Amazon S3 boto：如何重命名存储桶中的文件？

如何使用Boto在存储桶中重命名S3密钥？

您无法在Amazon S3中重命名文件。您可以使用新名称复制它们，然后删除原始名称，但是没有适当的重命名功能。

这是一个Python函数的示例，该示例将使用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)

在s3中没有直接重命名文件的方法。您需要做的是使用新名称复制现有文件（只需设置目标密钥）并删除旧文件。谢谢

//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);
