我知道你可能会问我为什么不先用谷歌搜索解决方案，现在我可以说我已经用谷歌搜索过了，不幸的是它出现了太多的解决方案和不同的方法来做到这一点。
我的情况是这样的，我想让那些客户能够每年订阅我的服务。
从这个链接，他们提出了太多的解决方案，我不知道哪个 1 适合我的情况。当然，我想使用免费服务（直接借记需要月费）。
这意味着，我希望每年在我的客户订阅的服务到期时将交易＃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。
总之，
先谢谢了。

You could use PayPal Payments Pro with the Direct Payment API to process the initial credit card transactions. Then you can store the transaction in your system, and set your system to run a cron job and perform a reference transaction API call to charge the buyer again. This will give you the effects of setting up a recurring payment profile without actually having the service through PayPal.
However, if you prefer to do less coding and setting up your system to perform cron jobs and etc, then you could just sign up for PayPal's recurring payments/recurring billing services, which would allow you to just make an API call to PayPal to set up a profile. Then PayPal will take of billing your buyers when they should be billed.
