Python Websockets 连接被拒绝 ERR 111

如何解决Python Websockets 连接被拒绝 ERR 111

我正在尝试使用 Websockets 作为网络部分在 Python 中创建一个文本游戏。使用提供的文档，一切都很好。但是，我需要创建一个 Webserver 类，以便能够注入连接，而不是将其作为参数传递给流程中存在的每个函数。这在文档中并没有真正涵盖。所以我搜索并找到了这个实现

import sys
from websockets import connect


class WebsocketHandler:
    def __await__(self):
        return self._async_init().__await__()

    async def _async_init(self):
        self._conn = connect("ws://127.0.0.1:5678/")
        self.websocket = await self._conn.__aenter__()
        return self

    async def close(self):
        await self._conn.__aexit__(*sys.exc_info())

    async def send(self,message):
        await self.websocket.send(message)

    async def receive(self):
        return await self.websocket.recv()

这对我的用例来说似乎没问题。但是尝试使用它时，我收到了 ConnectionRefused 错误 111。

这是游戏的实现（不是真正的游戏，更像是对它的模拟）。

import asyncio

from web.websockets.WebsocketHandler import WebsocketHandler


async def sendMessage(message):
    ws = await WebsocketHandler()
    await ws.send(message)


async def getMessage():
    ws = await WebsocketHandler()
    data = await ws.receive()
    return data


async def startGame():
    while True:
        # createCharacter
        # play
        # time to send a message
        await sendMessage("welcome choose!")
        print(await getMessage())
        await sendMessage("do a move!")
        print(await getMessage())
        await sendMessage("you did a move! do another!")
        print(await getMessage())


if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    loop.run_until_complete(startGame())

完整的错误信息是这样的

有人知道为什么会这样吗？提前致谢！
