I have always used other frameworks such as TP and CI to meet the above requirements, and it can be easily realized. Recently, I also want to implement it on SF2 and write an adminBundle to automatically create a backend to provide common functions. However, I encountered the following problem:
Since I want to detect user access permissions globally in the background, I listened to the controller. Obtain the request information before each controller is triggered and check whether the user has given the corresponding permissions. code show as below:
class RunActListener {
protected $securityContext;
public function __construct(SecurityContextInterface $securityContext)
$this->securityContext = $securityContext;
}
public function onRunAct(FilterControllerEvent $event) {
$request = $event->getRequest();
$ajax = $request->isXmlHttpRequest();
if (preg_match('/^\/admin/', $request->getRequestUri())) {
$routeName = $request->get('_route');
if ($this->securityContext->isGranted(array($routeName))) {
} else {
$reffeer = $request->server->get('HTTP_REFERER');
$data['info'] = '您没有权限操作!';
$data['status'] = false;
if ($ajax) {
$event->setController(
function() use ($data) {
return new JsonResponse($data);
});
} else {
$event->setController(
function() use ($data) {
return new Response('<b>您没有足够的访问权限!</b><script>setTimeout("window.history.back(-1)",2000)</script>');
});
//。。。。。
Then I introduced 2 renders in the background layout. The menu and breadcrumb codes are as follows:
<nav id="navigation" class="collapse">
<ul>
{{ render(controller( 'CwpUtilBundle:Menu:showMenu')) }}
</ul>
</nav>
</aside>
<p id="sidebar-separator"></p>
<section id="main" class="clearfix">
<p id="main-header" class="page-header">
{{ render(controller( 'CwpUtilBundle:Menu:showCrumb')) }}
</p>
<p id="main-content">
{% block main %}
{% endblock %}
</p>
</section>
In this way, two sub_requests were initiated, but my requirement is to obtain the url of the parent request in the sub_request to implement my breadcrumbs and menu. There are some troubles in SF. Some experts suggest using get request stack in sub action
/**
* 显示面包屑
* @return type
*/
public function showCrumbAction() {
$request = $this->container->get('request');
$path = $request->server->get('REDIRECT_URL');
$path_arr = explode('/', $path);
$path_len = count($path_arr);
$top_index = (int) ($path_len - 2);
$path_top = $path_arr[$top_index];
$route_arr = $this->get('router')->match($path);
$route = $route_arr['_route'];
$em = $this->getDoctrine()->getManager();
//获取菜单结果集
$top_menu = $em->getRepository('CwpUtilBundle:Menu')->findOneByNode($path_top);
$sec_menu = $em->getRepository('CwpUtilBundle:Menu')->findOneByNode($route);
return $this->render('CwpUtilBundle:Layout:crumb.html.twig', array(
'top_menu' => $top_menu,
'sec_menu' => $sec_menu,
));
}
I tried to get request_stack in the above action, but once I get, it seems that a request was initiated in this action, my listener was triggered, and then executed else, jumping to the prompt that you have insufficient permissions. I was confused and didn't know why.
The listener that monitors kernel.controller, add a judgment, and only check the permissions when the main request is made:
FilterControllerEvent in 2.3 does not have this method, just refer to this logic and write it yourself:
