I am using requests package in Python to call some APIs. I am behind a corporate firewall, so I was using proxies to access data from the APIs. But now I need to use OAuth2 as well. Requests does not support OAuth2 by itself, we have to use requests-oauthlib for that. But requests-oauthlib does not have option to use proxies (see its documentation here).
So, how can I use both OAuth2 and proxies? Although I prefer to use requests package for its simplicity, any method is welcome.
