in python 3, start an http server, when a request is received, save the GET query parameter in file code.txt and shutdown the server

http-server.py

from http.server import BaseHTTPRequestHandler, HTTPServer
import urllib.parse

class SimpleHTTPRequestHandler(BaseHTTPRequestHandler):
    def do_GET(self):
        # Parse the query parameters from the URL
        parsed_path = urllib.parse.urlparse(self.path)
        query_params = urllib.parse.parse_qs(parsed_path.query)

        # Extract the 'code' parameter if it exists
        code = query_params.get('code', [None])[0]

        # Save the code to a file
        if code is not None:
            with open('code.txt', 'w') as f:
                f.write(code)

                # Send a response back to the client
                self.send_response(200)
                self.send_header('Content-type', 'text/html')
                self.end_headers()
                self.wfile.write(b'Code received and saved. Shutting down the server.')

                # Shut down the server
                self.server.shutdown()
                return

    print(f'Starting httpd on port {port}...')
    httpd.serve_forever()
