获取WebSocket连接的连接IP

Question

Once I've opened a web socket like so:

m_ws = new WebSocket(127.0.0.1);

Is it possible to get the IP that was just used to open? Something like m_ws._websocket.address ?

I've seen numerous examples but none of them worked as I think they apply to WebSocketServer instances.

Answer 1

Do you use the ws library ?

If you use ws to get IP Connection :

const WebSocket = require('ws');

const wss = new WebSocket.Server({ port: 8080 });

wss.on('connection', function connection(ws, req) {
  const ip = req.connection.remoteAddress;
});
