\ Swift_Mailer期待變量

Question

在這種question:有人說：

Simply remove the $mailer from your constructor (you are not in a service, you are in a controller) , and use $this->get('mailer')->send($message);

我做到了這一點，但現在我得到這個錯誤：

Parse error: syntax error, unexpected ',', expecting variable (T_VARIABLE)(line: 20)

這裏是我的代碼

<?php 

namespace AppBundle\Controller; 

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; 
use Symfony\Bundle\FrameworkBundle\Controller\Controller; 
use Symfony\Component\Form\Extension\Core\Type\CheckboxType; 
use Symfony\Component\Form\Extension\Core\Type\EmailType; 
use Symfony\Component\Form\Extension\Core\Type\SubmitType; 
use Symfony\Component\Form\Extension\Core\Type\TextType; 
use Symfony\Component\Form\SubmitButton; 
use Symfony\Component\HttpFoundation\Request; 
use AppBundle\Entity\News; 

class DefaultController extends Controller 
{ 
    /** 
     * @Route("/", name="homepage") 
     */ 
public function indexAction(\Swift_Mailer, Request $request) //Here's the error 
{ 
    $em = $this->getDoctrine()->getManager(); 

    $NewsLetters = new News(); 

    $formBuilder = $this->createFormBuilder($NewsLetters); 
    $formBuilder 
     ->add('email', EmailType::class) 
     ->add('nom', TextType::class, array(
      'required' => false, 
     )) 
     ->add('newsWebsite', CheckboxType::class) 
     ->add('newsStylo', CheckboxType::class, array(
      'required' => false, 
     )) 
     ->add('newsCrayon', CheckboxType::class, array(
    'required' => false, 
     )) 
     ->add('newsFeutre', CheckboxType::class, array(
    'required' => false, 
     )) 
     ->add('valider', SubmitType::class); 

    $form = $formBuilder->getForm(); 
    $form->handleRequest($request); 

    if($form->isValid() && $form->isSubmitted()) { 
     $NewsLetters = $form->getData(); 

     if(!$NewsLetters->getNom()) { 
      $NewsLetters->setNom("Anonyme"); 
     } 

     $message = (new \Swift_Message('Confirmation d\'inscription à la newsletter')) 
      ->setFrom('ez@zezezezeeze.fr') 
      ->setTo('kurokncjb@gmail.com') 
      ->setBody(
       $this->renderView('emails/confirmationEmalil.html.twig'), 'text/html' 
      ); 
     $this->get('mailer')->send($message); 


     $em->persist($NewsLetters); 
     $em->flush(); 

    } 
    return $this->render('default/index.html.twig', array(
    'form' => $form->createView() 
)); 
} 
} 

感謝你的幫助 ！！

既然你不使用$郵件，

indexAction(\Swift_Mailer, Request $request) 

應與

更換

indexAction(Request $request)
