aio-pika

Wrapper for the PIKA for asyncio and humans. See examples and the tutorial in documentation.

If you are newcomer in the RabbitMQ let's start the adopted official RabbitMQ tutorial

Features

• Completely asynchronous API.
• Object oriented API.
• Auto-reconnects with complete state recovery with connect_robust (e.g. declared queues or exchanges, consuming state and bindings).
• Python 3.4+ compatible (include 3.6).

Installation

pip install aio-pika

Usage example

import asyncio
from aio_pika import connect_robust, Message


async def main(loop):
    connection = await connect_robust("amqp://guest:guest@127.0.0.1/", loop=loop)

    queue_name = "test_queue"
    routing_key = "test_queue"

    # Creating channel
    channel = await connection.channel()

    # Declaring exchange
    exchange = await channel.declare_exchange('direct', auto_delete=True)

    # Declaring queue
    queue = await channel.declare_queue(queue_name, auto_delete=True)

    # Binding queue
    await queue.bind(exchange, routing_key)

    await exchange.publish(
        Message(
            bytes('Hello', 'utf-8'),
            content_type='text/plain',
            headers={'foo': 'bar'}
        ),
        routing_key
    )

    # Receiving message
    incoming_message = await queue.get(timeout=5)

    # Confirm message
    incoming_message.ack()

    await queue.unbind(exchange, routing_key)
    await queue.delete()
    await connection.close()


if __name__ == "__main__":
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main(loop))

For contributors

You feel free to create pull request, but you should describe your cases and add some examples.

The changes should follow simple rules:

• When your changes breaks public API you must increase the major version.
• When your changes is safe for public API (e.g. added an argument with default value)
• You have to add test cases (see tests/ folder)
• You must add docstrings
• You feel free to add yourself to "thank's to" section
