Question

我使用quart作为网络游戏的后端。我有一个 game事件循环的存根和一个优先级队列，当优先级队列中的内容完成时，游戏循环将进行进一步处理，然后需要向玩家发送更新。这是游戏事件循环的简化版本：

async def game_loop(
    pq_event: multiprocessing.connection.Connection,
    ws_event: multiprocessing.connection.Connection,
):
    while True:
        # FIXME: This may block the concurrency
        ready, _, _ = select([pq_event, ws_event], [], [])
        which = random.choice(ready)
        if which == pq_event:
            event = pq_event.recv()
        elif which == ws_event:
            event = ws_event.recv()

        # for now all events are printed
        print(event)

我认为用game_loop装饰quart.copy_current_websocket_context可以让我使用全局websocket对象将内容发送给玩家，但事实并非如此：

Traceback (most recent call last):
  File "/usr/local/bin/backend-server", line 3, in <module>
    from backend import main
  File "/usr/local/lib/python3.7/site-packages/backend/main.py", line 7, in <module>
    from .loop import setup_pqueue, run_reactor, game_loop
  File "/usr/local/lib/python3.7/site-packages/backend/loop.py", line 53, in <module>
    ws_event: multiprocessing.connection.Connection,
  File "/usr/local/lib/python3.7/site-packages/quart/ctx.py", line 299, in copy_current_websocket_context
    raise RuntimeError('Attempt to copy websocket context outside of a websocket context')
RuntimeError: Attempt to copy websocket context outside of a websocket context

确实，我使用了错误的装饰器，但是我想要实现的是通过websocket向玩家发送消息，对我需要做什么有所了解？

如何通过@ so.websocket装饰功能之外的websocket向客户端发送消息？
