WCF：没有频道主动收听

Question

我在我的 ASP.NET (C#) 应用程序中创建了一个 WCF 休息服务，当我尝试通过以下网页浏览器浏览它时，它似乎工作正常 本地主机：81/ExternalServices/WS/SPP/REST/SPPService.svc

但是，如果我尝试使用其中一种方法，则会收到以下错误消息： localhost:81/ExternalServices/WS/SPP/REST/SPPService.svc/GetDetails

消息：在“http://MachineName.abc.local:81/ExternalServices/WS/SPP/REST/SPPService.svc/GetDetails”没有积极收听的频道。这通常是由不正确的地址 URI 引起的。确保消息发送到的地址与服务正在侦听的地址匹配。

合同：

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();
    }
}

实施：

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";
        }
    }
}

.SVC 文件 (SPPService.svc)

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

Web.Config

Answer 1

WCF 的一个非常有用的特性是帮助页面。它公开了所有可用的服务以及正确的 URI。

它可以位于：http://MachineName/Service.svc/help。

在我的情况下，它是：localhost:81/ExternalServices/WS/SPP/REST/SPPService.svc/help

这让我看到 Web.Config 文件和 IIS 在端口 82 上使用 HTTPS 绑定。
