使用Java中的客户端ID和客户端密钥连接到Google Analytics（分析）

Question

有人可以告诉我如何使用Java中的客户端ID和客户端密钥连接到Google Analytics（分析）并提取数据吗？现在，我正在使用json文件来获取数据，并且工作正常，但是在某些情况下，我需要使用客户端ID和客户端密钥从GA提取数据。以下是我如何使用json文件获取数据的代码：

private Analytics initializeAnalyticsReporting() throws GeneralSecurityException, IOException {

        httpTransport = GoogleNetHttpTransport.newTrustedTransport();
        dataStoreFactory = new FileDataStoreFactory(DATA_STORE_DIR);

        Reader clientSecretReader = new InputStreamReader(new FileInputStream(CLIENT_SECRET_JSON_RESOURCE));

        GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, clientSecretReader);

        GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(httpTransport, JSON_FACTORY,
                clientSecrets, AnalyticsScopes.all()).setDataStoreFactory(dataStoreFactory).build();

        Credential credential = new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver()).authorize("user");

        return new Analytics.Builder(httpTransport, JSON_FACTORY, credential).setApplicationName(APPLICATION_NAME)
                .build();
    }
