阿里云oss初使用

一、购买

二、配置RAM权限

https://ram.console.aliyun.com/users

1、创建用户

2、创建完成后注意获取AccessKey ID、AccessKey Secret（只展示一次，后面会用到）

3、添加权限，这里全部权限都添加上（我也没有仔细看，选中前面几个，后面就默认全选了）

三、创建Bucket

https://oss.console.aliyun.com/bucket

四、安装对应的SDK

1、找到对应的SDK

https://help.aliyun.com/document_detail/32006.html

2、选择对应的语言（这里使用Python）

3、安装SDK

4、操作案例，按提示填写对应的信息，新建python文件

五、运行时的一个报错
