Args: 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. indent: The JSON object will be pretty-printed with this indent level. An indent level of 0 or negative will only insert newlines. sort_keys: If True, then the output will be sorted by field names. Returns: A string containing the JSON formatted protocol buffer message. )�_Printer� ToJsonString)�message� including_default_value_fields�preserving_proto_field_name�indent� sort_keys�printerr r r � MessageToJson\ s r c C s t ||�}|j| �S )a� Converts protobuf message to a dictionary. When the dictionary is encoded to JSON, it conforms to proto3 JSON spec.

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.
