nodejs会话在本地工作但不在远程服务器上工作

Question

我无法使用passort.js和express.js进行注册和登录，本地工作非常好但是当我在远程服务器上部署应用程序时，登录无法在登录后重定向我。它甚至不会闪现失败消息。

我还注意到，当我在远程服务器上进行注册时，它工作正常，但不会闪烁消息。 req.isAuthenticated（）始终返回false。 我使用MongoDB作为我的数据源

app.use(session({secret : '3T67774A-R649-4D44-9735-43E296ZZ980F', saveUninitialized: true, resave: true}));
app.use(passport.initialize());
app.use(passport.session()); // persistent login sessions
app.use(flash()); // use connect-flash for flash messages stored in session

function isLoggedIn(req, res, next) {
    console.log("Request Authenticated: " + req.isAuthenticated());
    if (req.isAuthenticated())
        return next();
    res.redirect('/login');
}

passport.use('local-login', new LocalStrategy({
    // by default, local strategy uses username and password, we will override with email
    usernameField : 'email',
    passwordField : 'password',
    passReqToCallback : true // allows us to pass in the req from our router (lets us check that a use is logged in or not
}, function(req, email, password, done) {
    if (email)
        email.toLowerCase(); // use lower-case emails to avoid case-sensitive email matching

    // asynchronous
    process.nextTick(function() {
        User.findOne({'local.email' : email}, function(err, user) {
            // if there are any errors, return the error
            if (err) 
                return done(err);

            // if no user found, return the message
            if (!user)
                return done(null, false, req.flash('loginMessage', 'User not found.'));

            if (!user.isValidPassword(password))
                return done(null, false, req.flash('loginMessage', 'Oops! Wrong password.'));

            // return user
            else
                return done(null, user);
        });
    });
}));
