有没有更好的方法在应用程序模块类(zend框架)中获取basepath

$basePath = dirname(__DIR__);

$basePath = $_SERVER['DOCUMENT_ROOT'];

use Zend\Stdlib\RequestInterface;
use Zend\Mvc\ApplicationInterface;

// 在应用程序模块类中获取basepath
class MyModule
{
    protected $request;
    protected $application;

    public function __construct(RequestInterface $request, ApplicationInterface $application)
    {
        $this->request = $request;
        $this->application = $application;
    }

    public function getBasePath()
    {
        $basePath = $this->request->getBasePath();
        // 或者使用 $basePath = $this->application->getRequest()->getBasePath();
        return $basePath;
    }
}
