Symfony2 and RabbitMqBundle. Can't publish a message - symfony

Question

I am trying to use syfmony2 framework with RabbitMqBundle from here
I am sure that my rabbitmq server is up and running and I am doing the configuration and publishers code accordingly to the docs delivered on github. Unfortunately I can`t add any message to the queue.
I am sure that my rabbitmq server is up and running. I have queue named accordingly to the symfony configuration file.
Have anyone got any clue what is wrong?
Thanks in advance for any suggestions.

Answer 1

well... try this simple example
# app/config.yml
old_sound_rabbit_mq:
connections: %rabbitmq_connections%
producers: %rabbitmq_producers%
consumers: %rabbitmq_consumers%
parameters:
# connection parameters
rabbitmq_connections:
default: { host: 'localhost', port: 5672, user: 'guest', password: 'guest', vhost: '/' }
# define producers
rabbitmq_producers:
sample:
connection: default
exchange_options: {name: 'exchange_name', type: direct, auto_delete: false, durable: true}
# define consumers
rabbitmq_consumers:
sample:
connection: default
exchange_options: {name: 'exchange_name', type: direct, auto_delete: false, durable: true}
queue_options: {name: 'sample', auto_delete: false}
callback: rabbitmq.callback.service
then you should define your callback service. feel free to put it in app/config.yml
services:
rabbitmq.callback.service:
class: RabbitMQ\Callback\Service
and yes. you should write this callback service. here is simple implementation. should be enough for understanding and check is it works for you.
namespace RabbitMQ\Callback;
use OldSound\RabbitMqBundle\RabbitMq\ConsumerInterface;
use PhpAmqpLib\Channel\AMQPChannel;
use PhpAmqpLib\Message\AMQPMessage;
class Service implements ConsumerInterface
{
public function execute(AMQPMessage $msg)
{
var_dump(unserialize($msg->body));
}
}
then you should start rabbitmq server, run consumer and check was new exchange and queue added.
to run test consumer you should run
app/console rabbitmq:consumer sample --route="sample"
in your controller (where you want to send message to rabbitMQ put next code
# get producer service
$producer = $this->get('old_sound_rabbit_mq.sample_producer');
# publish message
$producer->publish(serialize(array('foo'=>'bar','_FOO'=>'_BAR')), 'sample');
Hope it's more or less clear and will help you with rabbitmq.
PS: it's easier to debug if you have rabbitmq management plugin. if you have no, use console commands like rabbitmqctl to check queues/exchanges/consumers and so on...
and also would be nice to see your configuration for producers/consumers. callback services code as well.

Answer 2

I also had some issue to send messages with this bundle, i recommend you to try SonataNotificationBundle instead.
You can also install the RabbitMq management plugin to see the queued messages.
