我正在尝试使用 Cloudflare API v4 在我的服务器上设置 DDNS。但我是编写文件的新手.sh。我希望在单个.sh文件中更新多个DNS记录。
我从互联网上得到了一个脚本(script1.sh(：
NEW_IP=`curl -s http://ipv4.icanhazip.com`
CURRENT_IP=`cat /Users/foo/Desktop/cloudflare/current_ip.txt`
if [ "$NEW_IP" = "$CURRENT_IP" ]
then
echo "No Change in IP Adddress"
else
curl -X PUT "https://api.cloudflare.com/client/v4/zones/{zone_id}/dns_records/{dns_record_id}"
-H "X-Auth-Email: {my_email}"
-H "X-Auth-Key: {global_api_key}"
-H "Content-Type: application/json"
--data '{"type":"A","name":"{domain_name}","content":"'$NEW_IP'","ttl":1,"proxied":true}'
echo $NEW_IP > /Users/foo/Desktop/cloudflare/current_ip.txt
fi
上述脚本适用于单个 DNS 记录更新，而不是像下面 (script2.sh( 那样的多记录更新：
NEW_IP=`curl -s http://ipv4.icanhazip.com`
CURRENT_IP=`cat /Users/foo/Desktop/cloudflare/current_ip.txt`
if [ "$NEW_IP" = "$CURRENT_IP" ]
then
echo "No Change in IP Adddress"
else
#domain-one
curl -X PUT "https://api.cloudflare.com/client/v4/zones/{zone_id_for_domain_one}/dns_records/{dns_record_id_for_domain_one_record_one}"
-H "X-Auth-Email: {my_email}"
-H "X-Auth-Key: {global_api_key}"
-H "Content-Type: application/json"
--data '{"type":"A","name":"domain-one.com","content":"'$NEW_IP'","ttl":1,"proxied":true}'
curl -X PUT "https://api.cloudflare.com/client/v4/zones/{zone_id_for_domain_one}/dns_records/{dns_record_id_for_domain_one_record_two}"
-H "X-Auth-Email: {my_email}"
-H "X-Auth-Key: {global_api_key}"
-H "Content-Type: application/json"
--data '{"type":"A","name":"subdomain.domain-one.com","content":"'$NEW_IP'","ttl":1,"proxied":true}'
#domain-two
curl -X PUT "https://api.cloudflare.com/client/v4/zones/{zone_id_for_domain_two}/dns_records/{dns_record_id_for_domain_two_record}"
-H "X-Auth-Email: {my_email}"
-H "X-Auth-Key: {global_api_key}"
-H "Content-Type: application/json"
--data '{"type":"A","name":"domain-two.com","content":"'$NEW_IP'","ttl":1,"proxied":true}'
echo $NEW_IP > /Users/foo/Desktop/cloudflare/current_ip.txt
fi
你能帮忙解释和解决问题吗？请告诉我剧本有什么问题。谢谢！
[编辑]我按sh /Users/foo/Desktop/script-name.sh运行一次，对于第一个示例(script1.sh(，还可以;对于第二个示例(script2.sh(，返回-bash: fork: Resource temporarily unavailable。由于我使用像cron这样的自动运行脚本，因此结果相同。
每个curl请求完成，需要添加&或&&才能继续以下功能。
更多解释在这里。
NEW_IP=`curl -s http://ipv4.icanhazip.com`

在浏览了许多关于这个主题的帖子之后，我最终从许多帖子中获取了部分内容，并确定了以下内容。
下面将遍历数组"dnsrecords"中的条目，并使用计算机的当前外部地址更新每个条目。
在此处查看更多信息，在此处以 cronjob 身份运行。
