从零开始学习PHP对接京东工业平台API接口，掌握订单状态查询技巧！

<?php
// 接口地址
$url = "https://api.jd.com/routerjson";

// 开发者密钥和密钥
$app_key = "your_app_key";
$app_secret = "your_app_secret";

// 接口方法和参数
$method = "jingdong.order.detail.search";
$timestamp = date('Y-m-d H:i:s');
$v = "2.0";
$format = "json";
$page = 1;
$page_size = 10;

// 生成签名
$sign_str = $app_secret . "app_key" . $app_key . "format" . $format . "method" . $method . "page" . $page . "page_size" . $page_size . "timestamp" . $timestamp . "v" . $v . $app_secret;
$sign = strtoupper(md5($sign_str));

// 请求参数
$params = array(
    'app_key' => $app_key,
    'format' => $format,
    'method' => $method,
    'timestamp' => $timestamp,
    'v' => $v,
    'sign' => $sign,
    'page' => $page,
    'page_size' => $page_size
);

// 发送HTTP请求
$options = array(
    CURLOPT_URL => $url,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => http_build_query($params),
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_SSL_VERIFYPEER => false,
    CURLOPT_SSL_VERIFYHOST => false
);

$ch = curl_init();
curl_setopt_array($ch, $options);
$result = curl_exec($ch);
curl_close($ch);

// 输出接口返回的数据
echo $result;
?>
