Plain Sqs

A custom SQS connector for Laravel (or Lumen) that supports custom format JSON payloads. Out of the box, Laravel expects SQS messages to be generated in specific format - format that includes job handler class and a serialized job.

But in certain cases you may want to parse messages from third party applications, custom JSON messages and so on.

Dependencies

• PHP >= 5.5
• Laravel (or Lumen) >= 5.2

Installation via Composer

To install simply run:

composer require dusterio/laravel-plain-sqs

Or add it to composer.json manually:

{
    "require": {
        "dusterio/laravel-plain-sqs": "~0.1"
    }
}

Usage in Laravel 5

// Add in your config/app.php

'providers' => [
    '...',
    'Dusterio\PlainSqs\Integrations\LaravelServiceProvider',
];

Usage in Lumen 5

// Add in your bootstrap/app.php
$app->loadComponent('queue', 'Dusterio\PlainSqs\Integrations\LumenServiceProvider');

Configuration

// Generate standard config file (Laravel only)
php artisan vendor:publish

// In Lumen, create it manually (see example below) and load it in bootstrap/app.php
$app->configure('sqs-plain');

Edit config/sqs-plain.php to suit your needs. This config matches SQS queues with handler classes.

return [
    'handlers' => [
        'base-integrations-updates' => App\Jobs\HandlerJob::class,
    ],

    'default-handler' => App\Jobs\HandlerJob::class
];

If queue is not found in 'handlers' array, SQS payload is passed to default handler.

Add sqs-plain connection to your config/queue.php, eg:

        ...
        'sqs-plain' => [
            'driver' => 'sqs-plain',
            'key'    => env('AWS_KEY', ''),
            'secret' => env('AWS_SECRET', ''),
            'prefix' => 'https://sqs.ap-southeast-2.amazonaws.com/123123/',
            'queue'  => 'important-music-updates',
            'region' => 'ap-southeast-2',
        ],
        ...

In your .env file, choose sqs-plain as your new default queue driver:

QUEUE_DRIVER=sqs-plain

Dispatching to SQS

If you plan to push plain messages from Laravel or Lumen, you can rely on DispatcherJob:

use Dusterio\PlainSqs\Jobs\DispatcherJob;

class ExampleController extends Controller
{
    public function index()
    {
        // Create a PHP object
        $object = [
            'music' => 'M.I.A. - Bad girls',
            'time' => time()
        ];

        // Pass it to dispatcher job
        $job = new DispatcherJob($object);

        // Dispatch the job as you normally would
        // By default, your data will be encapsulated in 'data' and 'job' field will be added
        $this->dispatch($job);

        // If you wish to submit a true plain JSON, add setPlain()
        $this->dispatch($job->setPlain());
    }
}

This will push the following JSON object to SQS:

{"job":"App\\Jobs\\[email protected]","data":{"music":"M.I.A. - Bad girls","time":1462511642}}

'job' field is not used, actually. It's just kept for compatibility sake.

Receiving from SQS

If a third-party application is creating custom-format JSON messages, just add a handler in the config file and implement a handler class as follows:

use Illuminate\Contracts\Queue\Job as LaravelJob;

class HandlerJob extends Job
{
    protected $data;

    /**
     * @param LaravelJob $job
     * @param array $data
     */
    public function handle(LaravelJob $job, array $data)
    {
        // This is incoming JSON payload, already decoded to an array
        var_dump($data);

        // Raw JSON payload from SQS, if necessary
        var_dump($job->getRawBody());
    }
}
