前言

阿里云对象存储服务(Object Storage Service,简称 OSS),是阿里云提供的海量、平安、低成本、高牢靠的云存储服务。其数据设计持久性不低于 99.9999999999%(12 个 9),服务设计可用性(或业务连续性)不低于 99.995%。

OSS 具备与平台无关的 RESTful API 接口,您能够在任何利用、任何工夫、任何地点存储和拜访任意类型的数据。

您能够应用阿里云提供的 API、SDK 接口或者 OSS 迁徙工具轻松地将海量数据移入或移出阿里云 OSS。数据存储到阿里云 OSS 当前,您能够抉择规范存储(Standard)作为挪动利用、大型网站、图片分享或热点音视频的次要存储形式,也能够抉择老本更低、存储期限更长的低频拜访存储(Infrequent Access)和归档存储(Archive)作为不常常拜访数据的存储形式。

登录阿里云,进入到控制台

点击确定,就建好了。

留神 postman 抉择 file

这样就实现了
