我對應用內購買的收據格式有疑問。
主收據對像有一個名為 的字段Subscription Expiration Date。
但是如果一個應用程序有多種類型的續訂訂閱，那麼這個字段將反映什麼？
它Subscription Expiration Date在文檔中被調用，但是如果您在下面閱讀了 json 鍵的實際名稱 is expires_date，只是想在您進行搜索之前指出這一點，但在您的應用程序中找不到它。
要回答您的問題，您將在文檔中看到，該特定鍵Subscription Expiration Date列在名為In-App Purchase Receipt Fields. 這意味著，我可以根據我自己的經驗確認，此密鑰存在於訂閱的每次應用程序內購買以及隨後的每次續訂。這意味著可以有多個購買，每個作為自己的收據 json 條目，每個都有一個expires_date.
如果您想使用該密鑰進行驗證，收據將具有從蘋果服務器發送的請求日期。使用該日期查看這些訂閱之一是否仍在運行。
希望這可以幫助。
編輯：這是一個實際解析的方向收據的例子。請注意，為了安全起見，我刪除了一些 ID。在這裡您會看到收據，在頂部您會看到收據的特定信息，然後是一次性購買，然後是續訂約 4 次的年度訂閱。
