是否有可能知道订阅是作为免费试用购买的? 目前我无法找到如何在服务器/设备端执行此操作的方法。
有人有建议怎么做吗?

2017年6月9日,在页面https://developers.google.com/android-publisher/api-ref/purchases/subscriptions上显示了有关paymentState
- 2
新值的信息,这意味着"免费试用"。

花了几天后,我将分享我的解决方案(在客户端)。
首先,您需要允许Google Play开发者控制台中的API访问权限并创建service account
(docs)。
您将获得类似于以下的帐户ID:your-service@api-621**********846-16504.iam.gserviceaccount.com
重要:在Google开发者帐户的“用户和权限”部分中添加“查看财务数据”权限。
还要下载p12密钥并将其放在资产文件夹中。
获取订阅详细信息的代码(您需要知道订阅令牌)
HttpTransport httpTransport = new NetHttpTransport();
JsonFactory jsonFactory = new JacksonFactory();
List<String> scopes = new ArrayList<String>();
scopes.add(AndroidPublisherScopes.ANDROIDPUBLISHER);
HttpRequestInitializer credential = null;
try {
KeyStore keystore = KeyStore.getInstance("PKCS12");
keystore.load(context.getAssets().open("key.p12"), "notasecret".toCharArray());
PrivateKey pk = (PrivateKey) keystore.getKey("privatekey", "notasecret".toCharArray());
credential = new GoogleCredential.Builder().setJsonFactory(jsonFactory)
.setTransport(httpTransport)
.setServiceAccountId("your-service@api-621**********846-16504.iam.gserviceaccount.com")
.setServiceAccountPrivateKey(pk)
.setServiceAccountScopes(scopes)
.build();
} catch (GeneralSecurityException e) {
} catch (IOException e) {
}
AndroidPublisher publisher = new AndroidPublisher.Builder(httpTransport, jsonFactory, credential).build();
AndroidPublisher.Purchases purchases = publisher.purchases();
try {
AndroidPublisher.Purchases.Subscriptions.Get get = purchases.subscriptions()
.get(context.getPackageName(), Constants.SUBSCRIPTION_ID, subscription_token);
final SubscriptionPurchase purchase = get.execute();
if (purchase != null && purchase.getPaymentState() != null) {
int paymentState = purchase.getPaymentState();
if (paymentState == 0) {
// Subscriber with payment pending
} else if (paymentState == 1) {
// Subscriber in good standing (paid)
} else if (paymentState == 2) {
// Subscriber in free trial
}
}
} catch (IOException e) { }
get.execute()是网络请求,因此您需要在单独的线程上运行此代码(我使用过RxJava)
您需要使用AndroidPublisher和Play Services身份验证库
implementation 'com.google.apis:google-api-services-androidpublisher:v3-rev22-1.25.0'
implementation 'com.google.android.gms:play-services-auth:15.0.1'
