WCF REST can not parse Request Body - wcf

Question

I have a struggling time with WCF REST to parse request body.
My problem:
POST method https://{Service}/X/Y? Z= 0000000
Body Request: {"id":"id"}
My code:
[ServiceContract]
public interface IService
{
[OperationContract]
[WebInvoke(Method = "POST",
BodyStyle = WebMessageBodyStyle.Bare,
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
UriTemplate = "/X/{y}?Z={z}")
]
string GetRequest(string y, string z, Request request);
}
public class Service : IService
{
public string GetRequest(string y, string z, Request request)
{
//Do sth
}
[DataContract]
public class Request
{
[DataMember]
[JsonProperty("id")]
public String Id { get; set; }
}
The problem that I have is that y and z has data and they are correct BUT id in request is null. I expected to be "id".
I searched a lot in the internet and I found Stream solution which is not easily to follow in this case.
I am wondering if anyone has a clever idea to do this.

Take a look on this version
The Service
namespace ServiceTest
{
internal class Program
{
private static WebServiceHost _service;
private static void Main()
{
_service = new WebServiceHost(typeof (Service));
Console.WriteLine("The service has started");
_service.Open();
Console.ReadKey();
}
}
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
public sealed class Service : IService
{
public string GetRequest(string y, string z, Request request)
{
Console.WriteLine("Y: {0}, Z: {1}, request: {2}", y, z, request);
return "Ok";
}
}
[ServiceContract]
public interface IService
{
[OperationContract]
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json, UriTemplate = "/X/{y}?Z={z}")]
string GetRequest(string y, string z, Request request);
}
[DataContract]
public sealed class Request
{
[DataMember]
public string Id { get; set; }
public override string ToString()
{
return string.Format("Id: {0}", Id);
}
}
}
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<services>
<service name="ServiceTest.Service">
<host>
<baseAddresses>
<add baseAddress="http://localhost:9090/webhost" />
</baseAddresses>
</host>
<endpoint binding="webHttpBinding" contract="ServiceTest.IService" />
</service>
</services>
</system.serviceModel>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
</configuration>
The Client
internal class Program
{
private static void Main(string[] args)
{
var client = new HttpClient();
var request = new Request {Id = "Nelibur"};
var result = client.PostAsync("http://localhost:9090/webhost/X/Y?Z=2000", CreateContent(request)).Result;
Console.WriteLine(result.Content.ReadAsStringAsync().Result);
Console.ReadKey();
}
private static StringContent CreateContent<T>(T value)
{
using (var stream = new MemoryStream())
{
var serializer = new DataContractJsonSerializer(typeof (T));
serializer.WriteObject(stream, value);
string content = Encoding.UTF8.GetString(stream.ToArray());
return new StringContent(content, Encoding.UTF8, "application/json");
}
}
}
Raw request:
POST http://localhost:9090/webhost/X/Y?Z=2000 HTTP/1.1
Content-Type: application/json; charset=utf-8
Host: localhost:9090
Content-Length: 16
Expect: 100-continue
Connection: Keep-Alive
{"Id":"Nelibur"}
You can try to use the request in for example Fiddler
