【问题描述】：

我正在创建一个自定义模块，以编程方式创建订单，并使用 paypal_billing_agreement 作为付款方式。下面是我使用的订单创建代码。

<?php

namespace Vendor\Module\Model\Subscription\Order;

class Create

    public function __construct(
        \Magento\Framework\App\Helper\Context $context,
        \Magento\Store\Model\StoreManagerInterface $storeManager,
        \Magento\Catalog\Model\ProductFactory $productFactory,
        \Magento\Quote\Model\QuoteManagement $quoteManagement,
        \Magento\Customer\Model\CustomerFactory $customerFactory,
        \Magento\Customer\Api\CustomerRepositoryInterface $customerRepository,
        \Magento\Sales\Model\Service\OrderService $orderService,
        \Magento\Quote\Api\CartRepositoryInterface $cartRepositoryInterface,
        \Magento\Quote\Api\CartManagementInterface $cartManagementInterface,
        \Magento\Quote\Model\Quote\Address\Rate $shippingRate
    ) 
        $this->_storeManager = $storeManager;
        $this->_productFactory = $productFactory;
        $this->quoteManagement = $quoteManagement;
        $this->customerFactory = $customerFactory;
        $this->customerRepository = $customerRepository;
        $this->orderService = $orderService;
        $this->cartRepositoryInterface = $cartRepositoryInterface;
        $this->cartManagementInterface = $cartManagementInterface;
        $this->shippingRate = $shippingRate;
    
    /**
     * Create Order On Your Store
     *
     * @param array $orderData
     * @return int $orderId
     *
     */
    public function createOrder($orderData) 

        //init the store id and website id @todo pass from array
        $store = $this->_storeManager->getStore();
        $websiteId = $this->_storeManager->getStore()->getWebsiteId();
        //init the customer
        $customer=$this->customerFactory->create();
        $customer->setWebsiteId($websiteId);
        $customer->loadByEmail($orderData['email']);// load customet by email address
        //check the customer
        if(!$customer->getEntityId())
            //If not avilable then create this customer
            $customer->setWebsiteId($websiteId)
                ->setStore($store)
                ->setFirstname($orderData['shipping_address']['firstname'])
                ->setLastname($orderData['shipping_address']['lastname'])
                ->setEmail($orderData['email'])
                ->setPassword($orderData['email']);
            $customer->save();
        
        //init the quote
        $cart_id = $this->cartManagementInterface->createEmptyCart();
        $cart = $this->cartRepositoryInterface->get($cart_id);
        $cart->setStore($store);
        // if you have already buyer id then you can load customer directly
        $customer= $this->customerRepository->getById($customer->getEntityId());
        $cart->setCurrency();
        $cart->assignCustomer($customer); //Assign quote to customer
        //add items in quote
        foreach($orderData['items'] as $item)
            $product = $this->_productFactory->create()->load($item['product_id']);
            $cart->addProduct(
                $product,
                intval($item['qty'])
            );
        
        //Set Address to quote 
        $cart->getBillingAddress()->addData($orderData['shipping_address']);
        $cart->getShippingAddress()->addData($orderData['shipping_address']);
        // Collect Rates and Set Shipping & Payment Method
        $this->shippingRate
            ->setCode('freeshipping_freeshipping')
            ->getPrice(1);
        $shippingAddress = $cart->getShippingAddress();
        //@todo set in order data
        $shippingAddress->setCollectShippingRates(true)
            ->collectShippingRates()
            ->setShippingMethod('flatrate_flatrate'); //shipping method
        $cart->getShippingAddress()->addShippingRate($this->shippingRate);
        $cart->setPaymentMethod('paypal_billing_agreement'); //payment method
        //@todo insert a variable to affect the invetory
        $cart->setInventoryProcessed(false);
        // Set sales order payment
        $cart->getPayment()->importData(['method' => 'payapal_billing_agreement,'reference_id' => 'B-RTRHFHs8428355236']);
        // Collect total and saeve
        $cart->collectTotals();
        // Submit the quote and create the order
        $cart->save();
        $cart = $this->cartRepositoryInterface->get($cart->getId());
        $order_id = $this->cartManagementInterface->placeOrder($cart->getId());
        return $order_id;
    

当我将付款方式更改为“免费”时，它可以工作。 当我检查结帐时的实际账单协议流程时，paypal 账单协议付款方式需要额外的数据。

method: "paypal_billing_agreement", additional_data: …
additional_data:ba_agreement_id: "5"
method:"paypal_billing_agreement"

我什至想为 getpayment 方法添加相同的导入数据，但同样的问题仍然存在。 callDoReferenceTransaction() 的请求发布已正确设置所有必需的参数，但 REFERENCEID 设置为 NULL。

注意：使用为 magento 2.1 提供的 PayPal 的默认 NVP api。

抛出的异常是：

1 exception(s):
Exception #0 (Magento\Framework\Exception\LocalizedException): PayPal gateway has rejected request. ReferenceID : Mandatory parameter missing (#81253: Missing Parameter)

.

我错过了什么？

提前感谢您的帮助。

【参考方案1】：

所以我找到了解决办法，

先决条件，首先我必须从后端启用计费协议订单创建。

为此，我在观察者中进行了更改，默认情况下在 module-paypal 中将 "is_allowed" 设置为 false 到 true。

然后在代码中进行以下更改以使用参考交易创建订单，

$cart->setPaymentMethod('paypal_billing_agreement'); //payment method
$cart->setInventoryProcessed(false);
// Set sales order payment

$cart->getPayment()->setAdditionalInformation("ba_agreement_id","1");//To point the correct billing agreement in billing agreement table.

$cart->getPayment()->importData(['method' => 'paypal_billing_agreement,'reference_id' => 'B-RTRHFHs8428355236']);
// Collect total and saeve
$cart->collectTotals();
// Submit the quote and create the order
$cart->save();

当然，通过包装在 try catch 中来处理异常
