订单异步回调
<h4><strong>简要描述：</strong></h4>
<p>订单异步回调接口</p>
<p>1.验证回调sign不参与签名
2.接收到推送之后，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>
<h3>签名算法（php demo）：</h3>
<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;]);
//卡密和物流信息 回调不签名
if (isset($post[&#039;card_list&#039;])) {
unset($post[&#039;card_list&#039;]);
}
if (isset($post[&#039;express_list&#039;])) {
unset($post[&#039;express_list&#039;]);
}
ksort($post); //排序post参数
try {
$newsign = sha1($post[&#039;time&#039;] . json_encode($post, 256) . $this-&gt;config[&#039;pay_password&#039;]);//签名
} catch (\Throwable $e) {
}
return !empty($newsign) &amp;&amp; $newsign == $sign;
}</code></pre>
