notify-send not work as CGI script?

I write a cgi script in python just send a notification command,but that can not work for me.

Code:

#!/usr/bin/env python

#-*-coding=utf-8-*-



import cgi

import os



print 'Content-Type:text/html\n\n'



os.system("notify-send 'hello'")

And

Code:

djstava@Gateway:~/test$ notify-send 'hello'

is OK.

This is the error.

Code:

djstava@Gateway:/tmp$ cat notify-error 

libnotify-Message: Unable to get session bus: /bin/dbus-launch terminated abnormally with the following error: Autolaunch error: X11 initialization failed.

I can't actually see what is in your CODE tags because I am on my phone, but the problem is almost certainly the fact that the script is not being executed as the user with the X session, but rather the user your web server is setup to run under.

The problem is, you certainly don't want the web server running under your normal user account either.
