Question

我正在尝试使用桌面应用获取Google云端硬盘中的文件列表。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，我打印文件：

param = {}
if page_token:
    param['pageToken'] = page_token
    files = service.files().list(**param).execute()
    print files

但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？

Answer 1

如果我错了，请更正我但我相信您使用的是https://www.googleapis.com/auth/drive.file范围，该范围仅返回您的应用已使用Google Drive UI创建或已使用您的应用明确打开的文件Picker API。

要检索所有文件，您需要使用更广泛的范围：https://www.googleapis.com/auth/drive。

要了解有关不同范围的更多信息，请查看documentation。

首先，您需要遍历page_token以获取My Drive的所有内容以及任何子文件夹。还有一些其他的东西可能就像不提供查询等。试试这个：
