CodeIgniter 4：在派生类控制器中调用父类控制器的初始化方法

<?php

        // 在这里执行需要在派生类方法执行前完成的操作
        $this->is_allowed();
    }

    {
        // 你的控制器逻辑
    }

        // 例如，检查用户是否已登录，或者是否有访问特定资源的权限
        if (!session()->get('isLoggedIn')) {
            // 如果没有权限，重定向到登录页面或显示错误信息
            return redirect()->to('/login');
        }
