ES（Elasticsearch）--elastic包

ES（Elasticsearch）–elastic包

	Go語言操作ES，使用第三方庫，不用官方庫 [https://github.com/olivere/elastic]

​ github.com/olivere/elastic/v7： 版本必須與ES版本一致

package main

import (
	"context"
	"fmt"

	"github.com/olivere/elastic/v7"
)

// Elasticsearch demo

type Person struct {
	Name    string `json:"name"`
	Age     int    `json:"age"`
	Married bool   `json:"married"`
}

func main() {
	client, err := elastic.NewClient(elastic.SetURL("http://192.168.42.133:9200"))
	if err != nil {
		// Handle error
		panic(err)
	}

	fmt.Println("connect to es success")
	//創建一條數據
	p1 := Person{Name: "rion", Age: 22, Married: false}
	put1, err := client.Index().
		Index("user"). //Index 數據庫
		BodyJson(p1).
		Do(context.Background())
	if err != nil {
		// Handle error
		panic(err)
	}
	fmt.Printf("Indexed user %s to index %s, type %s\n", put1.Id, put1.Index, put1.Type)
}
