# 在运行此脚本之前，请先在华为云DNS管理控制台内添加对应域名的A记录
# 并获取对应的 ZONE_ID 和 RECORDSET_ID

DOMAIN_NAME="XXXXXXX"
RECORDSET_ID="XXXXXXX"


# 一般来说用户名和账户名相同
USERNAME="XXXXXXX"
ACCOUNTNAME="XXXXXXX"
PASSWORD="XXXXXXX"

# 对应解析记录的 ZONE_ID、RECORDSET_ID和PROJECT_ID，其中PROJECT_ID可以在华为云APIexplorer中的云解析服务>recordset管理>showRecordSet中填写id后的调试结果中的请求头X-Project-Id看到
ZONE_ID="XXXXXXX"
PROJECT_ID="XXXXXXX"

REMOTE_RESOLVE=1

# 从网卡获取ip地址(填写网卡名)
# 并请根据实际情况填写sed行数

TARGET_IP=""

# 获取ip地址网址
