用户应用程序实体用户没有用户提供程序您的用户提供程序的supportsClass()方法不应该为这个类名返回true吗？

Question

我创建了一个电子邮件/密码登录表单，但遇到了一个非常令人失望的问题:(

首先，这是我得到的（我使用的是 Symfony 4.4.18）：

&这些是我的代码：

这是用户实体（添加了supportsClass()方法）App\Entity\User：

<?php

namespace App\Entity;

use App\Repository\UserRepository;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\Security\Core\User\UserInterface;

/**
 * @ORM\Entity(repositoryClass=UserRepository::class)
 */
class User implements UserInterface, \Serializable
{
    /**
     * @ORM\Id
     * @ORM\GeneratedValue
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\Column(type="string", length=255, unique=true)
     */
    private $first_name;

    /**
     * @ORM\Column(type="string", length=255)
     */
    private $last_name;

    /**
     * @ORM\Column(type="string", length=255, unique=true)
     * @Assert\Regex(pattern="/^\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/", message="Enter Valid Email")
     */
    private $email;

    /**
     * @ORM\Column(type="string", length=11)
     */
    private $phone_number;

    /**
     * @ORM\Column(type="string", length=255)
     * @Assert\NotBlank(message="New password can not be blank.")
     * @Assert\Regex(pattern="/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{8,}$/", message="Minimum eight characters, at least one uppercase letter, one lowercase letter, one number and one special character")
     */
    private $password;

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

    public function getFirstName(): ?string
    {
        return $this->first_name;
    }

        return $this;
    }

    {
        return $this->last_name;
    }

    public function setLastName(string $last_name): self

        $this->last_name = $last_name;

        return $this;
    }

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

    public function setEmail(string $email): self
    {
        $this->email = $email;

        return $this;
    }

    public function getPhoneNumber(): ?string
    {
        return $this->phone_number;
    }

    public function setPhoneNumber(string $phone_number): self
    {
        $this->phone_number = $phone_number;

        return $this;
    }

    public function getPassword(): ?string
    {
        return $this->password;
    }

    public function setPassword(string $password): self
    {
        $this->password = $password;

        return $this;
    }

    public function getRoles(): array
    {
        return [
            'ROLE_USER'
        ];
    }

    /**

    public function getSalt()
    {
        // TODO: Implement getSalt() method.
    }

    /**

     */
    public function getUsername()
    {
        // TODO: Implement getUsername() method.
    }

    /**
     * @inheritDoc
     */
    public function eraseCredentials()
    {
        // TODO: Implement eraseCredentials() method.
    }

    /**
     * @inheritDoc
     */
    public function serialize()
    {
        return serialize([
            $this->id,
            $this->first_name,
            $this->last_name,
            $this->email,
            $this->phone_number,
            $this->password,
        ]);
    }

    /**
     * @inheritDoc
     */
    public function unserialize($serialized)
    {
        list(
            $this->id,
            $this->first_name,
            $this->last_name,
            $this->email,
            $this->phone_number,
            $this->password,
            ) = unserialize($serialized, ['allowed_classes' => false]);
    }

    public function supportsClass($class)
    {
        return $class === User::class;
    }

}

我对supportsClass()一无所知。 之前尝试过使用自定义用户提供程序的用户存储库，但没有成功

Answer 1

您这里有错字：

APP\Entity\User -> App\Entity\User

Answer 2

你必须转到 security.yaml 然后更改 APP 实体\用户 ---> 到应用程序\实体\用户
