RabbitMQ : Use on Python
2016/09/03 |
|
This is an example to use RabbitMQ on Python.
|
|
| [1] | Install AMQP client library. |
|
# install from EPEL [root@dlp ~]# yum --enablerepo=epel -y install python2-pika
|
| [2] | This is an example of sending message on Python. For example, connect with RabbitMQ user "serverworld", virtualhost "my_vhost". |
|
[cent@dlp ~]$
vi send_msg.py #!/usr/bin/env python
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()
python send_msg.py [x] Sent 'Hello_World' |
| [3] | This is an example of receiving message on Python. |
|
[cent@node01 ~]$
vi receive_msg.py #!/usr/bin/env python
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(
'dlp.srv.world',
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(callback,
queue='Hello_World',
no_ack=True)
print(' [*] Waiting for messages. To exit press CTRL+C')
channel.start_consuming()
python receive_msg.py [*] Waiting for messages. To exit press CTRL+C [x] Received 'Hello RabbitMQ World!' |
