Socket.io : Get Client sessionID at any point

rated 0 times [ 45] [ 4] / answers: 1 / hits: 15942 / 11 Years ago, thu, november 7, 2013, 12:00:00

I know how to retrieve the client sessionID when the user connects.

But I'd like to retrieve it at any time, for example when the client clicks on something, I would like to be able to know who clicked, what their sessionID was.

socket.sessionID doesn't work, nor does socket.handshake.sessionID

For example :

I have this express route :

.get('/result/:survey', function(req, res) {

    res.redirect('/result/'+req.params.survey+'/1');

})

Just before the redirection, I'd like to make the user join a socket room, and also get their sessionID. How could I possibly do that ? According to the doc, it would be socket.join('room') but I doubt socketonly represents the connection I have with the client, and not with the other clients. Maybe I'm just having trouble understanding sockets !

As of version 1.0, you get the client's sessionid this way:

var socket = io();

socket.on('connect', function(){

    var sessionid = socket.io.engine.id;

    ...

});
