Quick start¶
Stomp.py is a Python library providing access to a message broker using the STOMP protocol - either programmatically or using a command line client.
Installation¶
Stomp is available on PyPi. Install it in a new environment using virtualenv and pip:
$ virtualenv -p python3 teststomp
$ . teststomp/bin/activate
(teststomp) $ pip install stomp.py
(teststomp) $ stomp --version
Stomp.py API¶
A simple example of creating a listener, sending and receiving a message using localhost with the default port (61613), can be seen here:
import time
import sys
import stomp
class MyListener(stomp.ConnectionListener):
def on_error(self, frame):
print('received an error "%s"' % frame.body)
def on_message(self, frame):
print('received a message "%s"' % frame.body)
conn = stomp.Connection()
conn.set_listener('', MyListener())
conn.connect('admin', 'password', wait=True)
conn.subscribe(destination='/queue/test', id=1, ack='auto')
conn.send(body=' '.join(sys.argv[1:]), destination='/queue/test')
time.sleep(2)
conn.disconnect()
Assuming this was saved to stomptest.py, the code can be executed as follows:
$ python stomptest.py This is a test
received a message "This is a test"
Command-line Client¶
Assuming stomp.py is installed (using pip) in the site-packages directory (e.g. lib/python3.3/site-packages), hereby referred to as ${SITEPACKAGES}, then you can run the command line client as follows:
$ stomp -H localhost -P 61613
After a successful connection, you can type commands such as:
subscribe /queue/test
send /queue/test hello world
If you need to pass a username and password to the client:
$ stomp -H localhost -P 61613 -U admin -W password
Type help for more information once you’re running the command-line interface, or run the following to see the list of startup arguments:
$ stomp --help
