本文介绍了不允许序列化 'SymfonyComponentHttpFoundationFileUploadedFile'的处理方法，对大家解决问题具有一定的参考价值

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:

isActive = true;$this->salt = md5(uniqid(null, true));}/*** 获取身份证** @return 整数*/公共函数 getId(){返回 $this->id;}/*** 设置姓氏** @param string $lastName* @return 用户*/公共函数 setLastName($lastName){$this->lastName = $lastName;返回 $this;}/*** 获取姓氏** @return 字符串*/公共函数 getLastName(){返回 $this->lastName;}/*** 设置名字** @param 字符串 $firstName* @return 用户*/公共函数 setFirstName($firstName){$this->firstName = $firstName;返回 $this;}/*** 获取名字** @return 字符串*/公共函数 getFirstName(){返回 $this->firstName;}/*** 设置工作** @param 字符串 $job* @return 用户*/公共函数 setJob($job){$this->job = $job;返回 $this;}/*** 找工作** @return 字符串*/公共函数 getJob(){返回 $this->job;}/*** 设置邮箱** @param string $email* @return 用户*/公共函数 setEmail($email){$this->email = $email;返回 $this;}/*** 获取电子邮件** @return 字符串*/公共函数 getEmail(){返回 $this->email;}/*** 设置密码** @param string $password* @return 用户*/公共函数 setPassword($password){$this->password = $password;返回 $this;}/*** 获取密码** @return 字符串*/公共函数 getPassword(){返回 $this->password;}/*** 放盐** @param 字符串 $salt* @return 用户*/公共函数 setSalt($salt){$this->salt = $salt;返回 $this;}/*** 拿盐** @return 字符串*/公共函数 getSalt(){返回 $this->salt;}/*** 设置角色** @param 数组 $role* @throws InvalidArgumentException* @return 用户*/公共函数 setRoles($role){if(array_diff($role, array("ROLE_SUPER_ADMIN", "ROLE_ADMIN", "ROLE_CUSTOMER"))) {throw new InvalidArgumentException("坏角色");}$this->roles = $role;返回 $this;}/*** 获取角色** @return 数组*/公共函数 getRoles(){返回 $this->roles;}/*** 设置 isActive** @param boolean $isActive* @return 用户*/公共函数 setIsActive($isActive){$this->isActive = $isActive;返回 $this;}/*** 获取 isActive** @return 布尔值*/公共函数 getIsActive(){返回 $this->isActive;}/*** @inheritDoc*/公共函数eraseCredentials(){}/*** 设置用户名** @param string $email** @return 字符串*/公共函数 setUsername($email){$this->email = $email;返回 $this;}/*** 获取用户名** @return 字符串*/公共函数 getUsername(){返回 $this->email;}公共函数 getAbsolutePath(){返回 null === $this->path ?null : $this->getUploadRootDir().'/'.$this->path;}公共函数 getWebPath(){返回 null === $this->path ?null : $this->getUploadDir().'/'.$this->path;}受保护的函数 getUploadRootDir(){返回 __DIR__.'/../../../../web/'.$this->getUploadDir();}受保护的函数 getUploadDir(){返回上传/img"；}公共函数上传(){if (null === $this->file) {返回;} 别的 {$this->path = $this->firstName.'_'.$this->lastName.'_'.sha1(uniqid(mt_rand(), true)).'.'.$this->文件->guessExtension();}$this->file->move($this->getUploadRootDir(), $this->path);$this->file = null;}公共函数 getPath(){返回 $this->getWebPath();}}

用户类型:

$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:

<块引用>

在/home/user/www/sf2/vendor/symfony/symfony/src/Symfony/Component/Security/Core/Authentication/Token/AbstractToken.php在第 155 行

<代码>152.$this->角色，153. $this-> 属性154.)155.);}/**

<块引用>

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

                    'required' => false,
                ))
            ;

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 :

in /home/user/www/sf2/vendor/symfony/symfony/src/Symfony/Component/Security/Core/Authentication/Token/AbstractToken.php at line 155

152.                $this->roles,
153.                $this->attributes
154.            )
155.        );
    }
    /**

at serialize (array(object(User), true, array(object(Role)), array())) in /home/kevin/www/sf2/vendor/symfony/symfony/src/Symfony/Component/Security/Core/Authentication/Token/AbstractToken.php at line 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
