1、代码设置： （注释方式） use Sensio\Bundle\FrameworkExtraBundle\Configuration\Cache;
/** @Cache(smaxage="3600", maxage="3600", public=true) */
（手动方式）
$cacheTime = 3600;
$response = new JsonResponse($channelDatas, 200);
$response->setPublic()->setMaxAge($cacheTime)->setSharedMaxAge($cacheTime);
2、nginx 配置
location ~ \.php($|/) {
include fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_cache fastcgicache; //必须加上
}
