Symfony2动态路由 - 缓存问题 [英] Symfony2 dynamic routing - caching issue

问题描述

我正在尝试创建动态路线，因为我创建了一个CMS，其中创建的每个页面都可以与路由相关联。我正在使用此链接的示例 - http：// php-和-symfony.matthiasnoback.nl/2012/01/symfony2-dynamically-add-routes/ ，并且一切正常，但是路由被缓存，因此一个路由将工作，但是下一个路由将不会，除非我清除缓存。是否可以在此阶段删除路由缓存，还是有其他选择？我不想删除每个页面加载的整个缓存目录，因为这是没有意义的。以下是示例代码：

 命名空间Acme\RoutingBundle\Routing; 
 
使用Symfony\Component\Config\Loader\LoaderInterface; 
使用Symfony\Component\Config\Loader\LoaderResolver; 
使用Symfony\Component\Routing\Route; 
使用Symfony\Component\Routing\RouteCollection; 
 
 class ExtraLoader实现LoaderInterface 
 {
 private $ loaded = false;新新p新新新旗新新新新新旗新新旗新新旗旗哨旗新新新新新新旗新新旗200新新新新旗新新名： \\ RuntimeException（'不要加载这个加载器两次'）; 
} 
 
 $ routes = new RouteCollection（）; 
 
 $ pattern ='/ extra'; 
 $ defaults = array（
'_controller'=>'AcmeRoutingBundle：Demo：extraRoute'，
）; 
 
 $ route = new Route（$ pattern，$ defaults）; 
 $ routes-> add（'extraRoute'，$ route）; 
 
 return $ routes; 
} 
 
 public function supports（$ resource，$ type = null）
 {
 return'extra'=== $ type; 
} 
 
 public function getResolver（）
 {
} 
 
 public function setResolver（LoaderResolver $ resolver）

< tag name =routing.loader>< / tag> 
< / service> 
< / services> 
< / container> 
  

我们需要的最后一件事是/app/config/routing.yml中的一些额外的行：

  AcmeRoutingBundle：
 resource：。 X- 20045454545 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- ，因为每个新路由都必须清除缓存，所以你将被hdd / ssd绑定到无用的清除缓存。 
另一种方法是在控制器中创建一个新方法，该方法接受GET的动态页面，并以枝条显示动态内容。
 
 
 
您可以创建一个服务呈现动态页面，这将简化事情。
 
I'm trying to create dynamic routes as I have created a CMS where each page created can be associated to a route. I'm using the example from this link - http://php-and-symfony.matthiasnoback.nl/2012/01/symfony2-dynamically-add-routes/ and all works fine, however the routing is cached, therefore one route will work but then the next won't unless I clear the cache. Is it possible to remove just the routing cache at this stage or is there another alternative? I don't want to remove the whole cache directory on each page load as that wouldn't make sense. Here is the example code:
namespace Acme\RoutingBundle\Routing;

use Symfony\Component\Config\Loader\LoaderInterface;
use Symfony\Component\Config\Loader\LoaderResolver;
use Symfony\Component\Routing\Route;
use Symfony\Component\Routing\RouteCollection;

class ExtraLoader implements LoaderInterface
{
private $loaded = false;

public function load($resource, $type = null)
{
    if (true === $this->loaded) {
        throw new \RuntimeException('Do not add this loader twice');
    }

    $routes = new RouteCollection();

    $pattern = '/extra';
    $defaults = array(
        '_controller' => 'AcmeRoutingBundle:Demo:extraRoute',
    );

    $route = new Route($pattern, $defaults);
    $routes->add('extraRoute', $route);

    return $routes;
}

public function supports($resource, $type = null)
{
    return 'extra' === $type;
}

public function getResolver()
{
}

public function setResolver(LoaderResolver $resolver)
{
    // irrelevant to us, since we don't need a resolver
}
}
Then I've made a service for the ExtraLoader:
<!-- in /src/Acme/RoutingBundle/Resources/config/services.xml -->
<?xml version="1.0" ?>
<container xmlns="http://symfony.com/schema/dic/services"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://symfony.com/schema/dic/services       http://symfony.com/schema/dic/services/services-1.0.xsd">

    <services>
        <service id="acme.routing_loader" class="Acme\RoutingBundle\Routing\ExtraLoader">
            <tag name="routing.loader"></tag>
        </service>
    </services>
</container>
The last thing we need, is a few extra lines in /app/config/routing.yml:
AcmeRoutingBundle:
    resource: .
    type: extra

解决方案
This is quite inefficient, because with each new route you have to clear cache, so you'll be bound by hdd/ssd with useless clear cache.
The alternative is to create a new method in controller which accepts a dynamic page on GET and to show the dynamic content in twig.

You can create a service to render the dynamic pages, which will simplify things.
