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
