rabbitpy 0.13.0

A pure python, thread-safe, minimalistic and pythonic RabbitMQ client library

rabbitpy - rabbitmq simplified

A pure python, thread-safe, minimalistic and pythonic BSD Licensed AMQP/RabbitMQ library that supports Python 2.6+ and Python 3.2+. rabbitpy aims to provide a simple and easy to use API for interfacing with RabbitMQ, minimizing the programming overhead often found in other libraries.

Installation

rabbitpy may be installed via the Python package index with the tool of your choice. I prefer pip:

pip install rabbitpy

But there’s always easy_install:

easy_install rabbitpy

rmqid Compatibility

rabbitpy is API compatible with rmqid.

Requirements

• pamqp - https://github.com/pika/pamqp

• requests - http://docs.python-requests.org/

Examples

Simple Publisher

The simple publisher is ideal for sending one off messages:

>>> rabbitpy.publish('amqp://guest:guest@localhost:5672/%2f',
                     exchange='test',
                     routing_key='example',
                     body='This is my test message')

If you want to add properties:

>>> rabbitpy.publish('amqp://guest:guest@localhost:5672/%2f',
                     exchange='test',
                     routing_key='example',
                     body='This is my test message',
                     properties={'content_type': 'text/plain'})

And publisher confirms:

>>> rabbitpy.publish('amqp://guest:guest@localhost:5672/%2f',
                     exchange='test',
                     routing_key='example',
                     body='This is my test message',
                     properties={'content_type': 'text/plain'},
                     confirm=True)
True
>>>

Simple Getter

>>> m = rabbitpy.get('amqp://guest:guest@localhost:5672/%2f', 'test')
>>> m.json()
{u'foo': u'bar'}

Simple Consumer

>>> for message in rabbitpy.consume('amqp://guest:guest@localhost:5672/%2f', 'example', no_ack=True):
...     message.pprint(properties=True)
...
Exchange: amq.topic
