如何为导入的模块配置日志记录？

Question

In my Superset web application, I am interested in setting the level of logging in Flask-OAuthLib to DEBUG . We can see Flask-OAuthLib access its logger here on line 26 from a Superset web application.

Superset is a web application implemented using Flask-AppBuilder . It allows for OAuth2 authentication via Flask-OAuthLib.

I want to configure Flask-OAuthLib logging from custom_sso_security_manager.py ... a module described in the Superset docs on custom OAuth configuration .

You can access the logger in exactly the same way. They are added to a global dictionary that items can be get from with getLogger(key) . So all you need is put something like this into your file after you imported the oauth lib:

oauth_logger = logging.getLogger('flask_oauthlib')
oauth_logger.setLevel(logging.DEBUG)

# it is custom for libs to have no handler (except the NullHandler)
# so you may want to add one:
oauth_logger.addHandler(logging.StreamHandler()) # just an example
