阿里云域名云解析服务（DNS）API接口PHP封装
目前互联网上提供免费的域名托管服务的厂家很多，如阿里云/万网、腾讯云、CloudFlare、华为云等等，我们将域名托管到这些云解析DNS服务商后，虽然服务商都提供了控制台用于域名及解析记录的管理，但是有时候如果我们需要自己实现DDNS动态域名解析等一些基于官网API接口能力的功能，就需要使用到官网提供的API能力，本文将针对阿里云/万网的API接口，通过PHP封装了常用的函数类，用于托管域名、记录集等的管理。
本文旨在帮助开发者快速使用集成华为云云解析服务（DNS）的API接口，实现对域名（Zone）和解析记录（Record Set）的自动化管理，如域名托管、记录添加及修改等。
下面是PHP实现的API封装类，代码如下：
/**
* 阿里云域名服务、域名DNS解析管理实现类文件
* 主要实现
* 1、阿里云账号下的注册域名清单查询、域名信息查询、DS配置查询、NS查询及修改
* 2、阿里云账号下的DNS解析的域名的A、AAA、CNAME等记录的增删改查等操作
* DNS文档地址：https://api.aliyun.com/api-tools/demo/Alidns/87dd2c5a-bb87-4269-8bb1-6e021be52123
* 域名文档地址：https://api.aliyun.com/document/Domain/2018-01-29/overview
* 基于自定义封装API调用接口协议
* 调用方法：AliDomainDNS::Obj()->QueryDomainList($Param);
* 引用或者使用本文，请注明来源：楚狐在线- https://chuhu.org

下面提供一个简单的API调用示例，如下：
# 自己账户下的域名列表
$rtn = AliDomainDNS::Obj()->QueryDomainList()
print_r($rtn);
# 获取指定主域名的所有解析记录列表
$rtn = AliDomainDNS::Obj()->DescribeDomainRecords("mydomain.com");
print_r($rtn);
通过这个PHP封装类，我就可以用自己的域名，在自己的家庭网络设备如NAS上实现家里宽带的动态域名解析了，您可以创建一个ddns.php文件，核心代码如下：
//引入前面的类文件
require_once($_SERVER['DOCUMENT_ROOT'].'/AliDomainDNS-inc.php');
#获取当前客户端的ip
$REMOTE_ADDR = $_SERVER['REMOTE_ADDR'];
//IPv4地址更新
if(filter_var($REMOTE_ADDR, FILTER_VALIDATE_IP, FILTER_FLAG_IPV4))
{
AliDomainDNS::Obj()->ModifyDynamicDNS("ddns","example.com",$REMOTE_ADDR,"A");
}
//IPv6地址更新
if(filter_var($REMOTE_ADDR, FILTER_VALIDATE_IP, FILTER_FLAG_IPV6))
{
AliDomainDNS::Obj()->ModifyDynamicDNS("ddns","example.com",$REMOTE_ADDR,"AAAA");
}
