类名称：Blob
方法名：copyTo

Blob.copyTo介绍

[英]Sends a copy request for the current blob to the target blob. Possibly also some of the metadata are copied (e.g. content-type).

Example of copying the blob to a different bucket with a different name.

String bucketName = "my_unique_bucket";

[中]向目标blob发送当前blob的复制请求。可能还会复制一些元数据（例如，内容类型）。
将blob复制到具有不同名称的不同bucket的示例。

String bucketName = "my_unique_bucket";
