问题描述
我的parameters.yml文件具有:

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
%
表示法无效,但可以通过以下方式实现:
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
