 <thead> 
 <tr> 
 <th style="width:104px;">中文</th> 
 <th style="width:107px;">英文</th> 
 <th>说明</th> 
 </tr> 
 </thead> 
 <tbody> 
 <tr> 
 <td style="width:104px;">存储空间</td> 
 <td style="width:107px;">Bucket</td> 
 <td>存储空间是用户用于存储对象（Object）的容器，所有的对象都必须隶属于某个存储空间。推荐一个项目创建一个Bucket。</td> 
 </tr> 
 <tr> 
 <td style="width:104px;">对象</td> 
 <td style="width:107px;">Object</td> 
 <td>对象是OSS存储数据的基本单元，也被称为OSS的文件。和传统的文件系统不同，对象没有文件目录层级结构的关系。对象由元信息（Object Meta），用户数据（Data）和文件名（Key）组成，并且由存储空间内部唯一的Key来标识。对象元信息是一组键值对，表示了对象的一些属性，比如最后修改时间、大小等信息，同时用户也可以在元信息中存储一些自定义的信息。</td> 
 </tr> 
 <tr> 
 <td style="width:104px;"> Region &nbsp; </td> 
 <td style="width:107px;"> 地域 </td> 
 <td>Region表示OSS的数据中心所在物理位置。用户可以根据费用、请求来源等选择合适的地域创建Bucket。一般来说，距离用户更近的Region访问速度更快。详情请参见<a href="https://help.aliyun.com/document_detail/31837.htm#concept-zt4-cvy-5db" rel="nofollow">OSS已经开通的Region</a>。</td> 
 </tr> 
 <tr> 
 <td style="width:104px;"> Endpoint </td> 
 <td style="width:107px;"> 访问域名 </td> 
 <td> Endpoint表示OSS对外服务的访问域名。OSS以HTTP RESTful API的形式对外提供服务，当访问不同的Region的时候，需要不同的域名。通过内网和外网访问同一个Region所需要的Endpoint也是不同的。例如杭州Region的外网Endpoint是oss-cn-hangzhou.aliyuncs.com，内网Endpoint是oss-cn-hangzhou-internal.aliyuncs.com。具体的内容请参见<a href="https://help.aliyun.com/document_detail/31837.htm#concept-zt4-cvy-5db" rel="nofollow">各个Region对应的Endpoint</a>。 </td> 
 </tr> 
 <tr> 
 <td style="width:104px;"> AccessKey </td> 
 <td style="width:107px;"> 访问密钥 </td> 
 <td> AccessKey简称AK，指的是访问身份验证中用到的AccessKeyId和AccessKeySecret。OSS通过使用AccessKeyId和AccessKeySecret对称加密的方法来验证某个请求的发送者身份。AccessKeyId用于标识用户；AccessKeySecret是用户用于加密签名字符串和OSS用来验证签名字符串的密钥，必须保密。 </td>

# 2 配置阿里云子账户 #

这里配置阿里云子账户是用于后面使用代码上传文件需要的两个参数**accessKeyId**,**secretAccessKey**
