php – 使用HTTP-AUTH重定向？

我一直在使用cURL,作为第二个例子：
Sending basic authentication information via form

不幸的是,当我这样做时,实际的URL(显示在浏览器URL栏中)仍然是原始PHP的URL,而不是我正在浏览的目标.

这是我到目前为止所得到的：

<?php

$user = "xyz";
$pass = "abc";
$userpass = $user . ":" . $pass;

$url = "http://website/directory/";
$ch = curl_init();
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_USERPWD,$userpass);
$result = curl_exec($ch);
$httpcode = curl_getinfo($ch,CURLINFO_HTTP_CODE);
curl_close($ch);

if($httpcode == 200){
    header("Authorization: Basic " . base64_encode($userpass));
    echo $result;
}else{
    header("Location: http://website/login.php");
}

?>

我也试过更换上面的尾端：

if($httpcode == 200){
    header("Authorization: Basic " . base64_encode($userpass));
    header("Location: http://website/directory/");
}else{
    header("Location: http://website/login.php");
}

但那失败了;它重定向到http://website.xyz/directory,但它没有通过用户/通行证,我在到达时会收到服务器的登录信息.

从技术上讲,以下工作.但是,我更喜欢比在HREF中传递user / pass更优雅的解决方案：

header("Location: http://" . $userpass . "website/directory/");
