There exist tools like CherryPy which will create a single-file Python HTTP server (based on BaseHTTPServer). This is a fair amount easier to work with than the raw BaseHTTPServer. For most cases, using a more complete framework will be preferable (see WebProgramming). -- IanBicking I like the BaseHttpServer because it is in the default Python distributions. I encourage all work towards putting a standard web framework into the default Python distribution. I'm not picky, just as long as something is chosen. -- LionKimbro [[DateTime(2005-01-25T04:53:53Z)]] |
BaseHTTPServer
You can use this to make a simple HTTP web server.
Official Documentation
[http://www.python.org/doc/2.3.4/lib/module-BaseHTTPServer.html BaseHTTPServer module documentation] - what we use directly
[http://www.python.org/doc/2.3.4/lib/module-SocketServer.html SocketServer module documentation] - behind the BaseHttpServer

20 s.wfile.write("<body><p>This is a test.</p>")
21 # If someone went to "http://something.somewhere.net/foo/bar/",
22 # then s.path equals "/foo/bar/".
23 s.wfile.write("<p>You accessed path: %s</p>" % s.path)

Discussion
I'd ultimately like to see a BaseHttpServer here that can both handle XML-RPC requests (with that request handler,) and normal web requests (with a custom handler.)
Yes- I know and love TwistedPython. But I want to make something that works in a single install. -- LionKimbro DateTime(2004-05-31T01:13:16Z)
I'd also like to add code here showing how to service a POST request.
