php - Symfony 3，DI - 将服务添加到参数

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 中我收到了此错误消息


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


[Symfony\Component\Yaml\Exception\ParseException]
保留指示符“@”不能启动普通标量；您需要在第 14 行引用标量(靠近“arguments: [@repo.game]”)。


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

Answer 1

引用 yaml section 中的升级指南:

Starting an unquoted string with @, `, |, or > leads to a ParseException.

因此尝试按如下方式修改您的配置:

 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
