我正在尝试将用户登录模块添加到节点中的现有应用程序。它为每个模块使用单独的路由文件，并使用一个主路由文件来使用最终在server.js中使用的所有子路由 当我尝试将护照实例传递给用户路径时，由于未定义护照，因此会给出错误。这是我的应用程序代码和结构：
app
views
user
index.ejs
login.ejs
signup.ejs
profile.ejs
routes
docs
index.js
user

const flash = require('connect-flash')
const session = require('express-session')
const routes = require('./routes/')
const port = process.env.PORT || 3000;
app.use(express.static(path.join(__dirname, 'public')));
require('./config/passport')(passport);
app.use(bodyParser.urlencoded({
extended: true
}));
app.use(cookieParser());
app.use(bodyParser.json());
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, 'views'));
app.use(session({ secret: '********' }));
app.use(passport.initialize());

app.use(flash());
app.use('/', routes)(app,passport);
const server = app.listen(port, function(){
console.log('Server listening on port '+port);

请在这里建议我做错了什么。感谢

您应该在调用它们时将main和user路由包装起来运行它们的逻辑，并在结束时返回准备好的路径：
路由/ index.js
module.exports = function(app, passport) {
const mainroute = require('express').Router()
/* ---- other existing routes included ---- */
const r_docs = require('./docs');
const r_user = require('./user'); /*my custom route*/
/* ---- all other routes ---- */
mainroute.use('/docs', r_docs);
mainroute.use('/user', r_user)(app, passport); /*my custom route*/
mainroute.get('/', function(req, res) {
res.render('home');
});
return mainroute;
};
路由/用户/ index.js
module.exports = function(app, passport) {
const express = require('express');
const router = express.Router();
router.get('/', function(req, res) {
res.render('user/index.ejs');
});
router.get('/login', function(req, res) {
res.render('user/login.ejs', {
message: req.flash('loginMessage')
});
});
// process the login form
router.post('/login', passport.authenticate('local-login', {
successRedirect: '/profile',
failureRedirect: '/login',
failureFlash: true
}));
router.get('/signup', function(req, res) {
res.render('user/signup.ejs', {
message: req.flash('signupMessage')
});
});
router.post('/signup', passport.authenticate('local-signup', {
successRedirect: '/profile',
failureRedirect: '/signup',
failureFlash: true
}));
router.get('/profile', isLoggedIn, function(req, res) {
res.render('user/profile.ejs', {
user: req.user
});
});
router.get('/logout', function(req, res) {
req.logout();
res.redirect('/');
});
function isLoggedIn(req, res, next) {
if (req.isAuthenticated())
return next();
res.redirect('/');
}
return router;
};

您需要在user / index.js的顶部要求它。简单地说：
var passport = require('passport');
然后确保用户已通过身份验证：
router.get('/some/path', isLoggedIn, function(req, res) {
var user = req.user;
});
function isLoggedIn(req, res, next) {
if (req.isAuthenticated())
return next();
res.redirect('/');
}
