實用！Swoole + Redis 佇列 訂單處理系統

配置

$serv = new swoole_server("127.0.0.1", 9501);
$serv->set(array(
    'worker_num' => 4,
    'task_worker_num' => 8,
));

啟動

$serv->on('workerStart', function($serv, $worker_id) {
    //處理訂單
    $redis = new redis;
    $redis->connect('127.0.0.1', 6379);
    $serv->redis = $redis;
    if($worker_id == 0){
        swoole_timer_tick(500, function ($timer_id) use($serv,$worker_id) {
             $serv->task('queue');
         });
    }
});

$serv->start();

Task非同步處理任務

簡單邏輯示例，具體根據實際業務情況處理

$serv->on('Task', function (swoole_server $serv, $task_id, $from_id, $data) {
    $redis = $serv->redis;
    $orders = $redis->lrange('queue',0,-1);
    foreach ($orders as $i => $order){
        $info = json_decode($order, true);
        if(empty($info)){
            break;
        }
        *** ...訂單處理邏輯... ***
        //處理完成，刪除
        $redis->lTrim('queue', 1, -1);
   }
    $serv->finish($data);
});

其他

$serv->on('receive', function (swoole_server $serv, $fd, $reactor_id, $data) {
});
$serv->on('Finish', function (swoole_server $serv, $task_id, $data) {
});
