WCF：没有频道主动收听

Question

I created a WCF rest service in my ASP.NET (C#) application, and it seems to be working fine when I try to browse to it via web browser at the following localhost:81/ExternalServices/WS/SPP/REST/SPPService.svc

However, if I try to hit one of its methods, I get the below error message: localhost:81/ExternalServices/WS/SPP/REST/SPPService.svc/GetDetails

Message : There was no channel actively listening at ' http://MachineName.abc.local:81/ExternalServices/WS/SPP/REST/SPPService.svc/GetDetails '. This is often caused by an incorrect address URI. Ensure that the address to which the message is sent matches an address on which a service is listening.

Contract :

namespace ABC.WebApp.ExternalServices.WS.SPP.REST
{
    [ServiceContract]
    public interface ISPPService
    {
        [OperationContract]
        [WebInvoke(Method = "POST", UriTemplate = "GetProductionDetail")]
        string GetProductionDetail(Stream data);

        [OperationContract]
        [WebGet]
        string GetDetails();
    }
}

Implementation :

namespace ABC.WebApp.ExternalServices.WS.SPP.REST
{
    [AspNetCompatibilityRequirements(RequirementsMode =  AspNetCompatibilityRequirementsMode.Allowed)]
    public class SPPService : ISPPService
    {
        public string GetProductionDetail(Stream xmlRequest)
        {
            return "hello";
        }

        public string GetDetails()
        {
            return "hello2";
        }
    }
}

The .SVC File (SPPService.svc)

<%@ ServiceHost Service = "ABC.WebApp.ExternalServices.WS.SPP.REST.SPPService" Language="C#" %>

Web.Config

<system.serviceModel>

  <service name="ABC.WebApp.ExternalServices.WS.Disb.Rest.DisbService" behaviorConfiguration="defaultBehaviour">

Answer 1

A very helpful feature of WCF is the help page. It exposes all available services along with the correct URIs.

It can be located at: http://MachineName/Service.svc/help .

In my situation, it was: localhost:81/ExternalServices/WS/SPP/REST/SPPService.svc/help

This led me to see that the Web.Config file along with IIS were using HTTPS binding on port 82.
