simple json call from c#

string URL = "http://www.blah.com/";

                    string urlParameters = “?v=1”;

                   

                    HttpClient client = new HttpClient();

                    client.BaseAddress = new Uri(URL);

                    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

                    HttpResponseMessage response = client.GetAsync(urlParameters).Result; 

                    if (response.IsSuccessStatusCode)

                    {

                        string dataObjects = response.Content.ReadAsStringAsync().Result;

                        var jss = new JavaScriptSerializer();

                        var dict = jss.Deserialize<Dictionary<string, dynamic>>(dataObjects);

                        foreach (Dictionary<string, object> x in dict["items"])

http 404 error on wcf rest service httpget

i was getting because of the length of the querystring

basicHttpBinding cannot handle

application/octet so streams are a problem

REST Clients

I had a situation where I needed to pass security in  a HTTP header - Postman worked while SOAPUI didn't

rest service working on local but not on server

may just need a bindingConfiguration that handles https

<security mode="Transport">

WebHost failed to process a request- specifies multiple request body parameters to be serialized without any wrapper elements.

instead of changing the code i changed the behavior from webHttp to enableWebScript

Endpoints using 'UriTemplate' cannot be used with 'System.ServiceModel.Description.WebScriptEnablingBehavior'.

change behaviours

400 Bad Request

will happen when you call a REST service using the wrong address (the address behavior that is not rest)

Internet Explorer cannot display the webpage

Easy way to test WCF and REST services - use WebServiceHost class

  static void Main(string[] args)

        {

            WebServiceHost host = new WebServiceHost(typeof(Service), new Uri("http://localhost:8000/"));

            try

            {

                ServiceEndpoint ep = host.AddServiceEndpoint(typeof(IService), new BasicHttpBinding(), "");

                host.Open();

                using (ChannelFactory<IService> cf = new ChannelFactory<IService>(new BasicHttpBinding(), "http://localhost:8000"))

                {

                   // cf.Endpoint.Behaviors.Add(new bas WebHttpBehavior());

                    IService channel = cf.CreateChannel();

                    herby h = channel.getHerby();

                    Console.WriteLine("   i: {0}", h.i );

                    Console.WriteLine("   s: {0}", h.s);

                    Console.WriteLine("");

                    Boris b = channel.getBoris();

                    Console.WriteLine("   i: {0}", h.i);

                    Console.WriteLine("   s: {0}", h.s);

                    Console.WriteLine("");

                }

                Console.WriteLine("Press <ENTER> to terminate");

                Console.ReadLine();

              

                host.Close();

            }

            catch (CommunicationException cex)

            {

                Console.WriteLine("An exception occurred: {0}", cex.Message);

                host.Abort();

            }

        }

Good analogy

about REST

HTTP Error 411. The request must be chunked or have a content length

add Content-Length:  header
