I'm trying to implement websockets in Symfony2,
I found this http://socketo.me/ which seems pretty good.
I try it out of Symfony and it works, this was just a simple call using telnet. But I don't know how to integrate this in Symfony.
I think I have to create a service but I don't know realy which kind of service and how to call it from the client
Thanks for your help.
First you should create a service. If you want to inject your entity manager and other dependencies, do it there.
In src/MyApp/MyBundle/Resources/config/services.yml:
services:
chat:
class: MyApp\MyBundle\Chat
arguments:
- @doctrine.orm.default_entity_manager
And in src/MyApp/MyBundle/Chat.php:
class Chat implements MessageComponentInterface {
/**
* @var \Doctrine\ORM\EntityManager
*/
protected $em;
/**
* Constructor
*
* @param \Doctrine\ORM\EntityManager $em
*/
public function __construct($em)
{
$this->em = $em;
}
// onOpen, onMessage, onClose, onError ...
Next, make a console command to run the server.
In src/MyApp/MyBundle/Command/ServerCommand.php
use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Ratchet\Server\IoServer;
class ServerCommand extends ContainerAwareCommand
{
protected function configure()
{
$this
->setName('chat:server')
->setDescription('Start the Chat server');
}
protected function execute(InputInterface $input, OutputInterface $output)
{
$chat = $this->getContainer()->get('chat');
$server = IoServer::factory($chat, 8080);
$server->run();
}
}
Now you have a Chat class with dependency injections, and you can run the server as a console command. Hope this helps!
