can not reconnect after 503 error

解決方法

自己寫重連的程式碼

import socketio
from threading import Timer

timer = None
address = "http://127.0.0.1:2027"
sio = socketio.Client(reconnection=False, logger=False, engineio_logger=False)
isConnected = False

def connectSocket():
    global timer
    try:
        sio.connect(address, transports='polling')
    except:
        if timer is not None:
            timer.cancel()
        timer = Timer(1.0, connectSocket)
        timer.start()

def close():
    global sio
    global timer
    global isConnected
    sio.disconnect()
    isConnected = False
    if timer is not None:
        timer.cancel()

@sio.event
def test():
    print('(test)'


def send(data):
    sio.emit('send', data)


@sio.event
def connect():
    global isConnected
    print('(connect)')


@sio.event
def disconnect():
    global timer
    global isConnected
    print('(disconnected)')
    sio.disconnect()
    isConnected = False
    if timer is not None:
        timer.cancel()
    timer = Timer(1.0, connectSocket)
    timer.start()
