php使用Swoole来实现实时异步任务队列

在打算放置脚本的目录（你也可以自行新建）新建Server.php，代码如下:

<?php

class Server {

    private $server;

    public function __construct() {
        $this->server = new swoole_server("0.0.0.0", 9501);

        $this->server->set([
            'worker_num' => 1, //一般设置为服务器CPU数的1-4倍
            'daemonize' => 1, //以守护进程执行
            'max_request' => 10000,
            'dispatch_mode' => 2,
            'task_worker_num' => 8, //task进程的数量
            "task_ipc_mode " => 3, //使用消息队列通信，并设置为争抢模式
            //"log_file" => "log/taskqueueu.log" ,//日志
        ]);

        $this->server->on('Receive', [$this, 'onReceive']);
        $this->server->on('Task', [$this, 'onTask']);
        $this->server->on('Finish', [$this, 'onFinish']);

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

    public function onReceive(swoole_server $server, $fd, $from_id, $data) {
        //echo "Get Message From Client {$fd}:{$data}\n";
        // send a task to task worker.
        $server->task($data);
    }

    public function onTask($server, $task_id, $from_id, $data) {
        $data = json_decode($data, true);

        return $this->sendEmail($data);
    }

    public function onFinish($serv, $task_id, $data) {
        //echo "Task {$task_id} finish\n";
        //echo "Result: {$data}\n";
    }

    protected function sendEmail($data) {
        //to do send email
        return true;
    }

}

$server = new Server();

客户端

<?php

class Client {

    private $client;

    public function __construct() {
        $this->client = new swoole_client(SWOOLE_SOCK_TCP);
    }

    public function connect() {
        if (!$this->client->connect("127.0.0.1", 9501, 1)) {
            throw new Exception(sprintf('Swoole Error: %s', $this->client->errCode));
        }
    }

    public function send(array $data) {
        if ($this->client->isConnected()) {
            return $this->client->send($data);
        }
    }

    public function close() {
        $this->client->close();
    }
}

$data = [
    'from_email' => 'xxx.@qq.com',
    'to_email' => 'xx.@163.com',
    'title' => '',
    'content' => ''
];

$client = new Client();
$client->connect();

echo $client->send($data) ? 'success' : 'fail';

$client->close();
