商品变更通知
<h4><strong>简要描述：</strong></h4>
<p>商品信息变动通知
1.本接口为POST,验证回调sign不参与签名
2.接收到推送后,请返回字符串ok,否则视为不成功,将会按照时间阶梯延迟5|10|15|20|25分钟继续进行通知回调,最多回调5次。</p>
<h4><strong>签名算法（php demo）：</strong></h4>
<pre><code>/**
* 验证回调
* @param $post 请求参数
* @return bool
*/
public function verify($post)
{
$sign = $post[&#039;sign&#039;] ?? &#039;&#039;;
unset($post[&#039;sign&#039;]);
$data = [
&#039;id&#039; =&gt; $post[&#039;id&#039;],
&#039;time&#039; =&gt; $post[&#039;time&#039;],
];
ksort($data); //排序post参数
try {
$newsign = sha1($post[&#039;time&#039;] . json_encode($data, 256) . $this-&gt;config[&#039;pay_password&#039;]);//签名
} catch (\Throwable $e) {
}
return !empty($newsign) &amp;&amp; $newsign == $sign;
