How to Use Cookies in Python Requests

I am trying to login to a page and access another link in the page.

payload={'username'=<username>,'password'=<password>}
with session() as s:
    r = c.post(<URL>, data=payload)
    print r
    print r.content

This is giving me a "405 Not Allowed" error. I checked the post method details using chrome developer tools and could see an api (URL/api/auth). I posted to that URL with the payload and it was working and i was getting a response similar to what i could see in the developer.

Unfortunately when trying to 'get' another url after login, i am still getting the content from the login page. Why is the login not sticking? Should i use cookies? I am a newbie, so i don't really know how to work with cookies.

You can use a session object. It stores the cookies so you can make requests, and it handles the cookies for you

s = requests.Session() 
# all cookies received will be stored in the session object

s.post(')
s.get(')

Docs:

You can also save the cookie data to an external file, and then reload them to keep session persistent without having to login every time you run the script:

From the documentation:

  1. get cookie from response

     url = '
 r = requests.get(url)
 r.cookies

    {'example_cookie_name': 'example_cookie_value'}

  2. give cookie back to server on subsequent request

     url = '
 cookies = {'cookies_are': 'working'}
 r = requests.get(url, cookies=cookies)`

Logic of Login

  • Many resource(pages, api) need authentication, then can access, otherwise 405 Not Allowed
  • Common authentication=grant access method are:
    • cookie
    • auth header
      • Basic xxx
      • Authorization xxx
