如何为两个单独的 Dbus Python 程序创建 Dbus Mainloop

Question

我有一个 python 进程监视 Dbus 服务并与之交互（NetworkManager）

目前这在主程序的自己的线程中运行

import dbus.mainloop.glib
import NetworkManager

PYTHON3 = sys.version_info >= (3, 0)
if PYTHON3:
    from gi.repository import GObject as gobject
    from gi.repository import GLib as glib
else:
    import gobject

class NetworkController(threading.Thread):

    def __init__(self, run_daemon_mode=False):
        # Set up DBus loop
        self.loop = None
        dbus.mainloop.glib.threads_init()
        dbus.mainloop.glib.DBusGMainLoop(set_as_default=True)
        
        if PYTHON3:
            self.loop = glib.MainLoop()
        else:
            self.loop = gobject.MainLoop()
            gobject.threads_init()

        #Create the thread
        super(NetworkController, self).__init__(daemon=run_daemon_mode)

    def run(self):
        """
        Method to run the DBus main loop (on a thread)
        """

        # NetworkManager init stuff...
        
        logger.debug("Starting Network Controller loop.")
        self.loop.run()
        logger.debug("Network Controller loop has exited.")

def main(argv):
    
    args=cli(argv) 

    #create network controller object but don't start the thread
    network_con = network_controller.NetworkController(True)
    network_con.start()     #

    try:
        while True:

我现在需要添加一个线程来控制我的也使用 Dbus 的蓝牙 GATT 服务（pyBluez 实现）。 如何构建我的代码以让每个进程在它自己的线程中运行并使用 Dbus。

谢谢！

我创建了我的新 class，它使用 Dbus 并且是一个单独的线程，就像我创建我的第一个 class 一样。 然后从我的主程序中调用 class 构造函数并启动每个线程。

class AnotherGlibMainloop(threading.Thread):

def __init__(self, run_daemon_mode=False):
    # Set up DBus loop
    self.loop = None
    dbus.mainloop.glib.threads_init()
    dbus.mainloop.glib.DBusGMainLoop(set_as_default=True)
    
    if PYTHON3:
        self.loop = glib.MainLoop()
    else:
        self.loop = gobject.MainLoop()
        gobject.threads_init()

    #Create the thread
    super(NetworkController, self).__init__(daemon=run_daemon_mode)

def run(self):
    """
    Method to run the DBus main loop (on a thread)
    """

    # NetworkManager init stuff...
    
    logger.debug("Starting Another Glib Mainloop.")
    self.loop.run()
    logger.debug("Another Glib Mainloop has exited.")

def main(argv):    args=cli(argv) 

#create network controller object but don't start the thread
network_con = network_controller.NetworkController(True)
network_con.start()     #

another_glib_mainloop = AnotherGlibMainloop(True)
another_glib_mainloop.start()

try:
    while True:
