Token Authentication -- Manipulate Header

[npaschos]

Proposal

I am using django-rest framework along with django-prometheus in order to export metrics from my app. I have exposed an endopoint and created a Token in order to authenticate the prometheus server. The token works as expected when using Postman or curl, but the issue occurs when I try to include it in the prometheus.yaml config. The header that django-rest requires in order to authenticate with a token is of the following format:

Authorization: 'Token XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'

but the one created by Prometheus is:

Authorization: 'Bearer XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'

Note that the former has the Token keyword included, whereas the latter one the Bearer keyword.

As expected, the authentication fails. I tried changing the header but I could not find any way in the documentation, so I assume that it is not possible.

Am I missing a config parameter? If not, I propose that this change is implemented.

Note: this is my first issue/proposal, I tried following the guidelines. Let me know if anything else is required.

We only support standard authentication mechanisms, which your system is not. I'd suggest switching your authentication to use Bearer tokens.
