Symfony2:onKernelResponse被两次调用为MASTER_REQUEST [英] Symfony2 : onKernelResponse called twice as MASTER_REQUEST
问题描述
我正在使用事件监听器onKernelResponse.
I'm using the event listener onKernelResponse.
尽管我使用过:
if (HttpKernelInterface::MASTER_REQUEST != $event->getRequestType()) {
return;
}
我的操作中有两次MASTER_REQUEST，在<!DOCTYPE html> <html> <head>等之前有一个，在布局结束后除外.
It's having a MASTER_REQUEST twice in my action, there is one before the <!DOCTYPE html> <html> <head>etc, and the other one as excepted after the end of the layout.
他是我的services.yml:
history.listener:
class: VENDOR\MyBundle\Service\HistoryListener
arguments: [@doctrine.orm.entity_manager, @logger, @history]
tags:
- { name: kernel.event_listener, event: kernel.controller, method: onKernelController }
- { name: kernel.event_listener, event: kernel.response, method: onKernelResponse }
我做错了吗?
推荐答案
终于找到了问题的根源:调试工具栏！
Finally found the origin of the problem : the debug toolbar !
它实际上发送了一个ajax请求，表示另一个MASTER_REQUEST ..
It actually sends an ajax request, meaning another MASTER_REQUEST..
我的解决方案是对控制器进行过滤，并以白名单/黑名单列出控制器的名称.
My solution is to filter on Controller, with a white/black list of controller's names.
更新:
这是我正在使用的代码(因此，您可以根据需要轻松排除其他一些控制器).
Here is the code I'm using (so you can easily exclude some other controllers if needed).
public function __construct()
{
$this->classesExcluded = array("Symfony\Bundle\WebProfilerBundle\Controller\ProfilerController");
}
public function onKernelController(FilterControllerEvent $event)
{
$controller = $event->getController();
if (!is_array($controller) || HttpKernelInterface::MASTER_REQUEST != $event->getRequestType() || in_array(get_class($controller[0]), $this->classesExcluded)) {
return;
}
// ...
}
