Flask executes the command and returns

1. At present, I have made a web version of the command execution using falsk-socketio, but it is found that it cannot be line-by-line

def shell(cmd, kwargs):
    print(">>>>>>>>> :%s" % cmd)
    program_name = kwargs.get("program_name")
    socketio_event = kwargs.get("socketio_event")
    socketio_sid = kwargs.get("socketio_sid")
    try:
        p = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
        print(">>>>>>>>> : %s : %s ID:%s " % (socketio_sid, program_name, str(p.pid)))

        while p.poll() is None:
            res = p.stdout.readline()
            print(res)
            emit(socketio_event, str(res))

        for i in p.stdout.readlines():
            emit(socketio_event, str(i))
    except Exception as e:
        debug(e)
        return -1
    else:
        return 0
