Question

我做错了什么？它总是重定向到失败页面，但我无法调试。

// passport
var passport = require('passport'),
    LocalStrategy = require('passport-local').Strategy,
    User = require('./models/user.js').Model;

passport.use(new LocalStrategy({
    usernameField: 'email',
    passwordField: 'password'
  },
  function(username, password, done) {
    User.findOne({ username: username }, function(err, user) {
      console.log('entrou');
      if (err) { return done(err); }
      if (!user) {
        return done(null, false, { message: 'Incorrect username.' });
      }
      if (!user.validPassword(password)) {
        return done(null, false, { message: 'Incorrect password.' });
      }
      return done(null, user);
    });
  }
));


// login
app.get('/login', user.login);
app.post('/login',
  passport.authenticate('local', { 
    successRedirect: '/',
    failureRedirect: '/login' 
  })
);

我还有一些与passport.js无法进行身份验证有关的问题。所以这就是它对我有用的方式：

/**
 * Local authentication strategy
 *
 */
passport.use('local', new LocalStrategy(function(username, password, done) {
  //async code waits until next()
  process.nextTick(function() {
    //searches the database for the user
    //that matches the username|e-mail and password provided
    models.User.checkCredentials(username, password, function(err, user) {
      if (err) {
        return done(err);
      }

      //user is not found
      if (!user) {
        return done(null, false, {message: 'Unknown user ' + username});
      }

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

登录用户

app.post('/login', function(req, res, next) {
  passport.authenticate('local', function(err, user, info) {
    if (err) { return next(err); }
    // if user is not found due to wrong username or password
    if (!user) {
      return res.render('login', {
        //you can send a message to your view
        message: 'Invalid username or password'
      });
    }
    //passport.js has a logIn user method
    req.logIn(user, function(err) {
      if (err) { return next(err); }

      return res.redirect('/');
    });
  })(req, res, next);
});

PassportJS无法验证
