我在Amazon S3中存储了几个对象,其内容类型我需要更改text/html为application/rss+xml.我认为应该可以使用复制命令执行此操作,为源和目标指定相同的路径.我正在尝试使用AWS cli工具执行此操作,但我收到此错误:

$ aws s3 cp s3://mybucket/feed/ogg/index.html \
            s3://mybucket/feed/ogg/index.html \
            --content-type 'application/rss+xml'
copy failed: s3://mybucket/feed/ogg/index.html
to s3://mybucket/feed/ogg/index.html
A client error (InvalidRequest) occurred when calling the
CopyObject operation: This copy request is illegal because it is
trying to copy an object to itself without changing the object's
metadata, storage class, website redirect location or encryption
attributes.

如果我为源和目标指定不同的路径,我不会收到错误:

$ aws s3 cp s3://mybucket/feed/ogg/index.html \
            s3://mybucket/feed/ogg/index2.html \
            --content-type 'application/rss+xml'
copy: s3://mybucket/feed/ogg/index.html
to s3://mybucket/feed/ogg/index2.html

即使命令成功完成,index2.html也会使用text/html内容类型创建对象,而不是 …
