我正在使用nodeJS和expressJS服务器框架。这个问题是关于passportJS不能将超过1个用户保存到MongoDB。
首先，我设置了本地护照的电子邮件注册，并使其工作正常。其次，我设置了passport-facebook，这基本上打破了我的电子邮件注册。每个注册（电子邮件和Facebook）现在只登录一个用户，我必须继续从mongodb删除用户再次注册。当数据库中有1个用户并且我尝试注册另一个用户时 - 我收到以下错误。
process.nextTick(function() { throw err; });

我认为问题可能在于用户架构，因为每个策略都会保存不同的用户信息。因此，本地＆amp; Facebook可能无法在数据库中正确结合导致错误？如果我错了，请纠正我。
要查看的主要文件是我的userSchema（ User.js ），我的路径文件（ index.js ），其中包含我的FB策略和模块导入，和我的控制器文件（ userController.js，authController.js ），我导出我的模块和函数。

答案 0 :(得分：0)
因为我使用上述问题中提到的代码，您可以看到我实施了本地电子邮件注册以及passport-facebook身份验证。所以...导致这个令人困惑的错误的原因是以下代码是这样的：
passport.serializeUser(User.serializeUser(), function(user, done) {
done(null, user.id);
});
passport.deserializeUser(User.deserializeUser(), function(id, done) {
User.findById(id, function(err, user) {
done(err, user);
});
});
而不是简单地这样：
passport.serializeUser(User.serializeUser(), function(user, done) {
done(null, user);
});
passport.deserializeUser(User.deserializeUser(), function(user, done) {
done(null, user);
});
