Remoting 的服务器侧如何获知Client的IP地址

Question

我在服务器侧想获知连接服务器的客户端的IP地址,以校验其身份,不知如何实现?

Answer 1

string ipAddress = System.Web.HttpContext.Current.Request.UserHostAddress

Answer 2

使用下面的sinkprovider类和sink类。
sing System;
using System.Runtime.Remoting.Channels;
using System.Net;
using System.Runtime.Remoting.Messaging;
using System.Collections;
using System.IO;namespace remotingTest
{ public class CClientIPInjectorSink : BaseChannelObjectWithProperties,IServerChannelSink
{
private IServerChannelSink _nextSink;
    
public CClientIPInjectorSink(IServerChannelSink nextSink)
{
_nextSink = nextSink;
}
 
public void AsyncProcessResponse(IServerResponseChannelSinkStack sinkStack,
object state, 
IMessage msg, 
ITransportHeaders headers,
Stream stream) 
{
//get the client's ip address, and put it in the call context. 
//This value will be extracted later so we can determine the actual
//address of the client.
try
{
IPAddress IPAddr = (IPAddress)headers[CommonTransportKeys.IPAddress];
//====================================
Console.WriteLine(IPAddr.ToString());
//====================================
CallContext.SetData("ClientIP", IPAddr);
}
catch{} //forward to stack for further processing
sinkStack.AsyncProcessResponse(msg, headers,stream);
} public Stream GetResponseStream(IServerResponseChannelSinkStack sinkStack,
object state,
IMessage msg,
ITransportHeaders headers)
{
return null;
} public IServerChannelSink NextChannelSink
{
get
{
return _nextSink;
}
} public ServerProcessing ProcessMessage(IServerChannelSinkStack sinkStack,
IMessage requestMsg,
ITransportHeaders requestHeaders,
Stream requestStream,
out IMessage responseMsg,
out ITransportHeaders responseHeaders,
out Stream responseStream)
{
//get the client's ip address, and put it in the call context. 
//This value will be extracted later so we can determine the actual
//address of the client.
try
{
IPAddress IPAddr = (IPAddress)requestHeaders[CommonTransportKeys.IPAddress];
//===================================
Console.WriteLine(IPAddr.ToString());
CallContext.SetData("ClientIP", IPAddr);
}
catch{} //pushing onto stack and forwarding the call
sinkStack.Push(this,null); ServerProcessing srvProc = 
_nextSink.ProcessMessage(sinkStack,requestMsg,
requestHeaders, requestStream, 
out responseMsg,out responseHeaders, 
out responseStream);
if(srvProc == ServerProcessing.Complete)
{
//TODO - implement post processing
}
return srvProc;
}
}
}

using System;
using System.Runtime.Remoting.Channels;
using System.Net;
using System.Runtime.Remoting.Messaging;
using System.Collections;
using System.IO;namespace remotingTest
{ public class CClientIPInjectorSinkProvider : IServerChannelSinkProvider
{ private IServerChannelSinkProvider _nextProvider; public CClientIPInjectorSinkProvider(){} public CClientIPInjectorSinkProvider(IDictionary properties, 
ICollection providerdata){} public IServerChannelSink CreateSink(IChannelReceiver channel)
{
//create other sinks in the chain
IServerChannelSink nextSink = _nextProvider.CreateSink(channel);
return new CClientIPInjectorSink(nextSink);
}
public void GetChannelData(IChannelDataStore channelData)
{
//not needed
} public IServerChannelSinkProvider Next
{
get
{
return _nextProvider;
}
set
{
_nextProvider = value;
}
}
}
}

Answer 5

ip地址可以手工改，还是获取mac地址比较好
