C# Restful Service Using WebInvoke POST

I am developing a Restful service in C# and working well when I use

[OperationContract]
    [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Xml, BodyStyle =     
WebMessageBodyStyle.Wrapped, UriTemplate = "json/?id={id}")]
    string jdata(string id);

and my corrsponding function implementation is:

public string json(string id)
{
 return "You Typed : "+id;
}

Up to here all works well, but when I change WenInvoke Method="POST" I have to face a "Method NOT Allowed.";

[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Xml, BodyStyle = 
WebMessageBodyStyle.Wrapped, UriTemplate = "json/?id={id}")]
    string jdata(string id);

You get "Method not allowed" because you are reaching the Uri "json/?id={id}" via GET instead of POST. Check this with your client (you didn't mention how you call this resource). Please give some further details how you are trying to use your web service in client. Is is .Net client?

To test your API I recommend using Fiddler - when you can explicitly specify whether to use GET or POST before sending an http request: enter image description here

Another thing is, you might have unwittingly used "json" as Uri, but defined ResponseFormat as WebMessageFormat.Xml. Isn't it a little confusing for the client? Maybe you wanted to return JSON back? In that case, I would recommend using Json in both - request and response:

[WebInvoke(Method = "POST", UriTemplate = "/ValidateUser", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]

 [OperationContract]
        [WebInvoke(Method="POST",
            ResponseFormat = WebMessageFormat.Json,
            BodyStyle = WebMessageBodyStyle.Bare,
             UriTemplate = "json")]
        string jdata(string id);

This is how your contract should look like and then in client

WebRequest httpWebRequest =
             WebRequest.Create(
               url);
            httpWebRequest.Method = "POST";
string json = "{\"id\":\"1234"\}"

 using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
            {
                streamWriter.Write(json);
            }
            httpWebRequest.Timeout = 1000000;

            WebResponse webrespon = (WebResponse)httpWebRequest.GetResponse();

            StreamReader stream = new StreamReader(webrespon.GetResponseStream());
            string result = stream.ReadToEnd();

             Console.Out.WriteLine(result);

Above is just something i use to test my services. Hope it helps.
