如何使用服务帐户凭据将文件上传到 Google Team Drive 中的文件夹？

Question

我正在尝试使用 Google Drive Java API v3 为我们的应用程序实施一项新服务，该服务负责将文件上传到 [=120= 中的特定文件夹] 团队驱动。我使用我的公司专门为此项目创建的服务帐户，还从 Google 开发人员控制台生成了一个包含私钥的 JSON 文件。我还使用其电子邮件 xxxxx@xxxx.iam.gserviceaccount.com 将文件夹共享到服务帐户，并授予内容管理员对共享团队驱动器的权限。此外，由于某些原因，尚未向该服务帐户授予 G Suite 全域权限。

我想在这里实现什么：
我想使用服务帐户生成的私钥构建和 return 一个授权的 Google Drive 客户端服务，因此能够发送请求以将文件上传到 Google Team Drive 中的文件夹。

我目前使用的是：

IntelliJ IDEA IntelliJ IDEA 2018.1.7（旗舰版）
Spring 引导 2
Java 10.0.1

问题是什么：
我无法成功 return 授权 Google 驱动客户端服务，并且根本没有发送上传文件的请求。更令人困惑的是没有抛出异常。但是，凭据 return 使用访问令牌和到期时间成功编辑。

我已经试过了：

使用 GoogleCredential-class 到 return 凭证 （class 似乎已被弃用：https://googleapis.dev/java/google-api-client/latest/)
通过查看 Github 项目和教程
更新并检查 pom.xml
检查了共享团队云端硬盘的设置，确保它与服务帐户共享
添加日志以确保问题确实是我上面描述的问题

ContractStateUpdateService.java的相关部分：

File fileMetadata = new File();
fileMetadata.setName(fileTitle);
// setting the id of folder to which the file must be inserted to
fileMetadata.setParents(Collections.singletonList("dumbFolderId"));
fileMetadata.setMimeType("application/pdf");

byte[] pdfBytes = Base64.getDecoder().decode(base64File.getBytes(StandardCharsets.UTF_8));
InputStream inputStream = new ByteArrayInputStream(pdfBytes);

// decoding base64 to PDF and its contents to a byte array without saving the file on the file system
InputStreamContent mediaContent = new InputStreamContent("application/pdf", inputStream);

logger.info("Starting to send the request to drive api");
File file = DriveUtils.getDriveService().files().create(fileMetadata, mediaContent).execute();
logger.info("Succesfully uploaded file: " + file.getDriveId());

DriveUtils.java:

public class DriveUtils {

    private static final String APPLICATION_NAME = "Google Drive Service";

    // setting the Drive scope since it is essential to access Team Drive
    private static List<String> SCOPES = Collections.singletonList(DriveScopes.DRIVE);

    // private key is stored at the root of the project for now
    private static String PRIVATE_KEY_PATH = "/path/to/private_key.json";
    private static final Logger logger = LoggerFactory.getLogger(DriveUtils.class);

    // build and return an authorized drive client service
    public static Drive getDriveService() throws IOException, GeneralSecurityException {
        final NetHttpTransport HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
        GoogleCredentials credentials;

        try (FileInputStream inputStream = new FileInputStream(PRIVATE_KEY_PATH)){
            credentials = ServiceAccountCredentials.fromStream(inputStream).createScoped(SCOPES);
            credentials.refreshIfExpired();
            AccessToken token = credentials.getAccessToken();
            logger.info("credentials: " + token.getTokenValue());
        } catch (FileNotFoundException ex) {
            logger.error("File not found: {}", PRIVATE_KEY_PATH);
            throw new FileNotFoundException("File not found: " + ex.getMessage());
        }

        logger.info("Instantiating client next");
        // Instantiating a client: this is where the client should be built but nothing happens... no exceptions!
        Drive service = new Drive.Builder(HTTP_TRANSPORT, JSON_FACTORY, (HttpRequestInitializer) credentials)
                .setApplicationName(APPLICATION_NAME)
                .build();
        // this log should appear immediately after the client has been instantiated but still nothing happens
        logger.info("Client instantiated");

        return service;
    }

}

Answer 1

感谢您的评论，这里的建议很有帮助，值得研究。但是，我将在此处介绍的解决方案不会直接回答我的问题，即我的代码如何或为何不产生任何错误消息。所以现在，这是我解决问题的方法：

启用 Drive API. 在阅读了关于从服务帐户向 Drive API 发出请求的大部分文章和文档后，很明显如果我们没有从 Google API 控制台启用驱动器 API，我的代码将无法工作。
正在将三个依赖的版本降级到1.23.0.

pom.xml:

 <dependency>
    <groupId>com.google.api-client</groupId>
    <artifactId>google-api-client</artifactId>
    <version>1.23.0</version>
 </dependency>
 <dependency>
    <groupId>com.google.apis</groupId>
    <artifactId>google-api-services-drive</artifactId>
    <version>v3-rev110-1.23.0</version>
 </dependency>
 <dependency>
    <groupId>com.google.oauth-client</groupId>
    <artifactId>google-oauth-client-jetty</artifactId>
    <version>1.23.0</version>
 </dependency>

将属性 setSupportsTeamDrive 的值设置为 true。 如果没有属性我们将无法将文件保存到Team Drive 中的共享文件夹。

ContractStateUpdateService.java:

File fileMetadata = new File();
fileMetadata.setName(fileTitle);

// setting the id of folder to which the file must be inserted to
fileMetadata.setParents(Collections.singletonList("dumbTeamDriveId"));
fileMetadata.setMimeType("application/pdf");

// decoding base64 to PDF and its contents to a byte array without saving the file on the file system
byte[] pdfBytes = Base64.getDecoder().decode(base64File.getBytes(StandardCharsets.UTF_8);
InputStream inputStream = new ByteArrayInputStream(pdfBytes);
InputStreamContent mediaContent = new InputStreamContent("application/pdf", inputStream);

try {
  // upload updated agreement as a PDF file to the Team Drive folder
  DriveUtils.getDriveService().files().create(fileMetadata, mediaContent)
                            .setSupportsTeamDrives(true) // remember to set this property to true!
                            .execute();
} catch (IOException ex) {
  logger.error("Exception: {}", ex.getMessage());
  throw new IOException("Exception: " + ex.getMessage());
} catch (GeneralSecurityException ex) {
  logger.error("Exception: {}", ex.getMessage());
  throw new GeneralSecurityException("Exception: " + ex.getMessage());
}

方法拆分，逻辑更清晰

来自 DriveUtils-class 的更新代码：

// create and return credential
private static Credential getCredentials() throws IOException {
    GoogleCredential credential = GoogleCredential.fromStream(new FileInputStream(PRIVATE_KEY_PATH))
                .createScoped(SCOPES);

    return credential;
}

// build and return an authorized drive client service
public static Drive getDriveService() throws IOException, GeneralSecurityException {
    final NetHttpTransport HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();

    // Instantiating a client
    Drive service = new Drive.Builder(HTTP_TRANSPORT, JSON_FACTORY, getCredentials())
                .setApplicationName(APPLICATION_NAME)
                .build();

    return service;
}
