Hello Dion, 2006/8/29, Dion H.

That should give you a clue. Check Paypal::Notification.ipn\_url is not nil before calling too. ## Hope that helps !

hi there I set ipn.url in my controller to the test script I am using notify.ipn\_url = ‘[http://www.eliteweaver.co.uk/cgi-bin/webscr](http://www.eliteweaver.co.uk/cgi-bin/webscr)’ how can I test line 204 http = Net::HTTP.new(uri.host, uri.port) from the console as I suspect it is http that is nil ## notification.rb def acknowledge payload = raw ``` uri = URI.parse(self.class.ipn_url) request_path = "#{uri.path}?cmd=_notify-validate" request = Net::HTTP::Post.new(request_path) request['Content-Length'] = "#{payload.size}" request['User-Agent'] = "paypal-ruby -- ``` [http://rubyforge.org/projects/paypal/](http://rubyforge.org/projects/paypal/)" ``` http = Net::HTTP.new(uri.host, uri.port) http.verify_mode = OpenSSL::SSL::VERIFY_NONE unless @ssl_strict http.use_ssl = true request = http.request(request, payload) raise StandardError.new("Faulty paypal result: #{request.body}") ``` unless [“VERIFIED”, “INVALID”].include?(request.body) ``` request.body == "VERIFIED" end ``` cheers dion On 8/29/06, Francois B.

while evaluating this from the console, http returns false, which is why I must be getting nil > > @notify.ipn\_url = ‘[http://www.eliteweaver.co.uk/testing/ipntest.php](http://www.eliteweaver.co.uk/testing/ipntest.php)’ > > =\> “[http://www.eliteweaver.co.uk/testing/ipntest.php](http://www.eliteweaver.co.uk/testing/ipntest.php)” > > uri = URI.parse(@notify.ipn\_url) > > =\> #\ > [http://www.eliteweaver.co.uk/testing/ipntest.php](http://www.eliteweaver.co.uk/testing/ipntest.php)\> > > http = Net::HTTP.new(uri.host, uri.port) > > =\> #\ On 8/29/06, Dion H.

Not that it’s false. You need to initiate the request. Continue testing in the console / irb to see where it leads you. Sorry I can’t be more specific. You’re on the right track though. Also, nothing prevents you from editing notification.rb and adding logging statements. I often do: RAILS\_DEFAULT\_LOGGER.debug “some logging statement” in the libraries. Since the library’s running under Rails, it automatically gets access to the same logger the rest of Rails is using. ## Bye !
