GolangでMessagePackでシリアライズした構造体をAerospikeに保存する

Last updated at Posted at 2017-05-30

コード

package main

import (
	"fmt"

	as "github.com/aerospike/aerospike-client-go"
	"github.com/ugorji/go/codec"
)

type Human struct {
	Name struct {
		First string
		Last  string
	}
	Age int
}

// MessagePackでシリアライズしてAerospikeに保存
func put() {
	ieyasu := &Human{
		Name: struct {
			First string
			Last  string
		}{
			"Ieyasu",
			"Tokugawa",
		},
		Age: 70,
	}

	var buf []byte
	mh := &codec.MsgpackHandle{RawToString: true}
	codec.NewEncoderBytes(&buf, mh).Encode(ieyasu)

	client, _ := as.NewClient("localhost", 3000)
	key, _ := as.NewKey("bar", "set", "key")
	bins := as.BinMap{"selialized": buf}

	client.Put(nil, key, bins)
}

// Aerospikeから取得したデータをMessagePackでデシリアライズして表示
func get() {
	client, _ := as.NewClient("localhost", 3000)
	key, _ := as.NewKey("bar", "set", "key")
	res, _ := client.Get(nil, key)

	var human Human
	mh := codec.MsgpackHandle{RawToString: true}
	codec.NewDecoderBytes(res.Bins["selialized"].([]uint8), &mh).Decode(&human)

	fmt.Println(human)
}

func main() {
	put()
	get()
}

実行結果

{{Ieyasu Tokugawa} 70}
