用godaddy实现ddns或服务器故障自动切换

#根据你自己的信息修改如下内容
domain="your_domain_here.com"   # 需更新的域名,比如iytc.net
name="@"                        # 需更新的A记录名称，比如要更新test.iytc.net，此处填写test
key="your key here"             # 你的godaddy Key
secret="your secret here"       # 你的godaddy Secret

currentIp=$1
 
headers="Authorization: sso-key $key:$secret"
 
 
result=$(curl -v -k -X GET -H "$headers" \
         "https://api.godaddy.com/v1/domains/$domain/records/A/$name")
 
 
dnsIp=$(echo $result | grep -oE "\b([0-9]{1,3}\.){3}[0-9]{1,3}\b")
#echo "dnsIp======="$dnsIp

 
 
if [ "$dnsIp" != "$currentIp" ]; then
        request='[{"data":"'$currentIp'","ttl":600}]'
        nresult=$(curl -i -k -v  -X PUT \
        -H "$headers" \
        -H "Content-Type: application/json" \
        -d $request "https://api.godaddy.com/v1/domains/$domain/records/A/$name")
