laravel 5:如何根据登录与否创建两种类型的404页面

php artisan make:middleware CheckLoggedIn

public function handle($request, Closure $next)
{
    if (auth()->check()) {
        // 已登录用户
        config(['view.paths' => [resource_path('views/logged_in')]]);
    } else {
        // 未登录用户
        config(['view.paths' => [resource_path('views/guest')]]);
    }

    return $next($request);
}

protected $routeMiddleware = [
    // ...
    'checkLoggedIn' => \App\Http\Middleware\CheckLoggedIn::class,
];

Route::group(['middleware' => 'checkLoggedIn'], function () {
    // 已登录用户的路由
    Route::get('/dashboard', function () {
        return view('dashboard');
    });
});

// 未登录用户的路由
Route::get('/home', function () {
    return view('home');
});
