Symfony2:如何读取 config.yml 中的参数数组

2022-01-14 00:00:00 yaml php symfony

我的 parameters.yml 文件有:

my parameters.yml file has:

parameters:
     title:
          subtitle: value

我想将 value 传递给 config.yml 中的服务

i want to pass the value to a service in config.yml

my_service:
        class: the_class
        arguments: [ %title.subtitle%] //didn't work
        arguments: [ %title['subtitle']%] //didn't work

我该怎么做?

推荐答案

% 表示法不起作用，但可以通过以下方式完成:

The % notation doesn't work but it can be accomplished the following way:

my_service:
    class: the_class
    arguments: ["@=container.getParameter('title')['subtitle']"]

它至少适用于 symfony 2.7.3

It works at least for symfony 2.7.3
