Implement message push based on Hyperf + RabbitMQ + WebSocket

A simple large-screen message push based on Hyperf WebSocket RabbitMQ.

Idea

Use the WebSocket protocol to maintain a stateful long connection between the client and the server, and

save the client ID of the link. Subscribing to messages published by a publisher broadcasts messages against a saved client id.

WebSocket service

composer require hyperf/websocket-server

Configuration file [config/autoload/server.php]

 SWOOLE_PROCESS, 'servers' => [ [ 'name' => 'http', 'type' => Server::SERVER_HTTP, 'host' => '0.0.0.0', 'port' => 11111, 'sock_type' => SWOOLE_SOCK_TCP, 'callbacks' => [ SwooleEvent::ON_REQUEST => [Hyperf\HttpServer\Server::class, 'onRequest'], ], ], [ 'name' => 'ws', 'type' => Server::SERVER_WEBSOCKET, 'host' => '0.0.0.0', 'port' => 12222, 'sock_type' => SWOOLE_SOCK_TCP, 'callbacks' => [ SwooleEvent::ON_HAND_SHAKE => [Hyperf\WebSocketServer\Server::class, 'onHandShake'], SwooleEvent::ON_MESSAGE => [Hyperf\WebSocketServer\Server::class, 'onMessage'], SwooleEvent::ON_CLOSE => [Hyperf\WebSocketServer\Server::class, 'onClose'], ], ], ],

WebSocket server-side code example

container->get(\Redis::class); //获取所有的客户端id $fdList = $redis->sMembers('websocket_sjd_1'); //如果当前客户端在客户端集合中,就刷新 if (in_array($frame->fd, $fdList)) { $redis->sAdd('websocket_sjd_1', $frame->fd); $redis->expire('websocket_sjd_1', 7200); } $server->push($frame->fd, 'Recv: ' . $frame->data); } /** * 客户端失去链接 * @param Server $server * @param int $fd * @param int $reactorId */ public function onClose(Server $server, int $fd, int $reactorId): void { //删掉客户端id $redis = $this->container->get(\Redis::class); //移除集合中指定的value $redis->sRem('websocket_sjd_1', $fd); var_dump('closed'); } /** * 客户端链接 * @param WebSocketServer $server * @param Request $request */ public function onOpen(WebSocketServer $server, Request $request): void { //保存客户端id $redis = $this->container->get(\Redis::class); $res1 = $redis->sAdd('websocket_sjd_1', $request->fd); var_dump($res1); $res = $redis->expire('websocket_sjd_1', 7200); var_dump($res); $server->push($request->fd, 'Opened'); } }

WebSocket front-end code

function WebSocketTest() { if ("WebSocket" in window) { console.log("您的浏览器支持 WebSocket!"); var num = 0 // 打开一个 web socket var ws = new WebSocket("ws://127.0.0.1:12222"); ws.onopen = function () { // Web Socket 已连接上，使用 send() 方法发送数据 //alert("数据发送中..."); //ws.send("发送数据"); }; window.setInterval(function () { //每隔5秒钟发送一次心跳，避免websocket连接因超时而自动断开 var ping = {"type": "ping"}; ws.send(JSON.stringify(ping)); }, 5000); ws.onmessage = function (evt) { var d = JSON.parse(evt.data); console.log(d); if (d.code == 300) { $(".address").text(d.address) } if (d.code == 200) { var v = d.data console.log(v); num++ var str = `
 
${v.recordOutTime}
 
${v.userOutName}
 
${v.userOutNum}
 
${v.doorOutName}
 
` $(".tableHead").after(str) if (num > 7) { num-- $(".table .item:nth-last-child(1)").remove() } } }; ws.error = function (e) { console.log(e) alert(e) } ws.onclose = function () { // 关闭 websocket alert("连接已关闭..."); }; } else { alert("您的浏览器不支持 WebSocket!"); } }

AMQP component

composer require hyperf/amqp

Configuration file [config/autoload/amqp.php]

 [ 'host' => 'localhost', 'port' => 5672, 'user' => 'guest', 'password' => 'guest', 'vhost' => '/', 'pool' => [ 'min_connections' => 1, 'max_connections' => 10, 'connect_timeout' => 10.0, 'wait_timeout' => 3.0, 'heartbeat' => -1, ], 'params' => [ 'insist' => false, 'login_method' => 'AMQPLAIN', 'login_response' => null, 'locale' => 'en_US', 'connection_timeout' => 3.0, 'read_write_timeout' => 6.0, 'context' => null, 'keepalive' => false, 'heartbeat' => 3, ], ], ];

MQ consumer code

container->get(\Redis::class); $fdList=$redis->sMembers('websocket_sjd_1'); $server=$this->container->get(ServerFactory::class)->getServer()->getServer(); foreach($fdList as $key=>$v){ if(!empty($v)){ $server->push((int)$v, $data); } } return Result::ACK; } }

Controller code

/** * test * @return array */ public function test() { $data = array( 'code' => 200, 'data' => [ 'userOutName' => 'ccflow', 'userOutNum' => '9999', 'recordOutTime' => date("Y-m-d H:i:s", time()), 'doorOutName' => '教师公寓', ] ); $data = \GuzzleHttp\json_encode($data); $message = new DemoProducer($data); $producer = ApplicationContext::getContainer()->get(Producer::class); $result = $producer->produce($message); var_dump($result); $user = $this->request->input('user', 'Hyperf'); $method = $this->request->getMethod(); return [ 'method' => $method, 'message' => "{$user}.", ]; }
