Symfony 3, DI - 将服务添加到参数 [英] Symfony 3, DI - Add service to argument

问题描述

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

This worked fine in <= 2.8, but here in 3.0 I got this error message

<代码>[Symfony\Component\DependencyInjection\Exception\InvalidArgumentException]文件/ext/thing/app/config/services.yml"不包含有效YAML.

<代码>[Symfony\Component\Yaml\Exception\ParseException]保留指示符@"不能开始一个普通的标量；您需要引用第 14 行的标量(靠近参数:[@repo.game]").

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

There is nothing else in my /ext/thing/app/config/services.yml file

推荐答案

参考yaml 部分:

以@、`、| 或 > 开头的未加引号的字符串会导致解析异常.

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

所以尝试修改你的配置如下:

So try to modify your configuration as follow:

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