❓ Why

No matter if you are currently building software using HTTP or IMAP, you should not worry about easily accessing header and associated attributes, adjectives or values.

using kiss-headers from python interpreter

I have seen so many chunks of code trying to deal with these headers; often I saw this implementation :

charset = headers['Content-Type'].split(';')[-1].split('=')[-1].replace('"', '')

No more of that ! 🤮

🔪 Features

kiss-headers is a library on steroids that allow you to handle headers with great care.

  • A backwards-compatible syntax using bracket style.
  • Capability to alter headers using simple, human-readable operator notation + and -.
  • Flexibility if headers are from IMAP4 or HTTP, use as you need with one library.
  • Ability to parse any object and extract recognized headers from it.
  • Fully type-annotated.
  • Provide great auto-completion in Python interpreter or any capable IDE.
  • 90% test coverage.

Plus all the features that you would expect from handling headers...

  • Properties syntax for headers and attribute in header.
  • Supports headers and attributes OneToOne and OneToMany.
  • Capable of parsing bytes, fp, str, dict, requests.Response and httpx._models.Response.
  • Automatically unquote value of an attribute when retrieving it.
  • Case insensitive with header name and attribute key.
  • Character - equal _ in addition of above feature.
  • Any syntax you like, we like.

✨ Installation

Whatever you like, use pipenv or pip, it simply works. Requires Python 3.6+ installed.

pip install kiss-headers

🍰 Usage

parse_it() method takes bytes, str, fp, dict or even requests.Response or httpx._models.Response itself and returns a Headers object.

from requests import get
from kiss_headers import parse_it

response = get('')
headers = parse_it(response)

headers.content_type.charset  # output: ISO-8859-1

Do not forget that headers are not OneToOne. One header can be repeated multiple times and attributes can have multiple values within the same header.

from kiss_headers import parse_it

my_cookies = """set-cookie: 1P_JAR=2020-03-16-21; expires=Wed, 15-Apr-2020 21:27:31 GMT; path=/;; Secure; SameSite=none
set-cookie: CONSENT=WP.284b10; expires=Fri, 01-Jan-2038 00:00:00 GMT; path=/;"""

headers = parse_it(my_cookies)

type(headers.set_cookie)  # output: list
headers.set_cookie[0].expires # output Wed, 15-Apr-2020 21:27:31 GMT

If this behaviour does bother you, you can lock output to always be a list. Just call lock_output_type() method.

Just a note: Accessing a header that has the same name as a reserved keyword must be done this way :

headers = parse_it('From: Ousret;\nIS: 1\nWhile: Not-True')

# this flavour
headers.from_ # to access From, just add a single underscore to it
# or..
