How to mock a REST POST endpoint in Python

import json
from http.server import BaseHTTPRequestHandler, HTTPServer


class MockHandler(BaseHTTPRequestHandler):
    def do_POST(self):
        content_length = int(self.headers.get("Content-Length", 0))
        body = self.rfile.read(content_length) if content_length else b"{}"
        try:
            data = json.loads(body)
        except json.JSONDecodeError:
            data = {}

        resource_id = data.get("id", 1)
        response = {"id": resource_id, "status": "created"}

        self.send_response(201)
        self.send_header("Content-Type", "application/json")
        self.end_headers()
        self.wfile.write(json.dumps(response).encode())

    def log_message(self, format, *args):
        pass


def run_mock_server(port=8000):
    server = HTTPServer(("localhost", port), MockHandler)
    print(f"Mock server running on port {port}")
    try:
        server.handle_request()
    except KeyboardInterrupt:
        pass
    finally:
        server.server_close()
