试图理解如何在Python中使用多线程websockets，但似乎被一个线程卡住了

pip install asyncio
pip install websockets

import asyncio
import websockets
import threading

async def websocket_handler(websocket, path):
    # 处理WebSocket连接的逻辑
    while True:
        message = await websocket.recv()
        print(f"Received message: {message}")
        await websocket.send(f"Echoed message: {message}")

def start_websocket_server():
    # 启动WebSocket服务器的逻辑
    asyncio.set_event_loop(asyncio.new_event_loop())
    start_server = websockets.serve(websocket_handler, 'localhost', 8765)
    asyncio.get_event_loop().run_until_complete(start_server)
    asyncio.get_event_loop().run_forever()

def main():
    # 在主线程中启动WebSocket服务器
    websocket_thread = threading.Thread(target=start_websocket_server)
    websocket_thread.start()

    # 在主线程中执行其他任务
    while True:
        # 执行其他任务的逻辑
        pass

if __name__ == "__main__":
    main()
