Interface : IService1.cs

namespace WcfService1

    [ServiceContract]
    public interface IService1
    {

        [OperationContract]
        [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json)]
         int GetUserDetails(string strUserID);

    }

}

Here is the another way to go around:

[OperationContract]
[WebGet(UriTemplate = "/GetUserDetails/{strUserID}", 
ResponseFormat = WebMessageFormat.Json)] 
User GetUserDetails(string strUserID);

And User is your custom class holding detail.

[DataContract]
public class User
{
   [DataMemeber]
   public in UserID {get; set;}

   // Remaining attributes here.
}

I don't have much experience with AJAX but I think it should work.

url: 'http://<ipaddress>/WcfService1/Service1.svc/GetUserDetails/101'
type: 'GET',
//contentType: "application/json; charset=utf-8", No need to mention it for GET

回答2:

Change your OperationContract,

    [OperationContract]
    [WebInvoke(UriTemplate = "/GetUserDetails", 
    RequestFormat= WebMessageFormat.Json,   
    ResponseFormat = WebMessageFormat.Json, Method = "POST")] 
    int GetUserDetails(string strUserID);

回答3:

All seems well, Need to check services is not giving 404 not found on browser. If you get 404, you need to install "HTTP-Activation" features under "WCF services" on Windows server 8 or 12.
