How to save requests (python) cookies to a file?

Question

How to use the library requests (in python) after a request

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import requests
bot = requests.session         


        

Answer 1

I found that the other answers had problems:

• They didn't apply to sessions.
• They didn't save and load properly. Only the cookie name and value was saved, the expiry date, domain name, etc. was all lost.

This answer fixes these two issues:

import requests.cookies

def save_cookies(session, filename):
    if not os.path.isdir(os.path.dirname(filename)):
        return False
    with open(filename, 'w') as f:
        f.truncate()
        pickle.dump(session.cookies._cookies, f)


def load_cookies(session, filename):
    if not os.path.isfile(filename):
        return False

    with open(filename) as f:
        cookies = pickle.load(f)
        if cookies:
            jar = requests.cookies.RequestsCookieJar()
            jar._cookies = cookies
            session.cookies = jar
        else:
            return False

Then just call save_cookies(session, filename) to save or load_cookies(session, filename) to load. Simple as that.
