Yii2 贝宝支付集成

Question

我正在使用 https://www.yiiframework.com/extension/bitcko/yii2-bitcko-paypal-api#usage 和 yii2 来启用付款，我的代码如下所示。

public function actionMakePayment(){
          if(!Yii::$app->user->getIsGuest()){
               // Setup order information array
              $params = [
                  'order'=>[
                      'description'=>'Payment description',
                      'subtotal'=>45,
                      'shippingCost'=>0,
                      'total'=>45,
                      'currency'=>'USD',
                  ]
              ];
            // In case of payment success this will return the payment object that contains all information about the order
            // In case of failure it will return Null

            Yii::$app->PayPalRestApi->processPayment($params);
        }else{
          Yii::$app->response->redirect(Url::to(['site/signup'], true));
        }

一切都按照我的预期进行，这个调用将这样的东西返回给 dom。

如何将其存储到我的数据库中？对于特定的用户 ID，我可以使用此获取用户 ID。

echo Yii::$app->user->id;

我想将此值与用户 ID 一起存储，我该怎么做？并向用户发送付款成功消息:)

Answer 1

Paypal PHP-SDK 为您提供setCustom()添加自定义字段值，您可以使用它发送用户id，然后在执行支付后在交易对象中检索它。

您使用的只是使用 Paypal SDK 功能的自定义组件，您应该扩展类 bitcko\paypalrestapi\PayPalRestApi.php 以覆盖函数 checkOut() 并将 ->setCustom(Yii::$app->user->id) 添加到此 line 中的链中，因为它不提供任何设置自定义字段的方法，因此只需将该方法的整个代码复制到您的新类中并添加上述内容。

您的课程应如下所示。

注意：将文件添加到 common/components 文件夹中。

<?php
namespace common\components;

use bitcko\paypalrestapi\PayPalRestApi as PayPalBase;
use PayPal\Api\Amount;
use PayPal\Api\Details;
use PayPal\Api\Item;
use PayPal\Api\ItemList;
use PayPal\Api\Payer;
use PayPal\Api\Payment;
use PayPal\Api\RedirectUrls;
use PayPal\Api\Transaction;
use PayPal\Exception\PayPalConnectionException;
use yii\helpers\Url;
use Yii;

class PaypalRestApi extends PayPalBase
{

    public function checkOut($params)
    {
        $payer = new Payer();
        $payer->setPaymentMethod($params['method']);
        $orderList = [];

        foreach ($params['order']['items'] as $orderItem) {
            $item = new Item();
            $item->setName($orderItem['name'])
                ->setCurrency($orderItem['currency'])
                ->setQuantity($orderItem['quantity'])
                ->setPrice($orderItem['price']);
            $orderList[] = $item;
        }
        $itemList = new ItemList();
        $itemList->setItems($orderList);
        $details = new Details();
        $details->setShipping($params['order']['shippingCost'])
            ->setSubtotal($params['order']['subtotal']);
        $amount = new Amount();
        $amount->setCurrency($params['order']['currency'])
            ->setTotal($params['order']['total'])
            ->setDetails($details);
        $transaction = new Transaction();
        $transaction->setAmount($amount)
            ->setItemList($itemList)
            ->setDescription($params['order']['description'])
            ->setCustom(Yii::$app->user->id)
            ->setInvoiceNumber(uniqid());

        $redirectUrl = Url::to([$this->redirectUrl], true);
        $redirectUrls = new RedirectUrls();
        $redirectUrls->setReturnUrl("$redirectUrl?success=true")
            ->setCancelUrl("$redirectUrl?success=false");
        $payment = new Payment();
        $payment->setIntent($params['intent'])
            ->setPayer($payer)
            ->setRedirectUrls($redirectUrls)
            ->setTransactions(array($transaction));
        try {
            $payment->create($this->apiContext);
            return \Yii::$app->controller->redirect($payment->getApprovalLink());
        } catch (PayPalConnectionException $ex) {
            // This will print the detailed information on the exception.
            //REALLY HELPFUL FOR DEBUGGING
            \Yii::$app->response->format = \yii\web\Response::FORMAT_HTML;
            \Yii::$app->response->data = $ex->getData();
        }
    }
}

现在将common/config/main.php 或frontend/config/main.php 中的PayPalRestApi 组件类的配置更改为您创建的新类

'components'=> [
    ...
 'PayPalRestApi'=>[
      'class'=>'common\components\PayPalRestApi',
  ]
    ...
]

所以现在您可以使用

获得相同的用户 ID

$response = \yii\helpers\Json::decode( Yii::$app->PayPalRestApi->processPayment($params));
$user_id = $response['transactions'][0]['custom'];
