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[].Address);
};
_host.Closed += (s, a) =>
{
Console.WriteLine("WCF服务已终止!{0}", _host.Description.Endpoints[].Name);
};
}
public void Start()
{
Console.WriteLine("正在开启WCF服务...{0}", _host.Description.Endpoints[].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[].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">

</service>
<service name="Wettery.WcfContract.Services.PlayerService" behaviorConfiguration="playerMetadataBehavior">

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
