我需要一个脚本来处理 HTTP 302 响应，并返回给定 URL 的真实链接。例如http://185.20.36.231:8080/stream/?channel=nettvinfo&stream=1mb&sp=pass1@&b=3&u=user1它应该返回http://185.20.36.233:8080/stream/?fw=true&route=at1_1&rule=null&sp=nettvplus&channel=nettvinfoint&stream=1mb&u=user1&b=3&player=http

我尝试了以下脚本，但由于某种原因，它不适用于这个特定的 URL。请帮忙。

    <?php
function getOriginalURL($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1");
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    $result = curl_exec($ch);
    $httpStatus = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);

    // if it's not a redirection (3XX), move along
    if ($httpStatus < 300 || $httpStatus >= 400)
        return $url;

    // look for a location: header to find the target URL
    if(preg_match('/location: (.*)/i', $result, $r)) {
        $location = trim($r[1]);

        // if the location is a relative URL, attempt to make it absolute
        if (preg_match('/^\/(.*)/', $location)) {
            $urlParts = parse_url($url);
            if ($urlParts['scheme'])
                $baseURL = $urlParts['scheme'].'://';

            if ($urlParts['host'])
                $baseURL .= $urlParts['host'];

            if ($urlParts['port'])
                $baseURL .= ':'.$urlParts['port'];

            return $baseURL.$location;
        }

        return $location;
    }
    return $url;
}
    $newurl=getOriginalURL("http://185.20.36.231:8080/stream/?channel=nettvinfo&stream=1mb&sp=pass1@&b=3&u=user1");
    print($newurl);
?>
