Symfony 2使用POST重定向

在Symfony 2中，我的控制器中包含以下代码:

In Symfony 2 I have the following code in my Controller:

// prepare to render the seller info panel
$response = array(
    'data' => $data,
);

// render the seller info panel
return $this->redirect($this->generateUrl('route', $response));

其中的路线是:

route:
    pattern:  /listing/complete/{data}
    defaults: { _controller: FooBundle:Foo:action }
    requirements:
        _method:  POST

这无效，因为重定向正在发出GET请求.我也尝试过这种模式，但是它与路由不匹配:

This doesn't work since the redirect is making a GET request. I've also tried it this pattern, but its not matching the route:

route:
    pattern:  /listing/complete
    defaults: { _controller: FooBundle:Foo:action }
    requirements:
        _method:  POST

我发现路由文档无济于事.有没有一种方法可以使重定向发出POST请求?路线会是什么样子，我是否必须在控制器中做任何事情才能使其实现?

I've found the routing documentation unhelpful. Is there a way that I can have the redirect make a POST request? What would the route look like, and do I have to do anything in the controller to make it happen?
