RESTful WCF Web服务的UriTemplate前缀

Question

I have various interfaces (endpoints) in a WCF service host, each for a completely different concern. In a classic soapy web service, I'm able to define a base host address (eg http://myhost.com/ ) and map each interface to a relative URI ( IServiceContract -> service/ , IMaintenanceContract -> maintenance/ ) so I can call them by eg http://myhost.com/service/mymethod .

Now I'm taking my first steps towards a RESTful WCF service using JSON as message format for CRUD web requests and the only thing I see to address an operation is by using the UriTemplate field from WebInvoke (or WebGet ) attribute. Unfortunately, it doesn't seem that I can put this on the interface, just on operation contract methods.

How can I map each interface to a different relative URI ?

Yes, you'll put the base url on the [OperationContract] methods. This is OK though, because you can specify any base url you want. Here is a sample interface that gives you this control.

namespace MyHostApi
{
    [ServiceContract]
    public interface IMyHostApi
    {

        [OperationContract]
        [WebGet(BodyStyle = WebMessageBodyStyle.Bare,
                UriTemplate = "WhateverYouWant/HelloWorld/{name}")]
        string HelloWorld(string format, string name);

    }
}
