Python uses Requests to process sessions, maintain session status, share session information, etc

Preparation work: 1. Install Python: First, make sure that your computer has Python installed. You can access the Python official website（ https://www.python.org ）Download the latest version of Python. 2. Install dependency library: In order to use the Requests library, we need to install it. Run the following command from the command line to install the Requests library: pip install requests Next is a complete example of using the Requests library to process sessions: python import requests #Create a Session object session = requests.Session() #Send a GET request and maintain session state response = session.get('https://www.example.com/login') #Send POST request login payload = {'username': 'your_username', 'password': 'your_password'} response = session.post('https://www.example.com/login', data=payload) #Check login status if response.status_code == 200: Print ('Login successful ') else: Print ('Login failed ') #Send a request with session information response = session.get('https://www.example.com/protected_page') #Print the response content returned by the server print(response.text) #Close Session session.close() The above code uses the Session object of the Requests library to handle the session. Firstly, we created a Session object, sent a GET request to the login page, and then sent a POST request to log in. By using the post method in the Session object, we can keep the logged in session information in the session, so that subsequent requests will automatically carry this information. Finally, we sent a GET request with session information and printed the response content returned by the server. Summary: By using the Session object in the Requests library, we can simplify the process of processing sessions, maintain session state, and share session information. It provides a convenient way to handle tasks that require maintaining session state, such as logging in, tracking users, etc.
