symfony2 - 输出pdf页面

Question

I'm trying to create an action which will return a pdf (HTML to PDF).

I have a button in my twig file which calls in AJAX a routing pattern which will call the next controller action:

public function pageToPDFAction(){
    $html = file_get_contents("http://www.google.com");      
    $headers = array(
        'Content-type' => 'application/pdf'
    );
    $response = new Response($html,200,$headers);
    return $response;
}

The output I'm getting is in fact the google.com website, but what I want to get is the browser opening a pdf file like it happens when you click on a pdf file.

How can I achieve that? what am I missing?

You can use KnpSnappyBundle. It creates either pdf or image files from your html documents using the webkit engine. You can see example code in the README file.
