Andreas Waider commented on PROTON-2469:
----------------------------------------
Thank you so much for your fast and excellent feedback! This solved my issue.
I'm just wondering, what went wrong when I tried to subscribe to "amq.topic"
and print all messages. But if it work it works :)
> How to use proton-python properly to receive messages
> -----------------------------------------------------
>
> Key: PROTON-2469
> URL: https://issues.apache.org/jira/browse/PROTON-2469
> Project: Qpid Proton
> Issue Type: Bug
> Components: python-binding
> Reporter: Andreas Waider
> Priority: Major
>
> My configuration:
> Running qpidd on host: 192.168.80.81 with following exchanges (`qpid-config
> exchanges`):
> ```
> Type Exchange Name Attributes
> ==================================================
> direct --replicate=none
> direct amq.direct --durable --replicate=none
> fanout amq.fanout --durable --replicate=none
> headers amq.match --durable --replicate=none
> topic amq.topic --durable --replicate=none
> direct qmf.default.direct --replicate=none
> topic qmf.default.topic --replicate=none
> topic qpid.management --replicate=none
> ```
> I have multiple producers publishing to the topics like
> `amq.topic/com.product.sample1`, `amq.topic/com.product.sample2`, you get the
> pattern.
> I can receive all messages from the producers by running `qpid-receive -b
> 192.168.80.81 -a amq.topic/com.product.sample1 -f` on the commandline.
> But when it comes to implementing this in Python using the
> [python-qpid-proton](https://pypi.org/project/python-qpid-proton/) library
> (version 0.35.0) it wont work as needed. This is my python file to receive
> messages on a specific topic:
> ```
> from proton.handlers import MessagingHandler
> from proton.reactor import Container
> broker_url = "192.168.80.81:5672"
> topic = "amq.topic/com.product.sample"
> class Client(MessagingHandler):
> def __init__(self, broker_url, topic):
> super(Client, self).__init__()
> self.broker_url = broker_url
> self.topic = topic
> def on_start(self, event):
> conn = event.container.connect(self.broker_url)
> self.receiver = event.container.create_receiver(
> conn, self.topic, dynamic=True)
> def on_message(self, event):
> print(event.message.body)
> Container(Client(broker_url, topic)).run()
> ```
> Can anyone help me and point me to where my mistake is? Help is much
> appreciated!
