I am creating a multiplayer game with login system. However, there is one error, which I don't know how to solve. When I run my app I get the following error: net::ERR_CONNECTION_CLOSED.
这是我的 app.js
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var exphbs = require('express-handlebars');
var expressValidator = require('express-validator');
var flash = require('connect-flash');
var session = require('express-session');
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var mongo = require('mongodb');
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/loginapp');
var db = mongoose.connection;
var routes = require('./routes/index');
var users = require('./routes/users');
// Init App
var app = express();
var http = require('http');
var server = require("http").Server(app);
var io = require("socket.io")(server);
// View Engine
app.set('views', path.join(__dirname, 'views'));
app.engine('handlebars', exphbs({defaultLayout:'layout'}));
app.set('view engine', 'handlebars');
// BodyParser Middleware
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
// Set Static Folder
app.use(express.static(path.join(__dirname, 'public')));
app.use(express.static(__dirname + 'views'));
// Express Session
app.use(session({
secret: 'secret',
saveUninitialized: true,
resave: true
}));
// Passport init
app.use(passport.initialize());
app.use(passport.session());
// Express Validator
app.use(expressValidator({
errorFormatter: function(param, msg, value) {
var namespace = param.split('.')
, root = namespace.shift()
, formParam = root;
while(namespace.length) {
formParam += '[' + namespace.shift() + ']';
}
return {
param : formParam,
msg : msg,
value : value
};
}
}));
// Connect Flash
app.use(flash());
// Global Vars
app.use(function (req, res, next) {
res.locals.success_msg = req.flash('success_msg');
res.locals.error_msg = req.flash('error_msg');
res.locals.error = req.flash('error');
res.locals.user = req.user || null;
next();
});
app.use('/', routes);
app.use('/users', users);
app.set('port', (process.env.PORT || 3000));
io.on('connection', function(socket)
{
console.log('New connection attempt');
});
server.listen(app.get('port'), function(){
console.log('Server started on port '+app.get('port'));
});

当我开始工作时，我只是尝试控制台日志尝试新连接"，但这不起作用. 我将不胜感激.提前非常感谢.
I am just trying to console log "New connection attempt" when I starts working but that doesn't work. I'll be grateful for any help. Thanks a lot in advance.
推荐答案
首先，我相信您可以对此进行更改(删除http的其他要求并设置io来监听服务器):
Firstly, I believe you can change to this (remove the additional require of http and set io to listen to server):
// Init App
var app = express();
var server = require("http").Server(app);
var io = require("socket.io").listen(server);
我认为，如果客户端在与服务器不同的端口上运行，则也应该更改导入.否则，那一块可能很好.我认为您不需要在var socket上的io.connect = io.connect();无论如何，我的工作就是没有它.
If your client-side is running on a different port than your server, you should change your import as well, I think. Otherwise, that piece might be fine. I don't think you need the .connect on io in var socket = io.connect(); Mine is working without it, anyway.
