Security 在symfony身份验证中取消序列化用户数据时出错

我的第一个问题。我在上面坐了几个小时，找不到解决方案： 当用户成功地在数据库中找到时，我猜symfony会尝试将其数据序列化到会话中，错误就会弹出

Notice: unserialize(): Error at offset 37 of 49 bytes in G:\cebuland\vendor\symfony\symfony\src\Symfony\Component\Security\Core\Authentication\Token\AbstractToken.php line 163

导致登录过程出错

用户实体：

/**
 * @ORM\Entity
 * @ORM\Table(name="User")
 */
class User implements AdvancedUserInterface, \Serializable{
...
    /**
     * @ORM\ManyToMany(targetEntity="Role", inversedBy="user")
     * @var $role Doctrine\Common\Collections\ArrayCollection
     */
    private $role;
...
    public function getRoles() {
        return $this->role->toArray();
    }
...
    public function serialize() {
        serialize(array(
            $this->id, 
            $this->name,
            $this->password,
            $this->created,
            $this->last_activity,
            $this->ghost,
            $this->role
        ));
    }
    public function unserialize($serialized) {
        list(
            $this->id, 
            $this->name,
            $this->password,
            $this->created,
            $this->last_activity,
            $this->ghost,
            $this->role
        ) = unserialize($serialized);
    }

角色的实体非常相似

以及security.yml配置文件：

security:
    providers:
        users:
            entity: {class: ApplicationMainBundle:User, property: name}
    encoders: 
        Application\MainBundle\Entity\User:
            #plain just for testing
            algorithm: plaintext 
    firewalls:
        secured_area:
            logout: 
                path: /logout
            pattern:   ^/
            anonymous: ~
            form_login:
                login_path: /login
                check_path: /login_check
    access_control:
        - { path: ^/admin/, roles: ROLE_ADMINISTRATOR}

在互联网上找不到任何线索

您的User:：serialize方法不返回序列化字符串，但它应该

@MarekLewandowski您在这里做了什么使其工作？你能发布一些代码吗？他正在给函数serialize（）添加返回
