ServerSocket + client Socket - 如何获取客户端的IP地址？ [英] ServerSocket + client Socket - how do I get IP address of client?

问题描述

我有一个正在侦听连接的ServerSocket实例。当客户端连接到它时，我想获得连接套接字的IP，但似乎无法找到正确的方法。

I have a ServerSocket instance which is listening for connections. When a client connects to it, I would like to get the IP of the connected socket, but can't seem to find the right method to do so.

public void start() {
    listenSocket = new ServerSocket(port);
    connectionSocket = listenSocket.accept();
}

我试过打电话给以下但没有运气：

I've tried calling the following with no luck:

connectionSocket.getLocalAddress();
connectionSocket.getInetAddress.getHostAddress();
listenSocket.getLocalSocketAddress();

以上都不会返回正确的IP。它们要么返回/ 0：0：0：0：0：0：0：1％0或0.0.0.0。

None of the above return the correct IP. They either return "/0:0:0:0:0:0:0:1%0" or "0.0.0.0".

我做错了什么？

推荐答案

connectionSocket.getRemoteSocketAddress();
