如何通过 Google Drive API v3 Java 使用服务帐户访问 Team Drive

Question

下午好！

我无法访问 Google Team Drive。

我需要创建文件夹并从本地存储上传文件，所有这些都应该由我的应用程序完成。

目前，我已经学会了连接到我的个人 Google 云端硬盘并在那里上传文件。我的个人存储连接代码：

        Drive service = new Drive.Builder(HTTP_TRANSPORT, JSON_FACTORY, credential) //
                .setApplicationName(APPLICATION_NAME).build();


        // Print the names and IDs for up to 10 files.
        FileList result = service.files().list().setPageSize(10).setFields("nextPageToken, files(id, name)").execute();
        List<File> files = result.getFiles();
        if (files == null || files.isEmpty()) {
            System.out.println("No files found.");
        } else {
            System.out.println("Files:");
            for (File file : files) {
                System.out.printf("%s (%s)\n", file.getName(), file.getId());
            }
        }

告诉我，如何在 Java 中连接到 Google Team Drive 并在那里上传文件？ 谢谢：）

使用 java 中的服务帐户连接到团队驱动器

假设您已经满足了先决条件，即

• 创建 Google 服务帐户
• 下载其凭据
• 要么与服务帐户共享团队驱动器，要么启用域范围的委派以模拟有权访问团队驱动器的用户

您的代码应如下所示：

   private static final String APPLICATION_NAME = "YOUR APPLICATION";
   private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();

   private static final List < String > SCOPES = Collections.singletonList("XXXINSERTHEREYOURSCOPEXXXX");

   public static void main(String...args) throws IOException, GeneralSecurityException {
    final NetHttpTransport HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();

    File pk12 = new File("quickstartserv.p12");
    String serviceAccount = "EMAIL FO YOUR SERVICE ACCOUNT.iam.gserviceaccount.com";

    // Build service account credential.Builder necessary for the ability to refresh tokens

    GoogleCredential getCredentials = new GoogleCredential.Builder()
     .setTransport(HTTP_TRANSPORT)
     .setJsonFactory(JSON_FACTORY)
     .setServiceAccountId(serviceAccount)
     .setServiceAccountPrivateKeyFromP12File(pk12)
     .setServiceAccountScopes(SCOPES)
     .setServiceAccountUser("xxx") //IF YOU WANT TO IMPERSONATE A USER
     .build();

    // Build a new authorized API client service.

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

     FileList result = service.files().list().setPageSize(10).setQ('"ID OF THE SHARED DRIVE" in parents').setIncludeTeamDriveItems(true).setSupportsTeamDrives(true).setFields("nextPageToken, files(id, name)").execute();
     ...
   }

请注意，setIncludeTeamDriveItems(true) 和 setSupportsTeamDrives(true) 是从共享驱动器中检索文件所必需的。
