高延迟 Python Socket.Io

Question

我目前正在使用 Python socket.io and aiohttp to make a Server. My client is a nodejs socket.io client。我有一个使用发送函数发送当前时间的线程。来自 connect 事件的消息会立即收到，但来自 Thread 的消息仅在到达 ping_timeout 后才发送。日志显示事件是在达到超时之前发出的。我如何实现线程立即发送数据，而不是在达到超时后。

Client.js

const { io } = require("socket.io-client");
const socket = io("http://127.0.0.1:8080/");
socket.on('message', (data) => {console.log(data)});

Server.py

from threading import Thread
from time import time
from aiohttp import web
import socketio, asyncio

sio = socketio.AsyncServer(ping_timeout=1, logger=True, engineio_logger=True)
app = web.Application()
sio.attach(app)

@sio.event
async def connect(sid, environ):
    await sio.send('firstMessage')

async def sendLoop():
    while(True):
        await sio.send(f'DATA-{time()}')
        await asyncio.sleep(0.5)

Thread(target=asyncio.run, args=(sendLoop(),),daemon=True).start()
web.run_app(app)

由于登录仅打印到控制台，因此没有时间戳。然而，连接过程是 <1s
