How do I connect dbus and policykit to my function in python?

Question

I am making a python application that has a method needing root privileges. From https://www.freedesktop.org/software/polkit/docs/0.105/polkit-apps.html, I found Example 2. Accessing the Authority via D-Bus which is the python version of the code below, I executed it and I thought I'd be able to get root privileges after entering my password but I'm still getting "permission denied" on my app. This is the function I'm trying to connect

import dbus

bus = dbus.SystemBus()
proxy = bus.get_object('org.freedesktop.PolicyKit1', '/org/freedesktop/PolicyKit1/Authority')
authority = dbus.Interface(proxy, dbus_interface='org.freedesktop.PolicyKit1.Authority')

system_bus_name = bus.get_unique_name()

subject = ('system-bus-name', {'name' : system_bus_name})
action_id = 'org.freedesktop.policykit.exec'
details = {}
flags = 1            # AllowUserInteraction flag
cancellation_id = '' # No cancellation id

result = authority.CheckAuthorization(subject, action_id, details, flags, cancellation_id)

print result

Answer 1

In the python code you quoted, does result indicate success or failure? If it fails, you need to narrow down the error by first of all finding out what the return values of bus, proxy, authority and system_bus_name are. If it succeeds, you need to check how you are using the result.

Well, i think it succeeds as long as the right password is entered. However, I'm still at a lost as I do not know how to use result. I've tried the docs but couldn't come up with anything concrete. – Farr

Here is an example from the aptdaemon docs – Lexicologist
