copyPart method

Copies part of an object.

Has the same functionality as uploadPart method, but data isn't passed in the request body. It's copied from an existing object.

Request

PUT /{bucket}/{key}?partNumber=PartNumber&uploadId=UploadId HTTP/1.1

Parameter	Description
`bucket`	Name of the resulting bucket.
`key`	Key of the resulting object. ID that the object is saved with in Object Storage.

Parameter	Description
`partNubmer`	ID that you assigned to the uploaded part.
`uploadId`	ID of the multipart upload returned by Object Storage at the start.

Use the necessary common request headers in requests.

The Content-Length header is required. The headers listed in the table below are also required.

Header	Description
`x-amz-copy-source`	The name of the bucket and the key of the object whose data will be copied, separated by the `/` character. For example, `x-amz-copy-source: /source_bucket/sourceObject`.
`x-amz-copy-source-range`	Byte range to copy from the source object. For example, if you specify `x-amz-copy-source-range:bytes=10-36`, then Object Storage will copy the range from the 10th to the 36th bytes of the source object.

If you want to add copy conditions, use the headers listed in the table below.

Use the headers from the table below if you need to change the default behavior of the copy method.

Header	Description
`x-amz-copy-source-if-match`	Object copying criteria. If the `ETag` of an object is the same as in the header, the object is copied. If the criteria isn't met, Object Storage returns a 412 error. Can be used with the `x-amz-copy-source-if-unmodified-since` header.
`x-amz-copy-source-if-none-match`	Object copying criteria. If the `ETag` of the object isn't the same as in the header, the object is copied. If the criteria isn't met, Object Storage returns a 412 error. Can be used with the `x-amz-copy-source-if-modified-since` method.
`x-amz-copy-source-if-unmodified-since`	Object copying criteria. The object is copied if it didn't change since the specified time. If the criteria isn't met, Object Storage returns a 412 error. Can be used with the `x-amz-copy-source-if-match` header.
`x-amz-copy-source-if-modified-since`	Object copying criteria. The object is copied if it changed since the specified time. If the criteria isn't met, Object Storage returns a 412 error. Can be used with the `x-amz-copy-source-if-none-match` header.

Responses can only contain common response headers.
