ept.notify('LOGIN_EVENT', {'user_id': 4321})

Quick Event Subscription Example

import time
from gces import (
    EventSubscriber
)

def example_run_subscriber_function(data):
    print("Data Received: {}".format(data))


TOPIC_NAME = 'gces'
SUBSCRIBER_NAME = 'gces_example'


es = EventSubscriber(TOPIC_NAME, SUBSCRIBER_NAME)
es.register_fsub('EXAMPLE_RUN_FUNCTION_PROCCESS' example_run_subscriber_function)
es.start()

if __name__ == '__main__':
    try:
        while True:
            time.sleep(200)
    except KeyboardInterrupt:
        print('Bye!!!!')
