在控制器中获取“请求"对象的最佳方法是什么?
问题描述：
我已经看到请求对象作为参数传递给控制器操作方法，如下所示:
I have seen the request object being passed to the controller action method as a parameter like this:
public function addAddressAction(Request $request)
{
...
}
我也在 action 方法中看到它从容器中获取:
I have also seen it within the action method where it is gotten from the container:
public function addAddressAction()
{
$request = $this->getRequest();
...
}
哪个更好?重要吗?
答
如果你深入了解 Symfony2 基础控制器代码，你可能会注意到 getRequest() 从 2.4 版本开始被标记为已弃用，并将在 3.0 中移除.>
If you take a deeper look at the Symfony2 Base Controller code, you may notice that getRequest() is marked as deprecated since version 2.4 and will be removed in 3.0.
/*
* ...
* @deprecated Deprecated since version 2.4, to be removed in 3.0. Ask
* Symfony to inject the Request object into your controller
* method instead by type hinting it in the method's signature.
*/
public function getRequest()
{
return $this->container->get('request_stack')->getCurrentRequest();
}
由以下演变引入，
结论，
您的请求应该是您的操作签名的一部分.
Your Request should then be part of your action's signature.
