RabbitMq Service Provider for Silex

About

This Silex service provider incorporates the awesome RabbitMqBundle into your Silex Application. Installing this bundle created by Alvaro Videla you can use RabbitMQ messaging features in your application, using the php-amqplib library.

After installing this service provider, sending messages from a controller would be something like

$app->post('/message', function(Request $request) use ($app){
    $producer = $app['rabbit.producer']['my_exchange_name'];
    $producer->publish('Some message');

    return new Response($msg_body);
});

Later when you want to consume 50 messages out of the queue names 'my_queue', you just run on the CLI:

$ ./app/console rabbitmq:consumer -m 50 my_queue

To learn what you can do with the bundle, please read the bundle's README.

Installation

Require the library with Composer:

$ composer require fiunchinho/rabbitmq-service-provider

Then, to activate the service, register the service provider after creating your Silex Application:

use Silex\Application;
use fiunchinho\Silex\Provider\RabbitServiceProvider;

$app = new Application();
$app->register(new RabbitServiceProvider());

Start sending messages ;)

Usage

In the README file from the Symfony bundle you can see all the available options. For example, to configure our service with two different connections and a couple of producers, and one consumer, we will pass the following configuration:

$app->register(new RabbitServiceProvider(), [
    'rabbit.connections' => [
        'default' => [
            'host'      => 'localhost',
            'port'      => 5672,
            'user'      => 'guest',
            'password'  => 'guest',
            'vhost'     => '/'
        ],
        'another' => [
            'host'      => 'another_host',
            'port'      => 5672,
            'user'      => 'guest',
            'password'  => 'guest',
            'vhost'     => '/'
        ]
    ],
    'rabbit.producers' => [
        'first_producer' => [
            'connection'        => 'another',
            'exchange_options'  => ['name' => 'a_exchange', 'type' => 'topic']
        ],
        'second_producer' => [
            'connection'        => 'default',
            'exchange_options'  => ['name' => 'a_exchange', 'type' => 'topic']
        ],
    ],
    'rabbit.consumers' => [
        'a_consumer' => [
            'connection'        => 'default',
            'exchange_options'  => ['name' => 'a_exchange','type' => 'topic'],
            'queue_options'     => ['name' => 'a_queue', 'routing_keys' => ['foo.#']],
            'callback'          => 'your_consumer_service'
        ]
    ]
]);

Keep in mind that the callback that you choose in the consumer needs to be a service that has been registered in the Pimple container. Consumer services implement the ConsumerInterface, which has a execute() public method.

Consumers in the command line

We recommend you to use the Consumer command to consume messages from the queues. To use this command, just create the executable for console (as in any console applicaiton)

#!/usr/bin/env php
<?php

require_once 'vendor/autoload.php';

use Silex\Application;
use fiunchinho\Silex\Provider\RabbitServiceProvider;
use fiunchinho\Silex\Command\Consumer;
use Knp\Provider\ConsoleServiceProvider;

$app = new Application();
require __DIR__.'/config/dev.php';
$app->register(new RabbitServiceProvider(), array(
    'rabbit.consumers' => [
        'my_consumer' => [
            'connection'        => 'default',
            'exchange_options'  => ['name' => 'my_exchange_name','type' => 'topic'],
            'queue_options'     => ['name' => 'a_queue', 'routing_keys' => ['foo.#']],
            'callback'          => 'my_service'
        ]
    ]
));
$app->register(new ConsoleServiceProvider(), array(
    'console.name'              => 'MyApplication',
    'console.version'           => '1.0.0',
    'console.project_directory' => __DIR__
));


$application = $app['console'];
$application->add(new Consumer());
$application->run();

We rely on the Knp\Provider\ConsoleServiceProvider to make things easier, so you have to register it too. You can create new commands by inheriting from the example Consumer, and adding them as the example above.
