How can I check if request was a POST or GET request in Symfony2 or Symfony3
提问by Gottlieb Notschnabel
I just wondered if there is a very easy way (best: a simple $this->container->isGet()I can call) to determine whether the request is a $_POSTor a $_GETrequest.
我只是想知道是否有一种非常简单的方法（最好：$this->container->isGet()我可以调用的简单方法）来确定请求是请求$_POST还是$_GET请求。
According to the docs,
根据文档，
A Request object holds information about the client request. This information can be accessed via several public properties:
request: equivalent of$_POST;query: equivalent of$_GET($request->query->get('name'));
Request 对象保存有关客户端请求的信息。可以通过几个公共属性访问此信息：
request: 相当于$_POST;query: 相当于$_GET($request->query->get('name'));
But I won't be able to use if($request->request)or if($request->query)to check, because both are existing attributes in the Request class.
但我将无法使用if($request->request)或if($request->query)检查，因为两者都是 Request 类中的现有属性。
So I was wondering of Symfony offers something like the
所以我想知道 Symfony 提供了类似的东西
$this->container->isGet();
// or isQuery() or isPost() or isRequest();
mentioned above?
上文提到的？

If you want to do it in controller,
如果你想在控制器中做到这一点，
$this->getRequest()->isMethod('GET');
or in your model (service), inject or pass the Request object to your model first, then do the same like the above.
或者在您的模型（服务）中，首先将 Request 对象注入或传递给您的模型，然后执行与上述相同的操作。
Edit: for Symfony 3 use this code
编辑：对于 Symfony 3 使用此代码
if ($request->isMethod('post')) {
// your code
}

Or this:
或这个：
public function myAction(Request $request)
{
if ($request->isMethod('POST')) {
}
}

Since the answer suggested to use getRequest()which is now deprecated,
You can do it by this:
由于建议使用的答案getRequest()现已弃用，您可以这样做：
$this->get('request')->getMethod() == 'POST'

Or this:
或这个：
use Symfony\Component\HttpFoundation\Request;
$request = Request::createFromGlobals();
if ($request->getMethod() === 'POST' ) {
}

You could do:
你可以这样做：
if($this->request->getRealMethod() == 'post') {
// is post
}
if($this->request->getRealMethod() == 'get') {
// is get
}
Just read a bit about requestobject on Symfony APIpage.
只需在Symfony API页面上阅读一些关于请求对象的内容。
