Python Auth. Header Parser

A small and simple library to parse JWT tokens embedded in Authorization or Authentication HTTP headers.
(Note: This library does not decode the JWT token. It simply extracts the JWT token string from the header string.)

Installation

pip install py-auth-header-parser

https://pypi.org/project/py-auth-header-parser/

Usage

from py_auth_header_parser import parse_auth_header

header = "Authorization: Bearer AAA, Refresh BBB"
parsed = parse_auth_header(header)

assert parsed == {
  "access_token": "AAA",
  "refresh_token": "BBB",
}

parse_auth_header() will always return a dict with two keys: access_token and refresh_token.

When a token is not present in the header or, cannot be parsed, the key's value will be None.

For example, given the following headers:

1. Authorization: Bearer AAA
2. Authorization: Bearer AAA, RefreshG1bb3r1sh

The parsed result will be:

{"access_token": "AAA", "refresh_token": None}
