Protocol buffer data to python dictionary , gRPC message to Dictionary

Question

I have data from gRPC. Which is type of protocol buffer, It looks like to dictionary, but it is not. For my case: The type of data: <class 'google._upb._message.RepeatedCompositeContainer'> data:

 [manufacturer_device_id: "B0000B0204c45bbefa948b"
  scale: Days
  bucket_epoch_seconds: 1698552000
  bucket_epoch_seconds: 1698638400
  channel_usages {
   channel: 1
   usages: 798.64540227509769
   usages: 1353.0604314283914
  }
]

Now, i want to convert the above data to python dictionary. How can i do this, can anyone help me? Advance thanks

You can use MessageToDict,

from google.protobuf.json_format import (
    MessageToDict,
)

request_data_dict: Dict = MessageToDict(
    message,
    preserving_proto_field_name=True,
    use_integers_for_enums=False,
    including_default_value_fields=True,
)

Where,

message – The protocol buffers message instance to serialize.

including_default_value_fields – If True, singular primitive fields, repeated fields, and map fields will always be serialized. If False, only serialize non-empty fields. Singular message fields and oneof fields are not affected by this option.

preserving_proto_field_name – If True, use the original proto field names as defined in the .proto file. If False, convert the field names to lowerCamelCase.

use_integers_for_enums – If true, print integers instead of enum names.
