php – 如何重定向保留原始引用者字段？

我有以下PHP重定向脚本：

if ($country=="IL") { header('Location: http://iquality.itayb.net/index-he.html'); }
else { header('Location: http://iquality.itayb.net/index-en.html'); }

根据$country的值,这会将用户重定向到不同的页面.引荐者成为重定向页面本身.

如何保留原始引荐来源字段？

解决方法:

您不能使用标题(‘Referer：SOME_REFERER_URL’),因为浏览器无论如何都会覆盖它.

如果你拥有重定向的目标iquality.itayb.net,那么有几种方法可以做到这一点：

>在用户会话中保存引用者.

// in your first script save real referer to session
$_SESSION['REAL_REFERER'] = $_SERVER['HTTP_REFERER'];

// in the redirected script extract referer from session
$referer = '';
if (isset($_SESSION['REAL_REFERER'])) {
    $referer = $_SESSION['REAL_REFERER'];
    unset($_SESSION['REAL_REFERER']);
}
else {
    $referer = $_SERVER['HTTP_REFERER'];
}

>发送referer作为参数：

// in your first script
header('Location: http://iquality.itayb.net/index-he.html?referer=' . $_SERVER['HTTP_REFERER']);

// in your refered script extract from the parameter
$referer = '';
if (isset($_REQUEST['referer'])) {
    $referer = $_REQUEST['referer'];
}
else {
    $referer = $_SERVER['HTTP_REFERER'];
}

如果你想欺骗任何其他服务器,那么使用这样的东西：

$host = 'www.yourtargeturl.com';
$service_uri = '/detect_referal.php';
$vars ='additional_option1=yes&additional_option2=un';

$header = "Host: $host\r\n";
$header .= "User-Agent: PHP Script\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Referer: {$_SERVER['HTTP_REFERER']} \r\n";
$header .= "Content-Length: ".strlen($vars)."\r\n";
$header .= "Connection: close\r\n\r\n";

$fp = fsockopen("".$host,80, $errno, $errstr);
if (!$fp) {
  echo "$errstr ($errno)<br/>\n";
  echo $fp;
} else {
    fputs($fp, "POST $service_uri  HTTP/1.1\r\n");
    fputs($fp, $header.$vars);
    fwrite($fp, $out);

    while (!feof($fp)) {
        echo fgets($fp, 128);
    }
    fclose($fp);
}
