首先，您可以创建自己的BaseController并将其扩展到其他控制器中.

First, you can probably create your own BaseController and extend it in other controllers.

第二件事是，您可以直接在View中使用Auth:user()，而无需在视图中分配任何内容.

Second thing is, that you may use Auth:user() directly in View, you don't need to assign anything in the view.

对于其他用法，您可以转到app/Providers/App/ServiceProvider.php，在boot方法中可以View::share('current_user', Auth::User());，但是当然，您首先需要添加导入名称空间:

For other usages you can go to app/Providers/App/ServiceProvider.php and in boot method you can View::share('current_user', Auth::User()); but or course you need to add importing namespaces first:

use View;
use Auth;

因为此文件位于App\Providers命名空间中

because this file is in App\Providers namespace
