我正在為管理員創建自定義防護，但收到錯誤“未定義身份驗證防護”我嘗試過“php artisan config：clear 和 php artisan config 緩存”，但仍然是錯誤。我想知道我做錯了什么。這是我的身份驗證配置    <?phpreturn [    /*    |--------------------------------------------------------------------------    | Authentication Defaults    |--------------------------------------------------------------------------    |    | This option controls the default authentication "guard" and password    | reset options for your application. You may change these defaults    | as required, but they're a perfect start for most applications.    |    */    'defaults' => [        'guard' => 'web',        'passwords' => 'users',    ],        /*    |--------------------------------------------------------------------------    | Authentication Guards    |--------------------------------------------------------------------------    |  | Next, you may define every authentication guard for your application.    | Of course, a great default configuration has been defined for you    | here which uses session storage and the Eloquent user provider.    |    | All authentication drivers have a user provider.
