on_message
0{"sid":"NjIwMWNhZGM0NTc3NA==","upgrades":[],"pingInterval":25000,"pingTimeout":60000}
on_message
40
on_message
42["message","connected"]
### closed ###

Process finished with exit code 0

My simple python code:

import websocket
import _thread
import time

def on_message(ws, message):
    print('on_message')
    print(message)

def on_error(ws, error):
    print('error')
    print(error)

def on_close(ws, close_status_code, close_msg):
    print("### closed ###")

def on_open(ws):
    def run(*args):
        for i in range(3):
            time.sleep(1)
            ws.send('welcome3')

        time.sleep(1)
        ws.close()
        print("thread terminating...")
    _thread.start_new_thread(run, ())

if __name__ == "__main__":

    ws = websocket.WebSocketApp("ws://localhost:1215/",
                              on_open=on_open,
                              on_message=on_message,
                              on_error=on_error,
                              on_close=on_close,
                            )

    ws.run_forever()
