我正在我的应用程序中实现 Google 的应用内结算库，并且想知道处理以下情况的最佳方法

1. 多设备和单用户

Use Case:

• User U1 with Google Play Store Account G1 subscribes to Subscription S1.
• Now User U1 log out from the app and User U2 login the app.

Queries:

• What will happen if User U2 tries to subscribe the Subscription S1?
• Shall we restrict the User U2 by saying "This Subscription has already been subscribed to some other user from this Google Account"?

1. 单个设备和多个用户

Use Case I:

• User U1 with Google Play Store Account G1 subscribes to Subscription S1.
• User U1 with Google Play Store Account G2 tries to subscribe Subscription S1.

Queries:

• Shall we restrict the User U1 by saying "You have already subscribed to this subscription by some other Google Account"?

Use Case II

• User U1 with Google Play Store Account G1 subscribes to Subscription S1.
• User U1 with Google Play Store Account G2 tries to subscribe Subscription S2.

Queries:

• Shall we allow the user to subscribe to different subscriptions with different Google Account?

一般查询:

• Shall we map each user with a different Google Account and if the user tries to purchase with some other Google Account, restrict it OR ask him to delink his existing linked Google Account first?
• Can we subscribe(purchase) a subscription from 2 users using the same Google Play Account? (Say using different accountId https://developer.android.com/reference/com/android/billingclient/api/BillingFlowParams.Builder#setobfuscatedaccountid)

我期待在最佳实践和事实方面对我的查询做出回应。

最佳答案

应用内商品的购买和订阅都与进行购买时使用的 Google 帐户严格关联。

您无法从一个 Google 帐户知道另一个帐户进行的购买，如果可能的话，这将是一个严重的安全问题。

如果两个用户(两个谷歌账户)想要使用同一个订阅，他们都必须单独购买。
