python - Pylons & Beaker: JSON Encoded Sessions -

-

need read pylons session data (just read, not write to) in node.js

once decode base64, i'm left string containing serialized python object which, pain parse in node.js

how can beaker serialize json instead? far easier node.js handle.

i had inside beaker find call "python serialized strings" python pickles.

i don't think more few lines change use json store dict.

here patch against https://bitbucket.org/bbangert/beaker/src/257f147861c8:
