无法使用 python 调用 dbus 中的 klipper 方法
我尝试使用 python 从 klipper 总线调用方法。但我没能做到。这是我尝试的：
>>> 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 <ProxyObject 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'

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownObject: No such object path '/org/kde/klipper'
如您所见，它设置了代理和接口。但我无法通过这个接口调用方法。
我能做些什么？我做错了什么？
编辑已解决：
好吧，当我查看“qdbusviewer”时，我看到了 klipper 的确切路径。 因此，
>> proxy = bus.get_object("org.kde.klipper","/org/kde/klipper")
将此行更改为：
>>> proxy = bus.get_object("org.kde.klipper","/klipper")
解决了问题。
我希望这篇文章可以帮助别人
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 <ProxyObject 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'

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

经过一番尝试，我发现了错误：
<代码>>> proxy = bus.get_object("org.kde.klipper","/org/kde/klipper")
必须是：
<代码>>> proxy = bus.get_object("org.kde.klipper","/klipper")
这解决了问题
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
看起来相当可怕。通过
bash调用qdbus可能会更简单：0 表示当前选择，1 表示下一个选择 - 依此类推。
Looks quite scarry. It might be simpler to call
qdbusthroughbash:0 is for current selection, 1 is for following one - and so on.
