如何使用适用于 Go v2 的 AWS SDK 删除非空 S3 存储桶
How to delete a non-empty S3 bucket using AWS SDK for Go v2
我正在使用 AWS SDK v2
我需要删除包含对象的存储桶
最好的方法是什么?有什么可以强制删除的吗?或者删除存储桶中的所有对象?
AWS 文档Deleting a bucket 描述了如何删除包含对象的存储桶。该文档还提供了执行以下步骤的 SDK 示例(用 Java 编写,但主要用作指南):
- 删除所有对象
- 删除所有对象版本(对于版本化存储桶)
- 最后删除存储桶
没有针对非空存储桶的“强制删除”选项。您需要执行上述步骤。
以下示例代码展示了如何完全删除非空桶:
func main() {
cfg, err := config.LoadDefaultConfig(context.TODO(), config.WithRegion("us-east-1"))
if err != nil {
log.Fatalf("Failed to load config: %v", err)
}
bucket := aws.String("your-bucket-name")
client := s3.NewFromConfig(cfg)
deleteObject := func(bucket, key, versionId *string) {
log.Printf("Object: %s/%s\n", *key, aws.ToString(versionId))
_, err := client.DeleteObject(context.TODO(), &s3.DeleteObjectInput{
Bucket: bucket,
Key: key,
VersionId: versionId,
})
if err != nil {
log.Fatalf("Failed to delete object: %v", err)
}
}
in := &s3.ListObjectsV2Input{Bucket: bucket}
for {
out, err := client.ListObjectsV2(context.TODO(), in)
if err != nil {
log.Fatalf("Failed to list objects: %v", err)
}
for _, item := range out.Contents {
deleteObject(bucket, item.Key, nil)
}
if out.IsTruncated {
in.ContinuationToken = out.ContinuationToken
} else {
break
}
}
inVer := &s3.ListObjectVersionsInput{Bucket: bucket}
for {
out, err := client.ListObjectVersions(context.TODO(), inVer)
if err != nil {
log.Fatalf("Failed to list version objects: %v", err)
}
for _, item := range out.DeleteMarkers {
deleteObject(bucket, item.Key, item.VersionId)
}
for _, item := range out.Versions {
deleteObject(bucket, item.Key, item.VersionId)
}
if out.IsTruncated {
inVer.VersionIdMarker = out.NextVersionIdMarker
inVer.KeyMarker = out.NextKeyMarker
} else {
break
}
}
_, err = client.DeleteBucket(context.TODO(), &s3.DeleteBucketInput{Bucket: bucket})
if err != nil {
log.Fatalf("Failed to delete bucket: %v", err)
}
}
您可能应该进一步优化它并使用 DeleteObjects
进行批量调用以减少请求开销。
