How to Extract Cookies After Logging into a Webpage with Python?

Logging into a Webpage and Extracting Cookies for Subsequent Use in Python

To access a webpage that requires authentication, it is necessary to obtain the cookies set during the login process. This article outlines a method to log into a webpage using Python 2.6 and retrieve the cookies for later use.

Utilizing the requests library, the following code snippet demonstrates how to achieve this:

<code class="python">from requests import session

payload = {
    'action': 'login',
    'username': USERNAME,
    'password': PASSWORD
}

with session() as c:
    c.post('http://example.com/login.php', data=payload)
    response = c.get('http://example.com/protected_page.php')
    print(response.headers)
    print(response.text)</code>

This script establishes a session with the website, logs in by sending the POST parameters, and then performs a request to a protected page. The session object automatically handles cookie management, so the cookies obtained during the login process will be used in subsequent requests.

This approach is convenient and straightforward, and it allows for easy retrieval and utilization of cookies without the need for complex cookie manipulation mechanisms.
