这个问题似乎在网上被仿佛提到，但我查了包括stackoverflow上的许多帖子，还是无法排除400 求指点~~！！

用的是Express 3.3.4 + socket.io 0.9.16 Server端写为

app.js

… var app = express(); var server = require(‘http’).createServer(app).listen(app.get(‘port’)); var io = require(‘socket.io’).listen(server); app.set(‘port’, process.env.PORT || 3000); … app.get(’/find’, function (req, res){ finder.test(req, res,io); }) …

find.js

exports.test = function(req,res,io){

io.sockets.on('connection', function (socket) {
    socket.emit('news', { hello: 'world' });
    socket.on('my other event', function (data) {
        console.log('socket.io log');
        console.log(data);
    });
});

res.render(‘page’); }

… page.jade

… script(src=’/socket.io/socket.io.js’) script. var tokens = location.href.split(’/’); var url = tokens[0]+’//’+tokens[2]; var socket = io.connect(url); socket.on(‘news’,function(data){ console.log(data);

    socket.emit('my other event',{my:'data'});
    })

…

得到的客户端错误。。 GET http://localhost:3000/socket.io/socket.io.js 400 (Bad Request) Uncaught ReferenceError: io is not defined

真诚求助~~~
