I am attempting to include a custom attribute in a socket.io handshake and transfer it to the socket object upon each connection.
Below is a basic outline of my approach:
var app = express();
var http = require("http").Server(app);
var io = require("socket.io")(http);
io.set('authorization', function(data, callback){
data.foo = 'bar';
callback(null, true);
});
The code above should allow me to access a foo property on the socket.handshake object. However, when I try the following:
io.sockets.on('connection', function (socket) {
console.log(socket.handshake.foo); //This should output bar
});
I receive an undefined value.
