Hello

I have a problem that is really frustrating. Can anyone help me?

Here is the scenario: (See codesnippets further down)

I have declared one queue ”pp-queue” and is binding this queue to exchange ”weblager-exchange with binding key ”#.tiff.#” and to exchange ”pp-exchange” with binding key ”#.tif.#”. Both exchanges are declared as type ”topic”.

Then publishing 2 messages say ”wl message 1” and ”wl message 2” to exchange ”weblager-exchange” using routing key ”wl.tiff.tiff2pdf”
and publishing 2 messages say ”pp message 1” and ”pp message 2” to exchange ”pp-exchange” using routing key ”pp.tif.cmpt” the result as follows:

consume command of queue ”pp-queue” with binding to ”weblager-exchange” retrieves message ” wl message 1” and ” pp message 1” and
consume command of queue ”pp-queue” with binding to ”pp-exchange” retrieves message ” wl message 2” and ” pp message 2”.

Why does it not return the correct messages according to the binding keys?


All codesnippets are written in PHP.

Codesnippet - declaration of pp-queue, binding to weblager-exchange and consume - first call

Code:
$channel->basic_declare(
                      ’pp-queue’,
                      false,
                      true,
                      false,
                      false
);

$channel->queue_bind(
’pp-queue’,
                      ’weblager-exchange’,
                      ’#.tiff.#’,
                      false,
                      NULL,
                      NULL
);

$channel->basic_qos(
                      null,
                      1,
                      null
);

$channel->basic_consume(
                      ’pp-queue’,
                      ’wl’,
                      false
                      false
                      false
                      false
$settings->callback // callback
);
