老师你帮我看一下.我用Di容器获取Redis的内容刷新页面十次.才会出现2～3的数据.其他返回的都是空值, 用原生的Redis去获取就能一直拿到数据

获取数据

$videoData = Di::getInstance()->get('REDIS')->get('index_video_data_cat_id_' . $catId);
//        $redis = new Redis();
//        $redis->connect(\Yaconf::get('redis.host'), \Yaconf::get('redis.port'), \Yaconf::get('redis.time_out'));
//        $videoData = $redis->get('index_video_data_cat_id_' . $catId);
        return $this->writeJson(Status::CODE_OK, 'ok', $videoData);

Di注册

public static function initialize()
{
    Di::getInstance()->set('REDIS', Redis::getInstance());
}
