DNSPOD的API申请地址：https://support.dnspod.cn/Kb/showarticle/tsid/227/

完整的请求地址为：https://www.dwhd.org/dnspod_v2.php?code=(API ID)&token=(API Token)&domain_id=(域名ID)&record_id=(解析ID)&sub_domain[域名解解析名]&record_type=[域名解析类型]&record_line=[域名解析线路]&value=[域名解析地址]

强制赋值变量为：

code，token，domain_id，record_id

可选变量为：

sub_domain，record_type，record_line，value

当变量sub_domain为空时，PHP自动赋值为：『routeos』

当变量record_type为空时，php自动赋值为：『A』

当变量record_line为空时，PHP自动赋值为：『默认』

当变量value为空时，php自动获取当前请求的IP为其值

<?php

$realip      = getIP();
$code        = $_GET['code'];
$token       = $_GET['token'];
$domain_id   = $_GET['domain_id'];
$record_id   = $_GET['record_id'];
$sub_domain  = $_GET['sub_domain'];
$value       = $_GET['value'];
$record_type = $_GET['record_type'];
$record_line = $_GET['record_line'];

if (empty($code))  { exit('code empty.'); }

$ip = checkIP($code, $token, $domain_id, $record_id);
if (empty($ip)) { exit('ip empty.'); }
if ($ip == $value) { exit("IP一致."); }
