如何将 python Socket.IO 与 Qt 集成

import sys
import socketio
from PyQt5.QtCore import QThread
from PyQt5.QtWidgets import QApplication


class ServerConnection(QThread):

    def __init__(self):
        QThread.__init__(self)
        self.sio = socketio.AsyncClient(reconnection=True, reconnection_attempts=3,
                   reconnection_delay=5, reconnection_delay_max=5, logger=True)

    'thread run function'
    def run(self) -> None:
        self.sio.connect(url="...",socketio_path="/...", transports="websocket")
        self.sio.on('connect', self.connect, namespace=None)
        self.sio.on('socket_connected', self.socket_connected, namespace=None)
        self.sio.on('connect_error', self.connect_error, namespace=None)
        self.sio.on('/client_Unlock', self.client_unlock_ack, namespace=None)

    # @sio.on('/client_unlock')
    'custom event from server, on receiving, this socketio thread needs to inform main GUI'
    async def client_unlock_ack(self, data):
            print("")
            'from here i want to call pyqt GUI main class function'

    # @sio.event
    'connection established status'
    def connect(self):
        print('Server Connection established!')

    # @sio.on("socket_connected")
    'socket connection status check'
    async def socket_connected(self, message):
        print("Socket Connected!", message)

    # @sio.event
    def connect_error(self, data):
        print('Connection error!', data)

    # @sio.on('disconnect' or 'socket_disconnected')
    def disconnect(self):
        print('Disconnected!')

'main function call'
def main():
    app = QApplication(sys.argv)
    con = ServerConnection()
    con.start()
    sys.exit(app.exec())


if __name__ == "__main__":
    main()

'GUI 类是一个 QMainWindow 应用程序，它处理我的应用程序的其他功能。 Socketio 线程连接是从 GUI 主线程触发的。基本上，GUI主启动->从GUI线程调用Socketio线程->一旦我们在socketio线程类中接收到socketio客户端解锁事件->来自client_unlock_ack，我需要向GUI主线程触发一个信号来调用成员函数'。请指导。

没有必要使用线程，因为您可以使用 asyncqt 等库，以便 Qt 与 asyncio 一起工作，避免使用 QThreads 增加不必要的复杂性

        self.sio.on("disconnect", self._handle_disconnect, namespace=None)

    with loop:
