使用
\Magento\Sales\Api\OrderRepositoryInterface
示例：
<?php
namespace Magento\Sfshipping\Helper;
class Data extends \Magento\Framework\App\Helper\AbstractHelper
{
public function __construct(
\Magento\Framework\App\Helper\Context $context,
\Magento\Sales\Api\OrderRepositoryInterface $orderRepository
) {
$this->orderRepository = $orderRepository;
parent::__construct($context);
}
/**

*/
public function getPaymentData()
{
$orderId = 1;
$order = $this->orderRepository->get($orderId);
$payment = $order->getPayment();
$method = $payment->getMethodInstance();
echo $method->getTitle(); // Cash On Delivery
echo $method->getCode(); // cashondelivery
}
}
