A pika consumer class which may be used to create rabbitmq queue consumers

Project description

pika-consumer
=============
Because there isn't one distributed with pika

An easy to use pika consumer based on the example pika asynchronous consumer. It probably works with versions of python besides 3.6, but it hasn't been tested.

Use
---

With this module installed, simply extend the *pika_consumer.Consumer* class and override its *on_message* method. The *acknowledge_message* method should be called in the overriden method:


.. code:: python
from pika_consumer import Consumer

def consume_message(body):
# do stuff with the message body

class ExampleConsumer(Consumer):

def on_message(self, channel, basic_deliver, properties, body):
consume_message(body)
self.acknowledge_message(basic_deliver.delivery_tag)

Then set the consumer consuming:

.. code:: python
amqp_url = 'amqp://user:name@rabbit_host:5672/%2F'
queue = 'your_queue'
routing_key = 'your_routing_key'
exchange = 'your_exchange'
consumer = ExampleConsumer(amqp_url, queue, routing_key, exchange)
consumer.consume()

Example
-------

Running `vagrant up` will create a VM running rabbitmq and python 3.6 running an example consumer which will populate a file in the repo, *example.log* upon running

.. code:: sh
vagrant ssh -c '/usr/local/lib/pyenv/versions/3.6.0/bin/python /vagrant/bin/example_publisher.py'
