如何基于Hyperf实现RabbitMQ+WebSocket消息推送-php教程

资源魔 55 0
引见

基于 Hyperf+ WebSocket +RabbitMQ 完成的一个简略年夜屏幕的音讯推送。

思绪

行使 WebSocket 协定让客户端以及效劳器端放弃有状态的长链接，

保留链接下去的客户端 id。定阅公布者公布的音讯针对已保留的客户端 id 进行播送音讯。

WebSocket 效劳

composer require hyperf/websocket-server

设置装备摆设文件 [config/autoload/server.php]

<?php
return [
    'mode' => 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 前端代码

    function WebSocketTest() {
        if ("WebSocket" in window) {
            console.log("您的阅读器支持 WebSocket!");
            var num = 0
            // 关上一个 web socket
            var ws = new WebSocket("ws://127.0.0.1:12222");
            ws.onopen = function () {
                // Web Socket 已衔接上，应用 send() 办法发送数据
                //alert("数据发送中...");
                //ws.send("发送数据");
            };
            window.setInterval(function () { //每一隔5秒钟发送一次心跳，防止websocket衔接因超时而主动断开
                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) {
                    $(".address").text(d.address)
                }
                if (d.code == 200) {
                    var v = d.data
                    console.log(v);
                    num++
                    var str = `<div class="item">
                                    <p>${v.recordOutTime}</p>
                                    <p>${v.userOutName}</p>
                                    <p>${v.userOutNum}</p>
                                    <p>${v.doorOutName}</p>
                                </div>`
                    $(".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 () {
                // 封闭 websocket
                alert("衔接已封闭...");
            };
        } else {
            alert("您的阅读器没有支持 WebSocket!");
        }
    }

AMQP 组件

composer require hyperf/amqp

设置装备摆设文件 [config/autoload/amqp.php]

<?php
return [
    'default' => [
        '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 生产者代码

<?php
declare(strict_types=1);
namespace App\Amqp\Consumer;
use Hyperf\Amqp\Annotation\Consumer;
use Hyperf\Amqp\Message\ConsumerMessage;
use Hyperf\Amqp\Result;
use Hyperf\Server\Server;
use Hyperf\Server\ServerFactory;
/**
 * @Consumer(exchange="hyperf", routingKey="hyperf", queue="hyperf", nums=1)
 */
class DemoConsumer extends ConsumerMessage
{
    /**
     * rabbmitMQ生产端代码
     * @param $data
     * @return string
     */
    public function consume($data): string
    {
        print_r($data);
        //猎取荟萃中一切的value
        $redis = $this->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;
    }
}

管制器代码

    /**
     * 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' => '老师公寓',
            ]
        );
        $data = \GuzzleHttp\json_encode($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}.",
        ];
    }
