        data['pass'] = PASSW
        data['login'] = 'Log In'

        r = self.s.post(LOGIN_URL , data=data)
        print r.text

fb = facebook()

why doesn't the final post request is working on FACEBOOK_URL = "https://m.facebook.com/" but on LOGIN_URL = "https://m.facebook.com/login.php?refsrc=https%3A%2F%2Fm.facebook.com%2F&refid=8" and similar links like it...?

Puh i dont know, i just tried some links and that one worked. Propably there are more alternatives..

Code not working. Please update.

It's been 6 years. Probably the login mechanism changed @stark821.

So now is it impossible to login Facebook through Http Requests ?

You can do It, first extract the input forums then input your fields, I did it a long time ago but do not know if it works

from bs4 import BeautifulSoup

def login(email, password):
    # Set up session
    session = requests.Session()

    # Set headers
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'
    }
    session.headers.update(headers)

    # Get login page
    response = session.get('https://www.facebook.com/')
    soup = BeautifulSoup(response.content, 'html.parser')

    # Extract form data and input fields
    form_data = {}
    for input_field in soup.find_all('input'):
        if input_field.has_attr('name'):
            form_data[input_field['name']] = input_field.get('value', '')

    # Fill in form data
    form_data['email'] = email
    form_data['pass'] = password

    # Submit form
    response = session.post('https://www.facebook.com/login.php', data=form_data)

    # Check if login was successful
    if 'Find Friends' in response.text:
        print('Login successful!')
    else:
        print('Login failed.')
        print(form_data)

Example usage

login('example@gmail.com', 'passcode')

You are a legend bro 🤍
