在自定义类（Symfony2）中使用参数值

Question

I have some parameter values in app/config/parameters.yml

parameters:
    database_host: 127.0.0.1
    database_port: null
    database_name: database_name
    ...
    igv: 0.18
    isc: 0.18

Now, I want to use the parameters in a Custom class in AppBundle/CustomClass.php. How can I use this parameters? I try $this->container->get('igv') but not works.

Answer 1

In services.yml:

my_app.customclass:
    class:  AppBundle\CustomClass
    arguments: ['%igv%', '%isc%']

Add the arguments to the constructor of AppBundle\\CustomClass.
