Question

我正在使用django和Google App Engine。我无法确定错误的来源，因为如果我在本地网站上使用它的话就会运行。我在GAE上部署它后工作正常，但使用googleadwords api时出现错误：

NotImplementedError: Only tempfile.TemporaryFile is available for use

有人可以解释这个错误是什么意思吗？谢谢！

编辑：我认为代码行会产生错误。

 adwords_client = adwords.AdWordsClient.LoadFromStorage(os.path.dirname(os.path.abspath(__file__)) + "//googleads.yaml")

Answer 1

adwords库正在使用suds将SOAP消息发送到adwords API。 suds包尝试在文件系统中缓存数据，这在App Engine标准环境中是禁止的。

Adwords包README介绍了如何通过将虚拟缓存实现传递给adwords客户端来禁用缓存：

adwords_client = adwords.AdWordsClient(
  developer_token, oauth2_client, user_agent,
  client_customer_id=client_customer_id, cache=suds.cache.NoCache())

（您需要导入suds.cache）

NotImplementedError：只有tempfile.TemporaryFile可供使用
