S3协议简介

S3协议（Simple Storage Service）是亚马逊公司开发的一种对象存储服务API，用于提供对象存储的访问和管理，S3协议支持HTTP和HTTPS协议，遵循RESTful架构风格，易于实现和扩展，S3协议包括以下几种操作命令：

1、PUT Object：创建或更新对象

2、GET Object：获取对象

3、DELETE Object：删除对象

4、LIST Objects：列出对象

5、Head Object：获取对象的元数据

6、Copy Object：复制对象

7、Restore Object：还原归档对象

8、Select Object：查询对象内容

9、Versioning：版本控制
