这个库旨在通过使用 symfony/event-dispatcher 库来简化Stripe WebHooks的行为。

安装

为了安装这个库，您只需使用以下命令

$ composer require pandawan-technology/stripe-web-hook

用法

为了更好地了解库的工作方式，让我们实现Stripe提供的示例，了解如何使用Webhooks 发送失败的支付电子邮件

在我们的控制器中，我们应该有类似以下的内容

        $endpointSecret = ''; // See the doc to get the correct value
        $event = new StripeFactoryEvent($request, Events::INVOICE_PAYMENT_FAILED, $endpointSignature);
        $eventDispatcher->dispatch(Events::STRIPE_WEBHOOK, $event);

        if ($exception = $event->getException()) {
            throw $exception;
        }

        return new Response();

现在，我们需要创建我们的EventSubscriber

<?php

namespace App\EventSubscriber;

use PandawanTechnology\StripeWebHook\Events;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;

// For demo purpose
use App\Repository\CustomerRepository;
use SomeMailerInterface;

class InvoicePaymentFailedEvent implements EventSubscriberInterface
{
    /**
     * @return CustomerRepository
     */
    protected $customerRepository;
    
    /**
     * @return SomeMailerInterface
     */
    protected $mailer;
    
    public function __construct(CustomerRepository $customerRepository, SomeMailerInterface $mailer) 
    {
        $this->customerRepository = $customerRepository;
        $this->mailer = $mailer;
    }

    /**
     * @inheritDoc
     */
    public static function getSubscribedEvents() 
    {
        return [
            Events::INVOICE_PAYMENT_FAILED => 'onInvoicePaymentFailed',            
        ];
    }
    
    public function onInvoicePaymentFailed(InvoicePaymentFailedEvent $event, string $eventName, EventDispatcherInterface $eventDispatcher)
    {
        if (!$customer = $this->customerRepository->find($event->getCustomerId())) {
            $event->setException(new NotFoundHttpException(sprintf('No customer with Stripe ID "%s"', $event->getCustomerId())));
            
            return; // No need to stop propagation here!
        }
        
        $this->mailer->send(
            'myapp@demo.com', // From
            [$customer->getEmail() => $customer->getName()], // To
            'Invoice payment failure', // Subject
            sprintf('Payment for %d%s failed', $event->getAmountDue(), $event->getCurrencyName())
        );
    }
}
