symfony2添加用于路由的动态参数，尝试使用自定义加载程序 [英] symfony2 add dynamic parameter for routing, try with custom loader
问题描述
我尝试在此处设置自定义路由器加载器
I try setup custom router loader like here
http://symfony.com/doc/current/cookbook/routing/custom_route_loader.html
我想添加动态参数对于所有路由（会话的参数）
i want add dynamic parameter for all routes (parameter from session)
这是我的代码
namespace Mea\Crm4Bundle\Routing;
use Mea\Crm4Bundle\Entity\Application;
use Symfony\Component\Config\FileLocatorInterface;
use Symfony\Component\Config\Loader\Loader;
use Symfony\Component\HttpFoundation\Session\Session;
use Symfony\Component\Routing\Loader\AnnotationClassLoader;
use Symfony\Component\Routing\Loader\AnnotationDirectoryLoader;
use Symfony\Component\Routing\Loader\AnnotationFileLoader;
use Symfony\Component\Routing\Loader\YamlFileLoader;
use Symfony\Component\Routing\Route;
use Symfony\Component\Routing\RouteCollection;
use Symfony\Component\Yaml\Exception\ParseException;
use Symfony\Component\Yaml\Parser as YamlParser;
use Symfony\Component\Config\Resource\FileResource;
class AppLoader extends YamlFileLoader
{
private static $availableKeys = array(
'resource', 'type', 'prefix', 'pattern', 'path', 'host', 'schemes', 'methods', 'defaults', 'requirements', 'options', 'condition',
);
private $yamlParser;
private $loaded = false;
/**
* @var
*/
private $annotationClassLoader;
/**
* @var
*/
private $session;
/**
* Constructor.
*
* @param FileLocatorInterface $locator A FileLocatorInterface instance
* @param AnnotationClassLoader $annotationClassLoader
* @param Session $session
*/
public function __construct(FileLocatorInterface $locator, AnnotationClassLoader $annotationClassLoader, Session $session)
{
$this->locator = $locator;
$this->annotationClassLoader = $annotationClassLoader;
$this->session = $session;
}
public function load($file, $type = null)
{
$appId = $this->session->get(
Application::CRM_APP_ID_SESSION
);
$path = $this->locator->locate($file);
if (!stream_is_local($path)) {
throw new \InvalidArgumentException(sprintf('This is not a local file "%s".', $path));
}
if (!file_exists($path)) {
throw new \InvalidArgumentException(sprintf('File "%s" not found.', $path));
}
if (null === $this->yamlParser) {
$this->yamlParser = new YamlParser();
}
try {
$parsedConfig = $this->yamlParser->parse(file_get_contents($path));
} catch (ParseException $e) {
throw new \InvalidArgumentException(sprintf('The file "%s" does not contain valid YAML.', $path), 0, $e);
}
$collection = new RouteCollection();
$collection->addResource(new FileResource($path));
// empty file
if (null === $parsedConfig) {
return $collection;
}
// not an array
if (!is_array($parsedConfig)) {
throw new \InvalidArgumentException(sprintf('The file "%s" must contain a YAML array.', $path));
}
foreach ($parsedConfig as $name => $config) {
$config['defaults']['_applicationid']=$appId;
if (isset($config['pattern'])) {
if (isset($config['path'])) {
throw new \InvalidArgumentException(sprintf('The file "%s" cannot define both a "path" and a "pattern" attribute. Use only "path".', $path));
}
@trigger_error(sprintf('The "pattern" option in file "%s" is deprecated since version 2.2 and will be removed in 3.0. Use the "path" option in the route definition instead.', $path), E_USER_DEPRECATED);
$config['path'] = $config['pattern'];
unset($config['pattern']);
}
$this->validate($config, $name, $path);
if (isset($config['resource'])) {
$this->parseImport($collection, $config, $path, $file);
} else {
$this->parseRoute($collection, $name, $config, $path);
}
}
return $collection;
}
public function supports($resource, $type = null)
{
return 'crmapp' === $type;
}
}
这是routing.yml
here is routing.yml
mea_crm:
resource: @MeaCrm4Bundle/Resources/config/routing.yml
type: crmapp
prefix: /{_applicationid}
defaults: { _applicationid: 5 }
这是服务.yml
app.routing_loader:
class: Mea\Crm4Bundle\Routing\AppLoader
arguments: [@file_locator, @sensio_framework_extra.routing.loader.annot_class,@session]
tags:
- { name: routing.loader }
如果我删除缓存，此加载程序将被触发一次。
所以我认为这不是我所需要的。
我如何覆盖路由器或以其他方式-我希望从会话中设置_aplication id默认值。
This loader is fired once if i remove cache. So i think this is not what i need. How i can override router or in other way - i want setup _aplication id default value from session.
更新1
i设置路由器
这是工作方法
class RouteGenerator extends UrlGenerator
public function doGenerate($variables, $defaults, $requirements, $tokens, $parameters, $name, $referenceType, $hostTokens, array $requiredSchemes = array()){
if(!isset($parameters[MeaCrm4Bundle::CRM_APP_SWITCH_PARAMETER])){
//for test
$parameters[MeaCrm4Bundle::CRM_APP_SWITCH_PARAMETER] = 1212;
}
$url = parent::doGenerate($variables, $defaults, $requirements, $tokens, $parameters, $name, $referenceType, $hostTokens, $requiredSchemes);
return $url;
}
当我添加到parameter.yml
when i add to parameters.yml
router.options.generator_base_class: Mea\Crm4Bundle\Routing\RouteGenerator
我有我想要的-树枝，控制器使用此路由器并设置我的参数。只有一个-这不是服务，所以我没有@session
在这里获得会话的最佳方法是什么？
i have what i want - twig, controlerrs use this router and setup my parameter. Only one - this is not service so i dont have @session What is best method to get session here ?
您可以创建其他类-作为服务吗？我得到了覆盖树枝生成器的示例，但是有一种方法可以按服务而不是类覆盖主路由器？
Thy create other class - as service ? i get example to override twig generator but there exist way to override main router by service not class ?
UPDATE 2
所以我覆盖了路由器-但没有会话-我需要在这里
so i override router - but dont have session - i need like here
public function __construct(RouteCollection $routes, RequestContext $context, LoggerInterface $logger = null, Session $session)
{
$this->routes = $routes;
$this->context = $context;
$this->logger = $logger;
$this->session = $session;
}
但是现在如何-如何在此处进行会话？
but what now - how get session here ?
推荐答案
我想您应该尝试实现 Symfony\Component\Routing\Generator\ UrlGeneratorInterface 。
或尝试扩展路由器并将其注册为服务。
Or try to extends the router and register it as a service.
然后您需要根据 TwigBundle 提供的扩展名来创建适当的扩展名：
Then you need to create the appropriate extension following the one provided by the TwigBundle:
<service id="twig.extension.routing" class="Symfony\Bridge\Twig\Extension\RoutingExtension" public="false">
<argument type="service" id="router" />
</service>
将自定义生成器传递给它：
To pass it your custom generator:
<service id="app.twig.url_generator" class="AppBundle\Twig\Extension\RoutingExtension" public="false">
<argument type="service" id="app.url_generator">
</service>
<service id="app.url_generator" class="AppBundle\Routing\AppUrlGenerator" public="false">
<argument type="service" id="router">
<argument type="service" id="session">
</service>
您需要装饰路由器以加载路由集合。
You need to decorate the router to load the route collection.
别忘了注册树枝扩展名：）
And don't forget to register the twig extension :)
