Active Resource Spy

Posted by: David Bock on 02/09/2012

I'm doing a lot of work lately using ActiveResource.  I wanted to get 'down to the wire' and see the traffic flowing over http... so a quick google search, and I found an entry I had written in 2008.  I love it when that happens!  So I'm reblogging it with a slight change to make it work in Ruby 1.9.

If you're using rails, create an initializer name active_resource_spy.rb and drop in this content:

class ActiveResource::Connection
  # Creates new Net::HTTP instance for communication with
  # remote service and resources.
  def http
    http = Net::HTTP.new(@site.host, @site.port)
    http.use_ssl = @site.is_a?(URI::HTTPS)
    http.verify_mode = OpenSSL::SSL::VERIFY_NONE if http.use_ssl?
    http.read_timeout = @timeout if @timeout


    #Here's the addition that allows you to see the output
    http.set_debug_output $stderr
    return http
  end
end

All the data that flows over the http connection will be dumped to $stderr (the terminal you started the app in, unless you redirected it).
