Passportjs LocalStartegy未被调用

Question

我正在关注nodejs和expressjs与项目的教程，该项目是用户登录/注册/注销系统。我坚持使用passportjs登录，即使一切都正确，也没有调用LocalStartegy对象，因为我删除了它并记录了一条消息;我知道它没有被调用，因为它没有记录任何东西

这是代码

passport.serializeUser(function(user, done) {
    done(null, user.id);
});

passport.deserializeUser(function(id, done) {
    User.getUserById(id, function(err, user) {
    done(err, user);
   });
});

//local startegy
passport.use(new LocalStrategy({
usernameField: 'login',
passwordField: 'password'
},

function(username, password,done){
    console.log('local startegy called!');
    User.getUserByUsername(username, function(err, user){
        if (err) { return done(err); }
        if(!user){
            console.log('Unknown User');
            return done(null, false, { message: 'Incorrect username.' });
        }

        User.comparePassword(password, user.password, function (err, isMatch) {
            if (err) throw err;
            if(isMatch){
                return done(null, user);
            }else{
                console.log('Invalid password');
                return done(null, false, {message: 'Invalid password'});
            }
        });
    });
}
));

router.post('/login', passport.authenticate('local', {failureRedirect: 
'/users/login', failureFlash: 'Invalid username or password'}), function(req, res){
//runs if the local startegy comes back true
console.log('Authentication successfull...');
req.flash('success', 'You are logged in');
res.redirect('/');
});

这是我的表格

extends layout

block content
    h1 Login
    p Login if you are already a member
    form(method='post', action='/users/login', multipart='urlencoded')
    .form-group
        label Username
        input.form-control(name='username', type='text', 
 placeholder='username')
    .form-group
        label Password
        input.form-control(name='password', type='password', 
 placeholder='password')
    input.btn.btn-default(name='submit', type='submit', value='login')
