Symfony 4.2 / API平台：与安全性无关的不确定性错误

时间：2019-03-25 11:56:13

标签： symfony api-platform.com symfony-4.2

我们正在使用symfony 4.2和API平台开发REST API，并且遇到了奇怪的行为。当我们发出例如在生成的端点上获取HTTP请求：我们要么获得预期的JSON响应，要么对同一请求获得500错误，看起来是随机的。有趣的是：

  • 使用我们的角度客户端体验随机错误
  • 在完全相同的URL上发出curl命令时，永远不会显示错误

这是发生错误时返回的JSON堆栈跟踪的开头：

为简单起见，我们实现了一个虚拟的AbstractGuardAuthenticator，它始终返回一个硬编码的用户，并且表现出完全相同的行为。以下是其代码，用户实体类的代码以及安全性配置的有趣之处：

<?php

namespace App\Security;

use App\Security\User\AppUser;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Security\Guard\AbstractGuardAuthenticator;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\Security\Core\Exception\AuthenticationException;
use Symfony\Component\Security\Core\User\UserProviderInterface;

class YesAuthenticator extends AbstractGuardAuthenticator
{

    public function supports(Request $request)
    {
        return true;
    }

    public function getCredentials(Request $request)
    {
        return array(
            'token' => 'sdflsdklfjsdlkfjslkdfjsldk46541qsdf',
        );
    }

    public function getUser($credentials, UserProviderInterface $userProvider)
    {
        $user = new AppUser(22, 'toto@wanadoo.fr', 'toto', 'litoto', 'tl', 'totoL', '', array(), null);
        return $user;
    }

    public function checkCredentials($credentials, UserInterface $user)
    {
        return true;
    }

    public function onAuthenticationSuccess(Request $request, TokenInterface $token, $providerKey)
    {
        return null;
    }

    public function onAuthenticationFailure(Request $request, AuthenticationException $exception)
    {
        $data = array(
            'message' => strtr($exception->getMessageKey(), $exception->getMessageData())
        );

        return new JsonResponse($data, Response::HTTP_FORBIDDEN);
    }

    public function start(Request $request, AuthenticationException $authException = null)
    {
        $data = array(
            'message' => 'Authentication Required'
        );

        return new JsonResponse($data, Response::HTTP_UNAUTHORIZED);
    }

    public function supportsRememberMe()
    {
        return false;
    }

}

用户实体类：

<?php

namespace App\Security\User;

use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Security\Core\User\EquatableInterface;

/**
 * Represents a user logged in the SSO authentication system.  
 *
 * @package App\Security\User
 */
class AppUser implements UserInterface, EquatableInterface {

    private $id;
    private $email;
    private $pseudo;
    private $avatar;
    private $surname;
    private $lastName;
    private $usePseudo;
    private $administeredProjectId;
    private $roles;

    const ADMIN_ROLE = "administrator";

    public function __construct(
        $id, $email, $surname, $lastName, $pseudo, $usePseudo, $avatar, 
        array $roles, $administeredProjectId) {

        $this->id = $id;
        $this->email = $email;
        $this->surname = $surname;
        $this->lastName = $lastName;
        $this->pseudo = $pseudo;
        $this->usePseudo = $usePseudo;
        $this->avatar = $avatar;
        $this->administeredProjectId = $administeredProjectId;
        $this->roles = $roles;
    }

    public function setId($idd) {

        $this->id = $idd;
    }

    public function getId() {

        return $this->id;
    }

    public function isAdmin() {
        return in_array(AppUser::ADMIN_ROLE, $this->roles);
    }

    public function isProjectAdmin() {
        return (!is_null($this->administeredProjectId));
    }

    public function isLuser() {
        return ( 
            !( $this->isAdmin() ) || 
            ( $this->isProjectAdmin() ) );
    }

    public function getRoles() {
        return $this->roles;
    }

    public function getSurname() {
        return $this->surname;
    }

    public function getLastName() {
        return $this->lastName;
    }

    public function getAvatar() {
        return $this->avatar;
    }

    public function getAdministeredProjectId() {
        return $this->administeredProjectId;
    }

    public function getPassword() {

        return null;
    }

    public function getSalt() {
        return null;
    }

    public function getEmail() {
        return $this->email;
    }

    public function getUsername() {
        return $this->usePseudo ? $this->pseudo : ($this->surname . ' ' . $this->lastName);
    }

    public function getPseudo() {
        return $this->pseudo;
    }

    public function eraseCredentials() {
    }

    public function isEqualTo(UserInterface $user) {
        if (!$user instanceof AppUser) {
            return false;
        }

        if ($this->username !== $user->getUsername()) {
            return false;
        }

        return true;
    }
}

security.yaml文件的提取：

security:
    providers:
        user:
            entity:
                class: App\Security\User\AppUser
                property: username
    firewalls:
        dev:
            pattern: ^/(_(profiler|wdt)|css|images|js)/
            security: true
            guard:
                authenticators:
                     - App\Security\YesAuthenticator
        main:
            anonymous: ~
            logout: ~

            guard:
                authenticators:
                    - App\Security\YesAuthenticator

这里是Web服务正在表现其行为的实体/资源的示例。没什么... 

<?php

namespace App\Entity;

use Symfony\Component\Serializer\Annotation\Groups;
use Symfony\Component\Validator\Constraints as Assert;

use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;
use ApiPlatform\Core\Annotation\ApiResource;

/**

 *     "denormalization_context"={"groups"={"write"}}},

 */
class Project
{

   /**
    * @Groups({"read"})
    * @ORM\Id
    * @ORM\GeneratedValue(strategy="IDENTITY")
    * @ORM\Column(type="integer")
    */
   private $id = null;

    /**
     * @Groups({"read"})
     * @ORM\OneToOne(targetEntity="Project")
     * @ORM\JoinColumn(name="parent_id", referencedColumnName="id")
     */
    private $parent;

   /**
    * @Assert\NotNull
    * @Groups({"read"})
    * @ORM\Column(type="string", nullable=false)
    */
   private $label = null;


   /**
    *
    * @Assert\NotNull
    * @Groups({"read"})
    * @ORM\Column(name="is_private", type="boolean", nullable=false)
    */
   private $isPrivate = true;    

    public function getId(): ?int {
        return $this->id;
    }

    public function getLabel(): ?string
    {
        return $this->label;
    }

    public function setLabel(string $label): self
    {
        $this->label = $label;

        return $this;
    }

    public function getIsPrivate(): ?bool
    {
        return $this->isPrivate;
    }

    public function setIsPrivate(bool $isPrivate): self
    {
        $this->isPrivate = $isPrivate;

        return $this;
    }

    public function getParent(): ?self
    {
        return $this->parent;
    }

    public function setParent(?self $parent): self
    {
        $this->parent = $parent;

        return $this;
    }

    public function __clone() {
        if ($this->id) {
            $this->id = null;
        }
    }

    public function __toString()
    {
        return  $this->getLabel();
    }

}

请注意，我们还有其他带有自定义数据提供程序的Web服务，该提供程序基于当前用户过滤返回的数据。以不确定的方式，对这些请求的请求有时也会失败，因为当前用户为空（而实际上确实记录了用户）。
