Remoting 的服务器侧如何获知Client的IP地址

[eaglet]

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?

[htu]

我也想知道，帮你顶以下

[califord]

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

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;
}
}
}

关注！

我感觉发消息的时候IP地址也是消息的一部分就简单了

[moonshineidolon]

去搜索一下探针

[wuluhua2003]

ip地址可以手工改，还是获取mac地址比较好
