c# - 在Azure Service Fabric上设置TCP

我需要设置一个有状态的服务结构应用程序，它监听TCP请求，然后将消息弹出到一个可靠的队列。
有很多关于HTTP和WCF端点的例子，但是对于简单的TCP，我找不到任何东西。
我有这个

 <Endpoints>
  <!-- This endpoint is used by the communication listener to obtain the port on which to
       listen. Please note that if your service is partitioned, this port is shared with
       replicas of different partitions that are placed in your code. -->
  <Endpoint Name="ServiceEndpoint" />

  <!-- This endpoint is used by the replicator for replicating the state of your service.
       This endpoint is configured through a ReplicatorSettings config section in the Settings.xml
       file under the ConfigPackage. -->
  <Endpoint Name="ReplicatorEndpoint" />
  <Endpoint Name="tcpEndpoint" Protocol="tcp" Port="10100"/>
</Endpoints>

我有一个实现名为ServiceManifest.xml

 public class TcpCommunicationListener : ICommunicationListener
{
    private readonly ServiceEventSource eventSource;
    private readonly ServiceContext serviceContext;
    private readonly string endpointName;
    private string listeningAddress;
    private string hostAddress;


    public TcpCommunicationListener(ServiceContext serviceContext, ServiceEventSource eventSource, string endpointName)
    {

        if (serviceContext == null)
        {
            throw new ArgumentNullException(nameof(serviceContext));
        }

        if (endpointName == null)
        {
            throw new ArgumentNullException(nameof(endpointName));
        }

        if (eventSource == null)
        {
            throw new ArgumentNullException(nameof(eventSource));
        }

        this.serviceContext = serviceContext;
        this.endpointName = endpointName;
        this.eventSource = eventSource;
    }

    public Task<string> OpenAsync(CancellationToken cancellationToken)
    {
        var serviceEndpoint = this.serviceContext.CodePackageActivationContext.GetEndpoint(this.endpointName);
        var protocol = serviceEndpoint.Protocol;
        int port = serviceEndpoint.Port;


        //StatefulServiceContext statefulServiceContext = this.serviceContext as StatefulServiceContext;

        this.hostAddress = FabricRuntime.GetNodeContext().IPAddressOrFQDN;

        this.listeningAddress = string.Format(
            CultureInfo.InvariantCulture,
            "{0}://{1}:{2}",
            protocol,
            hostAddress,
            port
           );

        try
        {
            this.eventSource.Message("Starting tcp listener " + this.listeningAddress);

            return Task.FromResult(this.hostAddress);
        }
        catch (Exception ex)
        {
            this.eventSource.Message("Tcp Listener failed to open endpoint {0}. {1}", this.endpointName, ex.ToString());

            throw;
        }
    }

    public Task CloseAsync(CancellationToken cancellationToken)
    {
        throw new NotImplementedException();
    }

    public void Abort()
    {
        throw new NotImplementedException();
    }
}

我还有一个叫做ICommunicationListener的TcpCommunicationListener

internal sealed class ListenerService : StatefulService
{

    public ListenerService(StatefulServiceContext context)
        : base(context)
    {

    }


    protected override IEnumerable<ServiceReplicaListener> CreateServiceReplicaListeners()
    {
        var endpoints = Context.CodePackageActivationContext.GetEndpoints()
                              .Where(endpoint => endpoint.Protocol == EndpointProtocol.Tcp)
                              .Select(endpoint => endpoint.Name);

        return endpoints.Select(endpoint => new ServiceReplicaListener(
            serviceContext => new TcpCommunicationListener(serviceContext, ServiceEventSource.Current, endpoint), endpoint));
    }


    protected override async Task RunAsync(CancellationToken cancellationToken)
    {
        cancellationToken.ThrowIfCancellationRequested();

       //do i spin up a TcpListener here?
    }
}

所以我的问题是，我如何获取正在接收的消息？
我是否必须在我的StatefulService方法中创建一个ListenerService如果是这样，那么在TcpListener中指定端点有什么意义？
或
我需要在RunAsync的ListenerService方法中做些什么吗？

最佳答案

现在，您的通信侦听器代码只在调用OpenAsync时发布uri。您还需要实际开始监听该端点。例如，您可以在那时打开一个Socket。
您也可以将WCF与NetTcpBinding一起使用。
