腾讯/阿里云对象存储上传+删除
- 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
- 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
qcloud:path: 域名地址bucketName: 储存库名称secretId: 密钥生成的secretIdsecretKey: 密钥生成的secretKeyregion: 地域简称prefix: /images/
