I am trying to get the language the user uses in order to serve the right sound files for a playing video, using socket.io and node.js. I am a total beginner with node.js and socket.io. I got the language on client side with "navigator.language" and wanted to send it when connecting/handshaking to socket.io.
var language = navigator.language;
var socket = io.connect('http://localhost:1337', { query: language });
And on server-side:
io.set('authorization', function(handshakeData, cb) {
console.log(handshakeData.query);
cb(null, true);});
But what I get is:
{'en-US': 'undefined', t: '1396002389530'}
I guess the second attribute "t" is the handshake ID that has been added. But how do I access 'en-US'?
My second approach was to use the module "locale" ( https://github.com/jed/locale ), but when I used that, I always got the same language, so I figured that it always finds the SERVER's language. I thought I use it in the request/response handler, when a new client requests the page and sends its http header.
var handler = function(req, res) {
lang = new locale.Locales(req.headers["accept-language"]);
lang=lang.best(supported);
console.log(pf);
}
I hope you get what I am trying to do and maybe know a better solution. Thank you in advance.
You're almost there. Do this:
var socket = io.connect('http://localhost:1337', { lang: language });
Instead of {query: language}
because query is a reserved object.
And you can access this by doing this:
io.set('authorization', function(handshakeData, cb) {
console.log(handshakeData.query.lang);
cb(null, true);});
You can also access it like this:
io.sockets.on('connection', function(socket){
console.log(socket.handshake.query.lang);
});
If you don't want to append language variable to query
then you can access the language by this:
io.sockets.on('connection', function(socket){
console.log(socket.handshake.headers['accept-language']);
});
