Extracting Named Parameters from URLs in Flask

Suppose you have a URL like http://10.1.1.1:5000/login?username=alex&password=pw1 that you want your Flask app to handle. To access the parameters specified after the question mark, use request.args, not request.form.

from flask import request

@app.route('/login', methods=['GET', 'POST'])
def login():
    username = request.args.get('username')
    password = request.args.get('password')

This code retrieves the values of the username and password parameters, if they exist in the URL. You can then manipulate these parameters as needed in your Python script.
