ubuntu@dlp:~$
vi send_msg.py import pika credentials = pika.PlainCredentials( 'serverworld', 'password' ) connection = pika.BlockingConnection( pika.ConnectionParameters( 'localhost', 5672, '/my_vhost', credentials ) ) channel = connection.channel() channel.queue_declare(queue='Hello_World') channel.basic_publish( exchange='', routing_key='Hello_World', body='Hello RabbitMQ World!' ) print(" [x] Sent 'Hello_World'") connection.close() python3 send_msg.py [x] Sent 'Hello_World' |
[3] | This is an example of receiving message on Python. |
ubuntu@node01:~$
vi receive_msg.py import signal import pika signal.signal(signal.SIGPIPE, signal.SIG_DFL) signal.signal(signal.SIGINT, signal.SIG_DFL) credentials = pika.PlainCredentials( 'serverworld', 'password' ) connection = pika.BlockingConnection( pika.ConnectionParameters( '10.0.0.30', 5672, '/my_vhost', credentials ) ) channel = connection.channel() channel.queue_declare(queue='Hello_World') def callback(ch, method, properties, body): print(" [x] Received %r" % body ) channel.basic_consume('Hello_World', callback, auto_ack=True) print(' [*] Waiting for messages. To exit press CTRL+C') channel.start_consuming() python3 receive_msg.py [*] Waiting for messages. To exit press CTRL+C [x] Received b'Hello RabbitMQ World!' |
