Question

这是我的情况：

我有一个Article实体。每个文章都有一个所有者（User）。用户可以拥有许多文章。用户可以通过API发布文章。

我希望根据Bearer令牌自动设置商品的user_id列（我正在使用JWT auth）。

我在任何地方都找不到有关如何执行此操作的文档。有人可以帮忙实现此目标吗？

注意：我正在寻找可以避免在Symfony中使用其他扩展名（或控制器）的解决方案。我相信Api Platform应该可以使用内置技术来实现这一目标，但是我可能是错的。

这是我的实体：

Answer 1

应该可以使用EventListener：https://api-platform.com/docs/core/events

有了这些，您无需新控制器即可直接进入ApiPlatform进程的内部进程。非常适合您的用例。

一个实现可能看起来像这样：

<?php
// api/src/EventSubscriber/AddOwnerToArticleSubscriber.php

namespace App\EventSubscriber;

use ApiPlatform\Core\EventListener\EventPriorities;
use App\Entity\Article;
use App\Entity\User;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpKernel\Event\GetResponseForControllerResultEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;

final class AddOwnerToArticleSubscriber implements EventSubscriberInterface
{

    /**
     * @var TokenStorageInterface
     */
    private $tokenStorage;

    public function __construct(TokenStorageInterface $tokenStorage)
    {

        $this->tokenStorage = $tokenStorage;
    }

    public static function getSubscribedEvents()
    {
        return [
            KernelEvents::VIEW => ['attachOwner', EventPriorities::PRE_WRITE],
        ];
    }

    public function attachOwner(GetResponseForControllerResultEvent $event)
    {
        $article = $event->getControllerResult();
        $method = $event->getRequest()->getMethod();

        if (!$article instanceof Article || Request::METHOD_POST !== $method) {

            // Only handle Article entities (Event is called on any Api entity)
            return;
        }

        // maybe these extra null checks are not even needed
        $token = $this->tokenStorage->getToken();
        if (!$token) {
            return;
        }

        $owner = $token->getUser();
        if (!$owner instanceof User) {
            return;
        }


        // Attach the user to the not yet persisted Article
        $article->setUser($owner);

    }
}

Answer 2

您可以创建一个名为Base的实体，并且可以在此类中具有一些属性，例如“ createBy”，“ modifyBy”，“ createAt”，“ modifyAt”，“ status”。

<?php
   
namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Serializer\Annotation\Groups;

/**
 * @ORM\MappedSuperclass()
 */
class Base implements PublishedInfoEntityInterface
{

    /**
     * @ORM\Column(type="datetime", nullable=true)
     */
    private $createdAt;

    /**
     * @ORM\Column(type="datetime", nullable=true)
     */
    private $modifiedAt;

    /**
     * @ORM\ManyToOne(targetEntity="User")
     * @ORM\JoinColumn(nullable=true)
     */
    private $createdBy;

    /**
     * @ORM\ManyToOne(targetEntity="User")
     * @ORM\JoinColumn(nullable=true)
     */
    private $modifiedBy;

    /**
     * @ORM\Column(type="integer", nullable=true, length=2)
     */
    private $status;

    public function getCreatedAt()
    {
        return $this->createdAt;
    }

    public function setCreatedAt(\DateTimeInterface $createdAt): PublishedInfoEntityInterface
    {
        $this->createdAt = $createdAt;

        return $this;
    }

    public function getModifiedAt()
    {
        return $this->modifiedAt;
    }

    public function setModifiedAt(\DateTimeInterface $modifiedAt): PublishedInfoEntityInterface
    {
        $this->modifiedAt = $modifiedAt;

        return $this;
    }

    /**
     * @return User
     */
    public function getCreatedBy()
    {
        return $this->createdBy;
    }

    /**
     * @param User $createdBy
     * @return Base
     */
    public function setCreatedBy($createdBy): self
    {
        $this->createdBy = $createdBy;
        return $this;
    }

    /**
     * @return User
     */
    public function getModifiedBy()
    {
        return $this->modifiedBy;
    }

    /**
     * @param User $modifiedBy
     * @return Base
     */
    public function setModifiedBy($modifiedBy): self
    {
        $this->modifiedBy = $modifiedBy;
        return $this;
    }

    /**
     * @return int
     */
    public function getStatus()
    {
        return $this->status;
    }

    /**
     * @param integer $status
     */
    public function setStatus($status): void
    {
        $this->status = $status;
        return $this;
    }
}

创建用于设置自动createBy的订户类，并像此代码一样修改ModifyBy

<?php

namespace App\EventSubscriber;

use ApiPlatform\Core\EventListener\EventPriorities;
use App\Entity\Base;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpKernel\Event\ViewEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\Security\Core\Security;

class AuthoredEntitySubscriber implements EventSubscriberInterface
{
    private $entityManager;
    /**
     * @var Security
     */
    private $security;

    public function __construct(EntityManagerInterface $entityManager,Security $security)
    {
        $this->entityManager = $entityManager;
        $this->security = $security;
    }

    public static function getSubscribedEvents()
    {
        return [KernelEvents::VIEW => ['setAuthor', EventPriorities::PRE_WRITE]];
    }

    public function setAuthor(ViewEvent $event)
    {
        $entity = $event->getControllerResult();
        $method = $event->getRequest()->getMethod();
        $role = $this->security->getToken()->getRoleNames();

        if (!$entity instanceof Base || !in_array($method, [Request::METHOD_POST, Request::METHOD_PUT]) || !$role) {
            return;
        }

         $entity->setModifiedBy($this->security->getUser());

         if (Request::METHOD_POST === $method) {
             $entity->setCreatedBy($this->security->getUser());
         }
    }
}

如果要添加自动createAt和ModifyAt，则必须为createAt和ModifyAt创建一个名为PublishedInfoEntityInterface的接口类，并且该类编写以下代码：

<?php

namespace App\Entity;

interface PublishedInfoEntityInterface
{
    public function setCreatedAt(\DateTimeInterface $dateTime): PublishedInfoEntityInterface;

    public function setModifiedAt(\DateTimeInterface $dateTime): PublishedInfoEntityInterface;
}

并创建用于自动填充的订户，如下所示：

<?php

namespace App\EventSubscriber;


use ApiPlatform\Core\EventListener\EventPriorities;
use App\Entity\PublishedInfoEntityInterface;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpKernel\Event\ViewEvent;
use Symfony\Component\HttpKernel\KernelEvents;

class PublishedInfoEntitySubscriber implements EventSubscriberInterface
{

    public static function getSubscribedEvents()
    {
        return [KernelEvents::VIEW => ['setDataTime', EventPriorities::PRE_WRITE]];
    }

    public function setDataTime(ViewEvent $event)
    {
        $entity = $event->getControllerResult();
        $method = $event->getRequest()->getMethod();

        if (!$entity instanceof PublishedInfoEntityInterface || !in_array($method, [Request::METHOD_POST, Request::METHOD_PUT])) {
            return;
        }

        $entity->setCreatedAt(new \DateTime());

        if (Request::METHOD_POST === $method){
            $entity->setModifiedAt(new \DateTime());
        }
    }
}

最后，每个想要拥有这些属性的类都只是像这样扩展该类

class User extends Base implements UserInterface

并创建迁移

Answer 3

另一种方法是使用学说实体监听器。


class SetUserListener
{

    private Security $security;

    public function __construct(Security $security)
    {
        $this->security = $security;
    }

    public function prePersist($obj)
    {
        if (!is_a($obj, Timer::class) &&
            !is_a($obj, DailySummary::class) &&
            !is_a($obj, Task::class)
        ) {
            return;
        }
        if ($obj->getUser()) {
            return;
        }
        if ($this->security->getUser()) {
            $obj->setUser($this->security->getUser());
        }
    }
}

在服务中连接实体侦听器

App\Doctrine\SetUserListener:
        tags: [ doctrine.orm.entity_listener ]

就我而言，我使用 Gedmo 包和 Blameable 注释。我创建了一个特征而不是像下面这样的映射超类：

<?php

namespace App\ORM\Traits;

use App\Entity\User;
use Doctrine\ORM\Mapping as ORM;
use Gedmo\Mapping\Annotation as Gedmo;

trait OwnerTrait
{
    /**
     * @var User|null
     * @ORM\ManyToOne(targetEntity="App\Entity\User")
     * @ORM\JoinColumn(name="created_by", referencedColumnName="id", nullable=true, onDelete="SET NULL")
     *
     * @Gedmo\Blameable(on="create")
     */
    protected ?User $createdBy;

    /**
     * @var User|null
     * @ORM\ManyToOne(targetEntity="App\Entity\User")
     * @ORM\JoinColumn(name="updated_by", referencedColumnName="id", nullable=true, onDelete="SET NULL")
     *
     * @Gedmo\Blameable(on="update")
     */
    protected ?User $updatedBy;

    /**
     * Set createdBy
     * @param User|null $createdBy
     * @return $this
     */
    public function setCreatedBy(?User $createdBy)
    {
        $this->createdBy = $createdBy;

        return $this;
    }

    /**
     * Returns the user who create the object
     * @return User|null
     */
    public function getCreatedBy(): ?User
    {
        return $this->createdBy;
    }

    /**
     * Set updatedBy
     * @param User|null $updatedBy
     * @return $this
     */
    public function setUpdatedBy(?User $updatedBy)
    {
        $this->updatedBy = $updatedBy;

        return $this;
    }

    /**
     * Returns user who is the last to modify object
     * @return User|null
     */
    public function getUpdatedBy(): ?User
    {
        return $this->updatedBy;
    }
}

在实体上

<?php

class Article
{
   use OwnerTrait;
}

使用Api平台，自动将用户分配给对象（OneToMany）
