RE: [Zope] how to decode base64 in DTML?

4 May 2006

      ...
From: Andreas Jung [mailto:lists@zopyx.com]
...
import cStringIO
import mimetools
import binascii
binascii.a2b_base64('YWxla2liYW5nb0B6dWcuY3o=\n')
in commandline python works OK.
Move such code inside a PythonScript..such code does not belong into
DTML..
it just bad style.
I was try this PythonScript (parameter: xemail):

import cStringIO
import mimetools
from Products.PythonScripts.Utility import allow_module
allow_module("base64")

xe=xemail + '=\n'
print xe.decode('base64')
return printed

... but it give me import error (bottom of that page).

So I try to write External method. Many rewrites, many tries, here are
working one - note that allow_module does not work:

import binascii
def preved64(xemail):
    xe=xemail + '=\n'
    return binascii.a2b_base64(xe)

Using: <dtml-var "externalmethodname('kjsdjhf_base64_lkskd')">

Great thanks to all!!!
