c# - 没有端点监听 net.pipe

Question

我收到以下错误:

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

我正在从另一个 WCF 调用调用 Windows 服务内的 WCF 自托管服务，如下所示。

                   _host = new ServiceHost(typeof(CalculatorService),
            new Uri[] { new Uri("net.pipe://localhost/PINSenderService") });

        _host.AddServiceEndpoint(typeof(ICalculator),
                new NetNamedPipeBinding(),
                "");

        _host.Open();

        ChannelFactory<ICalculator> factory = new ChannelFactory<ICalculator>(
            new NetNamedPipeBinding(NetNamedPipeSecurityMode.None),
            new EndpointAddress("net.pipe://localhost/PINSenderService"));
        ICalculator proxy = factory.CreateChannel();
        proxy.SendPin(pin);
        ((IClientChannel)proxy).Close();
        factory.Close();

自托管 WCF 服务

 namespace PINSender
 {

    // Define a service contract.    

    public interface ICalculator
    {
        [OperationContract]
        void SendPin(string pin);
    }

    // Implement the ICalculator service contract in a service class.
    public class CalculatorService : ICalculator
    {
        // Implement the ICalculator methods.
        public void  SendPin(string pin)
        {
        }
    }

    public class CalculatorWindowsService : ServiceBase
    {
        public ServiceHost serviceHost = null;
        public CalculatorWindowsService()
        {
            // Name the Windows Service
            ServiceName = "PINSenderService";
        }

        public static void Main()
        {
            ServiceBase.Run(new CalculatorWindowsService());
        }

        // Start the Windows service.
        protected override void OnStart(string[] args)
        {
            if (serviceHost != null)
            {
                serviceHost.Close();
            }

            // Create a ServiceHost for the CalculatorService type and 
            // provide the base address.
            serviceHost = new ServiceHost(typeof(CalculatorService));

            // Open the ServiceHostBase to create listeners and start 
            // listening for messages.
            serviceHost.Open();
        }

        protected override void OnStop()
        {
            if (serviceHost != null)
            {
                serviceHost.Close();
                serviceHost = null;
            }
        }
    }

    // Provide the ProjectInstaller class which allows 
    // the service to be installed by the Installutil.exe tool
    [RunInstaller(true)]
    public class ProjectInstaller : Installer
    {
        private ServiceProcessInstaller process;
        private ServiceInstaller service;

        public ProjectInstaller()
        {
            process = new ServiceProcessInstaller();
            process.Account = ServiceAccount.LocalSystem;
            service = new ServiceInstaller();
            service.ServiceName = "PINSenderService";
            Installers.Add(process);
            Installers.Add(service);
        }

Answer 1

• 确保 IIS 配置为使用 Windows Process Activation Service(WAS):

  1. 从“开始”菜单中选择“控制面板”。
  2. 选择程序，然后选择程序和功能，或者在经典 View 中，选择程序和功能。
  3. 单击打开或关闭 Windows 功能。
  4. 在功能摘要下，点击添加功能。
  5. 展开 Microsoft .NET Framework 3.0(or 3.5) 节点并检查Windows Communication Foundation 非 HTTP 激活功能。

• 确保 Net.Pipe Listener Adapter 服务正在运行:

  1. 开始运行并打开Services.msc
  2. 确保 Net.Pipe Listener Adapter 服务正在运行。

在您的 App.config 中，您已经将 baseAddress 与 http 一起使用，请尝试将其更改为 net.pipe:

  <baseAddresses>
    <add baseAddress="net.pipe://localhost/ServiceModelSamples/service"/>
  </baseAddresses>

参见 NetNamedPipeBinding了解更多详情。

更新:

您需要在 endpoint 中添加 bindingConfiguration，例如:

<endpoint address=""
              binding="netNamedPipeBinding"
              contract="Microsoft.ServiceModel.Samples.ICalculator" 
              bindingConfiguration="Binding1" /> 

并添加实际的bindingConfiguration，例如:

    <bindings>
  <!-- 
        Following is the expanded configuration section for a NetNamedPipeBinding.
        Each property is configured with the default value.
     -->
  <netNamedPipeBinding>
    <binding name="Binding1" 
             closeTimeout="00:01:00"
             openTimeout="00:01:00" 
             receiveTimeout="00:10:00" 
             sendTimeout="00:01:00"
             transactionFlow="false" 
             transferMode="Buffered" 
             transactionProtocol="OleTransactions"
             hostNameComparisonMode="StrongWildcard" 
             maxBufferPoolSize="524288"
             maxBufferSize="65536" 
             maxConnections="10" 
             maxReceivedMessageSize="65536">
      <security mode="Transport">
        <transport protectionLevel="EncryptAndSign" />
      </security>
    </binding>
  </netNamedPipeBinding>
</bindings>
