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>        </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
