如何使用Passport.js访问Cookie集 [英] How to access Cookie set with Passport.js

问题描述

我正在使用Passport.js来实现对我的Node-App的登录.但是在我的应用程序中，我需要访问用户的ID，目前，我不知道如何实现此目的！

I'm using Passport.js to achieve login to my Node-App. But in my app, I need to get access to the user's ID and currently, I don't have an idea how to achieve this thing!

我该如何访问用户ID或自己将其发送到Cookie中?

How can I access the user-id or should I send it in a cookie myself?

推荐答案

您应该在应用中的策略配置旁边引入以下代码:

You should introduce the following code in your app, next to the configuration of the strategies:

passport.serializeUser(function(user, done) {
   done(null, user.id);
});

passport.deserializeUser(function(obj, done) {
   done(null, obj);
});

通过这种方式，当您通过身份验证的用户调用done函数时，护照负责将userId存储在cookie中. 每当您要访问userId时，都可以在请求正文中找到它. (表示为req["user"]).

In this way, when you invoke the done function with the authenticated user, passport takes care of storing the userId in a cookie. Whenever you want to access the userId you can find it in the request body. (in express req["user"]).

如果要在会话中存储其他数据，还可以开发serializeUser函数.我这样做:

You can also develop the serializeUser function if you want to store other data in the session. I do it this way:

passport.serializeUser(function(user, done) {
   done(null, {
      id: user["id"],
      userName: user["userName"],
      email: user["email"]
   });
});
