How do I associate an auto-renewable subscription in a way that lets me know which notifications are for which users in MY database? Is there some sort of id from the original receipt that I can store as a field for a User?
如何以允许我知道哪些用户在MY数据库中为哪些用户通知的方式关联自动续订订阅？原始收据中是否存在某种ID，我可以将其存储为用户的字段？
It is great that I know when a user cancels or renews, etc but it doesn't help that I am not sure which user this is happening for.
很高兴我知道用户何时取消或续订等，但这对我不确定发生了哪个用户没有帮助。
When you visit the docs and scroll down to Status Update Notifications, you'll notice that status notifications do have an original_transaction_id field, is this something that persists and can be relied on?
当您访问文档并向下滚动到状态更新通知时，您会注意到状态通知确实有一个original_transaction_id字段，这是否会持续存在并且可以依赖？

Yes, you can use original_transaction_id. It's property saved for all renews.
是的，您可以使用original_transaction_id。所有续订都保存了该属性。
If the user cancels their subscription and buys a new subscription, then original_transaction_id will change.
如果用户取消订阅并购买新订阅，则original_transaction_id将更改。
However, if the user upgrades or downgrades their subscription, original_transaction_id will not change.
但是，如果用户升级或降级其订阅，则original_transaction_id不会更改。
This is supported on modern versions of iOS, including iOS 10.

Another way to do it is to save an array of transaction_id values and associate these with user accounts. Depending on your needs, this might work better for you.
另一种方法是保存一系列transaction_id值并将其与用户帐户相关联。根据您的需要，这可能对您更有效。
UPD by Stafox: time-to-time original_transaction_id may changes after renew and may still the same after cancel and resubscribe.
Stafox的UPD：续订后的原始时间original_transaction_id可能会发生变化，取消和重新订阅后可能仍然相同。
