What would the new way of passport deserialization look like?
问题
我正在按照一个简单的MVC教程https://blog.logrocket.com/building-structuring-node-js-mvc-application/来构建一个登录认证系统。
直到几天前，我的代码中还有一个工作正常的序列化和反序列化部分
passport.serializeUser((user, done) => {
done(null, user.id);
});
passport.deserializeUser(async (id, done) => {
User.findById(id, (error, user) => {
done(error, user);
});
});
最近运行代码时，我开始收到错误消息Model.findById()不再接受回调。现在我明白新的方式是使用async和await来编写代码。然而，我找不到一个在线示例，指导我如何编写代码。请问我可以在这里得到帮助吗？

In am following a simple MVC tutorial https://blog.logrocket.com/building-structuring-node-js-mvc-application/ to build a login authentication system.
Till a few days back, I had a working serialize and deserialize section in my code
passport.serializeUser((user, done) => {
done(null, user.id);
});
passport.deserializeUser(async (id, done) => {
User.findById(id, (error, user) => {
done(error, user);
});
});
Recently running the code, I started getting the error Model.findById() no longer accepts a callback
Now I understand that the new way would be using write async and await. However, I couldn't find a sample online that guides me towards how to come about writing the code. Could I please be helped here?

你的问题更多涉及Mongoose而不是Passport问题，Mongoose现在使用承诺而不是回调。
要将你的代码转换，你可以使用async/await来处理承诺，但仍然需要调用passport.deserializeUser提供的回调函数：
passport.deserializeUser(async (id, done) => {
try {
return done(null, await User.findById(id));
} catch(error) {
return done(error);
}
});
英文:
Your question isn't so much a Passport question, but a Mongoose question, which now uses promises instead of callbacks.
To convert your code, you can handle the promise using async/await, but you still need to call the callback provided by passport.deserializeUser:
passport.deserializeUser(async (id, done) => {
try {
return done(null, await User.findById(id));
} catch(error) {
return done(error);
}
});
