我正在使用Mozilla’s client-sessions在我的express.js应用上实现会话,我需要一些帮助。我在我的router.js和app.js中的中间件中有post和gest请求,运行时出现此错误:

  

ReferenceError:未定义requireLogin

// index.js(路由器)

var express = require('express')
  , router = express.Router()
  , user = require('../public/js/models/test.js');



router.get('/profile-header', requireLogin, function (req, res, html) {
  console.log(req.session);
  res.render('templates/profile-header.jade', { title: 'Default' })
});


router.get('/sign-in', function (req, res, html) {
  res.render('templates/sign-in.jade', { title: 'Sign In' })
});


router.get('/blog-home', requireLogin, function (req, res, html) {
  res.render('templates/blog-home.jade', { title: 'Blog' })
});


router.get('/logout', function(req, res) {
  req.session.reset();
  res.redirect('/');
});


router.post('/profile-header', function (req, res, html) {
  user.login(req.body,  function (e, o) {
    if (o) {
      //add session
      req.session.user = o;
      res.redirect('/profile-header');
    } else {
      res.render('templates/sign-in.jade', { error: 'Invalid email or password.' });
    }
  });
});

module.exports = router;

// app.js

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
function requireLogin (req, res, next) {
  if (!req.user) {
    console.log("pd");
    res.redirect('/sign-in');
  } else {
    next();
  }
};


app.use(session({
  cookieName: 'session',
  secret: 'random_string_goes_here',

app.use(bodyParser.json());
app.use(cookieParser());
app.use(stylus.middleware(path.join(__dirname, 'public')));
app.use(express.static(path.join(__dirname, 'public')));
app.use(function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
  next();
});

app.use('/', index);
app.use('/users', users);


app.use(function(req, res, next) {
  if (req.session && req.session.user) {
     user.exist(req.session.username, function  (e, o) {
      if (user) {
        req.user = user;
        delete req.user.user_password; // delete the password from the session
        req.session.user = user;  //refresh the session value
        console.log(req.session);
        res.locals.user = user;
      }
      // finishing processing the middleware and run the route
      next();
    });
  } else {
    next();
  }
});
// listener
app.listen(process.env.PORT || 3000, function () {
	console.log('Listening on http://localhost:' + (process.env.PORT || 3000))
})

module.exports = app;

谢谢你的帮助!

问题在于requireLogin中定义了app.js,但index.js中未定义requireLogin。 我建议在外部服务中移动// auth.service.js exports.requireLogin = function (req, res, next) { ... }; 并在需要时导入/需要它:

index.js

然后在var Auth = require('./auth.service'); .... router.get('/profile-header', Auth.requireLogin, function (req, res, html) { console.log(req.session); res.render('templates/profile-header.jade', { title: 'Default' }) }); 中添加:

@Enumerated(EnumType.STRING)
VehicleType type
