[SOLVED] notify-send not work as CGI script?

djstava · 05-30-2010, 09:30 PM

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.


** (notify-send:4642): CRITICAL **: dbus_g_proxy_connect_signal: assertion `DBUS_IS_G_PROXY (proxy)' 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.

Yes,I change the apache2's default user www-data to my system user djstava,and it works,ONLY need the $DISPLAY.Just like this,

Code:

os.system("DISPLAY=:0.0; notify-send 'hello'")

Thank you.
