Question regarding JSON serializable messages

[Gerrit91]

Hey,

I wanted to ask if it is possible to somehow serialize response messages into JSON?

The string representation of the message is quite special and trying to encode a message with the json module fails with TypeError: Object of type Project is not JSON serializable.

Hi @Gerrit91 - protobuf messages don't work with the json module but provide methods like MessageToJson for serializing to JSON.

>>> from example.eliza_pb2 import SayRequest
>>> from google.protobuf.json_format import MessageToJson
>>> msg = SayRequest(sentence="Hello")
>>> MessageToJson(msg)
'{\n  "sentence": "Hello"\n}'

MessageToJson provides standard formatting parameters like indent but if you need to use json itself for some reason, there is also MessageToDict which can then be used with it.

That works like a charm. I somehow was unable to find it.

Thanks for the pointer and also for providing the connect integration in general. We use Ansible for our deployments and it allows us to natively integrate with our API. Awesome. :)
