Payum - 捕获时调度事件？

Question

我想知道 Payum（或 PayumBundle）是否在捕获付款时发送事件？ 目的是向客户发送确认电子邮件。

我发现什么都不是文档，我在代码源中只发现了三个事件：

• payum.gateway.pre_execute
• payum.gateway.execute
• payum.gateway.post_execute

但我猜它与付款本身无关。顺便说一句，它似乎从未与 Stripe 付款一起发送。

谢谢。

Answer 1

Payum 默认不调度任何事件。它旨在通过扩展进行扩展。例如，如果您想在实例推送通知 (Paypal IPN) 上做一些事情，您可以添加如下所述的扩展：http://payum.org/doc/1.0/Core/instant-payment-notification

还有一个扩展名为dispatch events。您必须手动创建它并添加到 payum。

我遇到了同样的问题：针对某些支付操作发送自定义事件。就我而言，我想处理 Authorize 和 Capture 动作。

我注意到Payum 请求可能会为 1 次付款操作处理多次，这就是为什么我需要将我的付款标记为已处理，以便只发送一次我的自定义事件（Payment::$customPaymentEventDispatched 的目的属性）。

这是我的付款实体：

<?php

namespace MyApp\PaymentBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Payum\Core\Model\Payment as BasePayment;

class Payment extends BasePayment
{
    // ...

    // Not persisted
    protected $payable;
    protected $customPaymentEventDispatched = false;

    // ...

    public function setPayable($payable)
    {
        $this->payable = $payable;

        return $this;
    }

    public function getPayable()
    {
        return $this->payable;
    }

    public function markAsCustomPaymentEventDispatched()
    {
        $this->customPaymentEventDispatched = true;

        return $this;
    }

    public function isCustomPaymentEventDispatched()
    {
        return $this->customPaymentEventDispatched;
    }
}

然后注册 Payum eventDispatcherExtension 和我的自定义监听器

services:        

    payum.extension.event_dispatcher:
        class: Payum\Core\Bridge\Symfony\Extension\EventDispatcherExtension
        arguments: ["@event_dispatcher"]
        tags:
            - { name: payum.extension, all: true, prepend: false }

    my_app_payment.payum.listener.payment_listener:
        class: MyApp\PaymentBundle\EventListener\PaymentListener
        arguments:
            - "@monolog.logger.payment"
        tags:
            - { name: kernel.event_listener, event: payum.gateway.post_execute }

以及监听器的代码：

<?php

namespace MyApp\PaymentBundle\EventListener;

use Payum\Core\Bridge\Symfony\Event\ExecuteEvent;
use Payum\Core\Request\Authorize;
use Payum\Core\Request\BaseGetStatus;
use Payum\Core\Request\Capture;
use Payum\Core\Model\PaymentInterface;
use Payum\Core\Request\GetHumanStatus;
use Psr\Log\LoggerInterface;
use Symfony\Component\EventDispatcher\EventDispatcherInterface;
use MyApp\PaymentBundle\Entity\Payment;
use MyApp\PaymentBundle\Event\PayablePaymentStatusChangeEvent;
use MyApp\PaymentBundle\PaymentEvents;

class PaymentListener
{
    protected $logger;

    public function __construct(LoggerInterface $logger)
    {
        $this->logger = $logger;
    }

    public function onPayumGatewayPostexecute(ExecuteEvent $event, $eventName, EventDispatcherInterface $eventDispatcher)
    {
        $request = $event->getContext()->getRequest();

        // Exclude Payum GetStatus request
        // => protect from infinite loop as following code execute one GetStatus request
        if ($request instanceof BaseGetStatus) {
            return;
        }
        // Request types requiring dispatching an event
        if (!($request instanceof Authorize || $request instanceof Capture)) {
            return;
        }

        $payment = $request->getFirstModel();
        if (!$payment instanceof PaymentInterface) {
            return;
        }

        $event->getContext()->getGateway()->execute($status = new GetHumanStatus($payment));

        if (!$payment->isCustomPaymentEventDispatched()) {
            if ($request instanceof Capture && $status->isCaptured())
            {
                $payable = $payment->getPayable();

                $this->logger->info('Dispatching PAYMENT_SUCCESS for '.$payable->__toString());

                $tmEvent = new PayablePaymentStatusChangeEvent($payment->getPayable());
                $eventDispatcher->dispatch(PaymentEvents::PAYMENT_PENDING, $tmEvent);

                $payment->markAsCustomPaymentEventDispatched();
            }
            elseif ($request instanceof Authorize && $status->isAuthorized())
            {
                $payable = $payment->getPayable();

                $this->logger->info('Dispatching PAYMENT_PENDING for '.$payable->__toString());

                $tmEvent = new PayablePaymentStatusChangeEvent($payment->getPayable());
                $eventDispatcher->dispatch(PaymentEvents::PAYMENT_PENDING, $tmEvent);

                $payment->markAsCustomPaymentEventDispatched();
            }
        }
    }
}

我对这个实现并不完全满意，但我没有找到更好的方法来实现它。如有任何反馈，我将不胜感激！

这就是您可以检查付款是否被捕获的方法：

use Payum\Core\Action\CapturePaymentAction;
use Payum\Core\Bridge\Symfony\Event\ExecuteEvent;
use Payum\Core\Request\Capture;
use Payum\Core\Request\GetHumanStatus;

class SuccessPaymentListener
{
    public function onPostExecute(ExecuteEvent $event) {
        $context = $event->getContext();
        $action = $context->getAction();
        $request = $context->getRequest();
        if ($action instanceof CapturePaymentAction && $request instanceof Capture) {
            $status = new GetHumanStatus($request->getToken());
            $gateway = $context->getGateway();
            $gateway->execute($status);
            if ($status->isCaptured()) {
                $payment = $status->getFirstModel();
                //here is your stuff
            }
        }
    }
}

services.yml：

app.payum.extension.event_dispatcher:
    class: Payum\Core\Bridge\Symfony\Extension\EventDispatcherExtension
    arguments: ["@event_dispatcher"]
    tags:
        - { name: payum.extension, all: true, prepend: false }

app.success_payment_listener:
    class: AppBundle\Listener\SuccessPaymentListener
    tags:
        - { name: kernel.event_listener, event: payum.gateway.post_execute, method: onPostExecute }
