如何从 Symfony2 config.yml 读取配置设置? [英] How do I read configuration settings from Symfony2 config.yml?

问题描述

我已经在我的 config.yml 文件中添加了一个设置:

I have added a setting to my config.yml file as such:

app.config:
    contact_email: [e-mail]
    ...

对于我的一生，我不知道如何将其读入变量.我在我的一个控制器中尝试了这样的事情:

For the life of me, I can't figure out how to read it into a variable. I tried something like this in one of my controllers:

$recipient =
$this->container->getParameter('contact_email');

但我收到一条错误消息:

But I get an error saying:

参数contact_email"必须是定义.

The parameter "contact_email" must be defined.

我已经清除了我的缓存，我还查看了 Symfony2 重新加载站点文档的所有地方，但我不知道如何执行此操作.

I've cleared my cache, I also looked everywhere on the Symfony2 reloaded site documentation, but I can't find out how to do this.

现在可能太累了，无法弄清楚这一点.有人可以帮忙吗?

Probably just too tired to figure this out now. Can anyone help with this?

推荐答案

与其在 app.config 中定义 contact_email，不如在 parameters 中定义它代码>条目:

Rather than defining contact_email within app.config, define it in a parameters entry:

parameters:
    contact_email: [e-mail]

您应该会发现您在控制器中进行的调用现在可以正常工作了.

You should find the call you are making within your controller now works.
