[英]How can I get Request object inside a class in Symfony 2?
I have a class in Symfony that implements an interface. 我在Symfony中有一个实现接口的类。 I need to have $request to have POST params. 我需要有$ para请求POST params。 This is my function: 这是我的功能:
class WebserviceUserProvider implements UserProviderInterface
{
public function loadUserByUsername($username)
{
$salt = "";
$roles = "";
// make a call to your webservice here
.....
}
...
}
I can't do this: 我不能这样做:
public function loadUserByUsername($username, Request $request)
because i need to implement the interface, and i get this error: 因为我需要实现接口,我得到这个错误:
FatalErrorException: Compile Error: Declaration of Actas\\Gestion\\UserBundle\\Security\\User\\WebserviceUserProvider::loadUserByUsername() must be compatible with Symfony\\Component\\Security\\Core\\User\\UserProviderInterface::loadUserByUsername($username) FatalErrorException:编译错误:Actas \\ Gestion \\ UserBundle \\ Security \\ User \\ WebserviceUserProvider :: loadUserByUsername()声明必须与Symfony \\ Component \\ Security \\ Core \\ User \\ UserProviderInterface :: loadUserByUsername($ username)兼容
How can i get the request params? 我如何获得请求参数? This class is called from login, and i need the password sent by it to use a WebService to authenticate the user. 这个类是从登录调用的,我需要它发送的密码才能使用WebService来验证用户。
Thank you very much in advance! 非常感谢你提前!
This is my services.xml in the Bundle: 这是我在Bundle中的services.xml:
# src/Actas/Gestion/UserBundle/Resources/config/services.yml
parameters:
webservice_user_provider.class: Actas\Gestion\UserBundle\Security\User\WebserviceUserProvider
services:
webservice_user_provider:
class: "%webservice_user_provider.class%"
scope: container
calls:
- [setServiceContainer , ["@service_container"]]
use Symfony\Component\HttpFoundation\RequestStack;
class NewService
{
protected $request;
public function setRequest(RequestStack $request_stack)
{
$this->request = $request_stack->getCurrentRequest();
}
}
In Config file 在配置文件中
services:
new.service:
class: Acme\DemoBundle\NewService
calls:
- [setRequest, [@request_stack]]

In addition to Czechnology's answer, you could also inject the request using a setter method. 除了Czechnology的答案,您还可以使用setter方法注入请求。 In services.yml add: 在services.yml中添加:
my_service:
class: Acme\DemoBundle\Service\WebserviceUserProvider
scope: request
calls:
- [setRequest , ["@request"]]
Then declare your class like this: 然后像这样声明你的类:
use Symfony\Component\HttpFoundation\Request;
class WebserviceUserProvider implements UserProviderInterface {
private $request;
public function setRequest( Request $request ) {
$this->request = $request;
}
// ...
}
If you have scope widening issues, you could also try injecting the service container and getting the requesting from it. 如果您有范围扩大问题,您还可以尝试注入服务容器并从中获取请求。 In services declare your service like this: 在服务中声明您的服务如下:
my_service:
class: Acme\DemoBundle\Service\WebserviceUserProvider
calls:
- [setRequest , ["@service_container"]]
Now just use the container to get the request: 现在只需使用容器来获取请求:
use Symfony\Component\DependencyInjection\ContainerInterface;
use Symfony\Component\HttpFoundation\Request;
class WebserviceUserProvider implements UserProviderInterface {
private $request;
public function setRequest( ContainerInterface $container ) {
$this->request = $container->get('request');
}
// ...
}
How do you load the service? 你如何加载服务? You can inject various stuff in the service: 您可以在服务中注入各种内容:
my_service:
class: Acme\DemoBundle\Service\WebserviceUserProvider
arguments: [@request]
scope: request
and use it in the constructor 并在构造函数中使用它
use Symfony\Component\HttpFoundation\Request;
class WebserviceUserProvider implements UserProviderInterface {
private $request;
public function __construct(Request $request) {
$this->request = $request;
}
// ...
}
I had a similar problem. 我遇到了类似的问题。 May be it helps this solution. 可能有助于这个解决方案。 You can inject the @service_container to the service. 您可以将@service_container注入服务。 Then you can check if the scope 'request' is active and get then the request. 然后,您可以检查范围“请求”是否处于活动状态,然后获取请求。 This is a service for creating a global variable for accesing the language variables from twig. 这是一个用于创建全局变量的服务,用于从twig访问语言变量。

class IdiomaService {
private $idioma;
/**

*/
public function __construct(Container $container, EntityManager $manager, SecurityContext $context){ //, $request ) {
if ($container->isScopeActive('request')) {
$_locale = $container->get('request')->getLocale();
}else{
$_locale = 'es';
}
$this->idioma = $manager->getRepository ( 'BackBundle:Idioma' )->findOneByCodigo ( $_locale);
}
public function getIdioma() {
return $this->idioma;
}
}
