How to store cookies received from a request?

I have an application where I make a request like this:

headers = {'Content-Type': 'application/json;charset=ISO-8859-1'}
d = {'db_name': 'a_database', 'username': 'me', 'password': 'apw'}

db_url = "http://123.45.67.89:1234/something/rest/connections"
r = requests.post(db_url, data=json.dumps(d), headers=headers)

This will then create a cookie:

r.cookies
<RequestsCookieJar[Cookie(version=0, name='removed', value='removed', port=None, port_specified=False, domain='123.45.67.89', domain_specified=False, domain_initial_dot=False, path='/something', path_specified=True, secure=False, expires=None, discard=True, comment=None, comment_url=None, rest={}, rfc2109=False), Cookie(version=0, name='connectname', value='alsoremoved', port=None, port_specified=False, domain='123.45.67.89', domain_specified=False, domain_initial_dot=False, path='/something/rest', path_specified=False, secure=False, expires=None, discard=True, comment=None, comment_url=None, rest={'HttpOnly': None}, rfc2109=False)]>

I can then use r.cookies to make additional requests where I then specify cookies=r.cookies.

In my flask application, I would like to use the cookie in several functions, so I thought I would store it in session:

from flask import Flask, render_template, request, jsonify, session

session['cookies'] = r.cookies

so that I can then later use

r2 = requests.post(someurl, data=json.dumps(anotherd), headers=headers, cookies=session['cookies'])

However, that results in

Object of type 'RequestsCookieJar' is not JSON serializable

How would I store r.cookies so that it is available in all functions in my application but can vary between users?

You can't store the RequestsCookieJar, no, but if all you want are the names and values of the cookies, you can trivially convert the jar to a dictionary:

session['cookies'] = r.cookies.get_dict()

The RequestsCookieJar.get_dict() method also supports filtering by domain and path.

For future requests, the cookies parameter of requests.<METHOD>(...) calls accepts such a dictionary directly.
