示例

下面的代码示例演示如何使用 HttpServerChannel 对象设置远程处理服务器及其客户端。 该示例包含三个部分：

• 服务器

• 客户端

• 服务器和客户端使用的远程对象

下面的代码示例演示了一个服务器。

#using <System.dll>
#using <System.Runtime.Remoting.dll>
#using "common.dll"
using namespace System;
using namespace System::Runtime::Remoting;
using namespace System::Runtime::Remoting::Channels;
using namespace System::Runtime::Remoting::Channels::Http;

int main()
{
   // Create the server channel.
   HttpServerChannel^ serverChannel = gcnew HttpServerChannel( 9090 );
   
   // Register the server channel.
   ChannelServices::RegisterChannel( serverChannel );
   
   // Display the channel's scheme.
   Console::WriteLine( L"The channel scheme is {0}.", serverChannel->ChannelScheme );
   
   // Display the channel's URI.
   Console::WriteLine( L"The channel URI is {0}.", serverChannel->GetChannelUri() );
   
   // Expose an object for remote calls.
   RemotingConfiguration::RegisterWellKnownServiceType(
      RemoteObject::typeid, L"RemoteObject.rem", WellKnownObjectMode::Singleton );
   
   // Get the channel's sink chain.
   IServerChannelSink^ sinkChain = serverChannel->ChannelSinkChain;
   Console::WriteLine( L"The type of the server channel's sink chain is {0}.", sinkChain->GetType() );
   
   // See if the channel wants to listen.
   bool wantsToListen = serverChannel->WantsToListen;
   Console::WriteLine( L"The value of WantsToListen is {0}.", wantsToListen );
   
   // Parse the channel's URI.
   array<String^>^ urls = serverChannel->GetUrlsForUri( L"RemoteObject.rem" );
   if ( urls->Length > 0 )
   {
      String^ objectUrl = urls[ 0 ];
      String^ objectUri;
      String^ channelUri = serverChannel->Parse( objectUrl,  objectUri );
      Console::WriteLine( L"The object URI is {0}.", objectUri );
      Console::WriteLine( L"The channel URI is {0}.", channelUri );
      Console::WriteLine( L"The object URL is {0}.", objectUrl );
   }

   
   // Wait for the user prompt.
   Console::WriteLine( L"Press ENTER to exit the server." );
   Console::ReadLine();
   Console::WriteLine( L"The server is exiting." );
}

using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Http;

public class Server
{
    public static void Main(string[] args)
    {
        // Create the server channel.
        HttpServerChannel serverChannel = new HttpServerChannel(9090);

        // Register the server channel.
        ChannelServices.RegisterChannel(serverChannel);

        // Display the channel's scheme.
        Console.WriteLine("The channel scheme is {0}.",
            serverChannel.ChannelScheme);

        // Display the channel's URI.
        Console.WriteLine("The channel URI is {0}.",
            serverChannel.GetChannelUri());

        // Expose an object for remote calls.
        RemotingConfiguration.RegisterWellKnownServiceType(
            typeof(RemoteObject), "RemoteObject.rem",
            WellKnownObjectMode.Singleton);

        // Get the channel's sink chain.
        IServerChannelSink sinkChain = serverChannel.ChannelSinkChain;
        Console.WriteLine(
            "The type of the server channel's sink chain is {0}.",
            sinkChain.GetType().ToString());

        // See if the channel wants to listen.
        bool wantsToListen = serverChannel.WantsToListen;
        Console.WriteLine(
            "The value of WantsToListen is {0}.",
            wantsToListen);

        // Parse the channel's URI.
        string[] urls = serverChannel.GetUrlsForUri("RemoteObject.rem");
        if (urls.Length > 0)
        {
            string objectUrl = urls[0];
            string objectUri;
            string channelUri =
                serverChannel.Parse(objectUrl, out objectUri);
            Console.WriteLine("The object URI is {0}.", objectUri);
            Console.WriteLine("The channel URI is {0}.", channelUri);
            Console.WriteLine("The object URL is {0}.", objectUrl);
        }

        // Wait for the user prompt.
        Console.WriteLine("Press ENTER to exit the server.");
        Console.ReadLine();
        Console.WriteLine("The server is exiting.");
    }
}

下面的代码示例演示此服务器的客户端。

#using <System.dll>
#using <System.Runtime.Remoting.dll>
#using "common.dll"
using namespace System;
using namespace System::Runtime::Remoting;
using namespace System::Runtime::Remoting::Channels;
using namespace System::Runtime::Remoting::Channels::Http;

void main()
{
   // Create the channel.
   HttpClientChannel^ channel = gcnew HttpClientChannel;
   
   // Register the channel.
   ChannelServices::RegisterChannel( channel );
   
   // Register as client for remote object.
   WellKnownClientTypeEntry^ remoteType = gcnew WellKnownClientTypeEntry(
      RemoteObject::typeid,L"http://localhost:9090/RemoteObject.rem" );
   RemotingConfiguration::RegisterWellKnownClientType( remoteType );
   
   // Create an instance of the remote object.
   RemoteObject^ service = gcnew RemoteObject;
   
   // Invoke a method on the remote object.
   Console::WriteLine( L"The client is invoking the remote object." );
   Console::WriteLine( L"The remote object has been called {0} times.", service->GetCount() );
}

using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Http;

public class Client
{
    public static void Main(string[] args)
    {
        // Create the channel.
        HttpClientChannel channel = new HttpClientChannel();

        // Register the channel.
        ChannelServices.RegisterChannel(channel);

        // Register as client for remote object.
        WellKnownClientTypeEntry remoteType = new WellKnownClientTypeEntry(
            typeof(RemoteObject),"http://localhost:9090/RemoteObject.rem");
        RemotingConfiguration.RegisterWellKnownClientType(remoteType);

        // Create an instance of the remote object.
        RemoteObject service = new RemoteObject();

        // Invoke a method on the remote object.
        Console.WriteLine("The client is invoking the remote object.");
        Console.WriteLine("The remote object has been called {0} times.",
            service.GetCount());
    }
}

下面的代码示例演示服务器和客户端使用的远程对象。

using namespace System;
using namespace System::Runtime::Remoting;

// Remote object.
public ref class RemoteObject: public MarshalByRefObject
{
private:
   static int callCount = 0;

public:
   int GetCount()
   {
      callCount++;
      return (callCount);
   }

};

using System;
using System.Runtime.Remoting;

// Remote object.
public class RemoteObject : MarshalByRefObject
{
    private int callCount = 0;

    public int GetCount()
    {
        callCount++;
        return(callCount);
    }
}

注解

通道跨远程处理边界传输消息 (例如，在应用程序域) 上的计算机之间传输消息。 类 HttpServerChannel 使用 HTTP 协议传输消息。

.NET Framework远程处理基础结构使用通道来传输远程呼叫。 当客户端调用远程对象时，该调用将序列化为由客户端通道发送并由服务器通道接收的消息。 然后对其进行反序列化和处理。 任何返回的值都由服务器通道传输并由客户端通道接收。

若要在服务器端执行其他消息处理，可以指定 的 IServerChannelSinkProvider 实现，通过该实现传递处理 HttpServerChannel 的所有消息。

接受 HttpServerChannel 以二进制或 SOAP 格式序列化的消息。

HttpServerChannel对象具有关联的配置属性，可以在运行时通过调用静态RemotingConfiguration.Configure方法) (配置文件中设置这些属性，或通过将集合传递给IDictionaryHttpServerChannel构造函数) 以编程方式 (。 有关这些配置属性的列表，请参阅 的文档 HttpServerChannel。
