How to set hostname using php curl for a specific ip
提问by Vishesh Joshi
Hi I have a server which has several virtual hosts set up on it.
嗨，我有一台服务器，上面设置了几个虚拟主机。
I wanted to make a curl request to this server's ip using php. Also I wanted to make this request to a specific hostname on the server's ip.
我想使用 php 向该服务器的 ip 发出 curl 请求。此外，我想向服务器 ip 上的特定主机名发出此请求。
Is there a way to do it?
有没有办法做到这一点？
A bit more elaboration : I want to make a curl requests between my servers using internal LAN, using their internal IP. The issue is that I have several sites hosted on this server. So when i make a curl request to the internal IP of the server.. something like (curl_init(xxx.xxx.xxx.xxx)), I want to be able to be tell apache to go to a particular folder pointed to by a virtual host. I hope that made the question a bit more clear.. – Vishesh Joshi 3 mins ago edit
更详细一点：我想使用内部 LAN 在我的服务器之间使用它们的内部 IP 发出 curl 请求。问题是我在这台服务器上托管了几个站点。因此，当我向服务器的内部 IP 发出 curl 请求时……类似于 (curl_init(xxx.xxx.xxx.xxx))，我希望能够告诉 apache 转到 a 指向的特定文件夹虚拟主机。我希望这能让问题更清楚一点.. – Vishesh Joshi 3 分钟前编辑

You can set the host header in the curl request:
您可以在 curl 请求中设置主机标头：
<?php
$ch = curl_init('XXX.XXX.XXX.XXX');
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: subdomain.hostname.com'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
echo curl_exec($ch);

For HTTPS sites use CURLOPT_RESOLVEwhich exists in every PHP version since PHP 5.5.
对于 HTTPS 站点，使用自 PHP 5.5 起CURLOPT_RESOLVE存在于每个 PHP 版本中的HTTPS 站点。
<?php
$ch = curl_init('https://www.example.com/');
// note: array used here
curl_setopt($ch, CURLOPT_RESOLVE, array(
"www.example.com:443:172.16.1.1",
));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
$result = curl_exec($ch);
Sample output:
示例输出：
* Added www.example.com:443:172.16.1.1 to DNS cache
* Hostname www.example.com was found in DNS cache
* Trying 172.16.1.1...

Base on Leigh Simpson, It works, but I need query string attach with it. That's what I work around:
基于 Leigh Simpson，它可以工作，但我需要附加查询字符串。这就是我的工作：
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://xxx.xxx.xxx.xxx/index.php?page=api&action=getdifficulty");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: subdomain.hostname.com'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
echo curl_exec($ch);
?>
