在经历了很多头痛之后（就像总是使用 Google API 和服务一样），我想出了如何使用现有 API 访问 Google Play Developer API 信息（例如计费）。
1.) 在开发人员 API 控制台中创建服务帐户 (JSON) 密钥：
2.) 下载此 service-account-private-key.json 文件（不要将其与 OAuth2.0 客户端机密文件混淆！）。
3.) 在 Google Play 开发者控制台中转到 Settings -> Users & Permissions -> Invite New User 并将下载文件中的 client_email 设置为新用户的用户电子邮件。通过此视图中的复选框（例如“查看财务数据”）分配您要授予此用户的访问权限。
4.) 为您的项目添加适当的依赖项（版本 ...-1.23.0 对我不起作用）：
<dependency>
<groupId>com.google.apis</groupId>
<artifactId>google-api-services-androidpublisher</artifactId>
<version>v2-rev50-1.22.0</version>
</dependency>
5.) 将 service-account-private-key.json 文件加载到您的应用程序中。就我而言，它是一个网络服务器：
@Singleton
@Startup
public class WebserverConfiguration
{
private String serviceAccountPrivateKeyFilePath;
/** Global instance of the HTTP transport. */
public static HttpTransport HTTP_TRANSPORT;
/** Global instance of the JSON factory. */
public static JsonFactory JSON_FACTORY;
private GoogleCredential credential;
@PostConstruct
public void init()
{
assignServiceAccountFileProperty();
initGoogleCredentials();
}
public String getServiceAccountPrivateKeyFilePath()
{
return serviceAccountPrivateKeyFilePath;
}
public GoogleCredential getCredential()
{
return credential;
}
private void initGoogleCredentials()
{
try
{
newTrustedTransport();
newJsonFactory();
String serviceAccountContent = new String(Files.readAllBytes(Paths.get(getServiceAccountPrivateKeyFilePath())));
InputStream inputStream = new ByteArrayInputStream(serviceAccountContent.getBytes());
credential = GoogleCredential.fromStream(inputStream).createScoped(Collections.singleton(AndroidPublisherScopes.ANDROIDPUBLISHER));
}
catch (IOException | GeneralSecurityException e)
{
throw new InitializationException(e);
}
}
private void newJsonFactory()
{
JSON_FACTORY = JacksonFactory.getDefaultInstance();
}
private void assignServiceAccountFileProperty()
{
serviceAccountPrivateKeyFilePath = System.getProperty("service.account.file.path");
if (serviceAccountPrivateKeyFilePath == null)
{
throw new IllegalArgumentException("service.account.file.path UNKNOWN - configure it as VM startup parameter in Wildfly");
}
}
private static void newTrustedTransport() throws GeneralSecurityException, IOException
{
if (HTTP_TRANSPORT == null)
{
HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
}
}
}
6.) 现在我可以获取 Google Play Developer API 信息，例如评论：
private void invokeGoogleApi() throws IOException
{
AndroidPublisher publisher = new AndroidPublisher.Builder(WebserverConfiguration.HTTP_TRANSPORT, WebserverConfiguration.JSON_FACTORY, configuration.getCredential()).setApplicationName("The name of my app on Google Play").build();
AndroidPublisher.Reviews reviews = publisher.reviews();
ReviewsListResponse reviewsListResponse = reviews.list("the.packagename.of.my.app").execute();
logger.info("review list response = " + reviewsListResponse.toPrettyString());
}
这行得通。
我还不能测试它，但我确信获取帐单信息也可以：
private SubscriptionPurchase getPurchase() throws IOException
{
AndroidPublisher publisher = new AndroidPublisher.Builder(WebserverConfiguration.HTTP_TRANSPORT, WebserverConfiguration.JSON_FACTORY, configuration.getCredential()).setApplicationName("The name of my app on Google Play").build();
AndroidPublisher.Purchases purchases = publisher.purchases();
SubscriptionPurchase purchase = purchases.subscriptions().get("the.packagename.of.my.app", "subscriptionId", "billing token sent by the app").execute();
//do something or return
return purchase;
}
