可以透過 iOS 驗證收據中，取得最新的訂閱資料中查看 訂閱截止日
作法：
- iOS成功購買產品後，呼叫 Fetch the Receipt Data(備註1) 去取 Apple Store 收據
- 因為 Apple Store 收據 本身有經過加密，也因為安全性的問題，需由後端去與 Apple 伺服器溝通
- 承第二點可透過 POST MAN 進行測試實際用法參考 (備註2)
- 將第一點取得的加密字串傳給後端API
- 由後端去和APPLE伺服器溝通，取得解碼後的收據詳細資料(JSONObject)
- 儲存至DB
備註：
1. iOS 原生
if let appStoreReceiptURL = Bundle.main.appStoreReceiptURL, FileManager,default.fileExists(atPath: appStoreReceiptURL.path){ do{ let receiptData = try Data(contentsOf: appStoreReceiptURL, options: .alwaysMapped) let receiptString = receiptData.base64EncodedString(options: []) // 呼叫 API } catch { print("Couldn't read receipt data with error: " + error.localizedDescription) } }
2. 驗證收據是否正確
正式驗證 API 網址
https://buy.itunes.apple.com/verifyReceipt
沙箱驗證 API 網址
https://sandbox.itunes.apple.com/verifyReceipt
資料來源：https://www.jianshu.com/p/d0ac8cec794b
3. 驗證資料的格式，必須自建為 JSONObject
https://developer.apple.com/documentation/appstorereceipts/requestbody
4.回傳的狀態碼
https://developer.apple.com/documentation/appstorereceipts/status
5. 後端
