How to get cookie from an urllib.request
?
import urllib.request
import urllib.parse
data = urllib.parse.urlencode({
'user': 'user',
'pass': 'pass'
})
data = data.encode('utf-8')
request = urllib.request.urlopen('http://example.com', data)
print(request.info())
request.info()
returns cookies but not in very usable way.
response.info()
is a dict
type object. so you can parse any info you need. Here is a demo written in python3:
from urllib import request
from urllib.error import HTTPError
# declare url, header_params
req = request.Request(url, data=None, headers=header_params, method='GET')
try:
response = request.urlopen(req)
cookie = response.info().get_all('Set-Cookie')
content_type = response.info()['Content-Type']
except HTTPError as err:
print("err status: {0}".format(err))
return
You can now, parse cookie
variable as your application requirement.
I think using the requests package is a much better choice these days. Try this sample code that shows google setting cookies when you visit:
import requests
url = "http://www.google.com"
r = requests.get(url,timeout=5)
if r.status_code == 200:
for cookie in r.cookies:
print(cookie) # Use "print cookie" if you use Python 2.
Gives:
Cookie NID=67=n0l3ME1Jl3-wwlH7oE5pvxJ_CfU12hT5Kh65wh21bvE3hrKFAo1sJVj_UcuLCr76Ubi3yxENROaYNEitdgW4IttL43YZGlf8xAPl1IbzoLG31KP5U2tiP2y4DzVOJ2fA for .google.se/
Cookie PREF=ID=ce66d1288fc0d977:FF=0:TM=1407525509:LM=1407525509:S=LxQv7q8fju-iHJPZ for .google.se/
Just used the following code to get cookie from Python Challenge #17, hope it helps (Python 3.8 being used):
import http.cookiejar
import urllib
cookiejar = http.cookiejar.CookieJar()
cookieproc = urllib.request.HTTPCookieProcessor(cookiejar)
opener = urllib.request.build_opener(cookieproc)
response = opener.open(url)
for cookie in cookiejar:
print(cookie.name, cookie.value)
