BraincraftedMqBundle

BraincraftedMqBundle wraps BcMq into a nice bundle for Symfony2 to provide you with a PHP implementation of a Message Queue Sever.

By Florian Eckerstorfer.

Installation

The recommended way of installing BraincraftedMqBundle is through Composer.

#composer.json
{
    "require": {
        "braincrafted/mq-bundle": "dev-master"
    }
}

You also need to add it to your AppKernel.php.

// app/AppKernel.php
public function registerBundles()
{
    $bundles = array(
        // ...
        new Braincrafted\Bundle\MqBundle\BraincraftedMqBundle()
    );

    // ...

    return $bundles;
}

Usage

BraincraftedMqBundle uses services (instead of callbacks) to consume messages. You can configure those consumers in your config.yml.

app/config/config.yml

braincrafted_mq:
    consumers:
        write_file: acme_demo.consumer.write_file

Now you need to define the service acme_demo.consumer.write_file in your bundles service configuration. You have to write those consumers by yourself. An example is given below.

<?php
// src/Braincrafted/Bundle/MqDemoBundle/Consumer/WriteFileConsumer.php

namespace Braincrafted\Bundle\MqDemoBundle\Consumer;

class WriteFileConsumer
{
    private $filename;

    public function __construct($filename)
    {
        $this->filename = $filename;
    }

    public function consume($message)
    {
        file_put_contents($this->filename, $message."\n", FILE_APPEND);
    }
}

Please note, that in this case $message is a string but you can also send more complex messages, for example, arrays. Everything that can be encoded as JSON can be sent.

If your consumers are in place you can start the message queue server and send messages.

$ php app/console braincrafted:mq:server -p 4000

It is also possible to start the server in verbose mode by using the --verbose or -v option. If the verbose mode is activated, every bit of incoming data is echoed in the console.

The server will redirect every message that is sent to port 4000 to the consumers. Each message must be a JSON object and must contain exactly two values: type and message. Type is name name of the consumer (write_file in the example above) and message is a string or an array.

{
    "type": "write_file",
    "message": "Hello World!"
}

A complex message:

{
    "type": "write_file",
    "message": { "text": "Hello World!", "date": "2013-05-29" }
}

If you want to send the messages from your Symfony app you can use the producer provided by the bundle.

$producer = $container->get('braincrafted_mq.producer');
$producer->produce('write_file', 'Hello World!');

The message can also be an array:

$producer = $container->get('braincrafted_mq.producer');
$producer->produce('write_file', array('text' => 'Hello World!', 'time' => time());
