var express = require('express');
    var routes = require('./routes');
    var user = require('./routes/user');
    var http = require('http');
    var path = require('path');

var app = express();
    var server = require('http').Server(app);
    var io = require('socket.io')(server);

    server.listen(3000);

    io.sockets.on('connection',function (socket) {
      console.log("Socket connected");
    });

我只是想创建一个连接

并在客户端 –

<script src="public/javascripts/socket.io.js"></script>
     <script>
        var socket = io.connect('http://127.0.0.1:3000');
     </script>

当我打开浏览器时,我在控制台中收到此错误：

GET http://127.0.0.1:3000/socket.io/1/?t=1404410309733 400 (Bad Request) socket.io.js:1659
XHR finished loading: GET "http://127.0.0.1:3000/socket.io/1/?t=1404410309733".

我已经完成了10次这样的工作,但我从来没有这样做过.有谁知道如何修理它？
