How to Create a Login Session with Python Requests?

Estimated read time 2 min read

To create a login session with Python requests, you’ll need to perform the following steps:

  1. Import the requests library: import requests
  2. Define the login URL and data: You’ll need to know the URL where the login form is located, as well as the names of the form fields (usually “username” and “password”). You’ll also need to provide the username and password to log in with.
  3. Send a POST request to the login URL with the login data: Use the requests.post() method to send a POST request to the login URL with the login data.
  4. Check the response: The server will respond with a status code indicating whether the login was successful or not. You can check this code using the response.status_code attribute.
  5. Use the session object for subsequent requests: If the login was successful, you can use the requests.Session() object to maintain the session for subsequent requests. This will allow you to make authenticated requests to protected resources on the website.

Here’s some sample code to get you started:

import requests

# Define the login URL and data
login_url = 'https://example.com/login'
login_data = {
    'username': 'myusername',
    'password': 'mypassword'
}

# Send a POST request to the login URL with the login data
response = requests.post(login_url, data=login_data)

# Check the response status code
if response.status_code == 200:
    # Login successful
    session = requests.Session()
    session.post(login_url, data=login_data)
    
    # Use the session object for subsequent requests
    response = session.get('https://example.com/protected_resource')
    print(response.text)
else:
    # Login failed
    print('Login failed')

This code sends a POST request to the login URL with the login data. If the response status code is 200 (i.e. OK), the login was successful, and the code creates a session object and uses it to make subsequent requests. If the login failed, the code prints a message indicating that the login failed. Note that you’ll need to replace the URLs and login data with the appropriate values for your website.
