stomp.py

"stomp.py" is a Python client library for accessing messaging servers (such as ActiveMQ Classic, ActiveMQ Artemis or RabbitMQ) using the STOMP protocol (STOMP v1.0, STOMP v1.1 and STOMP v1.2). It can also be run as a standalone, command-line client for testing. NOTE: Stomp.py has officially ended support for Python2.x. See python3statement.org for more information.

Quick Start

You can connect to a message broker running on the local machine, and send a message using the following example.

import stomp

conn = stomp.Connection()
conn.connect('admin', 'password', wait=True)
conn.send(body=' '.join(sys.argv[1:]), destination='/queue/test')
conn.disconnect()

Documentation and Resources

• Main documentation
• API documentation (see stomp.github.io for details on the STOMP protocol itself)
• A basic example of using stomp.py with a message listener can be found in the quick start section of the main documentation
• Description of the command-line interface
• Travis for continuous integration builds
• Current test coverage report
• PyPi stomp.py page

The current version of stomp.py supports:

• Python 3.x (Python2 support ended as of Jan 2020)
• STOMP version 1.0, 1.1 and 1.2

There is also legacy 3.1.7 version using the old 3-series code (see 3.1.7 on PyPi and 3.1.7 on GitHub). This is no longer supported, but (at least as of 2018) there were still a couple of reports of this version still being used in the wild.

Note: stomp.py now follows semantic versioning:

• MAJOR version for incompatible API changes,
• MINOR version for functionality added in a backwards compatible manner, and
• PATCH version for backwards compatible bug fixes.

Testing

stomp.py has been perfunctorily tested on:

• Pivotal RabbitMQ (test_rabbitmq.py)
• Apache ActiveMQ Classic (test_activemq.py)
• Apache ActiveMQ Artemis (test_artemis.py)
• stompserver (test_stompserver.py)

For testing locally, you'll need to install docker (or podman). Once installed:

1. Install dependencies:

   poetry install

2. Create the docker (or podman) image:

   make docker-image (or make podman-image)

3. Run the container:

   make run-docker (or make run-podman)

4. Run stomp.py unit tests:

   make test

5. Cleanup the container afterwards if you don't need it any more:

   make remove-docker (or make remove-podman)

If you want to connect to the test services locally (other than from the included tests), you'll want to add test domain names to your hosts file like so:

172.17.0.2 my.example.com

172.17.0.2 my.example.org

172.17.0.2 my.example.net

If you're using podman and you want to access services via their private IP addresses, you'll want to run your commands with:

podman unshare --rootless-netns <command>

so that <command> has access to the private container network. Service ports are also exposed to the host and can be accessed directly.
