[rabbitmq-discuss] New Open source AMQP implementation, problems with integrating using different langauges

Tue Feb 8 02:08:24 GMT 2011

I have found the solution to my problem.
I set found out that the flags were the content-type and content-encoding. When 
I set these properties in the python code then I could consumer the message on 
the PHP side without an exception being thrown.

Hi there.
I have a python program that talks to a rabbit MQ server using its own library. 
On my end I am running Robin's AMQP PHP 
library,https://github.com/BraveSirRobin/amqphp to connect to the Rabbit MQ 
server. I can submit a message to the queue and the python side can read it, but 

if the python side submits a message to the queue and the PHP side tries to 
consume it I am getting an Exception thrown from inside amqp.wire.php: 
"Unexpected message property flags".
This is happening because the strlen($binFlags) is evaluating to 0 in this case. 

If I run it using PHP submitted messages then it correctly evaliuates to a 
length of 16.
The binary flags is 1100000000000000(49152) for a PHP suibmitted message read 
off the queue, but it is 0 for the message read off the queue that was put there 

by python.
What is causing this? Also what do these flags really represent.
As a temporary work around I have managed to get the code to read the message by 

simply commenting out these three lines of code that check this binary flags 
length.
Thanks.
