remoting中server段怎样获取客户端的ip地址？

下面是我在网上找的代码但是我刚学remoting不知道怎么用？请高手指教

Answer 1

Remoting 体系提供了一种插件机制,也就是楼主上面两个Sink类,分别是用于客户端和服务端(必须成对使用),客户端sink通过CallContext.SetData("ClientIPAddress", ip);将IP信息放如SinkData中传递到服务端,在服务端读取相应上下文即可

To 楼主
　　可以很简单得使用RemotingConfiguration.Configure()方法来载入config文件使用插入sink，这个网上的教程很多，具体可以参照Rickie Lee的文章《如何定制Sink扩展.Net Remoting功能》http://www.cnblogs.com/rickie/archive/2004/10/21/54891.html
　　另外还可以自己定制tcpchannel中sinkprovider chain的生成来使用自定义的sink。
　　代码如下：Client：BinaryServerFormatterSinkProvider serverProvider = 
new BinaryServerFormatterSinkProvider();BinaryClientFormatterSinkProvider clientProvider = 
new BinaryClientFormatterSinkProvider();serverProvider.TypeFilterLevel = TypeFilterLevel.Full;IDictionary props = new Hashtable();
props["port"] = 0;System.Runtime.Remoting.Channels.Tcp.TcpChannel tcc = 
new TcpChannel(props,clientProvider,serverProvider);

System.Runtime.Remoting.Channels.ChannelServices.RegisterChannel(tcc);
Hello h = (Hello)System.Activator.GetObject(typeof(Hello),"tcp://localhost:4400/TestRemoting");
System.Console.WriteLine(h.SayHello());
Server：
BinaryServerFormatterSinkProvider serverProvider = 
new BinaryServerFormatterSinkProvider();remotingTest.CClientIPInjectorSinkProvider IPProvider = 
new CClientIPInjectorSinkProvider();

IPProvider.Next = serverProvider;//链接上下一个provider
serverProvider.TypeFilterLevel = TypeFilterLevel.Full;IDictionary props = new Hashtable();
props["port"] = 4400;
props["id"]=string.Empty;

Hello h = new Hello();System.Runtime.Remoting.Channels.Tcp.TcpServerChannel tsc = 
new TcpServerChannel(props,IPProvider);

System.Runtime.Remoting.Channels.ChannelServices.RegisterChannel(tsc);
ObjRef objrefWellKnown = 
System.Runtime.Remoting.RemotingServices.Marshal(h,"TestRemoting");
System.Console.WriteLine("回车结束服务器运行！");
System.Console.ReadLine();＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

并不一定需要成对出现，在ingo rammar的例子里面他使用了
IPAddress IPAddr = (IPAddress)requestHeaders[CommonTransportKeys.IPAddress];
的方法，所以，只要在服务端把这个sink插入进去就可以了。
而CommonTransportKeys中正好含有客户端的IP地址。sink 无需成对，事实上在Client和Server端的sink chain中都不一定是成对反向排列的。
这些都可以在ingo rammar的书里面找到例子。
