Producer/Consumer Example

This example demonstrates using Producer/Consumer messaging with HTTP polling and HTTP long-polling channels. The application is a very simple chat client.

Example demo

The example is located in SVN within the examples/messaging directory

The example has scripts for serving the application via CherryPy, Twisted Web, and Tornado.

Start the server and open two browser windows to http://localhost:8000

Click the 'Subscribe' button to start receiving messages.

Click the 'Publish' button to send a message.

When a message is published, it should appear in both browser windows.

The default 'amf' url uses polling. Change the url to 'longPoll' to use long-polling.

If you change the url, you must un-subscribe and re-subscribe to start receiving messages from the new url.

CherryPy

Use CherryPy web framework and WSGI to serve the example with the following command:

python messaging/python/cp_server.py

Twisted

Use Twisted web framework to serve the example with the following command:

twistd -noy messaging/python/twisted_server.tac

Point your browser to http://localhost:8000/messaging.html.

Tornado

Use Facebook's Tornado web framework to serve the example with the following command:

python messaging/python/tornado_server.py

Point your browser to http://localhost:8000/static/messaging.html.
