I have an URL defined as a parameter in parameters.yml. I want to create a service which is a SOAP client. The argument of the SOAP client is an URL for a wsdl file. In my case, the URL of the wsdl file is "%parameter_url%" + "?wsdl"`.
Is there a way to concatenate the "?wsdl" to a parameter already defined in YAML?
You don't need a concatenation character, you can append the constant directly after the parameter. For example, for a service definition in services.yml:
my.service: class: "%my.service.class%" arguments: - "@logger", - "%some_parameter%", - "%parameter_url%?wsdl", 
"%parameter_url%?wsdl"If you are looking to concatenate two parameters. You can do it this way:
parameters.yml
parameter_url: XXXXX parameter_type: ?wsdl
services.yml
my.service: class: %my.service.class% arguments: - @logger, - %some_parameter%, - '%parameter_url%%parameter_type%', Following up on redbirdo his response, since not quoting a scalar starting with the '%' indicator character is deprecated since Symfony 3.1:
my.service: class: "%my.service.class%" arguments: - "@logger" - "%some_parameter%" - "%parameter_url%?wsdl" # OR my.service: class: "%my.service.class%" arguments: ["@logger", "%some_parameter%", "%parameter_url%?wsdl"]
