Multithreaded web server in python

Check this post from Doug Hellmann's blog.

from BaseHTTPServer import HTTPServer, BaseHTTPRequestHandlerfrom SocketServer import ThreadingMixInimport threadingclass 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')        returnclass 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()

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.)

In python3, you can use the code below (https or http):

from http.server import HTTPServer, BaseHTTPRequestHandlerfrom socketserver import ThreadingMixInimport threadingUSE_HTTPS = Trueclass Handler(BaseHTTPRequestHandler):    def do_GET(self):        self.send_response(200)        self.end_headers()        self.wfile.write(b'Hello world\t' + threading.currentThread().getName().encode() + b'\t' + str(threading.active_count()).encode() + b'\n')class ThreadingSimpleServer(ThreadingMixIn, HTTPServer):    passdef run():    server = ThreadingSimpleServer(('0.0.0.0', 4444), Handler)    if USE_HTTPS:        import ssl        server.socket = ssl.wrap_socket(server.socket, keyfile='./key.pem', certfile='./cert.pem', server_side=True)    server.serve_forever()if __name__ == '__main__':    run()

You will figure out this code will create a new thread to deal with every request.

Command below to generate self-sign certificate:

openssl req -x509 -newkey rsa:4096 -nodes -out cert.pem -keyout key.pem -days 365

If you are using Flask, this blog is great.
