symfony2 项目上的 Swiftmailer 附件错误（无法打开文件进行阅读）

Question

我正在开发一个 symfony 项目，我有一个必须使用 swiftmailer 发送邮件的表单。对于解释 -> 用户可以在表单的可选文件上传功能中使用附件。（表格像命令一样保存在 bdd 中，提交表格后我们进行了回顾，并且发送了 3 封邮件（我们每次都不使用附件的两封邮件，只有带附件选项的邮件失败了有一个文件要加入，否则如果我们只使用评论（其他字段可选，像路径一样工作，邮件正在工作）

我希望我的解释清楚易懂，我的英语并不完美，功能也不太容易。由于某些信息的机密性，我只在这里写了与邮件有关的代码，但如果我忘记了什么，请告诉我，我会更新 post.

当我发送一个没有附件的邮件时，我没有遇到任何问题，但是当我尝试加入一个文件时，symfony 给我这个错误：

Unable to open file for reading [uploads/6M.jpg]

我试图在 Whosebug 中的其他 post 上找到解决方案，但没有人在工作。所以我希望你能帮助我。

Commande Controller（我只放了关于附件的代码）：

use Symfony\Component\HttpFoundation\Request;
use OrthoBundle\Entity\Compteur;
use Symfony\Bundle\FrameworkBundle\Controller\Controller; 
use OrthoBundle\Entity\Commandes;
use OrthoBundle\Form\Type\CommandesType;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Session\Session;

class FormulaireController extends Controller
{
    public function createFormulaireAction(Request $request)
    {   
        $em = $this->getDoctrine()->getManager();

       $commande = new Commandes();

        $request = $this->get('request');

        $user = $this->getUser();

        $form = $this->createForm(new CommandesType($user), $commande);

        if ($form->isValid() && $form->isSubmitted()) {

        ***""""""SOME CODE THAT I DON'T PUT ABOUT PERSIST FLUSH THE COMMAND IN DB""""***

       $message = \Swift_Message::newInstance()
            ->setSubject('Commande n°' . $commande->getId())
            ->setFrom(array('mymail@example.com' => 'send from'))
            ->setTo(array('onemail@example.com' => 'destinatory'))
            ->setCharset('utf-8')
            ->setContentType('text/html')
            ->setBody($this->renderView('@Ortho/Mail/mail_impress.html.twig', array(
                'parentUser' => $user->getParent(),
                'commande' => $commande,
            )));
        if ($commande->getWebPath1() != '') {
            $message->attach(\Swift_Attachment::fromPath($commande->getWebPath1()));
        }
        if ($commande->getWebPath2() != '') {
            $message->attach(\Swift_Attachment::fromPath($commande->getWebPath2()));
        }
        if ($commande->getWebPath3() != '') {
            $message->attach(\Swift_Attachment::fromPath($commande->getWebPath3()));
        }
        if ($commande->getWebPath1() != '' or
            $commande->getWebPath2() != '' or
            $commande->getWebPath3() != '' or
            $commande->getCommentaire() != '') {
            $this->get('mailer')->send($message);              
        }

此代码适用于没有附件的邮件，但如果我尝试以文件形式上传邮件，则邮件不会发送。供参考：文件的上传工作和上传的文件保存在MyApp/web/uploads.

CommandeType.php :

<?php

namespace MyBundle\Form\Type;

use MyBundle\Entity\Utilisateurs;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\DateType;

use Symfony\Component\Form\Extension\Core\Type\TextareaType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Doctrine\ORM\EntityRepository;

class CommandesType extends AbstractType
{
private $user;

public function __construct(Utilisateurs $utilisateurs)
{
    $this->user = $utilisateurs;
}
/**
 * @param FormBuilderInterface $builder
 * @param array $options
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('commentaireLabo', TextareaType::class, array(
            'attr' => array(
                'placeholder' => 'Select a product'
            ),
        ))
        ->add('file1', FileType::class, array(
            'required' => false
        ))
        ->add('file2', FileType::class, array(
            'required' => false
        ))
        ->add('file3', FileType::class, array(
            'required' => false
        ))
        ->add('commentairePrestataire', TextareaType::class, array(
            'required' => false
        ));
}

/**
 * @param OptionsResolver $resolver
 */
public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'MyBundle\Entity\Commandes'

    ));
}

}

这里是表格的一部分，查看相关文件：

<fieldset class="smallbloc"> <!-- Bloc n°3 : Les pièces jointes -->
    <h2 class="fs-title">Pièces jointes complémentaires</h2>
    <h3 class="fs-subtitle">Toutes les pièces jointes à apporter à la commande.</h3>

    {{ form_label(form.file1, "Arcade Maxilaire :") }}
    {{ form_errors(form.file1) }}
    {{ form_widget(form.file1) }}

    {{ form_label(form.file2, "Arcade Mandibulaire :") }}
    {{ form_errors(form.file2) }}
    {{ form_widget(form.file2) }}

    {{ form_label(form.file3, "Autre pièces jointe :") }}
    {{ form_errors(form.file3) }}
    {{ form_widget(form.file3) }}

    {{ form_label(form.commentairePrestataire3D, "Commentaires pour le prestataire 3D :") }}
    {{ form_errors(form.commentairePrestataire3D) }}
    {{ form_widget(form.commentairePrestataire3D) }}

    <input type="hidden" id="monthstat" name="monthstat" value="{{ "now"|date("m-Y") }}">

    <input type="button" name="previous" class="previous action-button" value="Précédent"/>
    <input type="submit" name="previous" class="action-button" value="ENVOYER"/>

    {{ form_rest(form) }}
</fieldset>

我希望所有必要的代码都在这里，并且我没有忘记任何东西，如果不是刚刚说的话，我将更新我的 post，并添加错误的部分。或者如果我说了一些无脑的话或者谁不理解的话就说我解释一下。我知道阅读 x) 并不容易。谢谢大家的帮助。

Answer 1

附加文件时必须使用文件系统的绝对路径，例如：

$message->attach(\Swift_Attachment::fromPath($commande->getAbsolutePath1()));

SwiftMailer 运行 "server-side"，它不会访问您的前端以获取您想要附加到邮件的文件。

PS : You might also want to check that your file is actually present in the directory where it should be. Maybe the upload did not work as expected and the file is not present

Answer 2

我有同样的问题，是地址使用错误

$this->container->get("kernel")->getRootDir()."/../public/".$attac

which $attac 是你在 public 目录中的附件文件地址我使用 Symfony flex 版本 4
