Multithreaded web server in python

Question

I'm trying to create multithreaded web server in python, but it only responds to one request at a time and I can't figure out why. Can you help me, please?

#!/usr/bin/env python2 # -*- coding: utf-8 -*-  from SocketServer import ThreadingMixIn from  BaseHTTPServer import HTTPServer from SimpleHTTPServer import SimpleHTTPRequestHandler from time import sleep  class ThreadingServer(ThreadingMixIn, HTTPServer):     pass  class RequestHandler(SimpleHTTPRequestHandler):     def do_GET(self):         self.send_response(200)         self.send_header('Content-type', 'text/plain')         sleep(5)         response = 'Slept for 5 seconds..'         self.send_header('Content-length', len(response))         self.end_headers()         self.wfile.write(response)  ThreadingServer(('', 8000), RequestHandler).serve_forever() 

Answer 1

I have developed a PIP Utility called ComplexHTTPServer that is a multi-threaded version of SimpleHTTPServer.

To install it, all you need to do is:

pip install ComplexHTTPServer 

Using it is as simple as:

python -m ComplexHTTPServer [PORT] 

(By default, the port is 8000.)

Check this post from Doug Hellmann's blog.

from BaseHTTPServer import HTTPServer, BaseHTTPRequestHandler from SocketServer import ThreadingMixIn import threading  class Handler(BaseHTTPRequestHandler):      def do_GET(self):         self.send_response(200)         self.end_headers()         message =  threading.currentThread().getName()         self.wfile.write(message)         self.wfile.write('\n')         return  class ThreadedHTTPServer(ThreadingMixIn, HTTPServer):     """Handle requests in a separate thread."""  if __name__ == '__main__':     server = ThreadedHTTPServer(('localhost', 8080), Handler)     print 'Starting server, use <Ctrl-C> to stop'     server.serve_forever()
