AuthenticationService as REST service...

This month's column answers frequently asked questions about implementing REST.

Does anyone know of a C# code sample demonstrating WCF REST services and console test client with OperationContracts (GET and POST) implementing mutiple paramaters using BASIC authentication? Also, perhaps, using Fiddler as a test client as well? I have searched high and low for something like this, but have not had any success.

After I create a "REST Collection WCF Service" project, it contains one service "service.svc". Can I add multiple services to this project? There must be a way to do so. Otherwise, it does not make sense to create one project for each service.

My question is how to add a new service to an existing "REST Collection WCF Service" project?

Thanks a lot.

Hi ,

I have to call a REST web service method that is deployed remotely on a machine and i use VPN to connect through that url. It works fine when i use the browser to view the output of the web service method but i am unable to get the response in the code as i get an exception. The response status message is OK but when i try to read the response content from the streamreader i get the exception "ex = {"Unable to read data from the transport connection: The connection was closed."}". The content length is -1 in the HttpWebReponse object. Here is the code

        HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://10.0.0.61/metascan_rest/scanner?method=getengineinfo");

        //apply this url when working with the software
       // HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://localhost:1901/metascan_rest/scanner?method=getengineinfo");
       
        request.Method = "GET";
       
        WebResponse res = request.GetResponse();

        string status = ((HttpWebResponse)res).StatusDescription;

        Stream stream = res.GetResponseStream();
        StreamReader reader = new StreamReader(stream);

        try
        {
          //this is where the exception occurs
            string output = reader.ReadToEnd();

Using the rest 4 template.  I have a POST method defined, with an object as a parameter.  REST 4 does a great job of automatically mapping both xml and json posts to the method.  I tested this using an HttpClient test application to build and post xml content and then json content. 

I want to also support a standard form post to the method but am having problems!  

I'd like the same method already accepting and converting both xml and json to also work correctly for a form post.  I am testing this by creating an HttpUrlEncoded form in the test client, adding form name/value pairs that match what the method is expecting, and trying to post it.

However I get a 400 Bad Request.  Here's some example code that is returning a 400 bad request:

            var client = new HttpClient();

            HttpUrlEncodedForm form = new HttpUrlEncodedForm();
            form.Add("Id", "99");
            form.Add("Message", "Message test with 'special' chars #!#");
            form.Add("IpAddress", "192.168.1.1");

            var response = client.Post("<valid-uri-here>", form.CreateHttpContent());
            response.EnsureStatusIsSuccessful();

            client.Disp

Really straightforward but fails.  Ideas why? 

      var client = new HttpClient();

      HttpUrlEncodedForm form = new HttpUrlEncodedForm();
      form.Add("Id", "99"<
