find ( 'input', attrs = " ) p = session.
In particular, we'll need to use its Session object, which will capture and store any cookie information for us.įrom bs4 import BeautifulSoup import requests LOGIN_URL = "" def get_authenticity_token ( html ): soup = BeautifulSoup ( html, "html.parser" ) token = soup. To scrape data that is behind login forms, we'll need to replicate this behavior using the requests library. Every time you access one of the site's pages, the site checks to make sure the cookie is valid and that you are allowed to access the page you are trying to reach. Once login is successful, a cookie is then stored in your browser's memory. Is this a valid user?" If the credentials are valid, you are redirected to some page within the app (like the user's home page). Essentially, it's saying "Here are the credentials I was given.

The user and password fields are then checked against the site's database to validate the information. When you enter your email and password into the form and press login, the first line in the highlighted red box tells us that the form data is sent via an HTTP POST request to (seen in the method and action fields, respectively).
WEBSCRAPER LOGIN WEBSITE CODE
This will bring you to the code that is responsible for the form and allow you to find the details required. The best way to find these details is by launching your browser's developer tools inside one of the input fields (like username/email).
While this will include some sort of username/email and password, it will likely include a token and possibly other details. Here's an example from Goodreads:įrom there, you'll need to find the necessary details of the login form. I find the best way to do this is by finding the page that is solely for login. While we'll use Goodreads here, the same concepts apply to most websites.įirst, you'll need to dig into how the site's login forms work.
If you'd like to jump straight to the code, you can find it on my Github.
WEBSCRAPER LOGIN WEBSITE HOW TO
This post walks through how to tackle the problem. Thankfully, with a little understanding of how HTML forms work, Python's requests library makes this doable with a few lines of code. One small complexity was that the user's book reviews were not public, which meant you needed to log into Goodreads to access them. It sounded like a fun little scraping project to me. The other day a friend asked whether there was an easier way for them to get 1000+ Goodreads reviews without manually doing it one-by-one.
