如果布局是Blade模板，则可以创建一个视图编辑器，将这些变量注入到布局中.在 app/Providers/AppServiceProvider.php 中添加以下内容:

If your layout is a Blade template, you could create a view composer that injects those variables into your layout. In app/Providers/AppServiceProvider.php add something like this:

public function boot()
{
    app('view')->composer('layouts.master', function ($view) {
        $action = app('request')->route()->getAction();

        $controller = class_basename($action['controller']);

        list($controller, $action) = explode('@', $controller);

        $view->with(compact('controller', 'action'));
    });
}

然后，布局模板中将提供两个变量:$controller和$action.

You will then have two variables available in your layout template: $controller and $action.
