日志转存（Go SDK V2）_对象存储(OSS)-阿里云帮助中心

访问OSS的过程中会产生大量的访问日志。您可以通过日志转存功能将这些日志按照固定命名规则，以小时为单位生成日志文件写入您指定的存储空间（Bucket）。

注意事项

要开启Bucket的日志转存，您必须有oss:PutBucketLogging权限；要查看日志转存配置，您必须有oss:GetBucketLogging权限；要关闭日志转存，您必须有oss:DeleteBucketLogging权限。具体操作，请参见为RAM用户授予自定义的权限策略。

示例代码

开启日志转存

以下代码用于开启日志转存功能。

package main

import (
	"context"
	"flag"
	"github.com/aliyun/alibabacloud-oss-go-sdk-v2/oss/vectors"
	"log"

	"github.com/aliyun/alibabacloud-oss-go-sdk-v2/oss"
	"github.com/aliyun/alibabacloud-oss-go-sdk-v2/oss/credentials"
)

var (
	region     string
	bucketName string
	accountId  string
)

func init() {
	flag.StringVar(&region, "region", "", "The region in which the vector bucket is located.")
	flag.StringVar(&bucketName, "bucket", "", "The name of the vector bucket.")
	flag.StringVar(&accountId, "account-id", "", "The id of vector account.")
}

func main() {
	flag.Parse()
	if len(bucketName) == 0 {
		flag.PrintDefaults()
		log.Fatalf("invalid parameters, bucket name required")
	}

	if len(region) == 0 {
		flag.PrintDefaults()
		log.Fatalf("invalid parameters, region required")
	}

	if len(accountId) == 0 {
		flag.PrintDefaults()
		log.Fatalf("invalid parameters, accounId required")
	}

	cfg := oss.LoadDefaultConfig().
		WithCredentialsProvider(credentials.NewEnvironmentVariableCredentialsProvider()).
		WithRegion(region).WithAccountId(accountId)

	client := vectors.NewVectorsClient(cfg)

	request := &vectors.PutBucketLoggingRequest{
		Bucket: oss.Ptr(bucketName),
		BucketLoggingStatus: &vectors.BucketLoggingStatus{
			&vectors.LoggingEnabled{
				TargetBucket: oss.Ptr("TargetBucket"),
				TargetPrefix: oss.Ptr("TargetPrefix"),
				LoggingRole:  oss.Ptr("AliyunOSSLoggingDefaultRole"),
			},
		},
	}
	result, err := client.PutBucketLogging(context.TODO(), request)
	if err != nil {
		log.Fatalf("failed to put vector bucket logging %v", err)
	}

	log.Printf("put vector bucket logging result:%#v\n", result)
}

查看日志转存配置

以下代码用于查看日志转存配置。

package main

import (
	"context"
	"flag"
	"github.com/aliyun/alibabacloud-oss-go-sdk-v2/oss/vectors"
	"log"

	"github.com/aliyun/alibabacloud-oss-go-sdk-v2/oss"
	"github.com/aliyun/alibabacloud-oss-go-sdk-v2/oss/credentials"
)

var (
	region     string
	bucketName string
	accountId  string
)

func init() {
	flag.StringVar(&region, "region", "", "The region in which the vector bucket is located.")
	flag.StringVar(&bucketName, "bucket", "", "The name of the vector bucket.")
	flag.StringVar(&accountId, "account-id", "", "The id of vector account.")
}

func main() {
	flag.Parse()
	if len(bucketName) == 0 {
		flag.PrintDefaults()
		log.Fatalf("invalid parameters, bucket name required")
	}

	if len(region) == 0 {
		flag.PrintDefaults()
		log.Fatalf("invalid parameters, region required")
	}

	if len(accountId) == 0 {
		flag.PrintDefaults()
		log.Fatalf("invalid parameters, accounId required")
	}

	cfg := oss.LoadDefaultConfig().
		WithCredentialsProvider(credentials.NewEnvironmentVariableCredentialsProvider()).
		WithRegion(region).WithAccountId(accountId)

	client := vectors.NewVectorsClient(cfg)

	request := &vectors.GetBucketLoggingRequest{
		Bucket: oss.Ptr(bucketName),
	}
	getResult, err := client.GetBucketLogging(context.TODO(), request)
	if err != nil {
		log.Fatalf("failed to get vector bucket logging %v", err)
	}

	log.Printf("get vector bucket logging result:%#v\n", getResult)
}
