当我尝试上传与图像断言不匹配的错误文件时，会发生此错误。只接受图像。

的用户类型：
$builder
->add('firstName', 'text', array(
'required' => true
))
->add('lastName', 'text', array(
'required' => true
))
->add('email', 'email', array(
'required' => true
))
->add('job', 'text', array(
'required' => false
))
->add('file', 'file', array(
'label' => false,
'required' => false,
))
;
控制器：
public function updateMyAccountAction($id, Request $request)
{
$entityManager = $this->get('doctrine')->getManager();
$user = $this->get('doctrine')
->getRepository('TestBackBundle:User')
->find($id);
if (!$user) {
throw $this->createNotFoundException('Unable to find User entity.');
}
$editForm = $this->createForm(new UserType(), $user);
$editForm->handleRequest($request);
if ($editForm->isValid()) {
$user->upload();
$entityManager->persist($user);
$entityManager->flush();
$this->get('session')->getFlashBag()->add('success', 'Your profile has been updated');
return $this->redirect($this->generateUrl('my_account', array('id' => $id)));
} else {
$this->get('session')->getFlashBag()->add('error', 'Erreur');
return $this->redirect($this->generateUrl('my_account', array('id' => $id)));
}
}
当我尝试测试图像断言是否工作更新（例如pdf文件）时，会发生此错误。该文件未更新，因此很好。但我的控制器中的闪存包和重定向不起作用...如果我在控制器var_dump("test")中的else中写"test"，则显示错误，Symfony检测到表单是无效。
发生错误时，这是堆栈跟踪的一部分：
在 /home/user/www/sf2/vendor/symfony/symfony/src/Symfony/Component/Security/Core/Authentication/Token/AbstractToken.php 在第155行
152. $this->roles,
153. $this->attributes
154. )
155. );
}
/**
at serialize（array（object（User），true，array（object（Role）），array（））） 在 /home/kevin/www/sf2/vendor/symfony/symfony/src/Symfony/Component/Security/Core/Authentication/Token/AbstractToken.php 在第155行
读它，我觉得使用roles属性来序列化它有一个问题，因为它是一个数组（我们必须将这个属性声明为一个实现UserInterface的数组）
为什么会出现这种错误？

我找到了解决方案：我必须实现Serializable这样的界面：official doc
答案 1 :(得分：0)
DOZ单词的额外精度很少：
最好在图像（或文件，或@Vich \ Uploadable）实体中实现\Serializable ，而不是在用户实体上实现\Serializable，因为您可能会中断登录这种情况。
如果您像我一样使用VichUploader，请不要在用户实体上添加\Serializable并将其添加到@Vich\Uploadable（图像或文件）实体以及这两种方法上：
/** @see \Serializable::serialize() */
public function serialize()
{
return serialize(array(
$this->id,
$this->image,
));
}
/** @see \Serializable::unserialize() */
public function unserialize($serialized)
{
list (
$this->id,
$this->image,
) = unserialize($serialized, array('allowed_classes' => false));
}
