后臺控制器只有管理員登錄后才能訪問,要渲染的視圖在后臺模板目錄(`public/themes/`)里,要繼承`cmf\controller\AdminBaseController` 如: ```php <?php namespace app\demo\controller; use cmf\controller\AdminBaseController; class AdminIndexController extends AdminBaseController { public function index() { return $this->fetch(); } } ``` 上面`IndexController`要渲染的模板文件是`themes/后臺當前主題目錄/demo/admin_index/index.html` 如果后臺控制器不要登錄也可以訪問,可以通過重寫初始化方法: ```php <?php namespace app\demo\controller; use cmf\controller\AdminBaseController; class PublicController extends AdminBaseController { public function initialize() { } public function login() { return $this->fetch(':login'); } } ```
