Question

我有2台网络服务器，服务器A＆amp;服务器B.两者都运行PHP5 + Apache + Ubuntu环境。

服务器A通过PHP中的cURL向服务器B发送请求。我想获取请求的源服务器域。据我所知，$_SERVER['REMOTE_ADDR']可以获取源服务器的IP（服务器A）。如果我想获得服务器A的域名，我该如何获得它？

P.S。服务器A托管多个域，因此在这种情况下反向IP解析不起作用。

以下是代码：

$data = array('user' => $user, 'pass' => $pass);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://ServerB/handler.php');
curl_setopt($ch, CURLOPT_PORT, 80);
curl_setopt($ch, CURLOPT_VERBOSE, 0); 
curl_setopt($ch, CURLOPT_HEADER, 0); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $data); 

$ans_xml = curl_exec($ch);

<?  
$data = array('user' => $user, 'pass' => $pass, 'appid' => 'pukeko');
$domain = $_SERVER["SERVER_NAME"]; // user the super global $_SERVER["SERVER_NAME"] or set it  manually to, ex: http://www.myserver.com 

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://ServerB/handler.php');
curl_setopt($ch, CURLOPT_PORT, 80);
curl_setopt($ch, CURLOPT_VERBOSE, 0); 
curl_setopt($ch, CURLOPT_HEADER, 0); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_REFERER, $domain); // USE CURLOPT_REFERER to set the referer 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $data); 

$ans_xml = curl_exec($ch);
?> 

<?
// ServerB - http://ServerB/handler.php
$referer = $_SERVER['HTTP_REFERER'];  // http://www.myserver.com 
?>

超级全局 $ _ SERVER [“SERVER_NAME”] 仅在您通过apache调用 scriptA 时才有效，例如：“ wget http://serverA/scritptA.php < /强>“

您还可以在帖子数据中发送$domain = $_SERVER["SERVER_NAME"]：

$domain = $_SERVER["SERVER_NAME"] $data = array('user' => $user, 'pass' => $pass, 'appid' => 'pukeko', 'icomefrom' => $domain);

并在http://ServerB/handler.php中获取：

$icomefrom = $_POST['icomefrom'];

这样你就不用担心假参赞了。

在上面的评论中，作为统计数据Pelshoff，您应该使用自定义HTTP标头：
