NotImplementedError: Only tempfile.TemporaryFile is available for use

Question

我正在使用 Django 和 Google App Engine。我无法确定错误从何而来，因为如果我在本地使用它，我的网站就可以正常运行。在我将它部署在 GAE 上后它工作正常但是当使用 googleadwords api 时出现这个错误：

NotImplementedError: Only tempfile.TemporaryFile is available for use

谁能解释一下这个错误是什么意思？谢谢！

编辑：我认为产生错误的代码行。

 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 标准环境中是被禁止的。

Adwords 包的 README 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）
