How to programmatically log in to website App using Python

For this example, we are going to log in to a Django application. If it is another type of application, you only have to check the needed login form fields.

import requests
from bs4 import BeautifulSoup

USERNAME = 'username'  # put correct username here
PASSWORD = 'password'  # put correct password here

URL = 'https://your.url.com' # Change to your domain
LOGINURL = URL + '/login/'  # Change to your app login url
DATAURL = URL + 'url_data' # Change 

session = requests.session()

req_headers = {
    'Content-Type': 'application/x-www-form-urlencoded'
}


# to get csrfToken
r = session.get(LOGINURL,  headers=req_headers, allow_redirects=False)

soup = BeautifulSoup(r.text)
csrfToken = soup.find('input', attrs={'name': 'csrf_token'})['value']


formdata = {
    'username': USERNAME,
    'password': PASSWORD,
    'csrf_token': csrfToken,
}
# login post
r = session.post(LOGINURL, data=formdata, headers=req_headers, allow_redirects=False)

# We are logged in and we can read data
r2 = session.get(DATAURL)
