c# - 使用 App.Config 的 Windows 服务中的 WCF 命名管道

Question

我很沮丧。好的，这是错误。

There was no endpoint listening at net.pipe://localhost/MyIpcAppToService that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

我终于让 App.Config 文件正常工作，至少没有提示。

当前的 App.Config

我曾经有过:

<endpoint address="http://localhost:8733/MyIpcAppToService" ...

并且在 Windows 服务 OnStart() 事件中:

(以下代码现在已被注释掉，在这个问题帖子中，因为 App.config 文件应该启动 named.pipe。)

public Boolean CreatePipeServer()
{
    string eventText = $"My Service: CommAppToService::CreatePipeServer(IPC App to Service){Environment.NewLine}";
    try
    {
        if (null != this.ServiceParent.HostIpcAppToService)
            this.ServiceParent.HostIpcAppToService = null;

        string pipeBaseAddress = @"net.pipe://localhost/MyIpcAppToService";
        this.ServiceParent.HostIpcAppToService = new ServiceHost(typeof(IpcAppToService), new Uri(pipeBaseAddress));
        NetNamedPipeBinding pipeBinding = new NetNamedPipeBinding()
        {
            //ReceiveTimeout = new TimeSpan(0, 0, 0, 0, Constants.My_TimeoutMsSendReceive),
            //SendTimeout = new TimeSpan(0, 0, 0, 0, Constants.My_TimeoutMsSendReceive),
        };
        this.ServiceParent.HostIpcAppToService.AddServiceEndpoint(typeof(IIpcAppToService), pipeBinding, "MyIpcAppToService");
        this.ServiceParent.HostIpcAppToService.UnknownMessageReceived += HostIpcAppServer_UnknownMessageReceived;
        this.ServiceParent.HostIpcAppToService.Faulted += HostIpcAppServer_Faulted;
        this.ServiceParent.HostIpcAppToService.Closing += HostIpcAppServer_Closing;
        this.ServiceParent.HostIpcAppToService.Closed += HostIpcAppServer_Closed;

        this.IpcAppToService = new IpcAppToService();
        this.IpcAppToService.ApplyDispatchBehavior(this.ServiceParent.HostIpcAppToService);
        this.IpcAppToService.Validate(this.ServiceParent.HostIpcAppToService);
        this.ServiceParent.HostIpcAppToService.Open();

        return true;
    }

我读到该服务将自动启动放置在 App.Config 文件中的服务，实际上是 MyExeName.exe.config 文件。我一直在查看代码，发现它几乎完全相同，所以我将 http:// 替换为 net.pipe://。

可悲的是，旧代码，新代码，代码之间，什么都没有。我一直收到同样的错误。

我使用以下方法从我的桌面应用程序连接到该服务。

public static Boolean ConnectToService()
{
    try
    {
        var callback = new IpcCallbackAppToService();
        var context = new InstanceContext(callback);
        var pipeFactory = new DuplexChannelFactory<IIpcAppToService>(context, new NetNamedPipeBinding(), new EndpointAddress("net.pipe://localhost/MyIpcAppToService"));
        Program.HostIpcAppToService = pipeFactory.CreateChannel();
        Program.HostIpcAppToService.Connect();
        CommAppToService.IsPipeAppToService = true;

        return true;
    }

    catch (Exception ex)
    {
        // Log the exception.
        Errors.LogException(ex);
    }

    return false;
}

不管它值多少钱，这里是:

界面

[ServiceContract(SessionMode = SessionMode.Allowed, CallbackContract = typeof(IIpcCallbackAppToService))]
public interface IIpcAppToService
{
    [OperationContract(IsOneWay = false)]
    [FaultContractAttribute(typeof(IpcAppToServiceFault))]
    UInt16 GetServiceId();

    ...
}

服务:

[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
public class IpcAppToService : IIpcAppToService, IErrorHandler
{
    public static IIpcCallbackAppToService Callback { get; set; } = null;

    public void OpenCallback()
    {
        IpcAppToService.Callback = OperationContext.Current.GetCallbackChannel<IIpcCallbackAppToService>();
    }

    public void CloseCallback()
    {
        IpcAppToService.Callback = null;
    }

    public void SendMessage(string message)
    {
        //MessageBox.Show(message);
    }

    public UInt16 GetServiceId()
    {
        return Constants.My_Id_AppToService;
    }

    ...
}

内部异常 来 self 的桌面 WinForms 应用程序(请注意，没有比这一个更多的内部异常。):

"The pipe endpoint 'net.pipe://localhost/MyIpcAppToService' could not be found on your local machine."

为什么我一直看到这个错误？

第一个答案后更新

我想采取的方向与答案相反，但相同，即服务以 App.config 开始，而 client 使用 C#代码。

可悲的是，我仍然遇到同样的错误。

修改后的客户端 C# 代码:

var callback = new IpcCallbackAppToService();
InstanceContext context = new InstanceContext(callback);
NetNamedPipeBinding binding = new NetNamedPipeBinding();
binding.Security.Mode = NetNamedPipeSecurityMode.None;
EndpointAddress endpointAddress = new EndpointAddress("net.pipe://localhost/MyIpcAppToService");
var pipeFactory = new DuplexChannelFactory<IIpcAppToService>(context, binding, endpointAddress);
Program.HostIpcAppToService = pipeFactory.CreateChannel();
Program.HostIpcAppToService.Connect();
CommAppToService.IsPipeAppToService = true;

该服务没有抛出我可以检测到的异常，因为 EventViewer 是干净的，只有 OnStart() 已成功完成消息。我知道系统会处理 App.config 文件，就像我以前遇到错误时一样，Windows 事件查看器 会一直报错，但现在不会了。

以下是我使用的一些 Microsoft 文档:

netNamedPipeBinding

netNamedPipeBinding2

我试过IO Ninja ，但为 File Stream、Pipe Listener 和 Pipe Monitor 指定 \\.\pipe\MyIpcToService，但是那里没有任何显示，即使当我尝试使用我的 WinForms 桌面应用程序进行连接时，它也会抛出“未找到管道监听器”异常。

可能是什么问题？

Answer 1

<endpoint address="net.pipe://localhost/MyIpcAppToService" binding="wsDualHttpBinding" bindingConfiguration="MyAppToServiceEndpointBinding" contract="MyIpc.IIpcAppToService"/>

确保服务地址的形式(传输协议(protocol))与绑定(bind)类型相同。

• TCP(net.tcp://localhost:8000/myservice) NetTcpBinding
• IPC(net.pipe://localhost/mypipe) NetNamedPipeBinding

• HTTP/Https( http://localhost:8000/myservice )
  Wshttpbinding,Wsdualhttpbinding,basichttpbinding

• WebSocket(ws://localhost:3434) 网络http绑定(bind)

• MSMQ(net.msmq://localhost/private/myservice) NetMsmqBinding

我们应该使用 NetnamedPipeBinding 作为服务地址。请引用我的例子。
