when ues async_mode='eventlet' client can't get the message from server.

[2651084156]

i use code like this to send message

code

def ioioio(acc):
a = 222
v =111
'''miaoshu'''
time.sleep(1)
'''def client_1():
print('**************************')
emit('server_response',
{'data': pachong.idnumget['data'], 'data2': pachong.idnumget['data2'], 'data3': pachong.idnumget[acc]},
broadcast=True)'''

#print(pachong.idnumget[pachong.idnumget[acc]])
#print(pachong.idnumget[pachong.idnumget[acc] + 'L'])
#print('AAAAA')
socketio.emit('server_response',{'data': str(listas), 'data2':a , 'data3': a},broadcast=True,namespace=name_space)
socketio.emit('server_response',{'data': str(listas1), 'data2': v, 'data3': v}, broadcast=True, namespace=name_space1)

def getlong():
time.sleep(4)
while True:

   # print('+++++++++++++++')
    #print('AAAA')
    ioioio('AAA')

if name == 'main':
t11 = threading.Thread(target=getlong, args=())
print('111111++++++++++++++++++')
t11.setDaemon(True)
# socketio.start_background_task(target=getlong,kwargs=())
t11.start()
socketio.run(app, host='0.0.0.0', port=5000,debug=True )

but when i use async_mode='threading') it work
but when use it it can not use websocket
and i want ues websocket
so what can i to slove it

Are you reading the documentation?

If you stay with threading, you can install simple-websocket to add WebSocket support.
If you prefer eventlet, then you have to use eventlet's own concurrency functions, or else monkey patch the standard library.

Once again, you need to read the documentation to find the correct way to do things: https://flask-socketio.readthedocs.io/en/latest/api.html#flask_socketio.SocketIO.start_background_task

This function does not have an args argument, it uses standard positional and keyword arguments.

will when i use kwargs is still give me a error.Is any thing wrong i do?

You are doing it wrong, there are no args or kwargs arguments. See https://realpython.com/python-kwargs-and-args/ if you don't know how these arguments work.
