可以在【Common/Controller下||模块/Controller】建一个类

类名可以是AuthController.class.php 或 CommonController.class.php（whatever）

namespace Common\Controller;
use Think\Controller;
use Think\Auth;
class AuthController extends Controller{
    public function _initialize(){
        $auth=new Auth();
        if (CONTROLLER_NAME.'/' . ACTION_NAME == "Index/index") {
            if (!$auth->check(CONTROLLER_NAME.'/' . ACTION_NAME, session('aid'))) {
                $this->error("请先登录", U("Login/login"));
            }
        } else {
            if (!$auth->check(CONTROLLER_NAME.'/' . ACTION_NAME, session('aid'))) {
                if(empty($_SESSION['aid'])) {
                    echo "<script>";
                    echo "alert('登录已过期，请重新登录!');";
                    echo "</script>";
                    exit();
                }
                echo "<script>";
                echo "alert('你没有操作权限!');";
                echo "</script>";
                echo "<h2>你没有操作权限!</h2>";
                exit();
            }
        }
    }
}

需要权限管理的类继承控制类就可以了

class IndexController extends AuthController {
