腾讯/阿里云对象存储上传+删除

1. 创建储存桶 （后面会用到 储存库名称、访问域名、以及region） region（地域和访问域名）的查询参考： https://cloud.tencent.com/document/product/436/6224
2. https://www.aliyun.com/product/oss

常用的阿里云、腾讯云

2.创建Api密钥 （后面会用到 secretId、secretKey）

application.yml

<code>qcloud:

path: 域名地址

bucketName: 储存库名称

secretId: 密钥生成的secretId

secretKey: 密钥生成的secretKey

region: 地域简称

prefix: /images/

工具类：

import com.qcloud.cos.auth.BasicCOSCredentials;

import com.qcloud.cos.exception.CosClientException;
