如何使用boto在S3存储桶中重命名键?
在Amazon S3中,您无法重命名文件。您可以使用新名称将其复制,然后删除原始文件,但没有适当的重命名功能。
这里是一个使用Boto 2复制S3对象的Python函数示例:
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。你需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
//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);
