RatchetCommands

RatchetCommands lets your application communicate messages to the Ratchet server instance.

Getting started

1. Requirements

This plugin depends on the following plugin and libraries and are pulled in by composer later on:

• Ratchet

2. Composer

Make sure you have composer installed and configured with the autoloader registering during bootstrap as described here. Make sure you have a composer.json and add the following to your required section.

composer require wyrihaximus/ratchet-commands 

3. Setup the plugin

Make sure you load RatchetCommands in your bootstrap and the Ratchet plugin is setup properly.

4. Building a command

Filename: Lib/MessageQueue/Command/BroadcastCommand.php

class BroadcastCommand extends RatchetMessageQueueCommand {

	public function serialize() {
		return serialize(array(
			'data' => $this->data,
		));
	}

	public function unserialize($commandString) {
		$commandString = unserialize($commandString);
		$this->setData($commandString['data']);
	}

	public function setData($data) {
		$this->data = $data;
	}

	public function getData() {
		return $this->data;
	}

	// Send a broadcast on the channel `channel` with the data sent with the command
	// (This runs in the Ratchet instance.)
	public function execute($eventSubject) {
		$topics = $eventSubject->getTopics();
		if (isset($topics['channel'])) {
			$topics['channel']->broadcast($this->getData());
		}

		return true;
	}

	// Handle the response
	// (This runs in the application.)
	public function response($response) {
		if ($response) {
			// Handle success
		} else {
			// Handle failure
		}
	}
}

Besure to App::uses the command in your bootstrap so the Ratchet instance knows where to load it from.

5. Sending the message

App::uses('TransportProxy', 'RatchetCommands.Lib/MessageQueue/Transports');
$command = new BroadcastCommand();
$command->setData([
	'time' => time(),
]);
TransportProxy::instance()->queueMessage($command);
