I am trying to call a method from a class, but its not working
namespace Vendor\RetailOps\Service; /** * Shipment class. * */ abstract class Shipment implements \Vendor\RetailOps\Api\Shipment\ShipmentInterface { /** * @param $order */ public function createShipment(\Magento\Sales\Api\Data\OrderInterface $order) { echo'check'; exit; } use Magento\Framework\App\Bootstrap; require __DIR__ . '/../app/bootstrap.php'; $bootstrap = Bootstrap::create(BP, $_SERVER); $objectManager = $bootstrap->getObjectManager(); $state = $objectManager->get('Magento\Framework\App\State'); $state->setAreaCode('frontend'); $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); $orderid = 940; $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); $order = $objectManager->create('Magento\Sales\Api\Data\OrderInterface')->load($orderid); echo $objectManager->create('Vendor\RetailOps\Service\Shipment')->createShipment($order);
