4.6 利用protobuf生成的类来编码

package main

import (
    "fmt"
    "github.com/golang/protobuf/proto"
    "protocolbuffer_excise/pb"
)

func main() {
    person := &pb.Person{
        Name:   "Aceld",
        Age:    16,
        Emails: []string{"https://legacy.gitbook.com/@aceld", "https://github.com/aceld"},
        Phones: []*pb.PhoneNumber{
            &pb.PhoneNumber{
                Number: "13113111311",
                Type:   pb.PhoneType_MOBILE,
            },
            &pb.PhoneNumber{
                Number: "14141444144",
                Type:   pb.PhoneType_HOME,
            },
            &pb.PhoneNumber{
                Number: "19191919191",
                Type:   pb.PhoneType_WORK,
            },
        },
    }

    data, err := proto.Marshal(person)
    if err != nil {
        fmt.Println("marshal err:", err)
    }

    newdata := &pb.Person{}
    err = proto.Unmarshal(data, newdata)
    if err != nil {
        fmt.Println("unmarshal err:", err)
    }

    fmt.Println(newdata)

}
