protoc

• Download

go get -u github.com/golang/protobuf/{protoc-gen-go,proto}

syntax = "proto3";
package example;

message person {    //產生Person struct
    int32 id = 1;
    string name = 2;
}

message all_person {    //產生AllPerson struct
    repeated person Per = 1;
}

編譯 protoc --go_out=. person.proto
會產生 person.pb.go

package main

import (
    "github.com/golang/protobuf/proto"
    "Demo/example"
    "log"
)

func main() {
    // 为 AllPerson 填充数据
    p1 := example.Person{
        Id:*proto.Int32(1),
        Name:*proto.String("xieyanke"),
    }

    p2 := example.Person{
        Id:2,
        Name:"gopher",
    }

    all_p := example.AllPerson{
        Per:[]*example.Person{&p1, &p2},
    }

    // 对数据进行序列化
    data, err := proto.Marshal(&all_p)  
    if err != nil {
        log.Fatalln("Mashal data error:", err)
    }

    // 对已经序列化的数据进行反序列化
    var target example.AllPerson
    err = proto.Unmarshal(data, &target)
    if err != nil{
        log.Fatalln("UnMashal data error:", err)
    }

    println(target.Per[0].Name) // 打印第一个 person Name 的值进行反序列化验证
}
