Passport.js 认证成功，根本没有调用

Question

这是我的代码：

passport.use(new localStrategy(
    function(username, password, done) {
        User.findOne({
            username: username
        }, function(err, user) {
            if (err) throw err;
            if (!user) {
                console.log("Unknown User");
                return done(null, false, {
                    message: "Unknown User"
                })
            }
            if (!user.validPassword(password)) {
                console.log("Incorrect password.", password);
                return done(null, false, {
                    message: 'Incorrect password.'
                });
            }

            console.log("User Is detected");
            return done(null, user, {
                message: "User Is detected"

            })

        });
    }
));


router.post('/login',
    passport.authenticate('local', {
        successRedirect: '/',
        failureRedirect: '/users/login',
        failureFlash: true,
        successFlash: 'Welcome!'
    }),
    function(req, res) { // this function not called
        console.log(req)
    });

一切正常，但成功函数未调用，我想收到此消息："welcome"+req.body.username 登录后。

有什么建议吗？谢谢

来自documentation of passport.authenticate()：

the redirect options override the default behavior

在您的示例中，因为您设置了 successRedirect 选项，所以在成功验证后不会调用中间件链中的下一个函数。

如果您希望在重定向到 '/' 之前调用您的函数，那么您应该：

router.post('/login',
    passport.authenticate('local', {
        failureRedirect: '/users/login',
        failureFlash: true
    }),
    function(req, res) {
        // This should show up in your logs:
        console.log('Welcome ' + req.body.username);

        // You can also use a flash to consume after redirect:
        // (provided that you use connect-flash in your app)
        req.flash('info', 'Welcome ' + req.body.username);

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