Symfony 3,DI - 为参数添加服务

Question

我有这个代码

services:
  repo.game:
    class: Doctrine\ORM\EntityRepository
    factory_service: doctrine.orm.default_entity_manager
    factory_method: getRepository
    arguments:
        - AppBundle\Entity\Game

  file.upload.listener:
    class: AppBundle\Listener\FileUploadListener
    arguments: [@repo.game]
    tags:
        - { name: "kernel.event_listener", event: "oneup_uploader.post_upload", method: "onUpload" }

这在<= 2.8中运行良好,但在3.0中我收到此错误消息

[Symfony\Component\DependencyInjection\Exception\InvalidArgumentException] The file "/ext/thing/app/config/services.yml" does not contain valid YAML.

[Symfony\Component\Yaml\Exception\ParseException] The reserved indicator "@" cannot start a plain scalar; you need to quote the scalar at line 14 (near "arguments: [@repo.game]").

我的/ext/thing/app/config/services.yml文件中没有其他内容

Answer 1

参考yaml部分的UPGRADE指南:

使用@,`,|或>启动不带引号的字符串会导致ParseException.

因此,请尝试按以下方式修改配置:

 file.upload.listener:
    class: AppBundle\Listener\FileUploadListener
    arguments: ["@repo.game"]
    tags:
        - { name: "kernel.event_listener", event: "oneup_uploader.post_upload", method: "onUpload" }

希望这有帮助
