騰訊/阿里雲物件儲存上傳+刪除
- 建立儲存桶 （後面會用到 儲存庫名稱、訪問域名、以及region） region（地域和訪問域名）的查詢參考： https://cloud.tencent.com/document/product/436/6224
- https://www.aliyun.com/product/oss
常用的阿里雲、騰訊雲
2.建立Api金鑰 （後面會用到 secretId、secretKey）
application.yml
qcloud:
path: 域名地址
bucketName: 儲存庫名稱
secretId: 金鑰生成的secretId
secretKey: 金鑰生成的secretKey
region: 地域簡稱
prefix: /images/
