京东联盟自动转链接测试代码，需求账户权限

下载sdk测试了半天，结果发现许多接口需要申请权限，要么就是没有流量，于是就作罢了，保留一段测试用程序备用吧。

<?php
// 京东联盟API配置
date_default_timezone_set("PRC");
$appKey = '';
$appSecret = '';
$siteId = '';
$skuId = '';

// 生成推广链接
function generateJdPromotionLink($skuId, $appKey, $appSecret, $siteId) {
    $method = 'jd.union.open.goods.promotiongoodsinfo.query';
    $timestamp = date('Y-m-d H:i:s');
    $v = '1.0';
    $signMethod = 'md5';

    // 请求参数
    $params = [
        'method' => $method,
        'app_key' => $appKey,
        'timestamp' => $timestamp,
        'v' => $v,
        'sign_method' => $signMethod,
        'param_json' => json_encode([
            'skuIds' => $skuId,
            'siteId' => $siteId,
        ]),
    ];

    // 生成签名
    ksort($params);
    $signString = $appSecret;
    foreach ($params as $key => $value) {
        $signString .= $key . $value;
    }
    $signString .= $appSecret;
    $sign = strtoupper(md5($signString));

    // 添加签名到参数
    $params['sign'] = $sign;

    // 请求API
    $apiUrl = 'https://api.jd.com/routerjson';
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $apiUrl);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params));

    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); // 忽略SSL主机验证
    $response = curl_exec($ch);

    if (curl_errno($ch)) {
        die("API请求失败: " . curl_error($ch));
    }
    curl_close($ch);

    // 解析结果
    $result = json_decode($response, true);

    // 调试信息
    echo "<pre>";
    print_r($result);
    echo "</pre>";

    // 检查结果
    if (isset($result['jd_union_open_goods_promotiongoodsinfo_query_responce']['result'])) {
        $promotionInfo = json_decode($result['jd_union_open_goods_promotiongoodsinfo_query_responce']['result'], true);
        if ($promotionInfo['code'] == 200 && !empty($promotionInfo['data']['promotionInfo']['promotionUrl'])) {
            return $promotionInfo['data']['promotionInfo']['promotionUrl'];
        } else {
            die("API返回错误: " . $promotionInfo['message']);
        }
    } else {
        die("API返回结果格式不正确");
    }
}

// 生成推广链接
$promotionUrl = generateJdPromotionLink($skuId, $appKey, $appSecret, $siteId);
