Symfony 6和EasyAdmin 4：哈希密码-DEV365 开发者社区

*封面图像最初是由geralt进行的，并以非常感谢。

概括

使用EasyAdmin捆绑包，您可以轻松创建管理面板：

好吧，对于用户实体，鉴于它具有密码字段，您必须在存储安全之前先进行哈希。

这篇文章显示了如何使用EasyAdmin实施。

环境

Alpine Linux 3.16 (on Docker)
PHP 8.1
symfony 6.1
MariaDB 10.9

如何哈希密码

源代码

这是一个例子。
像这样修改src/Controller/Admin/UserCrudController.php：

<?php

namespace App\Controller\Admin;

use App\Entity\User;
use EasyCorp\Bundle\EasyAdminBundle\Config\{Action, Actions, Crud, KeyValueStore};
use EasyCorp\Bundle\EasyAdminBundle\Context\AdminContext;
use EasyCorp\Bundle\EasyAdminBundle\Controller\AbstractCrudController;
use EasyCorp\Bundle\EasyAdminBundle\Dto\EntityDto;
use EasyCorp\Bundle\EasyAdminBundle\Field\{IdField, EmailField, TextField};
use Symfony\Component\Form\Extension\Core\Type\{PasswordType, RepeatedType};
use Symfony\Component\Form\{FormBuilderInterface, FormEvent, FormEvents};
use Symfony\Component\PasswordHasher\Hasher\UserPasswordHasherInterface;

class UserCrudController extends AbstractCrudController
{
    public function __construct(
        public UserPasswordHasherInterface $userPasswordHasher
    ) {}

    public static function getEntityFqcn(): string
    {
        return User::class;
    }

    public function configureActions(Actions $actions): Actions
    {
        return $actions
            ->add(Crud::PAGE_EDIT, Action::INDEX)
            ->add(Crud::PAGE_INDEX, Action::DETAIL)
            ->add(Crud::PAGE_EDIT, Action::DETAIL)
            ;
    }

    public function configureFields(string $pageName): iterable
    {
        $fields = [
            IdField::new('id')->hideOnForm(),
            EmailField::new('email'),
        ];

        $password = TextField::new('password')
            ->setFormType(RepeatedType::class)
            ->setFormTypeOptions([
                'type' => PasswordType::class,
                'first_options' => ['label' => 'Password'],
                'second_options' => ['label' => '(Repeat)'],
                'mapped' => false,
            ])
            ->setRequired($pageName === Crud::PAGE_NEW)
            ->onlyOnForms()
            ;
        $fields[] = $password;

        return $fields;
    }

    public function createNewFormBuilder(EntityDto $entityDto, KeyValueStore $formOptions, AdminContext $context): FormBuilderInterface
    {
        $formBuilder = parent::createNewFormBuilder($entityDto, $formOptions, $context);
        return $this->addPasswordEventListener($formBuilder);
    }

    public function createEditFormBuilder(EntityDto $entityDto, KeyValueStore $formOptions, AdminContext $context): FormBuilderInterface
    {
        $formBuilder = parent::createEditFormBuilder($entityDto, $formOptions, $context);
        return $this->addPasswordEventListener($formBuilder);
    }

    private function addPasswordEventListener(FormBuilderInterface $formBuilder): FormBuilderInterface
    {
        return $formBuilder->addEventListener(FormEvents::POST_SUBMIT, $this->hashPassword());
    }

    private function hashPassword() {
        return function($event) {
            $form = $event->getForm();
            if (!$form->isValid()) {
                return;
            }
            $password = $form->get('password')->getData();
            if ($password === null) {
                return;
            }

            $hash = $this->userPasswordHasher->hashPassword($this->getUser(), $password);
            $form->getData()->setPassword($hash);
        };
    }
}

描述

我会将其分解为几个部分。

Constructor Property Promotion

此样式是有效的，因为PHP 8.0。

    public function __construct(
        public UserPasswordHasherInterface $userPasswordHasher
    ) {}

当您的php版本在其之前，请按照下面的方式写下：

    private $userPasswordHasher;

    public function __construct(
        UserPasswordHasherInterface $userPasswordHasher
    ) {
        $this->userPasswordHasher = $userPasswordHasher;
    }

添加菜单

这是可选的。菜单被添加到索引页面并编辑。

    public function configureActions(Actions $actions): Actions
    {
        return $actions
            ->add(Crud::PAGE_EDIT, Action::INDEX)
            ->add(Crud::PAGE_INDEX, Action::DETAIL)
            ->add(Crud::PAGE_EDIT, Action::DETAIL)
            ;
    }

生成密码字段

configureFields是configure the fields to display的EasyAdmin的功能之一。
在这里，密码字段定义为passwordType和repotedType。另外，作为一个unmapped field，可以防止在设置null以不更改密码的情况下进行验证例外。

    public function configureFields(string $pageName): iterable
    {
        $fields = [
            IdField::new('id')->hideOnForm(),
            EmailField::new('email'),
        ];

        $password = TextField::new('password')
            ->setFormType(RepeatedType::class)
            ->setFormTypeOptions([
                'type' => PasswordType::class,
                'first_options' => ['label' => 'Password'],
                'second_options' => ['label' => '(Repeat)'],
                'mapped' => false,
            ])
            ->setRequired($pageName === Crud::PAGE_NEW)
            ->onlyOnForms()
            ;
        $fields[] = $password;

        return $fields;
    }

处理事件

在这里，Symfony表单事件与EasyAdmin事件处理程序一起使用。这是因为到目前为止EasyAdmin's events不支持处理形式验证。

    public function createNewFormBuilder(EntityDto $entityDto, KeyValueStore $formOptions, AdminContext $context): FormBuilderInterface
    {
        $formBuilder = parent::createNewFormBuilder($entityDto, $formOptions, $context);
        return $this->addPasswordEventListener($formBuilder);
    }

    public function createEditFormBuilder(EntityDto $entityDto, KeyValueStore $formOptions, AdminContext $context): FormBuilderInterface
    {
        $formBuilder = parent::createEditFormBuilder($entityDto, $formOptions, $context);
        return $this->addPasswordEventListener($formBuilder);
    }

    private function addPasswordEventListener(FormBuilderInterface $formBuilder): FormBuilderInterface
    {
        return $formBuilder->addEventListener(FormEvents::POST_SUBMIT, $this->hashPassword());
    }

哈希密码

这是Symfony的PasswordHasher的Hashing密码的关键部分。
当未输入密码时，跳过字段。
hash hash，并将字段添加到实体datað

    private function hashPassword() {
        return function($event) {
            $form = $event->getForm();
            if (!$form->isValid()) {
                return;
            }
            $password = $form->get('password')->getData();
            if ($password === null) {
                return;
            }

            $hash = $this->userPasswordHasher->hashPassword($this->getUser(), $password);
            $form->getData()->setPassword($hash);
        };
    }

就是这样。
