S3 Authmate allows to generate presign URL even for object upload. However, it uses hardcoded Content-Type header in a signature.

req.Header.Set(ContentTypeHdr, "text/plain")

This header is not usable for all cases, so consider change it.

Describe the solution you'd like

As simple solution Content-Type can be dropped from signature at all, so HTTP client can set any value and get correct output.

Describe alternatives you've considered

Provide an option to configure Content-Type header value the same way as Authmate allows to configure lifetime.

Additional context

Also it would be nice to have an example of a curl command to upload file with presigned URL.
