pythin and pika and recovery (while)

recovery.md

Blocking connection can be recovered in exception handling style (similar to php client). For example:

while True:
    connection = pika.BlockingConnection(parameters)

    channel = connection.channel()
    channel.basic_consume(on_message, 'queue')

    try:
        channel.start_consuming()
    except pika.exceptions.ConnectionClosed:
        LOGGER.info('Connection closed. Recovering')
        continue
    except KeyboardInterrupt:
        channel.stop_consuming()

    connection.close()
    break
    ```
