Apple IAP收据如何在订阅系列中自动续订具有不同持续时间的订阅？

Question

我正在开发一个提供自动更新订阅的应用程序。

我不知道苹果的JSON响应如何看验证收到的哈希时，如果用户已经购买subscription.A（其中后7天更新），然后去他的iTunes设置和更改其更新为subscription.B像来自同一个订阅系列。

对于subscription.A它看起来像这样更新了几次后：

...

... 

当认购延伸到不同的时间，我认为它会当然有PRODUCT_ID subscription.B，但它有一个新的original_transaction_id，或将仍然连接到（在这种情况下）100000015494368？

由于我无法使用沙盒测试用户访问iTunes设置，因此我不知道如何测试它，并且我无法在文档中找到明确的声明。

下面是购买两个自动更新订阅的不同持续时间如何出现在收到验证回应：

{"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"} 

正如你所看到的，他们不显示为连接，共享相同的original_transaction_id和original_purchase_date。我不是100％肯定的，但我认为即使第二次订阅是在第一次订阅被取消之后购买的，也是如此。
