TP5.1使用 GatewayWorker 进行 socket 通讯

版权声明：本文为博主原创文章，未经博主允许不得转载。 https://blog.csdn.net/Lg632/article/details/81556760

1.安装 Workerman
   composer 安装GatewayWorker内核文件（不包含start_gateway.php start_businessworker.php等启动入口文件）

composer require workerman/gateway-worker

2.创建 Workerman 启动文件
   创建一个自定义命令类文件来启动 Socket 服务端，新建

application/common/command/Workerman.php

<?php
namespace app\common\command;

use app\workerman\Events;
use GatewayWorker\BusinessWorker;
use GatewayWorker\Gateway;
use GatewayWorker\Register;
use think\console\Command;
use think\console\Input;
use think\console\input\Argument;
use think\console\input\Option;
use think\console\Output;
use Workerman\Worker;

class Workerman extends Command
{
    protected function configure()
    {
        $this->setName('workerman')
            ->addArgument('action', Argument::OPTIONAL, "action  start|stop|restart")
            ->addArgument('type', Argument::OPTIONAL, "d -d")
            ->setDescription('workerman chat');
    }
    
    protected function execute(Input $input, Output $output)
    {
        global $argv;
        $action = trim($input->getArgument('action'));
        $type   = trim($input->getArgument('type')) ? '-d' : '';
        
        $argv[0] = 'chat';
        $argv[1] = $action;
        $argv[2] = $type ? '-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    = Events::class;
    }
    
    private function startGateWay()
    {
        $gateway = new Gateway("websocket://0.0.0.0:8282");
        $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');
    }
}

   配置 application/command.php 文件

return [
    'app\common\command\Workerman',
];

3.创建事件监听文件
   创建 application/workerman/Events.php 文件来监听处理 workerman 的各种事件。

<?php
namespace app\workerman;

use GatewayWorker\Lib\Gateway;

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){
    }
}

4.启动 Workerman 服务端
   以debug（调试）方式启动

php think workerman start

php think workerman start d   // 以daemon（守护进程）方式启动

php think workerman stop   

php think workerman restart

php think workerman reload

php think workerman status

   当你看到如下结果的时候，workerman已经启动成功了。

Workerman[chat] start in DEBUG mode
