我正在尝试使用桌面应用程序获取我的 Google Drive 中的文件列表。代码如下:
def main(argv):
    storage = Storage('drive.dat')
    credentials = storage.get()
    if credentials is None or credentials.invalid:
        credentials = run(FLOW, storage)
    # Create an httplib2.Http object to handle our HTTP requests and authorize it
    # with our good Credentials.
    http = httplib2.Http()
    http = credentials.authorize(http)
    service = build("drive", "v2", http=http)
    retrieve_all_files(service)
然后在retrieve_all_files 中打印文件:
param = {}
if page_token:
    param['pageToken'] = page_token
    files = service.files().list(**param).execute()
    print files
但是在我对我的帐户进行身份验证后,打印的文件列表中没有任何项目。有没有人有类似的问题或知道解决方案?
