我使用passportjs构建了登录系统，它的工作原理就像魅力一样。但现在我正在努力解决如何区分管理员的登录系统。由于它在 mongoosejs 中使用不同的数据库模型架构，我不知道如何做到这一点。我在 stackoverflow 上搜索并找到了这个线程 Use multiple local strategies in PassportJS但是，我仍然无法完全理解如何将其应用到我当前的 Passport 配置中。在此代码中:
passport.serializeUser(function(user, done) {
if (isUser(user)) {
// serialize user
} else if (isSponsor(user)) {
// serialize company
}
});
isUser 和 isSponsor 函数详细是做什么的？我仍然无法得到它以及如何将它应用到我的代码中。
这是我现在的 Passport 配置。 https://github.com/pepziman/gampangpoll-node-server/blob/master/config/passport.js
目前我仍然对我的用户和管理员登录使用相同的本地登录策略，但它完全失败，因为我的用户也可以使用他们的凭据访问管理页面。我使用不同的 Mongoose 模型制定了不同的登录策略，称为管理登录，但无法理解如何更改serializeUser和deserializeUser函数来满足我的需要。任何解决方案将不胜感激。提前致谢
最佳答案
您可以按照下面的代码片段，为了有两种不同的策略(这里是学生和老师)，我们制作两个本地策略并相应地序列化和反序列化它们。希望这有帮助:)
