Question

I\'m writing a script to automate data generation for a demo and I need to serialize in a JSON some data. Part of this data is an image, so I encoded it in base64, but when

Answer 1

Alternative solution would be encoding stuff on the fly with a custom encoder:

import json
from base64 import b64encode

class Base64Encoder(json.JSONEncoder):
    # pylint: disable=method-hidden
    def default(self, o):
        if isinstance(o, bytes):
            return b64encode(o).decode()
        return json.JSONEncoder.default(self, o)

Having that defined you can do:

m = {'key': b'\x9c\x13\xff\x00'}
json.dumps(m, cls=Base64Encoder)

It will produce:

'{"key": "nBP/AA=="}'
