNamespace), "usernamewithpermissiononServiceBus", "password", TimeSpan.FromMinutes(10));
       var messageXml = CreateXml();
       SendMessage(token, messageXml);
   
       Console.WriteLine("Successfully posted message!");
       Console.ReadLine();
   }
   
   private static string CreateMessage()
   {
       return "";
   }
   
   public static string GetOAuthTokenFromSts(Uri namespaceBaseAddress, string userName, string userPassword, TimeSpan timeout)
   {
       const string stsPath = "$STS/OAuth/";
   
       var requestUri = new Uri(namespaceBaseAddress, stsPath);
       var requestContent = GetRequestContent(namespaceBaseAddress, userName, userPassword);
       var request = CreateRequest(timeout, requestUri, requestContent);
       return GetAccessToken(request, requestContent);
   }
   
   private static HttpWebRequest CreateRequest(TimeSpan timeout, Uri requestUri, byte[] requestContent)
   {
       var request = WebRequest.Create(requestUri) as HttpWebRequest;
       request.ServicePoint.MaxIdleTime = 5000;
       request.AllowAutoRedirect = true;
       request.MaximumAutomaticRedirections = 1;
       request.Method = "POST";
       request.ContentType = "application/x-www-form-urlencoded";
       request.ContentLength = requestContent.Length;
       request.Timeout = Convert.ToInt32(timeout.TotalMilliseconds,
                                         CultureInfo.InvariantCulture);
       return request;
   }
   
   private static byte[] GetRequestContent(Uri namespaceBaseAddress, string userName, string userPassword)
   {
       const string clientPasswordFormat = "grant_type=authorization_code&client_id={0}&client_secret={1}&scope={2}";
       var requestContent = string.Format(CultureInfo.InvariantCulture,
                                             clientPasswordFormat, HttpUtility.UrlEncode(userName),
                                             HttpUtility.UrlEncode(userPassword),
                                             HttpUtility.UrlEncode(namespaceBaseAddress.AbsoluteUri));
       return Encoding.UTF8.GetBytes(requestContent);
   }
   
   private static string GetAccessToken(HttpWebRequest request, byte[] requestContent)
   {
       string accessToken;
       using (var requestStream = request.GetRequestStream())
       {
           requestStream.Write(requestContent, 0, requestContent.Length);
       }
   
       using (var response = request.GetResponse() as HttpWebResponse)
       using (var stream = response.GetResponseStream())
       using (var reader = new StreamReader(stream, Encoding.UTF8))
       {
           accessToken = reader.ReadToEnd();
       }
   
       return string.Format(CultureInfo.InvariantCulture, "WRAP access_token=\"{0}\"", accessToken);
   }
   
   private static void SendMessage(string token, string message)
   {
       var webClient = new WebClient();
       webClient.Headers[HttpRequestHeader.Authorization] = token;
       webClient.UploadData(QueueEndpoint, "POST", Encoding.UTF8.GetBytes(message));
   }
