在golang中获取s3对象到期时间

go get github.com/aws/aws-sdk-go

package main

import (
	"fmt"
	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/session"
	"github.com/aws/aws-sdk-go/service/s3"
)

func main() {
	// 创建AWS会话
	sess := session.Must(session.NewSessionWithOptions(session.Options{
		SharedConfigState: session.SharedConfigEnable,
	}))

	// 创建S3服务客户端
	svc := s3.New(sess)

	// 指定S3存储桶和对象的信息
	bucket := "your_bucket_name"
	key := "your_object_key"

	// 构建获取对象元数据的输入参数
	input := &s3.HeadObjectInput{
		Bucket: aws.String(bucket),
		Key:    aws.String(key),
	}

	// 调用S3服务的HeadObject方法获取对象元数据
	result, err := svc.HeadObject(input)
	if err != nil {
		fmt.Println("Error:", err)
		return
	}

	// 获取对象的到期时间
	expiration := result.Expiration
	fmt.Println("Object expiration:", expiration)
}
