I need to transfer some data (nothing fancy, some dictionaries, strings,
numbers and lists, basically) between 2 Python processes. However, the data
(string values) is potentially not ASCII, but the transport is (I'm piping
between 2 processes, but thanks to nasty encoding issues, the only characters I
can be sure won't be mangled are ASCII).
What's the best ASCII-only protocol to use that's portable between versions of
Python back to about 2.6/2.7 and in the stdlib, so I don't need external
modules?
At the moment, I'm using
encoded = json.dumps([ord(c) for c in json.dumps(obj)])
decoded = json.loads(''.join([chr(n) for n in json.loads(encoded)]))
The double-encoding ensures that non-ASCII characters don't make it into the
result.
This works fine, but is there something simpler (i.e., less of a hack!) that I
could use? (Base64 and the like don't work because they encode bytes->strings,
not strings->strings).
Thanks,
Paul
