将Passport的“isAuthenticated（）”暴露给视图

Question

我正在使用OAuth 2.0登录构建一个MEAN-stack webapp。我希望能够隐藏/显示视图中的内容，具体取决于用户是否登录。

在路由中执行此操作非常简单，因为我可以访问passport的“isAuthenticated（）”方法，但我无法在视图中执行此操作（隐藏/显示HTML内容，具体取决于用户是否经过身份验证）。

我希望能够做的是：

<ul>
  <li ng-show="isAuthenticated()">Profile</li>
  <li ng-hide="isAuthenticated()">Sign in</li>
</ul>

有没有办法将此功能公开给视图，以便我可以在那里使用它？还是有其他简洁的解决方案吗？

编辑：请求我的路由器

OAuth 2.0路由器

var express = require('express');
var router = express.Router();


module.exports = function(passport) {

    router.get('/bnet',
        passport.authenticate('bnet', {scope: 'wow.profile'}));

    router.get('/bnet/callback',
        passport.authenticate('bnet', {
            failureRedirect: '/' }),
        function(req, res){
            console.log('Authenticated: ' + req.isAuthenticated())
            res.redirect('https://localhost:3000/');
        });

    return router;
}

API路由器
