Delete Objects in S3 Bucket

Question

• Why doesn’t it return error if we try to delete object that doesn’t exists?

  Answer: Because that’s what the specs says it should do -> “Removes the null version (if there is one) of an object and inserts a delete marker, which becomes the latest version of the object. If there isn’t a null version, Amazon S3 does not remove any objects.”, if the object doesn’t exists, it’s still not an error when calling deleteObject

• Error: cannot use objectkeys[i] (type string) as type *string in field value

  Answer: The AWS SDK uses string pointers for most of its inputs due to the vagueries of the AWS API. It does include a helper function, aws.String, for this purpose: aws.String(“STRING”),

• Error: invalid indirect of s3.ObjectIdentifier literal (type s3.ObjectIdentifier)

  Answer: You’ll need to create a pointer to the value you’re creating, which is done with & , * does the opposite, it dereferences a pointer.

  var objects []*s3.ObjectIdentifier
  for i := 0; i < len(objectkeys); i++ {
      objects[i] = &s3.ObjectIdentifier{
          Key: aws.String(objectkeys[i]),
      }
  }
