SAE域名綁定之后，一般是用CNAME方式將域名綁定到應用中。但是有時候我們需要用到A記錄（比如說根域名，雖然在DNSPOD上可以設置CNAME記錄，但很可能會影響到MX記錄），而SAE的IP地址經常改變，ping應用二級域名得到的IP沒多久就失效了（前些天網站因此幾天打不開都沒發現，我用的是教育網，自己能打開，但是電信線路變了）。還好DNSPOD有個功能叫D監控，可以幫你監控網站能否正常打開。如果發現宕機，DNSPOD會用郵件、短信、微信等方式提醒你。這里用到的是它的另一個通知方式，那就是URL回調“通過DNSPod 提供的D監控 URL 回調功能，您可以讓宕機或恢復信息提交到您指定的 URL 上，從而更加靈活地處理各種通知信息。”

我們可以通過宕機之后的URL回調取得相關參數，并通過DNSPOD API實現自動修改記錄的功能，再通過飛信發送宕機通知。

代碼在后面,先說設置方法:

1.點此下載代碼，修改其中的參數為你自己的。

2.將代碼上傳到網站。

3.在DNSPOD開啟D監控，在通知設置中回調URL一欄填入monitorCallback.php的地址，如http://blog.gimhoy.com/monitorCallback.php?rHost=hipic.sinaapp.com.其中rHost是SAE的二級域名。并設置回調密鑰。
