amazon-s3 - Amazon S3 boto：如何重命名存储桶中的文件？

Question

如何使用 boto 重命名存储桶中的 S3 密钥？

Answer 1

您无法重命名 Amazon S3 中的文件。您可以使用新名称复制它们，然后删除原始名称，但没有适当的重命名功能。

Answer 2

下面是一个 Python 函数示例，它将使用 Boto 2 复制 S3 对象：

import boto

def copy_object(src_bucket_name,
                src_key_name,
                dst_bucket_name,
                dst_key_name,
                metadata=None,
                preserve_acl=True):
    """
    Copy an existing object to another location.

    src_bucket_name   Bucket containing the existing object.
    src_key_name      Name of the existing object.
    dst_bucket_name   Bucket to which the object is being copied.
    dst_key_name      The name of the new object.
    metadata          A dict containing new metadata that you want
                      to associate with this object.  If this is None
                      the metadata of the original object will be
                      copied to the new object.
    preserve_acl      If True, the ACL from the original object
                      will be copied to the new object.  If False
                      the new object will have the default ACL.
    """
    s3 = boto.connect_s3()
    bucket = s3.lookup(src_bucket_name)

    # Lookup the existing object in S3
    key = bucket.lookup(src_key_name)

    # Copy the key back on to itself, with new metadata
    return key.copy(dst_bucket_name, dst_key_name,
                    metadata=metadata, preserve_acl=preserve_acl)

Answer 3

没有直接的方法来重命名 s3 中的文件。你要做的是用新名称复制现有文件（只需设置目标键）并删除旧文件。谢谢

Answer 4

//Copy the object
AmazonS3Client s3 = new AmazonS3Client("AWSAccesKey", "AWSSecretKey");

CopyObjectRequest copyRequest = new CopyObjectRequest()
      .WithSourceBucket("SourceBucket")
      .WithSourceKey("SourceKey")
      .WithDestinationBucket("DestinationBucket")
      .WithDestinationKey("DestinationKey")
      .WithCannedACL(S3CannedACL.PublicRead);
s3.CopyObject(copyRequest);

//Delete the original
DeleteObjectRequest deleteRequest = new DeleteObjectRequest()
       .WithBucketName("SourceBucket")
       .WithKey("SourceKey");
s3.DeleteObject(deleteRequest);
