Python-socketio: Without any answer on socketio.emit

[alcupe]

We have a python code:

vToken = GetToken()

ListenPort = 'http://180.13.1.245:3013'
sio = socketio.AsyncClient()

loop = asyncio.get_event_loop()
start_timer = None


async def send_ping():
    global start_timer
    start_timer = time.time()
    await sio.emit('ping_from_client')


@sio.event
async def connect():
    print('connected to server')
    await send_ping()


@sio.event
async def pong_from_server():
    global start_timer
    latency = time.time() - start_timer
    print('latency is {0:.2f} ms'.format(latency * 1000))
    await sio.sleep(1)
    await send_ping()


async def start_server():
    await sio.connect(ListenPort)
    await sio.emit('report-client-register', data={'token': vToken, 'channelRole': 'client'})
    sio.on('report-client-rejection', {'token': vToken})
    sio.on('report-client-rooms', {'token': vToken})
    sio.on('push-broadcast-register', {'token': vToken})

if __name__ == '__main__':
    loop.run_until_complete(start_server())

How to fix it?

[miguelgrinberg]

What problem do you need to fix? The log doesn't show any problem.

[alcupe]

Hi.
The problem is that I do not have the response from the server when executing: sio.emit ('report-client-register', data = {'token': vToken, 'channelRole': 'client'}) and therefore the instructions below.

[miguelgrinberg]

Events do not have responses in Socket.IO. If the server is configured to send ACK packets, then you can add a callback to your emit, which will be called when the server acknowledges the event. The call() function combines the emit and the callback and makes it look like a single thing, so maybe that's what you are looking for.

Work fine. Thanks.
