권한 작업
새 Auth.php를 만들고 아래 코드를 복사한 다음 확장 새 폴더 조직에 파일을 넣고

에 넣습니다. 새 컨트롤러를 만듭니다. 확인 코드는 다음과 같습니다.
<?php namespace app\admin\controller; use \think\Controller; use think\Loader; class Base extends Controller { protected $current_action; public function _initialize() { Loader::import("org/Auth", EXTEND_PATH); $auth=new \Auth(); $this->current_action = request()->module().'/'.request()->controller().'/'.lcfirst(request()->action()); $result = $auth->check($this->current_action,session('user_id')); if($result){ echo "权限验证成功"; } } }
