Symfony:必须是 Twig_Environment 的一个实例 [英] Symfony: Must be an instance of Twig_Environment

问题描述

我正在尝试为已经制作的 Symfony 应用程序实施密码重置功能.我想我快到了......但我对 Symfony 还很陌生，我仍在搜索我自己的周围......我有一个视图将 JSON 帖子发送到控制器，但它返回以下消息:

I am trying to implement a password resset feature to an already made Symfony app. I think I am almost there ... But i am pretty new to Symfony and I am still searching my self arround ... I have a view that send a JSON post to a controller but it returns the following message:

Type error: Argument 1 passed to AppBundle\Event\ForgotPasswordEventListener::__construct() must be an instance of Twig_Environment, instance of Doctrine\ORM\EntityManager given, called in /home/***/public_html/intranet/var/cache/prod/ContainerJxqbmi7/getApp_Listener_ForgotPasswordService.php on line 8

这是我的控制器:

<?php

namespace AppBundle\Event;
use CoopTilleuls\ForgotPasswordBundle\Event\ForgotPasswordEvent;

class ForgotPasswordEventListener
{

    private $twig;
    private $mailer;
    private $manager;

    public function __construct(\Twig_Environment $twig, \Swift_Mailer $mailer, \Doctrine\ORM\EntityManager $manager)
    {
        $this->templating = $twig;
        $this->mailer = $mailer;
        $this->manager=$manager;
    }

    /**
     * @param ForgotPasswordEvent $event
     */
    public function onCreateToken(ForgotPasswordEvent $event)
    {
        $passwordToken = $event->getPasswordToken();
        $user = $passwordToken->getUser();

        $swiftMessage = new \Swift_Message(
            'Reset of your password',
            $this->templating->render(
             'security/forgot-password.html.twig',
                [
                    'reset_password_url' => sprintf('http://www.example.com/forgot-password/%s', $passwordToken->getToken()),
                ]
            )
        );

        $swiftMessage->setFrom('[e-mail]');
        $swiftMessage->setTo($user->getEmail());
        $swiftMessage->setContentType('text/html');
        if (0 === $this->mailer->send($swiftMessage)) {
            throw new \RuntimeException('Unable to send email');
        }
    }

    /**
     * @param ForgotPasswordEvent $event
     */

    public function onUpdatePassword(ForgotPasswordEvent $event)
    {
        $passwordToken = $event->getPasswordToken();
        $user = $passwordToken->getUser();
        $user->setPlainPassword($event->getPassword());
        $this->manager->persist($user);
    }
}

这是我的服务:

app.listener.forgot_password:
    class: AppBundle\Event\ForgotPasswordEventListener
    arguments:
        templating: "@twig"
        mailer:     "@mailer"
        manager:    "@doctrine.orm.entity_manager"
    tags:
        - { name: kernel.event_listener, event: coop_tilleuls_forgot_password.create_token, method: onCreateToken}
        - { name: templating.helper, alias: templating, event: coop_tilleuls_forgot_password.create_token, method: onCreateToken}
        - { name: kernel.event_listener, event: coop_tilleuls_forgot_password.update_password, method: onUpdatePassword }

我真的不知道我做错了什么.感谢您的帮助！

I am really don't know what I am doing wrong. Thx for your help!

推荐答案

问题在于您的服务定义.我不确定到底是什么导致了这种情况，但似乎 Symfony 正在重新安排这些论点.有 2 种方法可以修复它.删除参数的键或通过正确使用命名属性来修复它们:

The problem is your service definition. I am not sure exactly what is causing this, but it seems that Symfony is rearranging the arguments. There are 2 ways to fix it. Either remove the keys for the arguments or fix them by properly using named properties:

app.listener.forgot_password:
    class: AppBundle\Event\ForgotPasswordEventListener
    arguments:
        - "@twig"
        - "@mailer"
        - "@doctrine.orm.entity_manager"

或者对于第二种方法:

app.listener.forgot_password:
    class: AppBundle\Event\ForgotPasswordEventListener
    arguments:
        $twig: "@twig"
        $mailer: "@mailer"
        $manager: "@doctrine.orm.entity_manager"

重要的一点是 $ 前缀，并且名称与构造函数中的参数名称相匹配.

The important bit is the $-prefix and that the name matches the argument name in the constructor.
