NotImplementedError:只有tempfile.TemporaryFile可供使用

Question

我正在使用django和Google App Engine.我无法确定错误来自何处,因为如果我在本地使用它我的网站正在运行.我在GAE上部署它后工作正常,但使用googleadwords api时出现此错误:

NotImplementedError: Only tempfile.TemporaryFile is available for use

有人可以解释这个错误的含义是什么？谢谢!

编辑:我认为生成错误的代码行.

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

Answer 1

adwords库suds用于将SOAP消息发送到adwords API.suds包尝试缓存文件系统中的数据,这在App Engine标准环境中是禁止的.

Adwords包的自述文件描述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)
