控制台应用程序中托管的WCF REST服务的最低示例

Question

I've just started working with WCF and tried creating a small REST HTTP service. If it is hosted in the IIS, it works fine. However now I am trying to host it in a console application. I've worked through several tutorials but can't get it to work.

My guess is that it is a fairly simple mistake in the Program.cs since the same service works if it is hosted within IIS.

If I try accessing http://localhost:8080/Products/ I get a webpage that says no endpoint found.

Program.cs

Uri baseAddress = new Uri("http://localhost:8080/");

// Create the ServiceHost.
using (WebServiceHost host = new WebServiceHost(typeof(ProductRESTService), baseAddress))
{
     host.Open();

     Console.WriteLine("The service is ready at {0}", baseAddress);
     Console.WriteLine("Press <Enter> to stop the service.");                 
     Console.ReadLine();

     // Close the ServiceHost.
     host.Close();
}

IProductRestService.cs

[ServiceContract]
public interface IProductRESTService
{
    [OperationContract]
    [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "http://localhost:8080/Products/")]
    List<Product> getProductList();

    [OperationContract]
    [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "http://localhost:8080/Product/{id}/")]
    Product getProduct(string id);
}

ProductRestService.cs

[ServiceBehavior(AddressFilterMode = AddressFilterMode.Any)]
public class ProductRESTService : IProductRESTService
{
    public Product getProduct(string id)
    {
        return Products.Instance.GetProduct(Convert.ToInt32(id));
    }

    public List<Product> getProductList()
    {
        return Products.Instance.ProductList;
    }
}

The Product and Products classes are here http://pastebin.com/FRFxsWBU but I doubt that they are relevant.

Thanks!

Ok, I found a solution myself. The mistake was really rather stupid: In the IProductRestService.cs the UriTemplates are supposed to be templates not URIs themselves.

Now I have this:

    [OperationContract]
    [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "/Products/")]
    List <Product> getProductList();

    [OperationContract]
    [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "/Product/{id}/")]
    Product getProduct(string id);

And it works as expected.
