Passport.js - 将{user：req.user}传递给模板？ [英] Passport.js - passing {user: req.user} to template implicitly?

问题描述

现在使用Passport.js和Express为多个项目，我注意到我一遍又一遍地这样做，即为我明确指定了 {user：req.user} 快速路线。呃，我忘了通过它，突然就是用户甚至没有登录了。

如何传递一个用户 变量，而不必像这样的每个路由都明确地写出来。

  app.get = function（req，res，next）{
 res.render（'home'，{
 title：'Home'，
 user：req.user 
} ）; 
}; 
  

我认为 everyauth 有这样的Express帮手，但是是Passport.js吗？

解决方案

你可以使用简单的中间件：

  app.use（function（req，res，next）{
 res.locals。 user = req.user; 
 next（）; 
}）; 
  

这将使一个用户所有模板，只要 req.user 被填充。确保您在之后声明中间件，声明 passport.session 中间件，但在任何路由之前。

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.

How can I pass a user variable in my routes without having to explicitly write it for each route like this?

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?

解决方案

You could use a simple middleware for that:

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.
