Closing a socket server side on socket.io?

Problem

I’m pretty sure this is a simple question, but I have no idea where the socket.io docs are and the one at http://labs.learnboost.com/socket.io/ don’t really help.

So let’s say I have a socket.io http server and written a website to connect to it.

  1. How do I provide protection to the server so that unauthorized people(people who connected not through the website) will be blocked/dropped/banned.
  2. How do I end a socket connection on the server side? So If I have
  • io.sockets.on('connection', function (socket) { socket.on('end', function() { var i = global_sockets_list.indexOf(socket); global_sockets_list.splice(i, 1); }); socket.emit('end'); // Doesn't work, just sends data socket.end(); //error });

How do I end a socket connection? (The connect then disconnect above is for testing)

Solution

Try calling:

socket.disconnect('unauthorized');

or

socket.close();

EDIT: You might be able to check the referer header. Look at Socket.io Security Issues for more info.
