How to stop a simplehttpserver in python from httprequest handler?

Question

I am new to python and wrote a simple httpserver in python. I am trying to shut down the server from the request to the server. How can I achieve this functionality of calling a function of the server from the handler?

class MyHandler(SimpleHTTPRequestHandler):
    def do_GET(self):
        if self.path == '/shutdown':
            pass # I want to call MainServer.shutdown from here


class MainServer()
    def __init__(self, port = 8123):
        self._server = HTTPServer(('0.0.0.0', port), MyHandler)
        self._thread = threading.Thread(target = self._server.serve_forever)
        self._thread.deamon = True 


    def start(self):
        self._thread.start()

    def shut_down(self):
        self._thread.close()

In short, do not use server.serve_forver(..). The request handler has a self.server attribute that you can use to communicate with the main server instance to set some sort of flag that tell the server when to stop.

import threading
from BaseHTTPServer import BaseHTTPRequestHandler,HTTPServer

class MyHandler(BaseHTTPRequestHandler):
    def do_GET(self):
        if self.path == '/shutdown':
            self.server.running = False


class MainServer:
    def __init__(self, port = 8123):
        self._server = HTTPServer(('0.0.0.0', port), MyHandler)
        self._thread = threading.Thread(target=self.run)
        self._thread.deamon = True 

    def run(self):
        self._server.running = True
        while self._server.running:
            self._server.handle_request()

    def start(self):
        self._thread.start()

    def shut_down(self):
        self._thread.close()

m = MainServer()
m.start()
