Php 在Symfony中找不到对null上的成员函数isPasswordValid（）调用的解决方案

当我尝试登录到注册用户时，我不能超过此错误。 我的授权人

我是Symfony的乞丐我不止一次读过Symfony安全章节。我一定错过了什么。如果有人能帮我在AUAuthenticator中使用这个，而不是这个，那就太好了：

public function checkCredentials($credentials, UserInterface $user)
{
return $this->passwordEncoder->isPasswordValid($user->getPassword(), $credentials['password'],$user->getSalt());
}

providers:
    users_in_memory: { memory: null }

    main:
        anonymous: false
        lazy: true
        provider: users_in_memory
        guard:
            authenticators:
                - App\Security\UserLoginAuthentificatorAuthenticator

使用以下命令：

public function checkCredentials($credentials, UserInterface $user)
{
return $this->passwordEncoder->isPasswordValid($user, $credentials['password']);
}

providers:
    app_user_provider:
        entity:
            class: App\Entity\User
            property: email

    main:
        anonymous: true
        lazy: true
        provider: app_user_provider
        guard:
            authenticators:
                - App\Security\UserAuthenticator

---

在security.yaml中，而不是在该文件中：

public function checkCredentials($credentials, UserInterface $user)
{
return $this->passwordEncoder->isPasswordValid($user->getPassword(), $credentials['password'],$user->getSalt());
}

providers:
    users_in_memory: { memory: null }

    main:
        anonymous: false
        lazy: true
        provider: users_in_memory
        guard:
            authenticators:
                - App\Security\UserLoginAuthentificatorAuthenticator

使用以下命令：

public function checkCredentials($credentials, UserInterface $user)
{
return $this->passwordEncoder->isPasswordValid($user, $credentials['password']);
}

providers:
    app_user_provider:
        entity:
            class: App\Entity\User
            property: email

    main:
        anonymous: true
        lazy: true
        provider: app_user_provider
        guard:
            authenticators:
                - App\Security\UserAuthenticator

---

而不是这个：

public function checkCredentials($credentials, UserInterface $user)
{
return $this->passwordEncoder->isPasswordValid($user->getPassword(), $credentials['password'],$user->getSalt());
}

providers:
    users_in_memory: { memory: null }

    main:
        anonymous: false
        lazy: true
        provider: users_in_memory
        guard:
            authenticators:
                - App\Security\UserLoginAuthentificatorAuthenticator

使用以下命令：

public function checkCredentials($credentials, UserInterface $user)
{
return $this->passwordEncoder->isPasswordValid($user, $credentials['password']);
}

providers:
    app_user_provider:
        entity:
            class: App\Entity\User
            property: email

    main:
        anonymous: true
        lazy: true
        provider: app_user_provider
        guard:
            authenticators:
                - App\Security\UserAuthenticator

并在控制器中添加：

    $this->passwordEncoder = $passwordEncoder;

之后：

    $this->csrfTokenManager = $csrfTokenManager;

像这样：

public function __construct(EntityManagerInterface $entityManager, UrlGeneratorInterface $urlGenerator, CsrfTokenManagerInterface $csrfTokenManager, UserPasswordEncoderInterface $passwordEncoder)
{
    $this->entityManager = $entityManager;
    $this->urlGenerator = $urlGenerator;
    $this->csrfTokenManager = $csrfTokenManager;
    $this->passwordEncoder = $passwordEncoder;
}

您似乎忘记在验证器的构造函数中分配

$this->passwordEncoder=$passwordEncoder

。感谢您的帮助意味着您正在使用新的验证器功能。它与保护身份验证器不兼容。即使您有了工作，也应该重新启动一个项目，决定是否要使用新的身份验证系统，然后再次运行make:auth。@Cerad，您说得对。谢谢您的帮助，就这样。我以前尝试过这些修改，但我没有向好的提供者寻址，也没有分配$passwordEncoder。我必须删除security.yalm中的anonymous=true。我在告诉别人没有使用匿名时出错，我不得不删除它。@如果这个答案解决了你的问题，或者对找到你的解决方案最有帮助，菲尔就接受这个答案
