what is special variables

In order to simplify some high frequency use of variable access, we have defined some special variables, just like global variables.

how to access

you can directory access these variables in your function of Validator or Controller without define any formal parameter.

function demoController.getGV()
        -- you can access these variables
	return {
            requestContext = requestContext, 
            ctx = ctx, 
            session = session, 
            request = request, 
            response = response
        };
end
