Question

我正在使用登录系统创建一个多人游戏。但是，有一个错误，我不知道如何解决。当我运行我的应用程序时，我收到以下错误：净:: 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'));
});

我只是试图控制日志＆＃34;新的连接尝试＆＃34;当我开始工作但这不起作用。我会感激任何帮助。非常感谢。

首先，我相信您可以更改为此（删除http的额外要求并设置io以收听服务器）：

// Init App
var app = express();
var server = require("http").Server(app);
var io = require("socket.io").listen(server);

如果您的客户端运行在与服务器不同的端口上，我认为您也应该更改导入。否则，那件作品可能没问题。我认为你在var socket = io.connect（）中不需要.o on io。无论如何，我的工作没有它。
