We're back after a server migration that caused effbot.org to fall over a bit harder than expected. Expect some glitches.

The BaseHTTPServer module

This is a basic framework for HTTP servers, built on top of the SocketServer framework.

The following example generates a random message each time you reload the page. The path variable contains the current URL, which you can use to generate different contents for different URLs (as it stands, the script returns an error page for anything but the root path).

Example: Using the BaseHTTPServer module
# File: basehttpserver-example-1.py

import BaseHTTPServer
import cgi, random, sys

    "That's as maybe, it's still a frog.",
    "Albatross! Albatross! Albatross!",
    "It's Wolfgang Amadeus Mozart",
    "A pink form from Reading.",
    "Hello people, and welcome to 'It's a Tree'"
    "I simply stare at the brick and it goes to sleep.",

class Handler(BaseHTTPServer.BaseHTTPRequestHandler):

    def do_GET(self):
        if self.path != "/":
            self.send_error(404, "File not found")
        self.send_header("Content-type", "text/html")
            # redirect stdout to client
            stdout = sys.stdout
            sys.stdout = self.wfile
            sys.stdout = stdout # restore
    def makepage(self):
        # generate a random message
        tagline = random.choice(MESSAGES)
        print "<html>"
        print "<body>"
        print "<p>Today's quote: "
        print "<i>%s</i>" % cgi.escape(tagline)
        print "</body>"
        print "</html>"

PORT = 8000

httpd = BaseHTTPServer.HTTPServer(("", PORT), Handler)
print "serving at port", PORT
