Last active September 14, 2022 17:39
Enhanced neptunesigv4.py from https://docs.aws.amazon.com/neptune/latest/userguide/iam-auth-connecting-python.html
# Amazon Neptune version 4 signing example (version v2)
# The following script requires python 3.6+
# (sudo yum install python36 python36-virtualenv python36-pip)
# => the reason is that we're using urllib.parse() to manually encode URL
# parameters: the problem here is that SIGV4 encoding requires whitespaces
# to be encoded as %20 rather than not or using '+', as done by previous/
# default versions of the library.
