Вы можете использовать метод google.protobuf.json_format.MessageToJson
для сериализации простого объекта protobuf в JSON. Например:
from google.cloud import language
from google.protobuf.json_format import MessageToJson
client = language.LanguageServiceClient()
document = language.types.Document(
content='Mona said that jogging is very fun.',
type='PLAIN_TEXT',
)
response = client.analyze_entity_sentiment(
document=document,
encoding_type='UTF32',
)
print(MessageToJson(response))
