我使用express和socket.io http://socket.io/get-started/chat/
创建了一个node.js聊天应用我在本地服务器上成功运行聊天应用程序。我必须在我的VPS中部署它。有什么步骤？ 我在我的VPS＆amp;中安装了node express和socket.io。将我的所有内容上传到服务器中。
我在puTTY中运行命令$node index.js。它说听3000端口。
但是当我去那个网址时它会收到错误http：//******.in/socket.io/socket.io.js 404（Not Found）
但它在我的localhost中运行得非常好。
index.js
var app = require('express')();
var url = require('url');
var server = require('http').Server(app);
var io = require('socket.io')(server);
var numUsers=0;
var users={};
app.get('/', function(req, res){
res.sendFile(__dirname + '/index.html');
});
server.listen(3000, function(){
console.log('listening on *:3000');
});
io.sockets.on('connection',function(socket){
console.log('connected');
socket.on('send message',function(data,callback){
var msg=data.trim();
if(msg.substr(0,1)=='p'){
msg=msg.substr(1);
var ind=msg.indexOf(' ');
if(ind!=-1){
var name=msg.substr(0,ind);
var msg=msg.substr(ind+1);
if(name in users){
users[name].emit=('private',{msg:msg,nick:socket.nickname});
console.log('private message');
}else{
callback('Enter your name');
}
}else{
callback('Enter private message');
}
}else{
console.log('message'+data);
io.sockets.emit('new message',{msg:msg,nick:socket.nickname});
}
});
function updateNickNames(){
io.sockets.emit('usernames',Object.keys(users));
}
function countUsers(){
io.sockets.emit('users count',{userscount:numUsers});
}
socket.on('new user',function(data,callback){
if(data in users){
callback(false);
}else{
++numUsers;
callback(true);
socket.nickname=data;
users[socket.nickname]=socket;
updateNickNames();
countUsers();
}
});
socket.on('disconnect',function(data){
if(!socket.nickname) return;
delete users[socket.nickname];
--numUsers;
updateNickNames();
countUsers();
io.sockets.emit('remove user',{username:socket.nickname});
});
});
