Question

我在我的symfony 3.2。（8？）项目中有2个工作服务，并且必须达到3.3（目前为3.3.2）。我的一项服务工作得很好，第二项是给我错误：
services.yml

parameters:
    #parameter_name: value

services:
    _defaults:
        autowire: true
        autoconfigure: true
        public: false
    AppBundle\:
        resource: '../../src/AppBundle/*'
        exclude: '../../src/AppBundle/{Entity,Repository}'
    list_brands:
          class: AppBundle\Service\ListBrands
          arguments: [ '@doctrine.orm.entity_manager' ]
          calls:
           - method: getBrands
    picture_upload:
          class: AppBundle\Service\UploadPicture
          arguments: ['@kernel']

SRC \的appbundle \服务\ UploadPicture.php

<?php

namespace AppBundle\Service;

use DateTime;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Symfony\Component\HttpKernel\Kernel;

class UploadPicture
{
    protected $kernel;

    public function __construct(Kernel $kernel)
    {
        $this->kernel = $kernel;
    }

    public function uploadPicture($object, string $oldPic, string $path)
    {
        /** @var UploadedFile $image */
        $image = $object->getImage();

        $time = new DateTime('now');

        if ($image) {
            $imgPath = '/../web/' . $path;

            $filename = $time->format('d-m-Y-s') . md5($time->format('s')) . uniqid();

            $image->move($this->kernel->getRootDir() . $imgPath,$filename . '.png');

            $object->setImage($path . $filename . '.png');
        } else {
            $object->setImage($oldPic);
        }
    }
}

错误： 您已请求不存在的服务＆＃34; picture_upload＆＃34;。
这样称呼： $uploadService = $this->get('picture_upload');

您还没有写过如何注入/调用您的服务，但是调用$this->get()听起来像是来自控制器内的呼叫。我想这与Symfony的新变化和public属性的默认服务配置有关。

请检查配置中的以下注释行：

# services.yml
services:
    _defaults:
        autowire: true
        autoconfigure: true
        public: false # here you are setting all service per default to be private
    AppBundle\:
        resource: '../../src/AppBundle/*'
        exclude: '../../src/AppBundle/{Entity,Repository}'
    list_brands:
          class: AppBundle\Service\ListBrands
          arguments: [ '@doctrine.orm.entity_manager' ]
          calls:
           - method: getBrands
    picture_upload:
          class: AppBundle\Service\UploadPicture
          arguments: ['@kernel']  
          public: true # you need to explicitly set the service to public

您需要将服务标记为公共，默认情况下（不推荐）或在服务定义中明确标记。

自symfony 3.3以来不存在的服务错误
