从 GoogleCredential 迁移到 GoogleCredentials

Question

目前，我正在使用以下实现，但代码显示 GoogleCredential 已弃用。

GoogleCredential credential = new GoogleCredential.Builder()
                    .setClientSecrets(clientId, clientSecret)
                    .setTransport(HTTP_TRANSPORT)
                    .setJsonFactory(JSON_FACTORY)
                    .build();
            credential.setRefreshToken(refreshToken);

我检查并应该使用 GoogleCredentials 或其他 google-auth-library 类。但是，它们似乎都需要服务帐户。 GoogleCredential 在没有服务帐户的情况下为我工作。只需要创建 oauth 凭据。我还生成了刷新令牌，但不确定如何将它们与新库一起使用。我应该在这里使用什么？目标是只允许单个用户（我们的后端代码）访问 google api。

我没有看到任何其他关于 java 的问题实际上得到了回答。

编辑-根据评论更新发布我的整个设置-

public Credentials getCredentials() throws GeneralSecurityException, IOException {

        final NetHttpTransport HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
        final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();

        try(InputStream in = getCredentialsAsInputStream()) {

            if (in == null) {
                throw new FileNotFoundException("Resource not found: " + CREDENTIALS_FILE_PATH);
            }
            GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));

            String clientId = clientSecrets.getDetails().getClientId();
            String clientSecret = clientSecrets.getDetails().getClientSecret();

            Credentials credential = UserCredentials.newBuilder()
                    .setClientId(clientId)
                    .setClientSecret(clientSecret)
                    .setRefreshToken(refreshToken)
                    .build();

            return credential;

并用于设置驱动器

public Drive getDriveService() {
        try {
            Credentials credential = getCredentials();
            HttpRequestInitializer httpRequestInitializer = new HttpCredentialsAdapter(credential);
            final NetHttpTransport HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
            return new Drive.Builder(HTTP_TRANSPORT, JSON_FACTORY, httpRequestInitializer)
                    .setApplicationName(DRIVE_API_APPLICATION_NAME)
                    .setHttpRequestInitializer(httpRequest -> {

                        httpRequestInitializer.initialize(httpRequest);
                        httpRequest.setConnectTimeout(2 * 60000);  // 2 minutes connect timeout
                        httpRequest.setReadTimeout(2 * 60000);  // 2 minutes read timeout

                    })
                    .build();
        } catch (GeneralSecurityException | IOException e){
            log.error("Error creating drive service class : {}", e);
        }
        return null;
    }

尝试使用google-auth-library，因为它定义了类GoogleCredentials：

Google Credentials = new GoogleCredentials.Builder()
            .setClientSecrets(clientId, clientSecret)
            .setTransport(HTTP_TRANSPORT)
            .setJsonFactory(JSON_FACTORY)
            .build();
            credential.setRefreshToken(refreshToken);

您也可以查看GoogleCredentials 的 Java 文档

看来您正在尝试使用Drive API，因此您不妨检查此thread 关于连接到驱动器服务的信息。
