在Symfony2中,路由参数可以自动映射到控制器参数,例如:http://a.com/test/foo将返回“foo”
/**
* @Route("/test/{name}")
*/
public function action(Request $request, $name) {
return new Response(print_r($name, true));
}
请参阅http://symfony.com/doc/current/book/routing.html#route-parameters-and-controller-arguments
但我想使用 查询字符串 ,例如:http://a.com/ 测试?name = foo
怎么做? 对我来说,只有3个解决方案:
还有其他解决方案吗?

我为那些想要使用转换器的人提供了代码:
use Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter;
use Sensio\Bundle\FrameworkExtraBundle\Request\ParamConverter\ParamConverterInterface;
use Symfony\Component\HttpFoundation\Request;
/**
* Put specific attribute parameter to query parameters
*/
class QueryStringConverter implements ParamConverterInterface{
public function supports(ParamConverter $configuration) {
return 'querystring' == $configuration->getConverter();
}
public function apply(Request $request, ParamConverter $configuration) {
$param = $configuration->getName();
if (!$request->query->has($param)) {
return false;
}
$value = $request->query->get($param);
$request->attributes->set($param, $value);
}
}
services.yml:
services:
querystring_paramconverter:
class: AppBundle\Extension\QueryStringConverter
tags:
- { name: request.param_converter, converter: querystring }
在您的控制器中:
/**
* @Route("/test")
* @ParamConverter("name", converter="querystring")
*/
public function action(Request $request, $name) {
return new Response(print_r($name, true));
}

基于Remy的答案的改进解决方案,它将参数映射到实体:
<?php
namespace AppBundle\Extension;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter;
use Symfony\Component\HttpFoundation\Request;
use Sensio\Bundle\FrameworkExtraBundle\Request\ParamConverter\DoctrineParamConverter;
/**
* Put specific attribute parameter to query parameters
*/
class QueryStringConverter extends DoctrineParamConverter {
protected function getIdentifier(Request $request, $options, $name)
{
if ($request->query->has($name)) {
return $request->query->get($name);
}
return false;
}
}
services.yml:
services:
querystring_paramconverter:
class: MBS\AppBundle\Extension\QueryStringConverter
arguments: ['@doctrine']
tags:
- { name: request.param_converter, converter: querystring }
在您的控制器中:
/**
* @Route("/test")
* @ParamConverter("myobject")
*/
public function action(Request $request, AnyEntity $myobject) {
return new Response(print_r($myobject->getName(), true));
}

我没有检查过,但似乎FOSRestBundle提供的@QueryParam注释可以做到: http://symfony.com/doc/current/bundles/FOSRestBundle/param_fetcher_listener.html
