不是应该socket去set和get吗

//服务端 var io = require(‘socket.io’).listen(80);   io.sockets.on('connection’, function (socket) {     socket.on('set nickname’, function (name) {         socket.set('nickname’, name, function () { socket.emit(‘ready’); });     });       socket.on('msg’, function () {         socket.get('nickname’, function (err, name) {             console.log('Chat message by ', name);         });     }); });

//客户端

<script> var socket = io.connect('http://localhost');   socket.on('connect', function () {     socket.emit('set nickname', confirm('What is your nickname?'));     socket.on('ready', function () {         console.log('Connected !');         socket.emit('msg', confirm('What is your message?'));     }); }); </script>
