ThinkPHP8中如何在控制器中调用另一个控制器?

<?php
....

class A extends BaseController {
	public function update(Request $request, $id) {
		$b = new \app\admin\controller\B();
		$b->update($request, $id);
	}
}

<?php
....

/**
 * 控制器基础类
 */
abstract class BaseController
{
	....

    /**
     * 构造方法
     * @access public
     * @param  App  $app  应用对象
     */
    public function __construct(App $app)
    {
        $this->app     = $app;
        $this->request = $this->app->request;

        // 控制器初始化
        $this->initialize();
    }
}

<?php
....

class A extends BaseController {
	public function update(Request $request, $id) {
		$app = new \think\App();
		$b = new app\admin\controller\B($app);
		$b->update($request, $id);
	}
}

<?php
....

class A extends BaseController {
	public function update(Request $request, $id) {
		invoke(app\admin\controller\B::class)->update($request, $id);
	}
}

 invoke(\app\index\controller\Base::class);
