socket.io net :: ERR_CONNECTION_CLOSED
我正在用login系统创build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，出现以下错误：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')); }); 我的layout.handlebar

我只是试图控制台日志“新的连接尝试”，当我开始工作，但是不起作用。 我会很感激任何帮助。 非常感谢。
首先，我相信你可以改变这个（删除http的额外要求，并设置io来听服务器）：
// Init App var app = express(); var server = require("http").Server(app); var io = require("socket.io").listen(server);
如果你的客户端运行在不同于你的服务器的端口上，我想你应该改变你的导入。 否则，那件事可能会很好。 我不认为你需要在io上的.connect连接var socket = io.connect（）; 无论如何，我的工作没有它。
