查询 Google Drive 文件夹并更改共享权限

Question

Google Drive API 的新手，我想知道您是否可以查询 Google Drive 文件夹并批量更改共享权限。 我工作的公司一直在外部共享文件，但没有人跟踪这些文件。 一旦项目被归档，我们要确保没有任何文件仍然被共享。 我一直在检查 API 文档，但只能找到我想要实现的点点滴滴。 有人可以指出我正确的方向吗？ 我确定这一定是以前做过的......

亲切的问候！

编辑：

这是我现在拥有的代码。 根据我下面的评论，我收到一个 Gradle 错误，说使用了不推荐使用的 Gradle 功能。

Answer 1

您可以列出Drive 文件的权限，也可以遍历文件夹的文件。 然后您需要获取每一项 Permissions 以检索EmailAddress和Role 。

我假设您使用的是 Java，因此如果我们查看Quickstart ，我们可以使用它来设置脚本的凭据和令牌，而忽略其余代码。

public class DrivePerms {
private static final String APPLICATION_NAME = "Google Drive API Java Quickstart";

    private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();
    private static final String TOKENS_DIRECTORY_PATH = "tokens";

    /**
     * Global instance of the scopes required by this quickstart.
     * If modifying these scopes, delete your previously saved tokens/ folder.
     */
    private static final List<String> SCOPES = Collections.singletonList(DriveScopes.DRIVE);
    private static final String CREDENTIALS_FILE_PATH = "/credentials.json";

    /**
     * Creates an authorized Credential object.
     * @param HTTP_TRANSPORT The network HTTP Transport.
     * @return An authorized Credential object.
     * @throws IOException If the credentials.json file cannot be found.
     */
    private static Credential getCredentials(final NetHttpTransport HTTP_TRANSPORT) throws IOException {
        // Load client secrets.
        InputStream in = DrivePerms.class.getResourceAsStream(CREDENTIALS_FILE_PATH);
        if (in == null) {
            throw new FileNotFoundException("Resource not found: " + CREDENTIALS_FILE_PATH);
        }
        GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));

        // Build flow and trigger user authorization request.
        GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
                HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
                .setDataStoreFactory(new FileDataStoreFactory(new java.io.File(TOKENS_DIRECTORY_PATH)))
                .setAccessType("offline")
                .build();
        LocalServerReceiver receiver = new LocalServerReceiver.Builder().setPort(8888).build();
        return new AuthorizationCodeInstalledApp(flow, receiver).authorize("user");
    }

请注意，我省略了“导入”，您可以使用快速入门中的那些。 此外，作用域被设置为.Drive而不是.DRIVE_METADATA_READONLY。

在主类中，我声明了 HTT_TRANSPORT 和 Drive 服务（就像在快速入门中一样）：

public static void main(String... args) throws IOException, GeneralSecurityException {
    // Build a new authorized API client service.
    final NetHttpTransport HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
    Drive service = new Drive.Builder(HTTP_TRANSPORT, JSON_FACTORY, getCredentials(HTTP_TRANSPORT))
            .setApplicationName(APPLICATION_NAME)
            .build();

然后：

1. 列出文件夹的文件

     FileList result = service.files().list()
                .setFields("nextPageToken, files(id, name)")
                .setQ("'your folder Id' in parents")
                .execute();
        List<File> files = result.getFiles();

2. 获取每个文件的权限列表

 for (File file : files){

        System.out.println("File: " + file.getName());
        PermissionList result2 = service.permissions().list(file.getId())
                .execute();

        List<Permission> permsList = result2.getPermissions();

3. 获取权限列表的每个权限并打印结果：

for (Permission perms : permsList){
            Permission roles  = service.permissions().get(file.getId(), perms.getId())
                    .setFields("emailAddress, role")
                    .execute();
            System.out.println("Email: " + roles.getEmailAddress());
            System.out.println("Role: " + roles.getRole());
            System.out.println("-----------------------------------");


        }

    }
}

我希望这是有帮助的！
