laravel整合workerman做消息推送系统

官方建议分离 workerman和mvc框架的结合，我去，这不是有点脑缺氧吗？

大量的业务逻辑，去独立增加方法和类库在写一次，实际业务中是不现实和不实际的

gateway增加一些这方面的工作，但是我看了源码之后，就发现还是只能自己做

先增加composer require workerman/workerman  或者walkor/workerman ，但是官方的github是 walkor/workerman，注意一下

可以去 https://packagist.org查看是否有包

首先结合Console做命令

建立一个Command

<?php

namespace App\Console\Commands;

use Illuminate\Console\Command;
use Workerman\Worker;
use App\Work\WorkermanWork;

class Workerman extends Command {

    protected $taskserver;
    /*
     * 操作参数
     * 注意只能在
     * start 启动
     * stop 停止
     * relaod  只能重启逻辑代码，核心workerman_init无法重启，注意看官方文档
     * status 查看状态
     * connections 查看连接状态（需要Workerman版本>=3.5.0）
     *
     */
    protected $action = array('start', 'stop', 'reload', 'status', 'connections');

    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'Workerman {action}';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Workerman';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct() {
        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return mixed
     *
     * 注意
     *
     */
    public function handle() {
        $action = $this->argument('action');

        if (!in_array($action, $this->action)) {
            $this->error('Error Action');
            exit;
        }
        //初始化workerman
        WorkermanWork::workerman_init($action);
    }

}

注册到Kernel

class Kernel extends ConsoleKernel {

    /**
     * The Artisan commands provided by your application.
     *
     * @var array
     */
    protected $commands = [

        \App\Console\Commands\Workerman::class,
    ];

WorkermanWork的内容

<?php

namespace App\Work;

use App\Work\BaseWork as Base;
use Illuminate\Support\Facades\DB;
use App\Work\CommonWork;

use Workerman\Lib\Timer;

    static $connection_count = 0;

        global $argv;

        $argv[0] = 'workerman:websocket';
        $argv[1] = $action;
        $argv[2] = '-d';
//        心跳
        define('HEARTBEAT_TIME', 30);
        //初始化
        $worker = new Worker("websocket://172.17.1.247:9099");
        $worker->name = 'MessagePushWorker';
        //linux 用户线上是www
//        $worker->user = 'www';
        //守护模式信息输出文件地址
//        $worker->stdoutFile = "./workerman.log";
        //工作进程总数 测试环境4个
        $worker->count = 4;
        //正式环境
//        $ws->count = 10;
        //建立链接 处理逻辑
        $worker->onConnect = function($connection) {
//             有新的客户端连接时，连接数+1
            self::$connection_count++;
            self::onConnect($connection);
        };
        //接受消息 处理逻辑
        $worker->onMessage = function($connection, $data) {

            self::onMessage($connection, $data);
        };
        //关闭链接 处理逻辑
        $worker->onClose = function($connection) {
//            客户端关闭时，连接数-1
            self::$connection_count--;
            self::onClose($connection);
        };

        // 进程启动后设置一个30秒运行一次的定时器
//        $worker->onWorkerStart = function($worker) {

        Worker::runAll();
    }

        //测试5秒一次 线上30秒一次
        Timer::add(10, function() use($connection) {

            if (!empty($_SESSION['user_id'])) {
                $Users = Users::where('id', $_SESSION['user_id'])->first();

                    if (!empty($message_list)) {

                    }
                }
//                else {
//                    $connection->send(json_encode(['code' => 201, 'msg' => '无效user_id', 'connections' => self::$connection_count]));
//                }
            }
//            else {
//                $retrun_data = json_encode(['code' => 201, 'msg' => 'session user_id不存在', 'connections' => self::$connection_count]);
//                $connection->send($retrun_data);

                    // 客户端回应服务端的心跳
                    case 'ping':

                        if (empty($Users)) {
                            $connection->send(json_encode(['code' => 201, 'msg' => '用户ID无效或者错误', 'data' => [], 'connections' => self::$connection_count]));
                        } else {

//        $connection->send("return_data: $data ");
    }

    //关闭链接 处理逻辑
    public static function onClose($connection) {

    }

}

建立socket的时间设置一个10秒的定时器，这个基于session的控制，登录之后立即请求发送

{"type":"login","user_id":"24"}

因为如果登录，就检索OperationLog表里属于这个用户ID的消息，每10秒推送一次数据

运行 命令

php artisan Workerman start 启动

$argv[2] = '-d';

注释掉就是测试模式，加上就是守护模式，就是线上使用的

注意：上面是临时测试代码。业务代码使用try catch处理异常和错误
