Question

伙计们我是Symfony 4的新手，

这是我的security.yaml，我的目的是从数据库登录加载用户

security:
   encoders:
       App\Entity\Login: 
          algorithm: bcrypt

providers:
    db_provider:
        entity:
            class: App\Entity\Login
            property: username

firewalls:
    dev:
        pattern: ^/(_(profiler|wdt)|css|images|js)/
        security: false
    main:
        provider: db_provider
        anonymous: ~
        form_login:
            login_path: login
            check_path: login
            default_target_path: postlogin

这是我的实体

class Login
{
/**
 * @ORM\Id()
 * @ORM\GeneratedValue()
 * @ORM\Column(type="integer")
 */
private $id;

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

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

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

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

public function getUsername(): ?string
{
    return $this->username;
}

public function setUsername(string $username): self
{
    $this->username = $username;

    return $this;
}

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

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

    return $this;
}

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

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

    return $this;
}

}

这是完整的错误

Answer 1

您的“登录”实体必须实现UserInterface或AdvancedUserInterface

像：

use Symfony\Component\Security\Core\User\AdvancedUserInterface;

class User implements AdvancedUserInterface, \Serializable
{
....
}

用户提供程序必须返回UserInterface对象，SYmfony 4登录错误
