不使用PyDrive元数据更改文件权限

Question

我希望有人能帮忙。我正在使用PyDrive进行身份验证，并将一个文件上传到我的Google Drive，没有任何问题。然后，我尝试通过更新其元数据来更改同一文件的权限以允许共享。

drive = GoogleDrive(gauth)

file1 = drive.CreateFile({'title': fName, 'shareable':True, 
        'userPermission': [{'kind':'drive#permission', 'type': 'anyone',
        'value': 'anyone','role': 'reader'}]})
file1.SetContentFile(fName)

但是，当我打印userPermission时，它似乎没有按照我的预期设置权限。

userPermission = file1['userPermission']
pprint.pprint(userPermission)

我得到：

{u'etag': u'"pvTNHKA6KkAgXTpZXMwU4Pa7ELo/gZDvZYCYVjI-u0hbut2HQwdCArU"',
 u'id': u'me',
 u'kind': u'drive#permission',
 u'role': u'owner',
 u'selfLink': u'https://www.googleapis.com/drive/v2/files/0B1aI5mMxQzh3MktDMWl1ZFdOZw0/permissions/me',
 u'type': u'user'
}

我不知道为什么权限设置正确。我没有任何错误。我在userPermission中设置变量的方式有什么问题吗？谢谢你的帮助。

我不确定您是否可以在文件创建期间设置权限。另外，我不确定您是否可以修改userPermission。但您可以使用InsertPermission修改权限列表。

下面是如何添加共享权限的示例。我认为下面的代码是不言自明的。

from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive

def get_drive_handle():
    gauth = GoogleAuth()
    gauth.LocalWebserverAuth()
    drive = GoogleDrive(gauth)
    return drive

def main():
    drive = get_drive_handle()

    # create an example file
    file = drive.CreateFile({
        'title':    'example.txt'
       ,'mimeType': 'text/plain'
    })
    file.Upload()

    # original permissions
    file.FetchMetadata(fields='permissions')
    print('-' * 10);
    print(file['permissions'])

    # insert new permission
    permission = file.InsertPermission({
        'type':  'anyone'
       ,'value': 'anyone'
       ,'role':  'reader'
    })

    # new permission created above
    print('-' * 10);
    print(permission)

    # all permissions
    file.FetchMetadata(fields='permissions')
    print('-' * 10);
    print(file['permissions'])    

if __name__ == '__main__':
    main()
