How to Capture and Reuse Cookies in Python Web Scraping with Requests

Introduction

A user asked how to retrieve the response cookies from a Python web‑scraping request and use them in a second request, noting that without the correct cookies the server does not respond properly.

Implementation Steps

Send the first request and obtain the response.

Extract the cookie information from the response object.

Apply the extracted cookie to the second request.

Code Example

import requests

# First step: send request and get response
url_first = 'http://example.com/login'
payload_first = {'username': 'your_username', 'password': 'your_password'}
response_first = requests.post(url_first, data=payload_first)

# Second step: extract cookies from the response
cookies = response_first.cookies

# Third step: use the extracted cookies in the second request
url_second = 'http://example.com/some_protected_resource'
response_second = requests.get(url_second, cookies=cookies)

# response_second now contains data retrieved with the first request's cookies

Explanation of the Code

url_first

is the login page URL. payload_first contains the username and password required for login. response_first holds the server's response to the login request. cookies stores the cookies extracted from response_first. url_second is the URL of the protected resource that requires the logged‑in cookie. response_second is the response obtained after sending the second request with the extracted cookie.

Depending on the target website, additional security measures such as CSRF tokens or dynamically generated form fields may be required; always respect the site's robots.txt and terms of service when crawling.

An alternative approach using Selenium is mentioned, with an image illustrating how Selenium automatically follows redirects without extra handling.

Conclusion

The article provides a clear solution for extracting cookies from a Python requests response and reusing them in subsequent requests, helping readers solve common web‑scraping authentication challenges.
