问题描述
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.只接受图片.
用户实体:

$builder->add('firstName', 'text', array('必需' =>真的))->add('lastName', 'text', array('必需' =>真的))->add('email', 'email', array('必需' =>真的))->add('job', 'text', array('必需' =>错误的))->add('文件', '文件', 数组('标签' =>错误的，'必需' =>错误的，));控制器:
公共函数 updateMyAccountAction($id, Request $request){$entityManager = $this->get('doctrine')->getManager();$user = $this->get('doctrine')->getRepository('TestBackBundle:User')-> 查找($ id)；如果(！$用户){throw $this->createNotFoundException('无法找到用户实体.');}$editForm = $this->createForm(new UserType(), $user);$editForm->handleRequest($request);如果 ($editForm->isValid()) {$用户->上传()；$entityManager->persist($user);$entityManager->flush();$this->get('session')->getFlashBag()->add('success', '您的个人资料已更新');return $this->redirect($this->generateUrl('my_account', array('id' => $id)));} 别的 {$this->get('session')->getFlashBag()->add('error', 'Erreur');return $this->redirect($this->generateUrl('my_account', array('id' => $id)));}}当我尝试测试图像断言是否可以更新 pdf 文件时，会发生此错误.文件没有更新，所以很好.但是我的闪存包和控制器中的重定向不起作用...如果我在控制器的 else 中写入 var_dump("test") 显示 "test"并且错误也是如此 Symfony 检测到表单无效.
这是发生错误时堆栈跟踪的一部分:
在/home/user/www/sf2/vendor/symfony/symfony/src/Symfony/Component/Security/Core/Authentication/Token/AbstractToken.php在第 155 行
152.$this->角色，153. $this-> 属性154.)155.);}/**
在序列化(数组(对象(用户)，真，数组(对象(角色))，数组()))在/home/kevin/www/sf2/vendor/symfony/symfony/src/Symfony/Component/Security/Core/Authentication/Token/AbstractToken.php在第 155 行
看了，感觉是roles属性序列化有问题，因为是数组(我们要声明这个属性为数组实现UserInterface)
那么为什么会出现这个错误呢?
解决方案
我找到了解决方案:我必须像这样实现 Serializable 接口:官方文档
This error occurs when I try to upload a bad file which does not match with the image assert. Only image are accepted.

controller :
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)));
}
}
When I try to test if the image assert works updating for example a pdf file, this error occurs. The file is not updated so it is good. But my flash bag and redirection in my controller don't work... if I write var_dump("test") in the else in my controller "test" is displayed and the error too so Symfony detects that the form is not valid.
This is a part of the Stack Trace when error occurs :
152. $this->roles,
153. $this->attributes
154. )
155. );
}
/**
Reading it, I feel that there is a problem with the roles attribute to serialize it because it is an array (we have to declare this attribute as an array implementing UserInterface)
So why this error occurs ?
解决方案
I have found the solution : I had to implement Serializable interface like this : official doc
