Google Drive SDK API未列出Google Drive在Google中上传的文件

我正在创建一个可以将文件插入Google云端硬盘并列出的应用程序。 我使用的是Google Drive SDK v2 API。 但我的问题是它没有列出未通过我的应用程序上传的文件。 如果我直接从Google云端硬盘上传，则不会在我的应用中列出。

以下是列出文件的方法：

private static List retrieveAllFiles(Drive service) throws IOException { List result = new ArrayList(); Files.List request = service.files().list(); do { try { FileList files = request.execute(); result.addAll(files.getItems()); request.setPageToken(files.getNextPageToken()); } catch (IOException e) { System.out.println("An error occurred: " + e); request.setPageToken(null); } } while (request.getPageToken() != null && request.getPageToken().length() > 0); return result; } 

我正在迭代这样的文件：

 List files = retrieveAllFiles(service); for(File f : files) { System.out.println("File Name : "+f.getOriginalFilename(); } 

有人可以帮我吗？ 提前致谢 …

我认为您使用的是错误的oauth范围，可能是https://www.googleapis.com/auth/drive.file ，它限制了您的应用访问由您的应用创建或打开的文件，当您应该使用https://www.googleapis.com/auth/drive可以完全控制您的应用。

我构建了我们都在寻找的function。 以下列出了google驱动器文件夹中的所有文件和文件夹。 您可以指定是否需要目录中的所有文件，或者仅指定服务在目录中拥有的文件。 只需要ID的天气，或者只需要文件名或者两者都需要的天气。
