如何在java中的客户端套接字程序中知道客户端端口和IP地址

how to get know the client port and ip address in client socket program in java(如何在java中的客户端套接字程序中知道客户端端口和IP地址)

问题描述

我使用套接字在 java 中创建了一个多客户端-服务器通信.我有一个服务器和一个客户端.我想用多个客户端测试我的程序.我计划创建一个动态创建 ip 和端口的模拟器.为此我只想知道如何在套接字程序中设置客户端 ip 和端口.任何人都可以帮助我.. 我使用 InetAddress.getByName 来获取客户端地址.

I created a multiple client- server communication in java using socket. i have a single server and a client. i want to test my program with multiple clients. i m planning to create a simulator which dynamically create ip and port.. for that i just want to know how to set the client ip and port in the socket program. can anyone help me.. i use InetAddress.getByName to get the client address.

 public Socket(Proxy proxy)
  {
     if (proxy != null && proxy.type() == Proxy.Type.SOCKS) 
   { 
    SecurityManager security = System.getSecurityManager();
         InetSocketAddress epoint = (InetSocketAddress) proxy.address();
         if (security != null) {
             if (epoint.isUnresolved())
                epoint = new InetSocketAddress(epoint.getHostName(), epoint.getPort());
            if (epoint.isUnresolved())
                security.checkConnect(epoint.getHostName(),
                                      epoint.getPort());
            else
                security.checkConnect(epoint.getAddress().getHostAddress(),
                                      epoint.getPort());
        }
         impl = new SocksSocketImpl(proxy);
        impl.setSocket(this);
    } else {
        if (proxy == Proxy.NO_PROXY) {
            if (factory == null) {
                impl = new PlainSocketImpl();
                impl.setSocket(this);
             } else
                setImpl();
        } else
            throw new IllegalArgumentException("Invalid Proxy");
     }
}

推荐答案

试试这个

clientString = "Remote client: " + socket.getRemoteSocketAddress().toString().substring(1);
