WCF绑定netTcpBinding寄宿到控制台应用程序

契约

新建一个WCF服务类库项目,在其中添加两个WCF服务:GameService,PlayerService

代码如下:

[ServiceContract]
public interface IGameService
{
    [OperationContract]
    Task<string> DoWork(string arg);
}
public class GameService : IGameService
{
    public async Task<string> DoWork(string arg)
    {
        return await Task.FromResult($"Hello {arg}, I am the GameService.");
    }
}
[ServiceContract]
public interface IPlayerService
{
    [OperationContract]
    Task<string> DoWork(string arg);
}
public class PlayerService : IPlayerService
{
    public async Task<string> DoWork(string arg)
    {
        return await Task.FromResult($"Hello {arg}, I am the PlayerService.");
    }
}

服务端

新建一个控制台应用程序,添加一个类 ServiceHostManager

public interface IServiceHostManager : IDisposable
{
    void Start();
    void Stop();
}

public class ServiceHostManager<TService> : IServiceHostManager
    where TService : class
{
    ServiceHost _host;

    public ServiceHostManager()
    {
        _host = new ServiceHost(typeof(TService));
        _host.Opened += (s, a) => {
            Console.WriteLine("WCF监听已启动!{0}", _host.Description.Endpoints[0].Address);
        };
        _host.Closed += (s, a) =>
        {
            Console.WriteLine("WCF服务已终止!{0}", _host.Description.Endpoints[0].Name);
        };            
    }
    public void Start()
    {
        Console.WriteLine("正在开启WCF服务...{0}", _host.Description.Endpoints[0].Name);
        _host.Open();
    }
    public void Stop()
    {
        if (_host != null && _host.State == CommunicationState.Opened)
        {
            Console.WriteLine("正在关闭WCF服务...{0}", _host.Description.Endpoints[0].Name);
            _host.Close();
        }
    }
    public void Dispose()
    {
        Stop();
    }

    public static Task StartNew(CancellationTokenSource cancelTokenSource)
    {
        var theTask = Task.Factory.StartNew(() =>
        {
            IServiceHostManager shs = null;
            try
            {
                shs = new ServiceHostManager<TService>();
                shs.Start();
                while (true)
                {
                    if (cancelTokenSource.IsCancellationRequested && shs != null)
                    {
                        shs.Stop();
                        break;
                    }
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex);
                if (shs != null)
                    shs.Stop();
            }
        }, cancelTokenSource.Token);

        return theTask;
    }
}

在Main方法中启动WCF主机

class Program
    {
        static Program()
        {
            Console.WriteLine("初始化...");
            Console.WriteLine("服务运行期间,请不要关闭窗口。");
            Console.WriteLine();
        }

        static void Main(string[] args)
        {
            Console.Title = "WCF主机 x64.(按 [Esc] 键停止服务)";
            var cancelTokenSource = new CancellationTokenSource();
            ServiceHostManager<WcfContract.Services.GameService>.StartNew(cancelTokenSource);
            ServiceHostManager<WcfContract.Services.PlayerService>.StartNew(cancelTokenSource);
            while (true)
            {
                if (Console.ReadKey().Key == ConsoleKey.Escape)
                {
                    Console.WriteLine();
                    cancelTokenSource.Cancel();
                    break;
                }
            }
            Console.ReadLine();
        }
    }

服务端配置

在控制台应用程序的App.config中配置system.serviceModel

<system.serviceModel>
    <services>
      <service name="Wettery.WcfContract.Services.GameService" behaviorConfiguration="gameMetadataBehavior">
        <endpoint address="net.tcp://localhost:19998/Wettery/GameService" binding="netTcpBinding" contract="Wettery.WcfContract.Services.IGameService" bindingConfiguration="netTcpBindingConfig">
          <identity>
            <dns value="localhost" />
          </identity>

          <serviceThrottling maxConcurrentCalls="1000" maxConcurrentInstances="1000" maxConcurrentSessions="1000" />
        </behavior>
        <behavior name="playerMetadataBehavior">

          <serviceThrottling maxConcurrentCalls="1000" maxConcurrentInstances="1000" maxConcurrentSessions="1000" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

未避免元数据泄露,部署时将HttpGetEnable设为False

运行控制台应用程序

按[ESC]键终止服务

客户端测试

服务端运行后,用wcftestclient工具测试,服务地址即behavior中配置的元数据GET地址

http://localhost:8081/Wettery/GameService/MetaData
http://localhost:8081/Wettery/PlayerService/MetaData
