删除对象标签（GO）

以下代码用于删除对象标签：

package ks3test

import (
	"bufio"
	"bytes"
	"github.com/ks3sdklib/aws-sdk-go/aws/awserr"
	"github.com/ks3sdklib/aws-sdk-go/aws/awsutil"

)

var bucket = string("yourbucket")
var key = string("yourkey")
var key_encode = string("yourkey")
var key_copy = string("yourkey")
var content = string("content")
var prefix = "test/" //目录名称

// 金山云主账号 AccessKey 拥有所有API的访问权限，风险很高。
// 强烈建议您创建并使用子账号账号进行 API 访问或日常运维，请登录 https://uc.console.ksyun.com/pro/iam/#/user/list 创建子账号。
// 通过指定 host(Endpoint)，您可以在指定的地域创建新的存储空间。
var cre = credentials.NewStaticCredentials("ak", "sk", "") //online
var svc = s3.New(&aws.Config{
	//Region 可参考 [https://docs.ksyun.com/documents/6761](https://docs.ksyun.com/documents/6761)

	DisableSSL:       true, //是否禁用https
	LogLevel:         1,    //是否开启日志,0为关闭日志，1为开启日志
	LogHTTPBody:      true, //是否把HTTP请求body打入日志
	S3ForcePathStyle: true,
	Logger:           nil, //打日志的位置
})

//delObjectTagging
func DelTag(svc *s3.S3) {

	params := &s3.DeleteObjectTaggingInput{
		Bucket: aws.String(bucket), // Required
		Key:    aws.String(key),
	}
	resp, err := svc.DeleteObjectTagging(params)

	if err != nil {
		if awsErr, ok := err.(awserr.Error); ok {
			fmt.Println(awsErr.Code(), awsErr.Message(), awsErr.OrigErr())
			if reqErr, ok := err.(awserr.RequestFailure); ok {
				fmt.Println(reqErr.Code(), reqErr.Message(), reqErr.StatusCode(), reqErr.RequestID())
			}
		} else {
			fmt.Println(err.Error())
		}
	}

	fmt.Println("结果：\n", awsutil.StringValue(resp))
}
