Feature request: support for the HTTP Digest authentication on the requests and/or the aiohttp

Hi all!

I need to communicate with some products that have an API that support only HTTP Digest authentication, I mean, they do not support HTTP Basic authentication and it is not possible to disable the authentication.

I see that MicroPython has two HTTP client libs that can be used for that purpose:

1. requests (https://github.com/micropython/micropython-lib/tree/master/python-ecosys/requests) - It is sync, and support HTTP Basic authentication, but does not support HTTP Digest authentication
2. aiohttp (https://github.com/micropython/micropython-lib/tree/master/python-ecosys/aiohttp/aiohttp) - It is async, and does not support HTTP Basic authentication and does not support HTTP Digest authentication as well.

I see there is this uwwwauth.py -> https://github.com/pfalcon/pycopy-lib/blob/master/uwwwauth/uwwwauth.py that is a support for HTTP Digest authentication for the pycopy (It seems to be like as old fork of MicroPython). Can that help to support HTTP Digest authentication on the requests and/or aiohttp http clients?

Is it a simple or difficult task to support HTTP Digest authentication on the MicroPython requests/aiohttp? If I were to choose just one that http client libs to be supported by the HTTP Digest authentication, I would like to be the aiohttp because it is async (asyncio), so I do not need to use threads to have a non blocking code. But if is supported just on the requests lib, is very good as well.

Thank you in advance!

Inizia leggendo i percorsi client di requests e aiohttp collegati nell’issue, quindi confrontali con l’implementazione di pycopy-lib in uwwwauth.py. Decidi se il supporto deve riguardare uno o entrambi i client e considera completato il lavoro quando il client selezionato può comunicare con API che supportano solo HTTP Digest.
