php - Symfony 4.4 + scheb/2fa：自定义代码生成器和邮件程序

Question

我正在尝试遵循此文档，但 yaml 配置会引发一些错误。我对 Symfony 的了解还不够，无法理解我做错了什么。 https://github.com/scheb/2fa/blob/5.x/doc/providers/email.md

服务.yaml：

https://symfony.com/doc/current/best_practices/configuration.html#application-related-configuration
parameters:
    uploads_path: '/uploads/files/'
services:
    # default configuration for services in *this* file
    _defaults:
        autowire: true      # Automatically injects dependencies in your services.
        autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.
    App\:
        resource: '../src/'
        exclude:
            - '../src/DependencyInjection/'
            - '../src/Entity/'
            - '../src/Kernel.php'
            - '../src/Tests/'
    App\Controller\:
        resource: '../src/Controller/'
        tags: ['controller.service_arguments']
    # App\Service\CodeGeneratorService:
    #     arguments: ['@markdown.parser', '@doctrine_cache.providers.my_markdown_cache']
    auth_mailer:
        # class: Scheb\TwoFactorBundle\Mailer\SymfonyAuthCodeMailer
        class: App\Mailer\MyAuthCodeMailer
    code_generator_service:
        class: App\Service\CodeGeneratorService
        # public: true
        arguments:
            # $mailer: "%scheb_two_factor.security.email.symfony_auth_code_mailer%"
            # $mailer: "%scheb_two_factor.security.email.swift_auth_code_mailer%"
            # $mailer: App\Mailer\MyAuthCodeMailer
            # $mailer: Scheb\TwoFactorBundle\Mailer\SymfonyAuthCodeMailer
            # $mailer: Scheb\TwoFactorBundle\Mailer\AuthCodeMailerInterface
            # $mailer: App\service\CodeGeneratorService
            # $mailer: "%scheb_two_factor.email.mailer%"
            $digits: "%scheb_two_factor.email.digits%"

scheb_2fa.yaml：

# See the configuration reference at https://github.com/scheb/2fa/blob/master/doc/configuration.md
scheb_two_factor:
    security_tokens:
        - Symfony\Component\Security\Guard\Token\PostAuthenticationGuardToken
    email:
        enabled: true
        sender_email: [e-mail]
        sender_name: Quezako  # Optional
        digits: 12
        code_generator: code_generator_service  # Use alternative service to generate authentication code
        mailer: auth_mailer  # Use alternative service to send the authentication code

应用\服务\CodeGeneratorService.php：

<?php
declare(strict_types=1);

namespace App\Service;

use Scheb\TwoFactorBundle\Model\PersisterInterface;
use Scheb\TwoFactorBundle\Mailer\AuthCodeMailerInterface;
use Scheb\TwoFactorBundle\Model\Email\TwoFactorInterface;
use Scheb\TwoFactorBundle\Security\TwoFactor\Provider\Email\Generator\CodeGeneratorInterface;

class CodeGeneratorService implements CodeGeneratorInterface
{
    /**
     * @var PersisterInterface
     */
    private $persister;

    /**
     * @var AuthCodeMailerInterface
     */
    private $mailer;

    /**
     * @var int
     */
    private $digits;

    public function __construct(PersisterInterface $persister, AuthCodeMailerInterface $mailer, int $digits)
    {
        $this->persister = $persister;
        $this->mailer = $mailer;
        $this->digits = $digits;
    }

    public function generateAndSend(TwoFactorInterface $user): void
    {
        $min = 10 ** ($this->digits - 1);
        $max = 10 ** $this->digits - 1;
        $code = $this->generateCode($min, $max);
        $user->setEmailAuthCode((string) $code);
        $this->persister->persist($user);
        $this->mailer->sendAuthCode($user);
    }

    public function reSend(TwoFactorInterface $user): void
    {
        $this->mailer->sendAuthCode($user);
    }

    protected function generateCode(int $min, int $max): string
    {
        return substr(md5(rand()), $min, $max); 
    }
}

我收到的各种错误消息：

无法自动装配服务“code_generator_service”：方法“App\Service\CodeGeneratorService::__construct()”的参数“$mailer”引用接口“Scheb\TwoFactorBundle\Mailer\AuthCodeMailerInterface”，但不存在此类服务。您可能应该将此接口别名为以下现有服务之一：“App\Mailer\MyAuthCodeMailer”、“auth_mailer”、“scheb_two_factor.security.email.swift_auth_code_mailer”、“scheb_two_factor.security.email.symfony_auth_code_mailer”。

您请求了一个不存在的参数“scheb_two_factor.email.mailer”。您的意思是其中之一：“scheb_two_factor.email.sender_name”、“scheb_two_factor.email.template”、“scheb_two_factor.email.digits”？

传给 App\Service\CodeGeneratorService::__construct() 的参数 2 必须实现接口 Scheb\TwoFactorBundle\Mailer\AuthCodeMailerInterface，给定字符串，在 D:\Dev\meet_the_team\var\cache\dev\Container0FXY0Rx\srcApp_KernelDevDebugContainer.php 中调用621

作者 Christian Scheb 给了我答案。

您必须配置一个服务并使用 @ 注释来引用该服务，以告诉 Symfony 使用该服务实例。 https://github.com/scheb/2fa/issues/22

services:
    # ...
    auth_mailer:
        class: App\Mailer\MyAuthCodeMailer

    code_generator_service:
        class: App\Service\CodeGeneratorService
        arguments:
            $mailer: "@auth_mailer"
            $digits: "%scheb_two_factor.email.digits%"
