我正在运行Python Eve的demo code，我遇到了Auth部分的麻烦。我正在运行的代码与repo相同，但settings.py中的MongoDB URI除外。
# 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（这是user=admin passwd=secret）中放置正确的凭据，但是如果我没有放置Authorization标头或正确的凭据我没有得到401，正如我所料，但应用程序崩溃返回500，一切正常。是追溯。

我只用瓶子重现了这个问题。看起来它与最新的werkzeug版本有关。 Flask没有指定使用哪个werkzeug，只是说出0.14以上的任何内容，因此您自动获得最新版本（截至今天为0.15.1）。版本0.15.0稍微改变了http异常的实现，特别是this bit right here引入了Unauthorized http异常构造函数，因此它现在不接受response参数。之前它只是扩展HTTPException。
因此，我建议您在项目要求中固定特定版本的werkzeug。任何低于0.15的版本，比如说0.14.1应该适合你。
