Twisted execute python file

Question

Is there any way to get a twisted webserver to execute a python file like cgi on a conventional webserver? So, when i navigated to a directory, i could execute python within a seperate file?

I have created a basic webserver, but it only returns static content like text or HTML files:

from twisted.web.server import Site
from twisted.web.static import File
from twisted.internet import reactor

resource = File('/root')
factory = Site(resource)
reactor.listenTCP(80, factory)
reactor.run()

I understand why it may not be possible, but i couldn't find any documentation. Thanks

EDIT: I found a solution. Instead of going through the hassle of directories, i'm simply parsing GET requests and treating them like fake files. The CGI is executed within the main file.

THanks

Do you want actual CGI or do you just want easily scriptable resources written in Python, not conforming to any particular standard? — Jean-Paul Calderone, Apr 26 '13 at 12:07

Found this example that might do what you want.

Take a look Twisted Web Docs for some more info. Search the page for CGI.

from twisted.internet import reactor
from twisted.web import static, server, twcgi

root = static.File("/root")
root.putChild("cgi-bin", twcgi.CGIDirectory("/var/www/cgi-bin"))
reactor.listenTCP(80, server.Site(root))
reactor.run()

This works, though it's probably not the best idea (you'd have to run it as root to bind to port 80 and on Linux, and a number of other Unix like systems, such as FreeBSD, you'd be serving up the */root/* (the 'root' user's home) directory. – Jim Dennis Apr 26 '13 at 05:51
This worked for me. The import part of this solution is the root.putChild("cgi-bin", twcgi.CGIDirectory("/var/www/cgi-bin")) line. The rest of it might need tweaking, and you might want to use alternate directory names / paths.The concept is spot on though. – BuvinJ Oct 09 '15 at 21:05

You would typically use the Twisted WSGI server for that.

http://twistedmatrix.com/documents/12.3.0/web/howto/web-in-60/wsgi.html

It doesn't exactly execute the Python file, but calls an "application". But that's better since it doesn't have to start a new Python process.

You can also use the twisted CGI support, which will execute the file, but using Twisted to run Python scripts with CGI is a bit like using a sports car as a tractor.
