要在PHP中使用PayPal API处理退款,请按照以下步骤操作:
- 首先,确保已经安装了PayPal PHP SDK。如果尚未安装,可以通过Composer进行安装:
composer require paypal/rest-api-sdk-php:*
- 创建一个配置文件(例如
paypal_config.php
),并将其包含到你的项目中。在此文件中,设置PayPal API凭据和其他配置信息:
'YOUR_CLIENT_ID', 'secret' => 'YOUR_SECRET', 'settings' => [ 'mode' => 'sandbox', // 或者 'live' 'http.ConnectionTimeOut' => 30, 'log.LogEnabled' => true, 'log.FileName' => 'PayPal.log', 'log.LogLevel' => 'FINE' ] ];
- 现在,创建一个新的PHP文件(例如
refund.php
),并引入PayPal SDK和配置文件:
- 使用配置信息初始化PayPal API:
use PayPal\Rest\ApiContext; use PayPal\Auth\OAuthTokenCredential; $apiContext = new ApiContext( new OAuthTokenCredential($config['client_id'], $config['secret']) ); $apiContext->setConfig($config['settings']);
- 创建一个退款请求:
use PayPal\Api\Amount; use PayPal\Api\Refund; use PayPal\Api\RefundRequest; use PayPal\Api\Sale; $saleId = 'YOUR_SALE_ID'; // 从之前的支付中获取 $amountToRefund = new Amount(); $amountToRefund->setCurrency('USD') ->setTotal('10.00'); // 退款金额 $refundRequest = new RefundRequest(); $refundRequest->setAmount($amountToRefund); $sale = new Sale(); $sale->setId($saleId);
- 发送退款请求并处理响应:
try { $refundedSale = $sale->refund($refundRequest, $apiContext); echo "Refunded Successfully\n"; echo "Refund ID: " . $refundedSale->getId() . "\n"; echo "Refund Amount: " . $refundedSale->getAmount()->getTotal() . "\n"; } catch (Exception $ex) { echo "Error: " . $ex->getMessage() . "\n"; }
- 运行
refund.php
文件以执行退款操作。注意:请确保将
YOUR_CLIENT_ID
、YOUR_SECRET
和YOUR_SALE_ID
替换为实际的PayPal API凭据和销售ID。这样,你就可以使用PayPal PHP SDK处理退款了。根据需要调整代码以适应你的应用程序。
