var debug = require('debug')('my-application');
var app = require('../app');
app.set('port', process.env.PORT || 3000);
var server = app.listen(app.get('port'), function() {
debug('Express server listening on port ' + server.address().port);
});
var chat = require('socket.io')(server);
console.log(chat)
io.on('connection', function(socket){
console.log('a user connected');})我用的是express3 在www文件里添加了
var chat = require('socket.io')(server);
console.log(chat)
io.on('connection', function(socket){
console.log('a user connected');})为什么说io未定义呢？？
