错误设置状态与DBUS

Question

我得到的错误，当我尝试设置状态与使用python， 这DBUS换位思考换位思考是我从不同的来源

## getting status from clementine music player 

import dbus 

# Clementine lives on the Session bus 
session_bus = dbus.SessionBus() 

# Get Clementine's player object, and then get an interface from that object, 
# otherwise we'd have to type out the full interface name on every method call. 
player = session_bus.get_object('org.mpris.clementine', '/Player') 
iface = dbus.Interface(player, dbus_interface='org.freedesktop.MediaPlayer') 

# Call a method on the interface 
metadata = iface.GetMetadata() 
print metadata["title"]+' - '+metadata["artist"] 
status = metadata["title"]+' - '+metadata["artist"]

当我运行了这个代码脚本， 我收到以下错误。

[email protected]:~$ python clementine.py 
onelove - Blue 

(clementine.py:6142): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap", 
onelove - Blue is not supported by /org/freedesktop/Telepathy/Account/gabble/jabber/abcd_40gmail_2ecom0 

我做错了什么？或者这些功能已被弃用？

试试这与当前曲目在Clementine玩到更新同情的状态：

import dbus 
session_bus = dbus.SessionBus() 
player = session_bus.get_object('org.mpris.clementine', '/Player') 
iface = dbus.Interface(player, dbus_interface='org.freedesktop.MediaPlayer') 
metadata = iface.GetMetadata() 
status = "♫ ".decode('utf8')+metadata["title"]+' - '+metadata["album"]+" ♫".decode('utf8') 
print status 
from gi.repository import TelepathyGLib as Tp 
from gi.repository import GObject 
loop = GObject.MainLoop() 
am = Tp.AccountManager.dup() 
am.prepare_async(None, lambda *args: loop.quit(), None) 
loop.run() 
am.set_all_requested_presences(Tp.ConnectionPresenceType.AVAILABLE, 
'available', status)

下面是SimplePresence API的SetPresence调用的API规范：http://telepathy.freedesktop.org/spec/Connection_Interface_Simple_Presence.html#Method:SetPresence

我认为问题是，你要存在设置为无效状态 - 你只允许状态设置为一连接管理器可以识别 - 例如可用。您可以设置任何您喜欢的消息。

所以，你的代码应该读的东西，如：

simple_presence.SetPresence("Available", status)
