socket.io - 无法让它工作,在某种轮询调用上有404

我正在尝试使用socket.io设置服务器,结果不好.

我主要关注本指南,虽然它有点过时了:http: //www.williammora.com/2013/03/nodejs-tutorial-building-chatroom-with.html

socket.io问题来了,我不确定它是客户端还是服务器端.它似乎试图不断轮询服务器,但正在回归404.这听起来像socket.io没有运行,但它看起来都没问题.它也可能与路径和"公共"目录有关,但我真的不知道.

服务器

var exec = require( "child_process" ).exec;
var path = require( "path" );
var morgan = require( "morgan" );
var bodyParser = require( "body-parser" );
var _ = require( "underscore" );
var express = require( "express" );
var app = express();
var http = require( "http" ).createServer( app );
var io = require( "socket.io" )( http );

app.set( "ipaddr", "127.0.0.1" );
app.set( "port", 8080 );

//support JSON, urlencoded, and multipart requests
app.use( bodyParser() );

//log the requests using morgan
app.use( morgan() );

//specify the Jade views folder
app.set( "views", __dirname + "/../views" );

//set the view engine to Jade
app.set( "view engine", "jade" );

//specify static content
app.use( express[ "static" ]( "public", __dirname + "/../public" ) ); //using map-access of static so jslint won't bitch

io.on( "connection", function( socket )
{
    console.log( "A user connected." );
});

客户

script( src="js/socket.io.js" )
var socket = io.connect( "http://localhost:8080" );

我从以下位置获取了客户端js文件:node_modules/socket.io/node_modules/socket.io-client/socket.io.js

该路径与我正在使用的教程或者说socket.io所使用的内容不匹配,所以也许这就是问题,但看起来它可能是正确的文件.

这里有什么帮助？

编辑 有关其他信息,这是我的文件夹层次结构:

Webserver/
    my_modules/
        server.js
    node_modules/
        body-parser/
        express/
        jade/
        morgan/
        socket.io/
        underscore/
    public/
        css/
        js/
            server.js
    views/
        index.jade
    index.js
    package.json

my_modules文件夹中的server.js是我在服务器端启动socket.io的地方.js文件夹中的server.js是从网站连接的客户端代码.
