[Zope] sending a post request to a secure site (paypal) from a python script/external method

[Edward Muller]

I do credit card authorization from zope via m2crypto

It's as simple as  ....

from M2Crypto import m2urllib
encodedParams = urllib.urlencode(params)
url = m2urllib.FancyURLopener()
u = url.open('https://place.you.are.posting.to',encodedParams)
data = u.read()

This is in an external method.

Hope this helps with your paypal question...
