Google Drive SDK API没有列出java中Google Drive上传的文

Google Drive SDK API does not lists the file uploaded by Google Drive in java(Google Drive SDK API没有列出java中Google Drive上传的文件)

问题描述

我正在创建一个可以将文件插入 Google Drive 并列出它的应用程序.我正在使用 Google Drive SDK v2 API.但我的问题是它没有列出不是通过我的应用程序上传的文件.如果我直接从 Google 驱动器上传，它不会在我的应用程序中列出.

I am creating an application which can insert files into Google Drive and lists it. I am using Google Drive SDK v2 API. But my problem is it is not listing files which is not uploaded through my application. If I upload directly from Google drive it is not listed in my application.

列出文件的方法如下:

private static List<File> retrieveAllFiles(Drive service) throws IOException {
        List<File> result = new ArrayList<File>();
        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:

and I am iterating files like this :

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

谁能帮帮我?在此先感谢...

Can anyone help me please ? Thanks in advance ...

推荐答案

我认为你使用了错误的 oauth 范围，可能是 https://www.googleapis.com/auth/drive.file当您应该使用 https://www.googleapis.com/auth/drive 来完全控制您的应用时，这会限制您的应用访问您的应用创建或打开的文件.

I think you are using the wrong oauth scope, probably https://www.googleapis.com/auth/drive.file which restrict your app's access to file created or opened by your app, when you should use https://www.googleapis.com/auth/drive which gives full control to your app.
