if empty body, iOS crashed

[joseph-montanez]

When a get request with the content type of JSON has an empty body the application would crash. This should not happen, the developer it is forced to remove the content type which doesn't make sense. While on Android it would work fine. This at least brings consistency in that regard.

Here is the code that would crash an iOS application

    session = Net.build('https://httpbin.org') do
      header(:content_type, :json)
    end

    reachability = Net.reachable?('httpbin.org') { |reachable|
      if reachable
        session.get('/ip') { |response|
          puts 'success'
        }
      else
        puts 'host is down!'
      end
    }

    reachability.stop
