Set new cookie between requests with Python requests
I am doing this right now, but on the last line with is TypeError: expected string or buffer
not working.
import requests
from urllib.parse import urlparse
url = 'some url'
s = requests.Session()
s.headers.update({
'Origin':urlparse(url).netloc,
'Referer':url
})
r = s.get(url)
s.cookies['cookie1'] = 25
s.cookies['cookie2'] = 25
r = s.post(
url,
{'param':'value1', 'param2':'value2'},
headers={'X-Requested-With':'XMLHttpRequest'}
)
What is the correct way to update cookies on use Session
? I'm new to Python, so I might be confusing something. Using Python 3.4.1.

Cookie values are strings, not integers. Install them as such:
s.cookies['cookie1'] = '25'
s.cookies['cookie2'] = '25'
Demo:
>>> import requests
>>> from urllib.parse import urlparse
>>> url = 'http://httpbin.org/cookies'
>>> s = requests.Session()
>>> s.headers.update({
... 'Origin':urlparse(url).netloc,
... 'Referer':url
... })
>>> r = s.get(url)
>>> s.cookies['cookie1'] = '25'
>>> s.cookies['cookie2'] = '25'
>>> r = s.get(url, headers={'X-Requested-With':'XMLHttpRequest'})
>>> print(r.text)
{"cookies": {"cookie1": "25", "cookie2": "25"}}
