如何在Zend Framework 1.12中集成paypal？

Question

我知道你可能会问，为什么我不先尝试谷歌解决方案，现在我可以说我已经为它搜索了，不幸的是它出现了太多的解决方案和不同的方式来做到这一点。

我的情况就是这样，我想让这些客户能够订阅我的服务每年。

从this link，他们提出了太多的解决方案，我不知道哪一个适合我的情况。当然，我想使用免费服务（直接借记需要月租费）。

这意味着，我希望每当我的客户订阅的服务过期时将交易编号存储到我的数据库中，并且它会自动向客户和我公司的电子邮件发送确认电子邮件。

综上所述，

1. 哪种方式适合我的情况。
2. 在这种情况下，cron工作是否需要？或者只需要使用paypal提供的定期付款？
3. 是否有任何链路或例如（在沙箱即编码实现）？

谢谢先进。

Answer 1

您可以使用PayPal Payments Pro和直接付款API来处理初始信用卡交易。然后，您可以将交易存储在您的系统中，并将您的系统设置为运行cron作业并执行参考交易API调用以再次向买方收费。这会给您带来的影响，即建立一个定期的付款配置文件，而无需通过PayPal实际提供服务。但是，如果您希望减少编码和设置系统以执行cron作业等，那么您只需注册PayPal的定期付款/循环计费服务，这将允许您只进行API调用到贝宝设置一个配置文件。然后，PayPal会在您的买家开具账单时对其进行结算。
