Question

我实现了一个简单的服务器来与客户端通信。大约30秒后，服务器宣布客户端已断开连接。我试图增加服务器的ping_travler和ping_timeout参数，但这似乎没有帮助。

我想知道断开连接是由服务器还是由客户端引起的。我们如何保持客户端和服务器之间的连接？

我的代码如下：

服务器：

# coding:utf-8
import json
import socketio
import uvicorn

# ping_travler=60, ping_timeout=300, always_connect=True
sio = socketio.AsyncServer(async_mode='asgi')
app = socketio.ASGIApp(sio)

@sio.event
def disconnect(sid):
    print('disconnect:', sid)

@sio.event
def connect(sid, environ):
    sio.start_background_task(target=send_message)
    print("connect ", sid)

@sio.on('message', namespace='/server_conn')
async def receive_message(sid, data):
    pass

async def send_message():
    while True:
        await sio.sleep(0.00001)
        await sio.emit('receive_message', json.dumps('123'))

if __name__ == '__main__':
    uvicorn.run(app, host='127.0.0.1', port=5000)

客户：

# coding:utf-8
import asyncio
import json
import time

from flask_socketio import socketio

sio = socketio.AsyncClient(logger=True, engineio_logger=False)

t = time.time()

@sio.event
def connect():
    sio.start_background_task(target=send_message)

@sio.event
def disconnect():
    print('client disconnected')


async def send_message():
    while True:
        await sio.sleep(0.2)
        await sio.send(json.dumps('123'), namespace='/server_rece')

@sio.event
async def receive_message(message):
    print(message)
    print(time.time() - t)  # Disconnected in about 30 seconds

async def start_sio_server():
    await sio.connect('http://127.0.0.1:5000')

def main():
    LOOP = asyncio.new_event_loop()
    asyncio.set_event_loop(LOOP)
    LOOP.run_until_complete(start_sio_server())
    LOOP.run_forever()

if __name__ == '__main__':
    main()

谢谢。
