Jython and httplib2

I'm trying to follow this blog post about headless Oauth authentication:

http://blog.databigbang.com/automated-browserless-oauth-authentication-for-twitter/

Basically I;m trying to use jython to call Htmlunit, open the authorization webpage and accept it. However there's some incompatibility between jython and httplib2

File "/Users/andrey/jython2.7b1/Lib/site-packages/httplib2-0.8-py2.7.egg/httplib2/iri2uri.py", line 71, in iri2uri
    authority = authority.encode('idna')
LookupError: unknown encoding 'idna'

How to fix this error? If I import encodings.idna, then stringprep, re, codecs must be also imported, which jython doesn't have.

Jython doesn't have idna support, instead you have to call Java's if you want to do the same thing.

To encode Unicode to IDNA ASCII format:

import java.net.IDN
authority = java.net.IDN.toAscii(authority)

To decode IDNA ASCII into Unicode:

authority = java.net.IDN.toUnicode(authority)

If you're modifying httplib2 (or any other library) and don't want to break its functionality for other Python implementations, you can do something like this:

import platform
if platform.python_implementation() == "Jython":
    import java.net.IDN
    # do IDNA things here
else:
    # use .encode('idna') Pythonically
