Paypal ipn returns nil

Rails
1

while testing IPN validations with the PayPal gem,

I keep getting a nil object message for notify.acknowledge

even though notify is not empty

notify = Paypal::Notification.new(request.raw_post)

notify
=> #<Paypal::Notification:0x398d9d0
@raw="receiver_id=D31B7IUDQITUL&business=paypal%40yourdo…etc etc

notify.acknowledge
NoMethodError: You have a nil object when you didn’t expect it!

Hello Dion,

Did you look at line 209 of notification ? 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’

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 = 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

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”

uri = URI.parse(@notify.ipn_url)
=> #<URI::HTTP:0x1c53c50 URL:
http://www.eliteweaver.co.uk/testing/ipntest.php>

http = Net::HTTP.new(uri.host, uri.port)
=> #<Net::HTTP www.eliteweaver.co.uk:80 open=false>

That only says that the connection is not open. 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 !
