[Zope] Anyone got some code that takes a dictionary and encodes it intoa cookie?

[Chris McDonough]

The marshal module may help here... it'll get you as far as serializing the
dict to a string at least.

>>> d = {'1':'foo', '2':'bar'}
>>> import marshal
>>> marshal.dumps(d)
'{s\x01\x00\x00\x002s\x03\x00\x00\x00bars\x01\x00\x00\x001s\x03\x00\x00\x00f
oo0'
>>> marshal.loads(marshal.dumps(d))
{'2': 'bar', '1': 'foo'}

This is marginally more secure than using pickle because marshal is more
restricted as to what it can serialize.  From the python docs:

The following types are supported: None, integers, long integers, floating
point numbers, strings, Unicode objects, tuples, lists, dictionaries, and
code objects, where it should be understood that tuples, lists and
dictionaries are only supported as long as the values contained therein are
themselves supported; and recursive lists and dictionaries should not be
written (they will cause infinite loops).
