javascript - how to get session id of socket.io client in Client

Question

I want to get session id of client in my socket.io client.

here is my socket.io client :

var socket = new io.Socket(config.host, {port: config.port, rememberTransport: false});
    // when connected, clear out display
    socket.on('connect',function() {
        console.log('dummy user connected');
    });
    socket.on('disconnect',function() {
        console.log('disconnected');
    });
    socket.connect();
    return socket;

I want to get session id of this client , how can i get that ?

Answer 1

Have a look at my primer on exactly this topic.

UPDATE:

var sio = require('socket.io'),
    app = require('express').createServer();

app.listen(8080);
sio = sio.listen(app);

sio.on('connection', function (client) {
  console.log('client connected');

  // send the clients id to the client itself.
  client.send(client.id);

  client.on('disconnect', function () {
    console.log('client disconnected');
  });
});
