A PHP client for the FBNS, built on top of ReactPHP. Includes generic RTI client implementation.

Requirements

You have to install the GMP extension to be able to run this code on x86 PHP builds.

Installation

composer require valga/fbns-react

Basic Usage

// Set up a Push client.
$loop = \React\EventLoop\Factory::create();
$auth = new \Fbns\Auth\DeviceAuth();
$device = new \Fbns\Device\DefaultDevice(USER_AGENT);
$network = new \Fbns\Network\Wifi();
$client = new \Fbns\Client($loop, $auth, $device, $network, $logger);

// Read saved credentials from the storage.
try {
    $auth->read($storage->get('fbns_auth'));
} catch (\Throwable $e) {
}

// Bind events.
$client
    ->on('connect', static function (string $jsonAuth) use ($client, $auth, $storage, $app) {
        // Update credentials and save them to the storage for future use.
        try {
            $auth->read($jsonAuth);
            $storage->set('fbns_auth', json_encode($auth));
        } catch (\Throwable $e) {
        }
        
        // Register the application.
        $client->register(PACKAGE_NAME, APPLICATION_ID)
            ->then(static function (\Fbns\Push\Registration $registration) use ($app) {
                $app->registerPushToken($registration->getToken());
            });
    })
    ->on('push', static function (\Fbns\Push\Notification $message) use ($app) {
        // Handle received notification payload.
        $app->handlePushNotification($message->getPayload());
    });

// Connect to the broker.
$client->connect(HOSTNAME, PORT);

// Run main loop.
$loop->run();

Advanced Usage

// Set up a proxy.
$connector = new \React\Socket\Connector($loop);
$proxy = new \Clue\React\HttpProxy('username:password@127.0.0.1:3128', $connector);

// Disable SSL verification.
$ssl = new \React\Socket\SecureConnector($proxy, $loop, ['verify_peer' => false, 'verify_peer_name' => false]);

// Enable logging to stdout.
$logger = new \Monolog\Logger('push');
$logger->pushHandler(new \Monolog\Handler\StreamHandler('php://stdout', \Monolog\Logger::INFO));

// Set up a Push client.
$client = new \Fbns\Client($loop, $auth, $device, $network, $logger, $connector);

// Persistence.
$client->on('disconnect', static function () {
    // Network connection has been closed. You can reestablish it if you want to.
});
$client->connect(HOSTNAME, PORT)
    ->otherwise(static function () {
        // Connection attempt was unsuccessful, retry with an exponential backoff.
    });
