Cannot call klipper methods in dbus with python

I try to call methods from klipper bus with python. But I could not make it. Here is what i try:

>>> import dbus
>>> bus = dbus.SessionBus()
>>> proxy = bus.get_object("org.kde.klipper","/org/kde/klipper")
>>> print proxy
<ProxyObject wrapping <dbus._dbus.SessionBus (session) at 0x7fc249da3bf0> :1.67 /org/kde/klipper at 0x7fc249dc16d0>
>>> iface = dbus.Interface(proxy,"org.kde.klipper.klipper")
>>> print iface
<Interface <Prox开发者_JAVA技巧yObject wrapping <dbus._dbus.SessionBus (session) at 0x7fc249da3bf0> :1.67 /org/kde/klipper at 0x7fc249dc16d0> implementing 'org.kde.klipper.klipper' at 0x7fc249dc1790>
>>> print iface.getClipboardContents()
ERROR:dbus.proxies:Introspect error on :1.67:/org/kde/klipper: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownObject: No such object path '/org/kde/klipper'

As you can see it sets both proxy and interface. But I cannot call methods via this interface.

What can I do? What am i doing wrong?

Edit Solved:

Well when i look to "qdbusviewer" I saw the exact path of klipper. So changing

>> proxy = bus.get_object("org.kde.klipper","/org/kde/klipper")

this line with this:

>>> proxy = bus.get_object("org.kde.klipper","/klipper")

Solves the problem.

I hope this post help someone

After some try, I found the the mistake: >>> proxy = bus.get_object("org.kde.klipper","/org/kde/klipper") must be: >>> proxy = bus.get_object("org.kde.klipper","/klipper") this solved the problem

Looks quite scarry. It might be simpler to call qdbus through bash:

import os
system("qdbus org.kde.klipper /klipper getClipboardHistoryItem 0")

0 is for current selection, 1 is for following one - and so on.
