Python Google Drive API 未列出文件夹中的所有文件

Question

One part of a program I am writing requires me to list the files and folders within a Google Drive folder. I am currently using the following code:

page_token = None
while True:
    response = service.files().list(pageSize=1000,q="'folder_id' in parents",fields="nextPageToken, files(id, name)").execute()
    for file in response.get('files', []):
        print('Found file: %s (%s)' % (file.get('name'), file.get('id')))
    page_token = response.get('nextPageToken', None)
    if page_token is None:
        break

For some reason, one folder that I am testing returns only one file, even if I add additional files/folders, and every other parent folder_id I try results in no files being returned. I even tried deleting the one file that is being returned, and it still gets returned when I call the function again.

If your are using service account which represent a service then:

1. enable domain wide delegation for the service account. steps are and additionalinfo here.

2. After enabling domain wide delegation ,share the desired folders which you want to list using your service/webapp with service account's email addressService account link , it would be something like "XXX...XXX.iam.gserviceaccount.com".
