[rabbitmq-discuss] python stomp examples

Thu Sep 11 09:58:19 BST 2008

Hi All

Rather late to the party, but I thought I'd let you know I've found  
out what the problem was with stomp.py. Two problems actually:

1.  the user/passcode headers weren't being issued with the connect  
(dumb omission on my part)

2.  the stomp protocol is a bit ambiguous about the use of spacing  
between header key and value.  For example:

      header: value
      header:value

Both forms are used in the stomp protocol examples.  My version of the  
client used a space -- it appears RabbitMQ doesn't like it.  I've  
removed the space, and along with the prior fix it appears to work  
properly now (the latest version is on my site).

Just for your info.

Kind regards
Jason
