Question

现在已经和这个问题搏斗了2天:)会感激一些帮助。

我正在尝试使用passportjs + sqlite + sequelize构建快速身份验证，

1）当我把路线放在app.use(passport.session())以上时，登录不起作用

2）当我把路线放在passport.session以下时，应用程序无法获取路线

App.js 



   --- normal includes
app.use(cookieParser());
app.use(session({
  secret: 'ilovescotchscotchyscotchscotch',
  resave: true,
  saveUninitialized: true
}));

var passport = require('passport');

app.use(passport.initialize());

app.use(passport.session());

var router = require('./routes/index')(passport);

app.use('/', router);

var initPassport  = require('./passp.js');
initPassport(passport);

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

// expose this function to our app using module.exports

    var User = require('./dbCon.js');
    passport.serializeUser(function(user, done) {
        done(null, user.dataValues.id);
    });

路线档案

module.exports = function(passport){

router.get('/', function(req, res, next) {
    res.render('index', { title: 'Express' });
});

router.get('/error', function(req, res, next) {
    res.render('error', { title: 'Express' });
});

router.get('/admin', function(req, res, next) {
    res.render('admin', { title: 'Express' });
});


router.post('/signup', function(req, res, next) {
    passport.authenticate('local-signup', function(err, user, info) {
        if (err) { return next(err); }
        // Redirect if it fails
        if (!user) { return res.redirect('/'); }
        req.logIn(user, function(err) {
            if (err) { return next(err); }
            // Redirect if it succeeds
            return res.render('admin');
        });
    })(req, res, next);
});

router.post('/login', function(req, res, next) {
    passport.authenticate('local-login', function(err, user, info) {
        if (err) { return next(err); }
        // Redirect if it fails
        if (!user) { return res.redirect('/'); }
        req.logIn(user, function(err) {
            if (err) { return next(err); }
            // Redirect if it succeeds
            return res.render('admin');
        });
    })(req, res, next);
});

return router

} 请帮我！谢谢！

.then()收到结果作为第一个参数，而不是error

试一试：

// used to deserialize the user
passport.deserializeUser(function(id, done) {
    User.findOne({where : {id : id}})
    .then(function(user) {
        done(null, user);
    })
    .catch(function(err){
        done(err, null);
    });
});
