Question

大约有30个wcf服务，我们使用wcf路由器来分发来自客户端的请求。 wcf服务由Windows服务托管。当我们将客户端和服务放在同一台计算机上时，客户端和服务可以相互联系。但是，当他们在不同的机器中时，客户端无法联系该服务。我也使用wcftestclient来测试服务，它总是无法添加服务，或者如果我使用添加的客户端项目来测试它，则无法添加服务。如果服务与客户端位于不同的计算机上，则所有单个服务都使用net.pipe和路由器使用net.tcp。我已经在这方面工作了几个星期，问题仍然存在。任何人都可以指出它可能出现的问题吗？非常感谢！

我们有一个设置配置文件供最终用户输入服务服务器地址的名称。端口号也将出现在设置文件中。

    if (!this._issinglecomputer)
        {
            // now add protocol conversion router
            Uri routerbaseaddress = new Uri(publicbaseaddress, "router");
            _routingsvchost = new ServiceHost(typeof(RoutingService), routerbaseaddress);
            _routingsvchostmex = new ServiceHost(typeof (RoutingService), new Uri(routerbaseaddress, "mex"));

            // add the endpoint the router will use to receive service requests
            // we use IDuplexSessionRouter to support a variety of one-way and two-way calls
            _routingsvchost.AddServiceEndpoint(typeof(IDuplexSessionRouter), new NetTcpBinding(SecurityMode.None), "");
            _routingsvchostmex.AddServiceEndpoint(typeof(IDuplexSessionRouter), MetadataExchangeBindings.CreateMexTcpBinding(), "mex");

            // add routing config
            RoutingConfiguration rc = new RoutingConfiguration();

            // loop over all the hosted interfaces and add the entries to the routing table
            foreach (IWcfServiceLibrary sl in wcfServiceLibraries)
            {
                foreach (IWcfServiceConfig config in sl.WcfServiceConfigs)
                {
                    string routedservice = config.WcfService.ServiceClassName.Split('.').Last();
                    var contract = ContractDescription.GetContract(typeof(ISimplexDatagramRouter));
                    var client = new ServiceEndpoint(contract, new NetNamedPipeBinding(NetNamedPipeSecurityMode.None), new EndpointAddress("net.pipe://localhost/" + routedservice));
                    var ea = new EndpointAddress(routerbaseaddress.AbsoluteUri.ToString() + "/" + routedservice);
                    rc.FilterTable.Add(new EndpointAddressMessageFilter(ea, false), new List<ServiceEndpoint>() { client });
                }
            }

            _routingsvchost.Description.Behaviors.Add(new RoutingBehavior(rc));
            _routingsvchostmex.Description.Behaviors.Add(new RoutingBehavior(rc));

            _routingsvchost.Open();
            _routingsvchostmex.Open();


            LoggingService.Logger.Info(string.Format("It is now routing services at {0}", routerbaseaddress.AbsoluteUri));
        }

您可以添加其他服务行为并启用HttpGetEnabled属性。

ServiceMetadataBehavior b = new ServiceMetadataBehavior { HttpGetEnabled = true };
b.HttpGetUrl = myMetadataUri;
routingsvchost.Description.Behaviors.Add(b);

wcf路由器不公开元数据
