#[必填]请在上方填写你的CLoudXNS的API KEY和SECRET KEY.
$DDNS="home.xxxx.com"
#[必填]请在上方填写你的域名，比如myhome.xxx.com
#请确保所填域名在账号内存在，否则会返回40x错误
$UPTIME=59
#[可选]检查更新的时间间隔（秒）
#API调用有频率限制，不建议设置过短间隔
#如果不需要循环检查更新（比如手动添加计划任务），请注释或填-1
$CHECKURL="http://ip.3322.org/"
#[可选]用于检查外网ip是否更新过的网址，减少API调用频率
#注释或填-1将不检查是否已经更新，直接提交ip更新请求
#$LOGFILE="./ddns.log"
#[可选]用于记录日志的文件路径*.log,注释掉将不保存日志
#配置结束
