无法从Facebook passport获取电子邮件信息

目前,我正在进行一个项目,以存储来自Facebook身份验证的信息,我已经检查过了 Passport-facebook doesn't get email 查看解决方案,下面是我的代码

passport.use(new FacebookStrategy(
  {
    clientID: 'xxxxxxxxxxxxx',
    clientSecret: 'xxxxxxxxxxxxxxxx',
    callbackURL: 'http://1bc600b4.ngrok.io/auth/facebook/callback',
    profileFields: ['id', 'displayName', 'name', 'photos', 'email'],
  },
  (accessToken, refreshToken, profile, done) => {
    console.log(profile);
    models.User.findOne({ where: { facebookID: profile.id } }).then((existinguser) => {
      if (existinguser) {
        // Nothing will happen, the ID already exists
        done(null, existinguser);
      } else {
        models.User.create({
          // email: profile.emails[0].value,
          username: 'hello',
          firstname: profile.name.givenName,
          lastname: profile.name.familyName,
          facebookID: profile.id,
          avatar: `https://graph.facebook.com/${profile.id}/picture?redirect=true&height=470&width=470`,
          avatarThumb: profile.photos[0].value,
          last_login: Date.now(), }).then(user => done(null, user));
      }
    });
  },
));

app.use(passport.initialize());

app.get('/flogin', passport.authenticate(
  'facebook',
  passport.authenticate('facebook', { scope: ['profile', 'email'] }),
));

app.get(
  '/auth/facebook/callback',
  passport.authenticate('facebook', { session: false }),
  (req, res) => {
    res.send('AUTH WAS GOOD!');
  },
);

我不明白为什么我使用这种方式,而电子邮件信息仍然没有显示出来,这让我丢失了很多信息,有谁能给我一个解决这个问题的提示吗?非常感谢。
