Symfony 5 约束验证：自定义错误消息

Question

我想使用SF 4.3上发布的新不承诺密码：https://symfony.com/blog/new-in-symfony-4-3-compromised-password-validator我已经在我的验证.yaml上设置了它，如下所示：App\Entity\User:    constraints:        - App\Validator\Constraints\ConstraintPassword: ~    properties:        plainPassword:            - Symfony\Component\Validator\Constraints\NotCompromisedPassword: ~它可以工作，但我想自定义错误消息，例如，直接在我的约束密码验证器上使用它.php：<?phpnamespace App\Validator\Constraints;use App\Entity\User;use Symfony\Component\Validator\Constraint;use Symfony\Component\Validator\Constraints\NotCompromisedPassword;use Symfony\Component\Validator\ConstraintValidator;class ConstraintPasswordValidator extends ConstraintValidator{    /**     * @param User $user     * @param Constraint $constraint     */    public function validate($user, Constraint $constraint)    {        if (strlen($user->getPlainPassword()) < 8 || strlen($user->getPlainPassword() < 35)) {            $this->context->buildViolation($constraint->lengthError)                ->addViolation();        }        // Doing something like that        $notCompromised = new NotCompromisedPassword();        $notCompromised->message = "My custom error message";       //Then, build the violation if password leaked    }}也许它需要在我的约束密码中实例化和自定义.php？但我不知道如何<?phpnamespace App\Validator\Constraints;use Symfony\Component\Validator\Constraint;class ConstraintPassword extends Constraint{    public $lengthError = 'Erreur : La longueur du mot de passe doit être comprise entre 8 et 35 caractères';    public function validatedBy()    {        return \get_class($this).'Validator';    }    public function getTargets()    {        return self::CLASS_CONSTRAINT;    }}

您可以在验证上传递该选项。message

App\Entity\User:

    properties:

        plainPassword:

            - Symfony\Component\Validator\Constraints\NotCompromisedPassword:

                message: "You error message"

但是，如果要将约束验证为验证器，则可以使用：

class MyValidator extends ConstraintValidator

{

    public function validate($value, Constraint $chain)

    {

        // Previous check...

        $groups = $this->context->getGroup();

        $violations = $this->context->getViolations();

        $current = $violations->count();

        // Execute the new constraint

        $this->context->getValidator()

            ->inContext($this->context)

            ->validate($value, new MyOtherConstraint(), $groups);

        // Check if the constraint has failed

        if ($violations->count() !== $current) {

            return;

        }

    }

}
