使用Python，如何获得Google protobuf消息的二进制序列化？

pip install protobuf

syntax = "proto3";

message Person {
    string name = 1;
    int32 age = 2;
}

protoc --python_out=. example.proto

import example_pb2

# 创建一个Person消息
person = example_pb2.Person()
person.name = "张三"
person.age = 25

# 序列化Person消息
serialized_person = person.SerializeToString()

print(serialized_person)

# 反序列化Person消息
person_copy = example_pb2.Person()
person_copy.ParseFromString(serialized_person)

print(person_copy.name)
print(person_copy.age)
