Socket.io: check the status of a connection with the socket id

rated 0 times [ 169] [ 7] / answers: 1 / hits: 29413 / 11 Years ago, thu, may 23, 2013, 12:00:00

I have a socket id of a connection. Can I get the status of that connection, inside the function handler of another one?

Something like this:

io.sockets.on('connection', function(socket) {

    /* having the socket id of *another* connection, I can

     * check its status here.

     */

    io.sockets[other_socket_id].status

}

Is there a way to do so?

For versions higher than 1.0, check Karan Kapoor answer.
For older versions, you can access any connected socket with io.sockets.sockets[a_socket_id], so if you've set a status variable on it, io.sockets.sockets[a_socket_id].status will work.

First you should check if the socket really exists, and it can also be used to check connected/disconnected statuses.

if(io.sockets.sockets[a_socket_id]!=undefined){

  console.log(io.sockets.sockets[a_socket_id]); 

}else{

  console.log(Socket not connected);

}
