Question

I’m writing a small web server in Python, using BaseHTTPServer and a custom subclass of BaseHTTPServer.BaseHTTPRequestHandler. Is it possible to make this listen on more than one port?

What I’m doing now:

class MyRequestHandler(BaseHTTPServer.BaseHTTPRequestHandler):   def doGET   [...]  class ThreadingHTTPServer(ThreadingMixIn, HTTPServer):      pass  server = ThreadingHTTPServer(('localhost', 80), MyRequestHandler) server.serve_forever() 

Answer 1

Sure; just start two different servers on two different ports in two different threads that each use the same handler. Here’s a complete, working example that I just wrote and tested. If you run this code then you’ll be able to get a Hello World webpage at both http://localhost:1111/ and http://localhost:2222/

from threading import Thread from SocketServer import ThreadingMixIn from BaseHTTPServer import HTTPServer, BaseHTTPRequestHandler  class Handler(BaseHTTPRequestHandler):     def do_GET(self):         self.send_response(200)         self.send_header('Content-type', 'text/plain')         self.end_headers()         self.wfile.write('Hello World!')  class ThreadingHTTPServer(ThreadingMixIn, HTTPServer):     daemon_threads = True  def serve_on_port(port):     server = ThreadingHTTPServer(('localhost',port), Handler)     server.serve_forever()  Thread(target=serve_on_port, args=[1111]).start() serve_on_port(2222) 

update:

This also works with Python 3 but three lines need to be slightly changed:

from socketserver import ThreadingMixIn from http.server import HTTPServer, BaseHTTPRequestHandler 

and

self.wfile.write(bytes('Hello World!', 'utf-8'))
