aiormq is a pure python AMQP client library.

Status

Production/Stable

Features

Connecting by URL

amqp example: amqp://user:password@server.host/vhost

secure amqp example: amqps://user:password@server.host/vhost?cafile=ca.pem&keyfile=key.pem&certfile=cert.pem&no_verify_ssl=0

Buffered queue for received frames
Only PLAIN auth mechanism support
Publisher confirms support
Transactions support
Channel based asynchronous locks

Note

AMQP 0.9.1 requires serialize sending for some frame types on the channel. e.g. Content body must be following after content header. But frames might be sent asynchronously on another channels.
Tracking unroutable messages (Use connection.channel(on_return_raises=False) for disabling)
Full SSL/TLS support with url query parameters:
- cafile= - string contains path to ca certificate file
- capath= - string contains path to ca certificates
- cadata= - base64 encoded ca certificate data
- keyfile= - string contains path to key file
- certfile= - string contains path to certificate file
- no_verify_ssl - boolean disables certificates validation
Python type hints
Uses pamqp as an AMQP 0.9.1 frame encoder/decoder

Introduction

Simple consumer

import asyncio

async def on_message(message):
    """
    on_message doesn't necessarily have to be defined as async.
    Here it is to show that it's possible.
    """

    print("Before sleep!")
