我目前开发了几个服务 (WCF) 来使用 TFS 2010。

其中一些使用事件订阅工具，而另一些则通过 sharepoint 门户、小型 wpf 应用程序等消费。

我正在开发一个应用程序来管理另一台服务器中的某些内容，例如向服务器发送 IIS 重置请求，并且我正在使用 wsDualHttpBinding，因此我可以在所有事情发生时通过回调向用户发送进度消息。

但是我什至不能在服务中调用该方法，因为每当通道尝试打开时，无论我的 OpenTimeout 是什么，都会出现超时异常。

这是我的配置（客户端）

合同：

[ServiceContract(SessionMode = SessionMode.Required,
             CallbackContract = typeof(IResetCallback))]
public interface IReset
{
    [OperationContract]
    void ExecutarIISReset();
}

[ServiceContract]
public interface IResetCallback
{
    [OperationContract(IsOneWay = true)]
    void PumpMessage(string message);

    [OperationContract(IsOneWay = true)]
    void PumpResponsiveMessage(ResponsiveMessage message);

    [OperationContract(IsOneWay = true)]
    void PumpLogDeployBEMessage(LogDeployBE message);

    bool Confirmar();

    ServidorModel[] GetServidores();
}

服务（未发布代码，因为问题在到达之前发生）：

[AspNetCompatibilityRequirementsAttribute(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple)] 
public class ResetService : IReset
{
    //Stuff here
}

在提琴手中，我在客户端得到了这个：

7 202 HTTP tfsserver:8080 /DeployService/ResetService.svc 0 private resetman.vshost:9000

我几次得到 202，然后时间过去，超时发生

在服务器上运行小提琴，我一无所获。

可能会发生什么？

编辑：很奇怪，本地主机有效。wsDualHttpBinding 需要特殊权限吗？在“互联网”上没有找到任何东西

由于您正在使用wsDualHttpBinding，因此您的服务器和客户端都需要在配置中指定的端口上可访问。这就是它在您的本地机器上工作的原因，因为您没有任何端口问题。超时与防火墙阻止或您的服务器无法路由回您的客户端一致。

如果您的客户端可以通过添加防火墙或端口转发规则轻松访问，那么wsDualHttpBinding可能仍然适合 - 否则使用 wsDualHttpBinding 可能并不理想。在这种情况下，您可能需要让客户端轮询消息而不是通过回调接收它们（即客户端拉消息而不是通过回调推送它们）

尝试

  • ConcurrencyMode = ConcurrencyMode.Reentrant
  • InstanceContextMode = InstanceContextMode.Single
  • 消除SessionMode.Required

我遇到了同样的问题。我已经通过在客户端应用程序中使用以下代码将绑定配置传递给服务解决了这个问题。这将使您了解如何实现目标。它在我的大多数系统中都对我有用，但在某些系统中仍然存在超时问题。可能原因无法绑定端口。

      Service objService = new Service(objClass, "WSDualHttpBinding_ISendChatService");
            WSDualHttpBinding binding = objService.Endpoint.Binding as WSDualHttpBinding;
            int portNumber = FreeTcpPort();
            string hostName = Dns.GetHostName();
            binding.ClientBaseAddress = new Uri("http://"+Dns.GetHostByName(hostName).AddressList[0].ToString()+":" + portNumber + "/");            
            objService.Start(name);


static int FreeTcpPort()
        {
            TcpListener l = new TcpListener(IPAddress.Loopback, 0);
            l.Start();
            int port = ((IPEndPoint)l.LocalEndpoint).Port;
            l.Stop();
            return port;
        }
