ratchet/pawl
package withcomposer
:
composer require cboden/ratchet
- Create a
WebsocketServer
class inapp/Websockets
and extend theRatchet\MessageComponentInterface
class:
<?php
namespace App\Websockets;
use Ratchet\MessageComponentInterface;
class WebsocketServer implements MessageComponentInterface
{
// ...
}
- Implement the
onOpen
,onMessage
,onClose
, andonError
methods in theWebsocketServer
class:
public function onOpen(ConnectionInterface $conn)
{
// ...
}
public function onMessage(ConnectionInterface $from, $msg)
{
// ...
}
public function onClose(ConnectionInterface $conn)
{
// ...
}
public function onError(ConnectionInterface $conn, \Exception $e)
{
// ...
}
- Create a route in
routes/websockets.php
to handle the websocket connection:
<?php
use App\Websockets\WebsocketServer;
use Ratchet\Http\HttpServer;
use Ratchet\Server\IoServer;
use Ratchet\WebSocket\WsServer;
$server = IoServer::factory(
new HttpServer(
new WsServer(
new WebsocketServer()
)
),
8080
);
$server->run();
- Start the websocket server in the terminal:
php artisan websockets:serve
- Use JavaScript to connect to the websocket server:
const socket = new WebSocket('ws://localhost:8080');
socket.onopen = function(e) {
console.log('Connection established');
};
socket.onmessage = function(e) {
console.log(e.data);
};
socket.onclose = function(e) {
console.log('Connection closed');
};
- Finally, open a browser and navigate to
http://localhost:8080
to establish the websocket connection.
