How to access Cookie set with Passport.js
提问by Lukas Olsen
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!
我正在使用 Passport.js 来登录我的 Node-App。但是在我的应用程序中，我需要访问用户的 ID，目前，我不知道如何实现这一目标！
How can I access the user-id or should I send it in a cookie myself?
我如何访问用户 ID 或者我应该自己在 cookie 中发送它？

You should introduce the following code in your app, next to the configuration of the strategies:
您应该在您的应用程序中，在策略配置旁边引入以下代码：
passport.serializeUser(function(user, done) {
done(null, user.id);
});
passport.deserializeUser(function(obj, done) {
done(null, obj);
});
In this way, when you invoke the donefunction 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"]).
这样，当您done使用经过身份验证的用户调用该函数时，passport 负责将 userId 存储在 cookie 中。每当您想访问 userId 时，您都可以在请求正文中找到它。（在快递 req["user"]）。
You can also develop the serializeUserfunction if you want to store other data in the session. I do it this way:
serializeUser如果您想在会话中存储其他数据，您也可以开发该功能。我这样做：
passport.serializeUser(function(user, done) {
done(null, {
id: user["id"],
userName: user["userName"],
email: user["email"]
});
});

Add to signin path
添加到登录路径
res.cookie('userid', user.id, { maxAge: 2592000000 }); // Expires in one month
Add to signout path
添加到注销路径
res.clearCookie('userid');

If you're using the angular-fullstackgenerator, this is how I modified setUserCookieto get the _idin the user cookie (which I later can retrieve in AngularJS).
如果您使用的是angular-fullstack生成器，这就是我修改setUserCookie以获取_id用户 cookie（稍后我可以在 AngularJS 中检索）中的方式。
setUserCookie: function(req, res, next) {
if (req.user) {
req.user.userInfo['_id'] = req.user._id;
console.log('Cookie', req.user.userInfo);
// Splice in _id in cookie
var userObjWithID = {
"provider": req.user.userInfo.provider,
"role": req.user.userInfo.role,
"name": req.user.userInfo.name,
"_id": req.user._id
};
res.cookie('user', JSON.stringify(userObjWithID));
}
next();
}

Alternatively you could do the following:
或者，您可以执行以下操作：
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());
app.use((req, res, next) => {
res.locals.login = req.isAuthenticated();
res.locals.thisUser = req.user;
next();
});
