How to communicate binary data in nameko rpc?

Question

It seems json is the default way for serialization data in nameko rpc. If I call rpc.my_service.send(b'\x01\'), it will raise exception kombu.exceptions.EncodeError: Object of type 'bytes' is not JSON serializable

Is there a way to send binary data in nameko rpc? eg, pickle. Would please give me a short example? Thank you in advance.

You can serialize with pickle by specifying it in your config file. Simply:

# config.yaml
serializer: pickle

And

nameko run my_service --config config.yaml

If you need something more advanced you can build your own serializer and again configure the service to use it with your config file:

# config.yaml
serializer: my_serializer
SERIALIZERS:
    my_serializer:
        encoder: 'path.to.encode.function'
        decoder: 'path.to.decode.function'
        content_type: 'application/x-my-serializer'

The encode and decode functions simply take a value and return a transformed version.

this is not working. what was the version you were using? – Ganatra Dec 23 '21 at 11:14 — Ganatra, Dec 23 '21 at 11:14
