Question

我正在创建一个多人游戏，我也有登录系统。所以我有我的app.js和users.js。在users.js中存储了有关用户的数据，我希望将该信息发送到我的app.js.

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 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')));

// 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);

server.listen(process.env.PORT || 3000, function(){
  console.log("Express server listening on port %d in %s mode", this.address().port, app.settings.env);
});

我的 users.js

var express = require('express');
    var router = express.Router();
    var passport = require('passport');
    var LocalStrategy = require('passport-local').Strategy;

    var User = require('../models/users');

    // Register
    router.get('/register', function(req, res){
        res.render('register');
    });

    // Login
    router.get('/login', function(req, res){
        res.render('login');
    });

    //Register User
    router.post('/register', function(req, res){
        var name = req.body.name;
        var email = req.body.email;
        var username = req.body.username;
        var password = req.body.password;
        var password2 = req.body.password2;

    // Validation
        req.checkBody('name', 'Name is required').notEmpty();
        req.checkBody('email', 'Email is required').notEmpty();
        req.checkBody('email', 'Email is not valid').isEmail();
        req.checkBody('username', 'Username is required').notEmpty();
        req.checkBody('password', 'Password is required').notEmpty();
        req.checkBody('password2', 'Passwords do not match').equals(req.body.password);


        var errors = req.validationErrors();

        if(errors)
        {
            res.render('register',{
                errors:errors
            });

        } else 
        {
            var newUser = new User({
                name: name,
                email:email,
                username: username,
                password: password
            });

            User.createUser(newUser, function(err, user){
                if(err) throw err;
                console.log(user);
            });

            req.flash('success_msg', 'You are registered and can now login');

            res.redirect('/users/login');
        }
    });

    passport.use(new LocalStrategy(
      function(username, password, done) {
       User.getUserByUsername(username, function(err, user){
        if(err) throw err;
        if(!user){
            return done(null, false, {message: 'Unknown User'});
        }

        User.comparePassword(password, user.password, function(err, isMatch){
            if(err) throw err;
            if(isMatch){
                return done(null, user);
            } else {
                return done(null, false, {message: 'Invalid password'});
            }
        });
       });
      }));

    passport.serializeUser(function(user, done) {
      done(null, user.id);
    });

    passport.deserializeUser(function(id, done) {
      User.getUserById(id, function(err, user) {
        done(err, user);
      });
    });

    router.post('/login',
      passport.authenticate('local', {successRedirect:'/', failureRedirect:'/users/login',failureFlash: true}),
      function(req, res) {
        res.redirect('/');
      });       

    router.get('/logout', function(req, res){
        req.logout();

        req.flash('success_msg', 'You are logged out');

        res.redirect('/users/login');
    });


    module.exports = router;

提前多多感谢。

更新的 index.js

var express = require('express');
var router = express.Router();

   // Get Homepage
   router.get('/', ensureAuthenticated, function(req, res){
   res.render('index');
 });

  function ensureAuthenticated(req, res, next){
     if(req.isAuthenticated()){
      return next();
     } else {
        //req.flash('error_msg','You are not logged in');
        res.redirect('/users/login');
     }
  }

 module.exports = router;

您已经在加载＆＃39;假设users.js实际位于/routes/users.js，您的用户已加入您的应用。 app.js中的行var users = require('./routes/users')正在导入用户路由的导出。

然后，您正在为您的应用程序使用这些路由，其中第一个参数为/users app.use('/users',users)的任何路径。

如果您在将用户数据输入或移出应用程序时遇到特殊问题，则需要编辑问题以提供更多详细信息。

将用户的信息从users.js发送到app.js
