Using Passport.js and Express for multiple projects now, I have noticed myself doing this over and over again, namely specifying { user: req.user } explicitly for my Express routes. Ocassionally I forget to pass it, and suddenly it's like user is not even logged in anymore.
现在使用Passport.js和Express进行多个项目，我注意到自己一遍又一遍地这样做，即为Express路由明确指定{user：req.user}。偶尔我会忘记传递它，突然间用户甚至不再登录了。
How can I pass a user variable in my routes without having to explicitly write it for each route like this?
如何在我的路由中传递用户变量，而不必为此类路由显式写入？
app.get = function(req, res, next) {
res.render('home', {
title: 'Home',
user: req.user
});
};
I think everyauth has such Express helper, but does Passport.js?
我认为Everyauth有这样的Express助手，但Passport.js呢？

You could use a simple middleware for that:
你可以使用一个简单的中间件：
app.use(function(req, res, next) {
res.locals.user = req.user;
next();
});
This will make a user variable available in all templates, provided that req.user is populated. Make sure that you declare that middleware after you declare the passport.session middleware, but before any routes.
如果填充了req.user，这将使所有模板中的用户变量可用。确保在声明passport.session中间件之后但在任何路由之前声明该中间件。
