socket.io和快速3错误

Question

运行app.js时我没有得到任何错误，但我无法获得用户名的JavaScript提示。我只能加载chat.html一切都无法正常工作。 我认为问题可能是：

io = require（'socket.io'）。listen（server）;或

server.listen（80）;

此外，在网络选项卡中，我得到：在红色1659： T = 1394734845750 /socket.io/1 GET （失败） 网:: ERR_CONNECTION_REFUSED socket.io.js。

app.js

var app = require('express')() 
    , server = require('http').createServer(app) 
    , io = require('socket.io').listen(server); 

server.listen(80); 

var fs = require('fs'); 


// routing 
app.get('/', function (req, res) { 
    res.sendfile(__dirname + '/chat.html'); 
}); 

// usernames which are currently connected to the chat 
var usernames = {}; 

function check_key(v) 
{ 
    var val = ''; 

    for(var key in usernames) 
    { 
     if(usernames[key] == v) 
     val = key; 
    } 
    return val; 
} 

io.sockets.on('connection', function (socket) { 

    // when the client emits 'sendchat', this listens and executes 
    socket.on('sendchat', function (data) { 
     // we tell the client to execute 'updatechat' with 2 parameters 
     io.sockets.emit('updatechat', socket.username, data); 
    }); 

    // when the client emits 'adduser', this listens and executes 
    socket.on('adduser', function(username){ 
     // we store the username in the socket session for this client 
     socket.username = username; 
     // add the client's username to the global list 
     usernames[username] = socket.id; 
     // echo to client they've connected 
     socket.emit('updatechat', 'SERVER', 'you have connected'); 
     // echo to client their username 
     socket.emit('store_username', username); 
     // echo globally (all clients) that a person has connected 
     socket.broadcast.emit('updatechat', 'SERVER', username + ' has connected: ' + socket.id); 
     // update the list of users in chat, client-side 
     io.sockets.emit('updateusers', usernames); 
    }); 

    // when the user disconnects.. perform this 
    socket.on('disconnect', function(){ 
     // remove the username from global usernames list 
     delete usernames[socket.username]; 
     // update list of users in chat, client-side 
     io.sockets.emit('updateusers', usernames); 
     // echo globally that this client has left 
     socket.broadcast.emit('updatechat', 'SERVER', socket.username + ' has disconnected'); 
    }); 

    // when the user sends a private msg to a user id, first find the username 
    socket.on('check_user', function(asker, id){ 
     //console.log("SEE: "+asker); console.log(id); 
     io.sockets.socket(usernames[asker]).emit('msg_user_found', check_key(id)); 
    }); 

    // when the user sends a private message to a user.. perform this 
    socket.on('msg_user', function(usr, username, msg) { 
     //console.log("From user: "+username); 
     //console.log("To user: "+usr); 
     //console.log(usernames); 
     io.sockets.socket(usernames[usr]).emit('msg_user_handle', username, msg); 

     fs.writeFile("chat_data.txt", msg, function(err) { 
      if(err) { 
      console.log(err); 
      } /*else { 
      console.log("The file was saved!");

您的服务器侦听端口80，但你的插座连接到端口8008更改这些这么一他们在同一个端口上。
