Missing support for UNSIGNED-PAYLOAD

[LEW21]

It's not always possible to sign the payload - especially when uploading large files to S3. That's why there exists UNSIGNED-PAYLOAD.

Unfortunately, AWSRequestsAuth.get_aws_request_headers does not support it.

Maybe delegating the signing process to aws-request-signer could help.

Can I send a fix for this ?

You can refer to the version I re-implemented based on the ideas from this repository and the official documentation. It supports UNSIGNED-PAYLOAD: https://gist.github.com/pk5ls20/3081ac14286842da31fdf187bbd5ffef
