在Symfony2控制器中$ response-> send()之后返回什么?

If I prepare a response in my controller like so:

$response = new Response();
$response->setContent($this->render('mytemplate.html.twig');
$response->send();

Rather than using:

return $this->return('mytemplate.html.twig');

Then I haven't actually returned anything... what should I do after $response->send()? Should I just return true?

    You must return response

    From symfony documentation:

    The goal of a controller is always the same: create and return a Response object.

    Example:

    use Symfony\Component\HttpFoundation\Response;
    
    public function helloAction()
    {
        return new Response('Hello world!');
    }
    

    Another example:

    use Symfony\Component\HttpFoundation\Response;
    
    $content = $this->renderView(
        'AcmeHelloBundle:Hello:index.html.twig',
        array('name' => $name)
    );
    
    return new Response($content);
    

    You can read about it here: http://symfony.com/doc/current/book/controller.html
