tp5.1 swoole 实现异步处理

客户端请求：
<?php
namespace app\index\controller;

class Index
{
    public function index()
    {
        $client = new \swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_SYNC);
        $ret = $client->connect("192.168.10.10", 9502);
        if(empty($ret)) {
            echo 'error!connect to swoole_server failed';
        } else {
            dump('ccc');
            $client->send('blue');//这里只是简单的实现了发送的内容
        }

        echo 'success';
　　}
}

服务端异步处理：

<?php
/**

namespace app\index\controller;

use think\swoole\Server;

class Swoole extends Server
{
    protected $host = '0.0.0.0';
    protected $port = 9502;
    protected $serverType = 'tcp';
    protected $option = [
        'worker_num'=> 4,
        'daemonize'    => false,
        'backlog'  => 128,
        'task_worker_num' => 4,  //任务工作进程
    ];

    public function onConnect($serv, $fd)
    {
        echo "server: handshake success with fd{$fd}\n";
    }

    public function onTask($serv, $task_id, $from_id, $data)
    {
        echo "New AsyncTask[id=$task_id]".PHP_EOL;
        //返回任务执行的结果
        sleep(5);
        $serv->finish("$data -> OK");
    }

    public function onFinish($serv, $task_id, $data)
    {
        echo "AsyncTask[$task_id] Finish: $data".PHP_EOL;
    }

   //接收客户端发送的数据 
　　public function onReceive($server, $fd, $from_id, $data)
    {
        $task_id = $server->task($data);
        echo "开始投递异步任务 id=$task_id\n";
        //$server->send($fd, 'Swoole: '.$data);
    }

    public function onClose($serv, $fd)
    {

    }

}
