# 阿里云更新域名解析文档

# 阿里云信息，从阿里云获取填写即可
AliyunData:
  # 阿里云的AccessKey_ID , Access_Key_Secret , region_id
  # 获取方法，参考文档: https://help.aliyun.com/knowledge_detail/38738.html
  AccessKey_ID: 'AccessKey'
  Access_Key_Secret: 'Secret'

# DNS解析信息
UserData:
  # 需要修改的域名
  DomainName: '需要修改的域名'
  # 解析的主机
  RR: '需要修改的主机'
  # 解析的记录
  DomainType: '需要修改的记录类型'
  # 解析更新的值，如果填写 Auto_Lines ,则从命令行获取
  UpdateDomain: 'Auto_Lines'

根据配置文档来解析

需要将配置文件中的UpdateDomain 修改为需要修改解析的值，执行main.py即可

>python main.py
更新域名解析成功
域名:****** 主机:****** 记录类型:A 记录值:192.168.1.100

>

根据用户命令行指定来解析

需要将配置文件中的UpdateDomain 修改为Auto_Lines，执行main.py 需要解析的地址 即可

>python main.py 192.168.1.101
更新域名解析成功
域名:****** 主机:****** 记录类型:A  记录值:192.168.1.101
