自托管服务找不到WCF端点错误

Question

i´m getting an "End point not found" when calling a WCF service. It is a Self-hosted service in a console app.

Here is my code:

IService.cs

namespace ClassLibrary
{
[ServiceContract]
public interface IService
{
    [OperationContract]
    [WebGet]
    string GetMessage(string inputMessage);

    [OperationContract]
    [WebInvoke]
    string PostMessage(string inputMessage);
}

}

Service.cs

namespace ClassLibrary
{
public class Service : IService
{
    public string GetMessage(string inputMessage)
    {
        return "En GetMessage llega " + inputMessage;
    }

    public string PostMessage(string inputMessage)
    {
        return "En PostMessage llega " + inputMessage;
    }
}

}

And the console app:

namespace ConsoleHost
{
class Program
{
    static void Main(string[] args)
    {            
        WebServiceHost host = new WebServiceHost(typeof(Service), new Uri("http://localhost:8000"));
        ServiceEndpoint ep = host.AddServiceEndpoint(typeof(IService), new WebHttpBinding(), "");
        ServiceDebugBehavior db = host.Description.Behaviors.Find<ServiceDebugBehavior>();
        db.HttpHelpPageEnabled = false;

        ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
        smb.HttpGetEnabled = true;
        host.Description.Behaviors.Add(smb);

        host.Open();
        Console.WriteLine("Service is up and running");
        Console.WriteLine("Press enter to quit ");
        Console.ReadLine();
        host.Close();
    }
}

}

There is no config file because it is all in the code.

And the call to the service:

http://localhost:8000/

Any help would be much appreciated. Thanks!

Answer 1

Couple of things. Services hosted with WebServiceHost do not publish metadata, so don't bother trying to get a WSDL with just the service name.

Because its WebGet, you are calling the Get method by default when you enter the service name, so you should supply any needed parameters in the URL. However, this won't work until you declare the form of the request in the contract. Do this by modifying the the WebGet line as follows:

[WebGet(UriTemplate = "{inputMessage}")]

Yes, the attribute property must match the formal parameter of the GetMessage() operation, in this case "inputMessage"

With the service running, enter the following URL into a browser to verify the service works:

http://localhost:8000/hello

You should get something like:

<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">
En GetMessage llega hello</string>

我为您找到了WCF REST自托管400错误请求有效地开发了REST服务，并且有两件事要知道：1-使用WebServiceHost时不需要添加EndPoint和Behavior 2- Rest Services没有公开wsdl，例如，您不能从VS添加服务防护。
