CopyObject

请求语法

PUT /objectName HTTP/1.1
Host: bucketname.cos.chinac.com
Date: GMT Date
Authorization: SignatureValue
x-cos-copy-source: /bucket/object

请求Header

Name	Type	Description
x-cos-copy-source	string	复制源地址

细节分析

1. 拷贝操作需要请求者对源Object有读权限；
2. 源Object和目标Object必须属于同一个数据中心；
3. 拷贝操作涉及到的请求头，都是以“x-cos-”开头的，所以要加入签名字符串中；
4. 拷贝操作不限制源对象的对象大小
5. 拷贝操作会复制所有对象的用户自定义元数据（已"x-cos-meta-"开头的）
