ios - 对于订阅系列中具有不同持续时间的自动续订订阅，Apple IAP 收据看起来如何？

Question

我正在开发一款提供自动续订订阅的应用。

如果用户购买了 subscription.A(7 天后续订)，然后转到他的 iTunes，我不知道在验证收据哈希时来自 Apple 的 JSON 响应会是什么样子设置并将其更改为从同一订阅系列续订到 subscription.B。

对于subscription.A，在续订几次后会是这样的:

...

当订阅延长到不同的持续时间时，我认为它当然会有 product_id subscription.B，但它会不会有一个新的 original_transaction_id，或者仍然连接到(在这种情况下)100000015494368？

由于我无法通过沙盒测试用户访问 iTunes 设置，我不知道如何测试它，而且我在文档中找不到明确的说明。

下面是收据验证响应中出现的两次不同持续时间的自动续订订阅购买:

{"quantity":"1", "product_id":"subscription.A", "transaction_id":"1000000276920213", "original_transaction_id":"1000000276916420", "purchase_date":"2017-02-25 14:34:05 Etc/GMT", "purchase_date_ms":"1488033245000", "purchase_date_pst":"2017-02-25 06:34:05 America/Los_Angeles", "original_purchase_date":"2017-02-25 13:03:10 Etc/GMT", "original_purchase_date_ms":"1488027790000", "original_purchase_date_pst":"2017-02-25 05:03:10 America/Los_Angeles", "expires_date":"2017-02-25 14:39:05 Etc/GMT", "expires_date_ms":"1488033545000", "expires_date_pst":"2017-02-25 06:39:05 America/Los_Angeles", "web_order_line_item_id":"1000000034442002", "is_trial_period":"false"}, 
{"quantity":"1", "product_id":"subscription.B", "transaction_id":"1000000276964864", "original_transaction_id":"1000000276916420", "purchase_date":"2017-02-26 09:05:14 Etc/GMT", "purchase_date_ms":"1488099914000", "purchase_date_pst":"2017-02-26 01:05:14 America/Los_Angeles", "original_purchase_date":"2017-02-25 13:03:10 Etc/GMT", "original_purchase_date_ms":"1488027790000", "original_purchase_date_pst":"2017-02-25 05:03:10 America/Los_Angeles", "expires_date":"2017-02-26 09:08:14 Etc/GMT", "expires_date_ms":"1488100094000", "expires_date_pst":"2017-02-26 01:08:14 America/Los_Angeles", "web_order_line_item_id":"1000000034442107", "is_trial_period":"false"}

如您所见，它们确实显示为已连接，共享相同的 original_transaction_id 和 original_purchase_date。我不是 100% 确定，但我认为即使在取消第一个订阅后购买第二个订阅也是如此。
