阿里云OSS文件上传下载与文件删除及检索示例
实践环境
运行环境：
Python 3.5.4
CentOS Linux release 7.4.1708 (Core)/Win10
需要安装以下类库：
pip3 install setuptools_rust1.1.2
pip3 install Crypto1.4.1 # Win10下，安装后，需要更改 site-packages下crypto包名称为Crypto
pip3 install cryptography3.3.2 # 注意，如果不指定版本，安装oss2时会报错：error: can't find Rust compiler
pip3 install oss22.15.0
