Php Symfony 5约束验证：自定义错误消息

我想使用SF 4.3上发布的新NotConvertized密码：

我已经在验证中设置了它。yaml如下：

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ConstraintPasswordValidator.php上使用它：

<?php

namespace 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
    }
}

---

您可以在validation.yaml上传递
消息
选项

App\Entity\User:
    properties:
        plainPassword:
            - Symfony\Component\Validator\Constraints\NotCompromisedPassword:
                message: "You error message"

但是，如果要将约束验证到验证器中，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;
        }
    }
}

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;
        }
    }
}
