Is a fork of protobuf-to-dict (created by Ben Hodgson), stewarded by Eugene Van den Bulke as Ben does not appear to dedicate much time to it anymore.

protodict is a small Python library for 2 ways conversion between dicts and protocol buffers.

Use pip install protodict or python setup.py install.

Given the google.protobuf.message.Message subclass MyMessage:

>>> import protodict
>>> my_message = MyMessage()
>>> # pb_my_message is a protobuf string
>>> my_message.ParseFromString(pb_my_message)
>>> protodict.to_dict(my_message)
{'message': 'Hello'}

This library grew out of the desire to serialize a protobuf-encoded message to JSON. As JSON has no built-in binary type (all strings in JSON are Unicode strings), a field whose type is FieldDescriptor.TYPE_BYTES should be converted to a base64-encoded string.

If you want to encode bytes is this way, both to_dict() and to_protobuf() take an optional base64_bytes argument:

>>> # my_message is a google.protobuf.message.Message instance
>>> my_dict = to_dict(my_message, base64_bytes = True)
>>> to_protobuf(my_dict, base64_bytes = True)

By default, the integer representation is used for enum values. To use their string labels instead, pass use_enum_labels=True into to_dict:

>>> to_dict(my_message, use_enum_labels=True)

Tests are under src/tests/.

$ python setup.py nosetests

To regenerate src/tests/sample_pb2.py:

$ protoc --python_out=src -Isrc src/tests/sample.proto

protodict is written and maintained by Ben Hodgson, with significant contributions from Nino Walker, Jonathan Klaassen, and Tristram Gräbener. Eugene Van den Bulke's small contribution started with a corner case bug fix and an ignored PR which led to this fork.
