在现代商业中，供应链的协同运作至关重要。

快递物流查询API接口可以实现供应商、电商平台、物流企业和消费者之间的信息无缝对接，各方能够及时获取快递物流信息，从而更好地协调生产、销售和配送等环节，提高整个供应链的效率和效益，减少库存积压和缺货现象。

快递物流查询API接口具有良好的兼容性和可集成性，能够轻松地与电商平台、仓储管理系统、客户关系管理系统等各类企业应用系统进行集成，实现信息的互联互通，打造一体化的企业管理解决方案。

以下是用PHP调用快递物流查询API接口的代码示例：

<?php$appKey = "您的appKey";
$appSecret= "您的appSecret";$url = "https://api.shuxuntech.com/v1/express/query";
$method = "POST";$timestamp = getUnixTimestamp();
var_dump($timestamp);
$sign = hash('sha256',$appKey . $timestamp . $appSecret);
var_dump($sign);$headers = array();
array_push($headers, "Content-Type" . ":" . "application/x-www-form-urlencoded; charset=UTF-8");
array_push($headers, "appKey" . ":" . appKey);
array_push($headers, "timestamp" . ":" . timestamp);
array_push($headers, "sign" . ":" . sign);$no = "";
$code = "";
$tel = "";
$bodys = "no=" . $no . "&code=" . $code . "&tel=" . $tel;$curl = curl_init();
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_POSTFIELDS, $bodys);
curl_setopt($curl, CURLOPT_FAILONERROR, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);if (1 == strpos("$".$url, "https://")) {curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
}
var_dump(curl_exec($curl));function getUnixTimestamp () {list($s1, $s2) = explode(' ', microtime());return sprintf('%.0f',(floatval($s1) + floatval($s2)) * 1000);
}
