How can I send JSON-formatted cookie data using Python on Google App Engine?

Question

I\'m trying to encode an object in a Python script and set it as a cookie so I can read it with client-side JavaScript.

I\'ve run into problems every way I\'ve tried

Answer 1

On the Python side:

1. json.dumps the string
2. escape spaces - just call .replace(' ', '%20')
3. Call urllib.parse.quote_plus() then write the string to the cookie

On the JavaScript side:

1. read the cookie
2. pass it through decodeURIComponent()
3. JSON.parse it

This seems to be the cleanest way I've found.
