Question

我正在运行Python Eve的demo code，并且在Auth部分遇到麻烦。除了settings.py中的MongoDB URI外，我运行的代码与存储库相同。

# We want to seamlessy run our API both locally and on Heroku. If running on
# Heroku, sensible DB connection settings are stored in environment variables.
MONGO_URI = 'mongodb://****:****@localhost:27017/admin'
MONGO_DBNAME = 'apitest'

如果我在Basic Auth中放入正确的凭据（user=admin passwd=secret），一切都可以正常工作，但是如果我没有放置Authorization标头或正确的凭据，那么我不会获得401，因为我可以预期，但是应用程序崩溃并返回500。这是回溯。

我只用烧瓶就能重现问题。似乎与最新的werkzeug版本有关。 Flask没有指定要使用哪个werkzeug，只是说出高于0.14的字样，因此您会自动获得最新版本（截至今天为0.15.1）。版本0.15.0改变了http异常的实现，特别是this bit right here引入了Unauthorized http异常构造函数，因此现在不接受该response参数。在此之前，只需扩展HTTPException。

因此，我建议您在项目需求中简单固定werkzeug的特定版本。低于0.15版本的任何东西，例如0.14.1都应该适合您。
