    契約


    新建一個WCF服務類庫項目,在其中添加兩個WCF服務:GameService,PlayerService

    代碼如下:


    [ServiceContract]
    public interface IGameService
    {

    契約

    新建一個WCF服務類庫項目,在其中添加兩個WCF服務:GameService,PlayerService

    代碼如下:

    [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.");
     }
    }

    服務端

    新建一個控制臺應用程序,添加一個類 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監聽已啟動!{0}", _host.Description.Endpoints[0].Address);
      };
      _host.Closed += (s, a) =>
      {
       Console.WriteLine("WCF服務已終止!{0}", _host.Description.Endpoints[0].Name);
      };   
     }
     public void Start()
     {
      Console.WriteLine("正在開啟WCF服務...{0}", _host.Description.Endpoints[0].Name);
      _host.Open();
     }
     public void Stop()
     {
      if (_host != null && _host.State == CommunicationState.Opened)
      {
       Console.WriteLine("正在關閉WCF服務...{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方法中啟動WCF主機

    class Program
     {
      static Program()
      {
       Console.WriteLine("初始化...");
       Console.WriteLine("服務運行期間,請不要關閉窗口。");
       Console.WriteLine();
      }
    
      static void Main(string[] args)
      {
       Console.Title = "WCF主機 x64.(按 [Esc] 鍵停止服務)";
       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();
      }
     }

    服務端配置

    在控制臺應用程序的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>
      </endpoint>
      </service>
      <service name="Wettery.WcfContract.Services.PlayerService" behaviorConfiguration="playerMetadataBehavior">
      <endpoint address="net.tcp://localhost:19998/Wettery/PlayerService" binding="netTcpBinding" contract="Wettery.WcfContract.Services.IPlayerService" bindingConfiguration="netTcpBindingConfig">
       <identity>
       <dns value="localhost" />
       </identity>
      </endpoint>
      </service>
     </services>
     <bindings>
      <netTcpBinding>
      <binding name="netTcpBindingConfig" closeTimeout="00:30:00" openTimeout="00:30:00" receiveTimeout="00:30:00" sendTimeout="00:30:00" transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" listenBacklog="100" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxConnections="100" maxReceivedMessageSize="2147483647">
       <readerQuotas maxDepth="64" maxStringContentLength="2147483647" maxArrayLength="2147483647 " maxBytesPerRead="4096" maxNameTableCharCount="16384" />
       <reliableSession ordered="true" inactivityTimeout="00:30:00" enabled="false" />
       <security mode="Transport">
       <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />
       </security>
      </binding>
      </netTcpBinding>
     </bindings>
     <behaviors>
      <serviceBehaviors>
      <behavior name="gameMetadataBehavior">
       <serviceMetadata httpGetEnabled="True" httpGetUrl="http://localhost:8081/Wettery/GameService/MetaData" />
       <serviceDebug includeExceptionDetailInFaults="True" />
       <serviceThrottling maxConcurrentCalls="1000" maxConcurrentInstances="1000" maxConcurrentSessions="1000" />
      </behavior>
      <behavior name="playerMetadataBehavior">
       <serviceMetadata httpGetEnabled="True" httpGetUrl="http://localhost:8081/Wettery/PlayerService/MetaData" />
       <serviceDebug includeExceptionDetailInFaults="True" />
       <serviceThrottling maxConcurrentCalls="1000" maxConcurrentInstances="1000" maxConcurrentSessions="1000" />
      </behavior>
      </serviceBehaviors>
     </behaviors>
     </system.serviceModel>

    未避免元數據泄露,部署時將HttpGetEnable設為False

    運行控制臺應用程序

    按[ESC]鍵終止服務

    客戶端測試

    服務端運行后,用wcftestclient工具測試,服務地址即behavior中配置的元數據GET地址

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

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