SAE域名绑定之后，一般是用CNAME方式将域名绑定到应用中。但是有时候我们需要用到A记录（比如说根域名，虽然在DNSPOD上可以设置CNAME记录，但很可能会影响到MX记录），而SAE的IP地址经常改变，ping应用二级域名得到的IP没多久就失效了（前些天网站因此几天打不开都没发现，我用的是教育网，自己能打开，但是电信线路变了）。还好DNSPOD有个功能叫D监控，可以帮你监控网站能否正常打开。如果发现宕机，DNSPOD会用邮件、短信、微信等方式提醒你。这里用到的是它的另一个通知方式，那就是URL回调。
“通过DNSPod 提供的D监控 URL 回调功能，您可以让宕机或恢复信息提交到您指定的 URL 上，从而更加灵活地处理各种通知信息。”
我们可以通过宕机之后的URL回调取得相关参数，并通过DNSPOD API实现自动修改记录的功能，再通过飞信发送宕机通知。
代码在后面，先说设置方法：
设置方法
1.点此下载代码，修改其中的参数为你自己的。
2.将代码上传到网站。
3.在DNSPOD开启D监控，在通知设置中回调URL一栏填入monitorCallback.php的地址，如https://blog.gimhoy.com/monitorCallback.php?rHost=hipic.sinaapp.com.其中rHost是SAE的二级域名。并设置回调密钥。
4.Enjoy~
