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

There is no immediate way to do so, but it's not hard to do.

You can get a CookieJar object from the session with session.cookies, and use pickle to store it to a file.

A full example:

import requests, picklesession = requests.session()# Make some callswith open('somefile', 'wb') as f:    pickle.dump(session.cookies, f)

Loading is then:

session = requests.session()  # or an existing sessionwith open('somefile', 'rb') as f:    session.cookies.update(pickle.load(f))

The requests library uses the requests.cookies.RequestsCookieJar() subclass, which explicitly supports pickling and a dict-like API. The RequestsCookieJar.update() method can be used to update an existing session cookie jar with the cookies loaded from the pickle file.

After a call such as r = requests.get(), r.cookies will return a RequestsCookieJar which you can directly pickle, i.e.

import pickledef save_cookies(requests_cookiejar, filename):    with open(filename, 'wb') as f:        pickle.dump(requests_cookiejar, f)def load_cookies(filename):    with open(filename, 'rb') as f:        return pickle.load(f)#save cookiesr = requests.get(url)save_cookies(r.cookies, filename)#load cookies and do a requestrequests.get(url, cookies=load_cookies(filename))

If you want to save your cookies in human-readable format, you have to do some work to extract the RequestsCookieJar to a LWPCookieJar.

import cookielibdef save_cookies_lwp(cookiejar, filename):    lwp_cookiejar = cookielib.LWPCookieJar()    for c in cookiejar:        args = dict(vars(c).items())        args['rest'] = args['_rest']        del args['_rest']        c = cookielib.Cookie(**args)        lwp_cookiejar.set_cookie(c)    lwp_cookiejar.save(filename, ignore_discard=True)def load_cookies_from_lwp(filename):    lwp_cookiejar = cookielib.LWPCookieJar()    lwp_cookiejar.load(filename, ignore_discard=True)    return lwp_cookiejar#save human-readabler = requests.get(url)save_cookies_lwp(r.cookies, filename)#you can pass a LWPCookieJar directly to requestsrequests.get(url, cookies=load_cookies_from_lwp(filename))

Expanding on @miracle2k's answer, requests Sessions are documented to work with any cookielib CookieJar. The LWPCookieJar (and MozillaCookieJar) can save and load their cookies to and from a file. Here is a complete code snippet which will save and load cookies for a requests session. The ignore_discard parameter is used to work with httpbin for the test, but you may not want to include it your in real code.

import osfrom cookielib import LWPCookieJarimport requestss = requests.Session()s.cookies = LWPCookieJar('cookiejar')if not os.path.exists('cookiejar'):    # Create a new cookies file and set our Session's cookies    print('setting cookies')    s.cookies.save()    r = s.get('http://httpbin.org/cookies/set?k1=v1&k2=v2')else:    # Load saved cookies from the file and use them in a request    print('loading saved cookies')    s.cookies.load(ignore_discard=True)    r = s.get('http://httpbin.org/cookies')print(r.text)# Save the session's cookies back to the files.cookies.save(ignore_discard=True)
