Question

我想在注册表单时自动设置密码。所以我使用REGISTRATION_INITIALIZE来触发事件。不幸的是它没有用。

监听器：

import numpy as np
import cv2

name = 'two_eyes1.png'

# reading an image
img = cv2.imread(name, cv2.IMREAD_COLOR)

# inverting image
img_inv = cv2.bitwise_not(img)

gray = cv2.cvtColor(img_inv, cv2.COLOR_BGR2GRAY)

ret, threshold = cv2.threshold(gray, 225, 255, cv2.THRESH_BINARY)

#----- Blob detector parameters initiation
params = cv2.SimpleBlobDetector_Params()
#change thresholds
params.minThreshold = 0;
params.maxThreshold = 255;
#filter by area
params.filterByArea = True
params.minArea = 70
# filter by cicularity
params.filterByCircularity = True
params.minCircularity = 0.1
# filter by convexity
params.filterByConvexity = True
params.minConvexity = 0.87
# filter by inertia
params.filterByInertia = True
params.minInertiaRatio = 0.01

det = cv2.SimpleBlobDetector_create(params)

keypoints = det.detect(img)

im_with_key = cv2.drawKeypoints(img, keypoints, np.array([]),
            (0,0,255),cv2.DRAW_MATCHES_FLAGS_DRAW_RICH_KEYPOINTS)
#----------

titles = ['Input','Inverted','Grayscaled','Thresholded','blobpart']
images = [img, img_inv, gray, threshold, im_with_key]

for i in range(5):
    cv2.imshow(titles[i], images[i])
cv2.waitKey(0)
cv2.destroyAllWindows()

服务：

<?php

namespace Acme\UserBundle\EventListener;

use Doctrine\ORM\EntityManager;
use FOS\UserBundle\Event\UserEvent;
use FOS\UserBundle\FOSUserEvents;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;

class RegistrationListener implements EventSubscriberInterface
{
    /**
     * @var EntityManager
     */
    private $em;
/**
 * @param \Doctrine\ORM\EntityManager $entityManager
 */
public function __construct(EntityManager $entityManager)
{
    $this->em = $entityManager;
}

/**
 * {@inheritdoc}
 */
public static function getSubscribedEvents()
{
    return array(
        FOSUserEvents::REGISTRATION_INITIALIZE => 'onRegistrationInit',
    );
}

public function onRegistrationInit(UserEvent $userEvent)
{
    $user = $userEvent->getUser();

    $user->setPassword('abcdeffffff');

}

因此密码未设置，并显示密码不应为空白。

我做错了什么？任何帮助！

编辑：

问题是我在错误的地方定义服务。

而不是#src/Acme/UserBundle/Resources/config/services.yml services: acme_user.registration: class: Acme\UserBundle\EventListener\RegistrationListener arguments: entityManager: "@doctrine.orm.entity_manager" tags: - { name: kernel.event_subscriber}，它应该是src/Acme/UserBundle/Resources/config/services.yml。

我在http://symfony.com/doc/master/bundles/FOSUserBundle/controller_events.html中看到了app/config/services.yml，但却没有为我工作！

也许我错了，但我认为您的服务定义使用features from Symfony 3.3，但您使用的是Symfony 3.2.8，例如

3.3版中的新功能：在Symfony 3.3中添加了通过名称（$ adminEmail）配置参数的功能。以前，您只能通过其索引（在本例中为2）或使用其他参数的空引号来配置它。

尝试将服务定义更新为：

#src/Acme/UserBundle/Resources/config/services.yml
services:
    acme_user.registration:
        class: Acme\UserBundle\EventListener\RegistrationListener
        arguments: ["@doctrine.orm.entity_manager"]
        tags:
            - { name: kernel.event_subscriber}

还有一句话：当您实际使用订阅者时，您应该将班级RegistrationListener重命名为RegistrationSubscriber。

未触发FOSUserBundle事件REGISTRATION_INITIALIZE
