magento2:如何使用magento 2中的对象管理器从前端删除产品？

$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 
$product = $objectManager->create('Magento\Catalog\Model\Product');
$product->load($productID)->delete();

//get product id
$productID = 10;
$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 
$product = $objectManager->get('Magento\Framework\Registry');
//set isSecureArea code here
$product->registry('isSecureArea',true);
$product->delete();
