Redis類:
?php
namespace Utils;
use Phalcon\Config\Adapter\Ini as ConfigIni;
class Redis{
private static $redis1;
private static $session;
/**
* 獲取一個(gè)單例的redis對(duì)象
* @param string $name
* @return \Redis
*/
public static function getObj($name='redis1')
{
try{
if(!empty(self::$$name)){
return self::$$name;
}
$config = new ConfigIni(APP_PATH."/config".ENV."/redis.ini");
self::$$name = new \Redis();
self::$$name->connect($config[$name]['host'], $config[$name]['port'],2);
if(isset($config[$name]['password']) !empty($config[$name]['password'])){
self::$$name->auth($config[$name]['password']);
}
self::$$name->select($config[$name]['database']);
}catch (\Exception $exception){
self::$$name = false;
}
return self::$$name;
}
};
定時(shí)任務(wù):
/**
* 訂單任務(wù)
*/
public function orderAction()
{
error_reporting(E_ALL ~E_NOTICE);
$redis = Redis::getObj();
//獲取數(shù)據(jù)庫連接實(shí)例
$db = $this->getDI()->getShared('db');
while (true) {
print_r(' -start- ');
$order_status = 1;
file_put_contents(APP_PATH . "/../domain_order.log", time());
try {
//防止長時(shí)間無任務(wù)導(dǎo)致MySQL超時(shí)
$db->query("select 1");
//出列
$order_info = $redis->lPop('order');
if (!$order_info) {//隊(duì)列為空時(shí)暫停
echo ' -empty- ';
sleep(1);
continue;
}
$order_info = json_decode($order_info, true);
$model_order_info = NetUserOrder::findFirst(['order_sn = :order_sn:','bind'=>['order_sn'=>$order_domain_info_save->order_sn]]);
//未支付
if($model_order_info->pay_status != 200){
echo 'no pay';
continue;
}
//已操作
if ($order_domain_info_save->order_status == 3) {
echo ' -Operated- ';
continue;
}
//事務(wù)開始
$db->begin();
##
這里執(zhí)行訂單流程操作
##
$order_status = 3;//操作成功
//修改訂單狀態(tài)
$order_domain_info_save->order_status = $order_status;
$order_domain_info_save->operation_time = time();
$order_domain_info_save->update();
}
//提交事務(wù)
$db->commit();
printf('### succ order_id' . $order_info['id'] . ' ###');
} catch (\Exception $e) {
//回滾事務(wù)
$db->rollback();
$order_status = 2;//操作失敗
$order_domain_info_save->order_status = $order_status;
$order_domain_info_save->operation_time = time();
$order_domain_info_save->update();
printf(' error ' . $e->getMessage() . ' ');
//異常,發(fā)送通知
Log::error($e->getMessage());
$redis->hSet('order_domain_retry', 'domain_retry_' . $order_info['id'], json_encode($order_info));
}
Redis常用隊(duì)列方法:
//隊(duì)列第一個(gè) =>出列
$Redis->lPop($key);
//入到 =>隊(duì)列最后
$Redis->rPush($key);
//隊(duì)列最后一個(gè) =>出列
$Redis->rPop($key);
//入到 =>隊(duì)列第一個(gè)
$Redis->rPop($key);
//返回整個(gè)列表的值,不出列
$redis->lRange($key,0,-1);
