如何使用带有 Google Drive API v3 Java 的服务帐户访问 Team Drive

Question

下午好！

我在访问 Google Team Drive 时遇到问题。

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 Drive 并在那里上传文件。 我连接到个人存储的代码：

        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

假设您已经满足先决条件，即

• 创建 Google 服务帐户
• 下载其凭据
• 与服务帐户共享团队驱动器或启用域范围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)是从共享驱动器检索文件所必需的。
