Python request module - Getting response cookies

Question

I am using python 3.3 and the request module. And I am trying understand how to retrieve cookies from a response. The request documentation says:

url = 'http://example.com/some/cookie/setting/url'
r = requests.get(url)

r.cookies['example_cookie_name']

That doesn't make sense, how do you get data from a cookie if you don't already know the name of the cookie? Maybe I don't understand how cookies work? If I try and print the response cookies I get:

<<class 'requests.cookies.RequestsCookieJar'>[]>

Thanks

Solution 1

You can retrieve them iteratively:

import requests

r = requests.get('http://example.com/some/cookie/setting/url')

for c in r.cookies:
    print(c.name, c.value)

Solution 2

I got the following code from HERE:

from urllib2 import Request, build_opener, HTTPCookieProcessor, HTTPHandler
import cookielib

#Create a CookieJar object to hold the cookies
cj = cookielib.CookieJar()
#Create an opener to open pages using the http protocol and to process cookies.
opener = build_opener(HTTPCookieProcessor(cj), HTTPHandler())

#create a request object to be used to get the page.
req = Request("http://www.about.com")
f = opener.open(req)

#see the first few lines of the page
html = f.read()
print html[:50]

#Check out the cookies
print "the cookies are: "
for cookie in cj:
    print cookie

See if this works for you.

Cookies are stored in headers as well. If this isn't working for you, check your headers for:

"Set-Cookie: Name=Value; [Expires=Date; Max-Age=Value; Path=Value]"
