Question

我正在使用ExpressJS和PassportJS的Facebook策略尝试在认证回调上执行一些条件重定向，当某些属性丢失时应该调用它。

我的用户架构：

var UserSchema = new Schema({
  id: ObjectId,
  uid: String,
  facebookToken: String,
  username: String,
  password: String,
  salt: String,
  firstName: String,
  lastName: String,
  email: String,
  birthday: Date,
  gender: String,
  location: String,
  phone: Number,
  verifiedPhone: Boolean,
  interests: {
    culture: Boolean,
    food: Boolean,
    business: Boolean,
    family: Boolean,
    learning: Boolean,
    sports: Boolean,
    movies: Boolean,
    music: Boolean,
    events: Boolean,
    nightlife: Boolean,
    health: Boolean,
    beauty: Boolean,
    fashion: Boolean,
    motoring: Boolean,
    electronics: Boolean,
    groceries: Boolean,
    travel: Boolean,
    decor: Boolean
  },
  weeklyNotifcation: Number,
  weeklyNotificationSent: Number,
  created: {type: Date, default: Date.now}
});

我的回调：

app.get('/auth/facebook/callback', passport.authenticate('facebook', { failureRedirect: '/login' }), function(req, res) {
  User.findOne({uid: req.session.uid}, function(err, user) {
    if(user.email || user.location || user.phone || user.location == undefined) {
      res.redirect('/register');
    } else {
      res.redirect('/');
    }
  });
});

调用/auth/facebook后，数据将存储到mongo中。我检查数据库是否反对使用会话并检查它是否未定义，因为它不会返回字段，因为它们没有存储在数据库中。回调失败并且不返回任何数据。

任何帮助将不胜感激。

Answer 1

if(user.email === undefined || user.location === undefined || user.phone === undefined || user.location === undefined) {

可能就是你的意思。此外，您应该检查err变量以查看是否存在错误。
