Issue when trying to make authenticated requests from something besides Django

[nickc92]

So I was having a devil of a time trying to get an HMAC-authenticated request from a python script using the "requests" module to work.
Peeling back the layers, what I found is that when I set the "Key", "Timestamp", and "Signature" header fields in requests.get(), when Django receives the request, the header field names are converted to "HTTP_KEY", "HTTP_TIMESTAMP", and "HTTP_SIGNATURE". This behavior is documented here:
https://docs.djangoproject.com/en/2.1/ref/request-response/#django.http.HttpRequest.META

This means that the authenticator is never finding the appropriate headers, unfortunately. Do you have any suggestions?
