PHP 在 Laravel 中使用 Workerman 进行 socket 通讯

安装 Workerman

由于要使用客户端点对点通讯，选择了 workerman/gateway-worker 的扩展包，它已经引入了 workerman/workerman 。

$ composer require workerman/gateway-worker

创建 Workerman 启动文件

创建一个 artisan 命令行工具来启动 Socket 服务端，在 app/Console/Commands 目录下建立命令行文件。

<?php

namespace App\Console\Commands;

use GatewayWorker\BusinessWorker;
use GatewayWorker\Gateway;
use GatewayWorker\Register;
use Illuminate\Console\Command;
use Workerman\Worker;

class WorkermanCommand extends Command
{

    protected $signature = 'workman {action} {--d}';

    protected $description = 'Start a Workerman server.';

    public function handle()
    {
        global $argv;
        $action = $this->argument('action');

        $argv[0] = 'wk';
        $argv[1] = $action;
        $argv[2] = $this->option('d') ? '-d' : '';

        $this->start();
    }

    private function start()
    {
        $this->startGateWay();
        $this->startBusinessWorker();
        $this->startRegister();
        Worker::runAll();
    }

    private function startBusinessWorker()
    {
        $worker                  = new BusinessWorker();
        $worker->name            = 'BusinessWorker';
        $worker->count           = 1;
        $worker->registerAddress = '127.0.0.1:1236';
        $worker->eventHandler    = \App\Workerman\Events::class;
    }

    private function startGateWay()
    {
        $gateway = new Gateway("websocket://0.0.0.0:2346");
        $gateway->name                 = 'Gateway';
        $gateway->count                = 1;
        $gateway->lanIp                = '127.0.0.1';
        $gateway->startPort            = 2300;
        $gateway->pingInterval         = 30;
        $gateway->pingNotResponseLimit = 0;
        $gateway->pingData             = '{"type":"@heart@"}';
        $gateway->registerAddress      = '127.0.0.1:1236';
    }

    private function startRegister()
    {
        new Register('text://0.0.0.0:1236');
    }
}

创建事件监听文件

创建一个 app/Workerman/Events.php 文件来监听处理 workman 的各种事件。

<?php

namespace App\Workerman;

class Events
{

    public static function onWorkerStart($businessWorker)
    {
    }

    public static function onConnect($client_id)
    {
    }

    public static function onWebSocketConnect($client_id, $data)
    {
    }

    public static function onMessage($client_id, $message)
    {
    }

    public static function onClose($client_id)
    {
    }
}

启动 Workerman 服务端

在命令行里面执行，支持的命令大概有 start|stop|restart，其中 -d 的意思是 daemon 模式。

$ php artisan workman start -d

当你看到如下结果的时候，workman 已经启动成功了。

Workerman[wk] start in DEBUG mode
----------------------- WORKERMAN -----------------------------

Press Ctrl+C to stop. Start success.
