Python dbus获取对象集超时

代码：

=============
错误：
dbus.exceptions.DBusException:org.freedesktop.dbus.Error.TimedOut:org.freedesktop.sssd.infopipe的激活超时

如果DBUS出现问题，则“获取_对象”将花费很长时间。如何设置超时以缩短时间？

既不

获取对象

也不

按名称启动服务

都不支持超时。 作为一种解决方法，您可以在

get\u object

之前直接使用

call\u blocking

，如下所示：

def get_user_totp_status (user_name = ''):
    key_name = 'tfaEnable'

    try:
        bus = dbus.SystemBus()
    except:
        print "connect dbus error!"
        sys.exit(1)

    infopipe_obj = bus.get_object("org.freedesktop.sssd.infopipe", "/org/freedesktop/sssd/infopipe")
    ifp = dbus.Interface(infopipe_obj,dbus_interface='org.freedesktop.sssd.infopipe')
    print "get user totp status from dbus error!"

    result = ifp.GetUserAttr(user_name, [key_name])
    user_totp_status = 'True'
    if result:
        for status in result[key_name]:
            user_totp_status = status

    return user_totp_status

import dbus
from _dbus_bindings import BUS_DAEMON_IFACE, BUS_DAEMON_NAME, BUS_DAEMON_PATH

bus = dbus.SystemBus()

timeout = 2
flags = 0
bus_name = "org.freedesktop.sssd.infopipe"

try:
    bus.call_blocking(BUS_DAEMON_NAME, BUS_DAEMON_PATH,
                      BUS_DAEMON_IFACE,
                      'StartServiceByName',
                      'su', (bus_name, flags), timeout=timeout)

    infopipe_obj = bus.get_object("org.freedesktop.sssd.infopipe", "/org/freedesktop/sssd/infopipe")

except dbus.exceptions.DBusException as e:
    print("The chosen bus is not available: %s", e)
