设置Express

var app = express();

app.configure(function () {
    app.use(express.cookieParser());
    app.use(express.session({secret: 'secret', key: 'express.sid'}));
});


app.get('/', function (req, res) {
    res.sendfile(__dirname + '/index.html');
});

server = http.createServer(app)
server.listen(3000);

设置Socket.IO

io = io.listen(server);

io.set('authorization', function (handshakeData, accept) {

if (handshakeData.headers.cookie) {

handshakeData.cookie = cookie.parse(handshakeData.headers.cookie);

handshakeData.sessionID = connect.utils.parseSignedCookie(handshakeData.cookie['express.sid'],     'secret');

if (handshakeData.cookie['express.sid'] == handshakeData.sessionID) {
  return accept('Cookie is invalid.', false);
}

} else {
    return accept('No cookie transmitted.', false);
} 

accept(null, true);
});
