Swoole Task 的运用。

Swoole 异步Task,重要完成挪用异步使命的实行。 (引荐进修: swoole视频教程)

经常运用的场景:异步付出处置惩罚、异步定单处置惩罚、异步日记处置惩罚、异步发送邮件/短信等。

Swoole 的完成体式格局是 worker 历程处置惩罚数据要求,分配给 task 历程实行。

官方引见:

task 底层运用Unix Socket管道通讯,是全内存的,没有IO斲丧。单历程读写机能可达100万/s,差别的历程运用差别的管道通讯,能够最大化应用多核。

当地版本:PHP 7.2.6、Swoole 4.3.1。

不多说,先看效果图:

代码

server.php

class Server
{
    private $serv;

    public function __construct() {
        $this->serv = new swoole_server('0.0.0.0', 9501);
        $this->serv->set([
            'worker_num'      => 2, //开启2个worker历程
            'max_request'     => 4, //每一个worker历程 max_request设置为4次
            'task_worker_num' => 4, //开启4个task历程
            'dispatch_mode'   => 2, //数据包分发战略 - 牢固形式
        ]);

        $this->serv->on('Start', [$this, 'onStart']);
        $this->serv->on('Connect', [$this, 'onConnect']);
        $this->serv->on("Receive", [$this, 'onReceive']);
        $this->serv->on("Close", [$this, 'onClose']);
        $this->serv->on("Task", [$this, 'onTask']);
        $this->serv->on("Finish", [$this, 'onFinish']);

        $this->serv->start();
    }

    public function onStart($serv) {
        echo "#### onStart ####".PHP_EOL;
        echo "SWOOLE ".SWOOLE_VERSION . " 效劳已启动".PHP_EOL;
        echo "master_pid: {$serv->master_pid}".PHP_EOL;
        echo "manager_pid: {$serv->manager_pid}".PHP_EOL;
        echo "########".PHP_EOL.PHP_EOL;
    }

    public function onConnect($serv, $fd) {
        echo "#### onConnect ####".PHP_EOL;
        echo "客户端:".$fd." 已衔接".PHP_EOL;

    }

    public function onReceive($serv, $fd, $from_id, $data) {
        echo "#### onReceive ####".PHP_EOL;
        echo "worker_pid: {$serv->worker_pid}".PHP_EOL;
        echo "客户端:{$fd} 发来的Email:{$data}".PHP_EOL;
        $param = [
            'fd'    => $fd,
            'email' => $data
        ];
        $rs = $serv->task(json_encode($param));
        if ($rs === false) {
            echo "使命分配失利 Task ".$rs.PHP_EOL;
        } else {
            echo "使命分配胜利 Task ".$rs.PHP_EOL;
        }
        echo "########".PHP_EOL.PHP_EOL;
    }

    public function onTask($serv, $task_id, $from_id, $data) {
        echo "#### onTask ####".PHP_EOL;
        echo "#{$serv->worker_id} onTask: [PID={$serv->worker_pid}]: task_id={$task_id}".PHP_EOL;

        //营业代码
        for($i = 1 ; $i <= 5 ; $i ++ ) {
            sleep(2);
            echo "Task {$task_id} 已完成了 {$i}/5 的使命".PHP_EOL;
        }

        $data_arr = json_decode($data, true);
        $serv->send($data_arr['fd'] , 'Email:'.$data_arr['email'].',发送胜利');
        $serv->finish($data);
        echo "########".PHP_EOL.PHP_EOL;
    }

    public function onFinish($serv,$task_id, $data) {
        echo "#### onFinish ####".PHP_EOL;
        echo "Task {$task_id} 已完成".PHP_EOL;
        echo "########".PHP_EOL.PHP_EOL;
    }

    public function onClose($serv, $fd) {
        echo "Client Close.".PHP_EOL;
    }
}

$server = new Server();

client.php

<?php
