【问题描述】：
我在 symfony 上实现 JWT 令牌时遇到了一个大问题。 我已经使用 JWT 令牌，但我还需要将用户角色添加到令牌信息中。我正在使用侦听器 (JWTCreatedListener) 执行此操作：
public function onJWTCreated(JWTCreatedEvent $event)
{
$request = $this->requestStack->getCurrentRequest();
$payload = $event->getData();
$payload['ip'] = $request->getClientIp();
$payload['roles'] = $event->getUser()->getRoles();
$event->setData($payload);
}
我以这种方式实现了Role.php（AppBundle/Entity/Role.php）：
<?php
namespace AppBundle\Entity;
use Symfony\Component\Security\Core\Role\RoleInterface;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Table(name="acme_role")
* @ORM\Entity()
*/
class Role implements RoleInterface
{
/**
* @ORM\Column(name="id", type="integer")
* @ORM\Id()
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @ORM\Column(name="name", type="string", length=30)
*/
private $name;
/**
* @ORM\Column(name="role", type="string", length=20, unique=true)
*/
private $role;
/**
* @ORM\ManyToMany(targetEntity="User", mappedBy="roles")
*/
private $users;
public function __construct()
{
$this->users = new ArrayCollection();
}
/**
* @see RoleInterface
*/
public function getRole()
{
return $this->role;
}
// ... getters and setters for each property
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set name
*
* @param string $name
*
* @return Role
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* @return string
*/
public function getName()
{
return $this->name;
}
/**
* Set role
*
* @param string $role
*
* @return Role
*/
public function setRole($role)
{
$this->role = $role;
return $this;
}
/**
* Add user
*
* @param \AppBundle\Entity\User $user
*
* @return Role
*/
public function addUser(\AppBundle\Entity\User $user)
{
$this->users[] = $user;
return $this;
}
/**
* Remove user
*
* @param \AppBundle\Entity\User $user
*/
public function removeUser(\AppBundle\Entity\User $user)
{
$this->users->removeElement($user);
}
/**
* Get users
*
* @return \Doctrine\Common\Collections\Collection
*/
public function getUsers()
{
return $this->users;
}
}
还有我的用户类：
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\AdvancedUserInterface;
use Doctrine\Common\Collections\ArrayCollection;
/**
* @ORM\Table(name="users")
* @ORM\Entity
*/
class User implements AdvancedUserInterface, \Serializable
{
/**
* @ORM\Column(type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @ORM\Column(type="string", length=25, unique=true)
*/
private $username;
/**
* @ORM\Column(type="string", length=500)
*/
private $password;
/**
* @ORM\Column(name="is_active", type="boolean")
*/
private $isActive;
/**
* @ORM\ManyToMany(targetEntity="Role", inversedBy="users")
*
*/
private $roles;
public function __construct($username)
{
$this->isActive = true;
$this->username = $username;
$this->roles = new ArrayCollection();
}
public function getUsername()
{
return $this->username;
}
public function getSalt()
{
return null;
}
public function getPassword()
{
return $this->password;
}
public function setPassword($password)
{
$this->password = $password;
}
public function getRoles()
{
return $this->roles->toArray();
}
public function eraseCredentials()
{
}
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set username
*
* @param string $username
*
* @return User
*/
public function setUsername($username)
{
$this->username = $username;
return $this;
}
/**
* Set isActive
*
* @param boolean $isActive
*
* @return User
*/
public function setIsActive($isActive)
{
$this->isActive = $isActive;
return $this;
}
/**
* Get isActive
*
* @return boolean
*/
public function getIsActive()
{
return $this->isActive;
}
/**
* Add role
*
* @param \AppBundle\Entity\Role $role
*
* @return User
*/
public function addRole(\AppBundle\Entity\Role $role)
{
$this->roles[] = $role;
return $this;
}
/**
* Remove role
*
* @param \AppBundle\Entity\Role $role
*/
public function removeRole(\AppBundle\Entity\Role $role)
{
$this->roles->removeElement($role);
}
public function isAccountNonExpired()
{
return true;
}
public function isAccountNonLocked()
{
return true;
}
public function isCredentialsNonExpired()
{
return true;
}
public function isEnabled()
{
return $this->isActive;
}
// serialize and unserialize must be updated - see below
public function serialize()
{
return serialize(array(
// ...
$this->isActive
));
}
public function unserialize($serialized)
{
list (
// ...
$this->isActive
) = unserialize($serialized);
}
}
问题是getRole()这个方法总是返回空。
这是我的数据库数据：
[users]
id username password is_active
1 abriceno $2y$13$NW6uNOKJGUQTSXirej4HKOwIa6mWzYqFxzz1ppWQjyp... 1
[acme_role]
id name role
1 admin ROLE_ADMIN
[user_role]
user_id user_role
1 1
另外，我尝试使用教义从控制器测试中调用数据：
public function indexAction(Request $request)
{
$repository = $this->getDoctrine()->getRepository('AppBundle:User');
$user = $repository->findOneByusername('abriceno');
$username = $user->getUsername();
$roles = $user->getRoles();
$arr = array(
'username' => $user->getUsername(),
'password' => $user->getPassword(),
'roles' => $user->getRoles()
);
return new JsonResponse($arr);
返回：
{"username":"abriceno","password":"$2y$13$NW6uNOKJGUQTSXirej4HKOwIa6mWzYqFxzz1ppWQjypQJLIgUGJ.m","roles":[{}]}
我很绝望...感谢您提供给我的所有帮助。

如果我执行 print_r($role) 这将打印一个 huuuuuge 值列表：
array(1) { [0]=> object(AppBundle\Entity\Role)#624 (4) { ["id":"AppBundle\Entity\Role":private]=> int(1) ["name":"AppBundle\Entity\Role":private]=> string(5) "admin" ["role":"AppBundle\Entity\Role":private]=> string(10) "ROLE_ADMIN" ["users":"AppBundle\Entity\Role":private]=> object(Doctrine\ORM\PersistentCollection)#626 (9) { ["snapshot":"Doctrine\ORM\PersistentCollection":private]=> array(0) { } ["owner":"Doctrine\ORM\PersistentCollection":private]=> *RECURSION*
...而且继续...很奇怪！
