使用PHP一致获取Alexa网站排名

<?php
$siteUrl = 'https://example.com'; // 要获取排名的网站URL
$accessKey = 'your_access_key'; // 替换为你的Access Key
$secretKey = 'your_secret_key'; // 替换为你的Secret Key

// 构造请求参数
$params = array(
    'Action' => 'GetSiteRank',
    'Url' => $siteUrl,
    'Timestamp' => time(),
    'Nonce' => rand(10000, 99999),
    'SecretId' => $accessKey,
);

// 生成签名
ksort($params);
$signStr = '';
foreach ($params as $key => $value) {
    $signStr .= $key . '=' . $value . '&';
}
$signStr .= 'SecretKey=' . $secretKey;
$params['Signature'] = md5($signStr);

// 发送请求
$apiUrl = 'https://api.example.com'; // 替换为实际的API地址
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $apiUrl);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// 解析响应
$result = json_decode($response, true);
if ($result['code'] == 0) {
    $globalRank = $result['data']['global_rank'];
    $countryRank = $result['data']['country_rank'];
    echo "全球排名：$globalRank\n";
    echo "国家排名：$countryRank\n";
