class
bhiveapi.websocket.
HiveWebsocket
(urls, user='', password='', only_block_id=False, on_block=None, keep_alive=25, num_retries=-1, timeout=60, *args, **kwargs)¶ Bases:
events.events.Events
Create a websocket connection and request push notifications
- Parameters
urls (str) – Either a single Websocket URL, or a list of URLs
user (str) – Username for Authentication
password (str) – Password for Authentication
keep_alive (int) – seconds between a ping to the backend (defaults to 25seconds)
After instanciating this class, you can add event slots for:
on_block
which will be called accordingly with the notification message received from the Hive node:
ws = HiveWebsocket( "wss://gtg.steem.house:8090", ) ws.on_block += print ws.run_forever()
-

login,
register to the database api, and
subscribe to the objects defined if there is a callback/slot available for callbacks
