Ho to use string concatenation in an http-block in Inspec?

Question

I've got an Inspec-control containing a http-block. The URL is saved in a variable called DNScloudui['value'] - I want to add https:// to the beginning of the URL.

DNScloudui = attribute('DNS_name_cloudui')

control 'Website reachability' do
  title 'Check reachability by GET requests'
  describe http(DNScloudui['value'], method: 'GET') do
    its('status') { should cmp 200 }
  end
end

How can I achieve that?

Answer 1

assuming that DNScloudui returns you a non-nil value, then you can use string interpolation to get the value of the DNScloudui variable. for instance:

DNScloudui = attribute('DNS_name_cloudui')

control 'Website reachability' do
  title 'Check reachability by GET requests'
  describe http("https://#{DNScloudui['value']}", method: 'GET') do
    its('status') { should cmp 200 }
  end
end

also, looking at the name of your DNScloudui variable, i would suggest to stick to ruby naming conventions and style guides
