How Can I Successfully Log into a Website Using Python's Requests Module?

Logging into a Website with Python Requests: Cookies and HTTP Authorization

Problem:

A user is unable to log into a website using Python's Requests module due to issues with cookie handling. The code utilizes requests.post but yields incorrect results.

Solution:

HTTP Authorization vs. Cookies

HTTP authorization involves sending the user's credentials directly as part of the HTTP header. On the other hand, cookies allow the server to maintain state by storing information on the client's computer.

Correct Cookie Usage

In the provided code, the user created a dictionary called ck and passed it as an argument to requests.post. However, this dictionary should be passed as a data parameter instead.

Corrected Code

ck = {'inUserName': 'USERNAME/EMAIL', 'inUserPass': 'PASSWORD'}
r = requests.post(url, data=ck)

Maintaining Login Status

To stay logged in for an extended period, a web session must be preserved. This can be achieved using a requests.Session class. By default, Requests creates a new session instance for each request.

Suggested Code Using Session

with requests.Session() as session:
    login_data = {'inUserName': 'USERNAME/EMAIL', 'inUserPass': 'PASSWORD'}
    response = session.post(url, data=login_data)

    # Check login status. If successful, make subsequent requests using the same session
    if response.status_code == 200:
        safe_response = session.get('protected_url')
        print(safe_response.text)
