proto与json的互相转换
- proto使用
- proto
- python dict和message
- python message序列化
- golang
- message序列化
- message转json
proto使用
生成逻辑请参考

proto
syntax = "proto3";message testRequest {string id = 1;
}
python dict和message
import jsonfrom google.protobuf.json_format import MessageToJson, MessageToDict
from google.protobuf.json_format import ParseDict, Parsefrom grpc0.code.test_pb2 import testRequestif __name__ == '__main__':proto_obj = testRequest(id="123",)print(f"{MessageToDict(proto_obj)=}")print(f"{MessageToJson(proto_obj)=}")json_obj = {"id": "456"}print(f"{Parse(json.dumps(json_obj), testRequest)=}")print(f"{ParseDict(json_obj, testRequest)=}")MessageToDict(proto_obj)={'id': '123'}
MessageToJson(proto_obj)='{\n "id": "123"\n}'
Parse(json.dumps(json_obj), testRequest)=<class 'test_pb2.testRequest'>
ParseDict(json_obj, testRequest)=<class 'test_pb2.testRequest'>
python message序列化
import jsonfrom google.protobuf.json_format import MessageToJson, MessageToDict
from google.protobuf.json_format import ParseDict, Parsefrom grpc0.code.test_pb2 import testRequestif __name__ == '__main__':proto_obj = testRequest(id="123",)proto_bytes = proto_obj.SerializeToString()print(proto_bytes)proto_obj1 = testRequest()proto_obj1.ParseFromString(proto_bytes)print(proto_obj)print(proto_obj1)
b'\n\x03123'
id: "123"
id: "123"
golang
在golang使用比较简单，protobuf生成的go struct是支持proto和json的序列化和反序列化的
message序列化
out, err := proto.Marshal(protoObj)
err := proto.Unmarshal(in, &protoObj)
message转json
out, err := json.Marshal(protoObj)
err := json.Unmarshal(in, &protoObj)
