Exception "can't convert URI::HTTPS into String"

Hello. I’m trying to to an http post to an https: url (paypal’s ipn
postback), and I’m getting this error: “can’t convert URI::HTTPS into
String”. Does anyone know what this means and how I can fix it? The
relevant code looks like this:

      PAYPAL_IPN_POSTBACK_URL = "https://www.sandbox.paypal.com"

      PAYPAL_IPN_POSTBACK_REQUEST_URI = "/cgi-bin/webscr"

http = Net::HTTP.new URI.parse(PAYPAL_IPN_POSTBACK_URL)

      ### from traces I know it gets here okay

      ### next line blows up with "can't convert URI::HTTPS into

String" ###

      http.request_post(PAYPAL_IPN_POSTBACK_REQUEST_URI,

request.raw_post) do |response|
### from traces I know it never gets here
response.read_body do |body|
STDOUT.puts body
end
end

This blows up on the second line, the call to request_post. Does
anyone know what the problem is? Incidentally, I know that there’s a
paypal gem I can use for the paypal postback, but I’ve come this far
and I’d like to get this working. Also, this is running in Ruby on
Rails.

Thanks for any help.

All you have to do is put .to_s at the end of your URI::HTTP to turn it
into a url string.
