简单概念

• Bucket：OSS 存储区域名

• Bucket 域名：bucket 域名

• EndPoint：大区域名

• AccessKey ID：阿里云产品的通用id

• Access Key Secret：密钥

配置文件

oss:
  endpoint: 大区域名   # oss-cn-xxxxxx.aliyuncs.com
  keyid:    阿里云产品的通用id
  keysecret: 密钥     # 填写生成的Accesssecret
  bucketname: bucket名称
  filehost: folder    # bucket下的文件夹路径
