SAE域名绑定设置服务器宕机时自动修改A记录并飞信通知

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:

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http://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。

monitorCallback.php,代码如下:

 $domain_id,
            'record_id' => $record_id,
            'sub_domain' => $sub_domain,
            'record_type' => 'A',
            'record_line' => $record_line,
            'ttl' => '600',
            'value' => $newIP
        );
        $dnspod = new dnspod();
        $response = $dnspod->api_call('Record.Modify', $data);
        if (isset($response['status']['code']) && $response['status']['code'] == 1) {
            $msg = $msg . $newIP . '(已切换)';
        } else {
            $msg = $msg . $newIP . '(切换失败，错误代码' . $response['status']['code'] . ')';
        }
    }
    //飞信通知
    require_once 'Fetion.class.php';
    $fetion = new PHPFetion($FetionNum, $FetionPwd);
    $result = $fetion->send($MobileNum, $msg);
    if (strpos($result, '短信发送成功!') || strpos($result, '发送消息成功!')) {
        $r = "成功。";
    } else {
        $r = "失败。";
    }
    $s = new SaeStorage();
    $content = $s->read($logStorDomain, $logName);
    $content = $content . $msg . '。飞信通知' . $r . '

    $s->write($logStorDomain, $logName, $content);
    // 处理完成
