Google Play商店SubscriptionPurchase.Get API响应说明

Question

我正在从Google Developers for Subscription Purchases查看此文档，请点击以下链接：

https://developers.google.com/android-publisher/api-ref/purchases/subscriptions#methods

特别是，对于字段linkedPurchaseToken，提到了两种情况：

1. 重新注册已取消但未过期的订阅
2. 从先前的订阅升级/降级

我不确定方案＃1何时发生。尝试购买，取消和还原（虽然没有失效）自动更新的订阅，但是还原后，我在响应中没有得到linkedPurchaseToken。

这是三种情况下的答复：

购买后：

{
    "kind": "androidpublisher#subscriptionPurchase",
    "startTimeMillis": "1573546099994",
    "expiryTimeMillis": "1573548136296",
    "autoRenewing": true,
    "priceCurrencyCode": "INR",
    "priceAmountMicros": "85000000",
    "countryCode": "IN",
    "developerPayload": "",
    "paymentState": 1,
    "orderId": "GPA.3359-7048-7648-05268",
    "purchaseType": 0,
    "acknowledgementState": 1
}

取消后：

{
    "kind": "androidpublisher#subscriptionPurchase",
    "startTimeMillis": "1573546099994",
    "expiryTimeMillis": "1573548016296",
    "autoRenewing": false,
    "priceCurrencyCode": "INR",
    "priceAmountMicros": "85000000",
    "countryCode": "IN",
    "developerPayload": "",
    "paymentState": 1,
    "cancelReason": 0,
    "userCancellationTimeMillis": "1573546553870",
    "cancelSurveyResult": {
        "cancelSurveyReason": 0
    },
    "orderId": "GPA.3359-7048-7648-05268",
    "purchaseType": 0,
    "acknowledgementState": 1
}

还原后：

{
    "kind": "androidpublisher#subscriptionPurchase",
    "startTimeMillis": "1573546099994",
    "expiryTimeMillis": "1573548136296",
    "autoRenewing": true,
    "priceCurrencyCode": "INR",
    "priceAmountMicros": "85000000",
    "countryCode": "IN",
    "developerPayload": "",
    "paymentState": 1,
    "orderId": "GPA.3359-7048-7648-05268",
    "purchaseType": 0,
    "acknowledgementState": 1
}

在什么情况下应该为＃1情景获得linkedPurchaseToken的线索吗？

Answer 1

Re-signup of a canceled but non-lapsed subscription：

一旦从Play商店中取消订阅->订阅，您可以通过两种方式重新订阅/重新注册-

1）从应用内重新订阅-购买令牌不同，Developer API for Subscription Purchases将在有linkedPurchaseToken的情况下给出响应。

You can allow users to resubscribe within your app by applying the same in-app product purchase flow as with a cancelled subscription by using the same product ID. 如here所述。

2）从Play商店还原-将按原样还原。在这种情况下，购买令牌是相同的，因此在这种情况下，您将不会获得任何linkedPurchaseToken。
