php - cURL 关于虚拟主机命名的本地开发网络问题

Question

尝试在虚拟服务器上进行一些本地测试，问题是 cURL 返回 http_code => 0

我认为这与我的虚拟主机命名有关。

虚拟主机名:dev.project

cURL 请求正在添加 http://

如果我从命令行 ping: dev.project，就会成功。如果我用 http://dev.project 试试我得到了未知的主机。

是否有一个 curl_setopt 选项只是为了使用主机名？我不确定我是否可以使用该 IP，因为服务器上有多个项目，或者 Apache 会处理这个吗？

这是我尝试过的:

$request_url  = 'dev.project';
$request_args = 'parm=1234';
$user_agent   = 'Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.151 Safari/534.16';

$ch = curl_init();

// set curl options (GET)       
curl_setopt($ch, CURLOPT_URL, $request_url.'?'.$request_args);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
//curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
//curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
//curl_setopt($ch, CURLOPT_FAILONERROR, TRUE);
//curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
//curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie.txt");
//curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");
//curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // CHANGE THIS TO TRUE

// Set curl options (POST)
//curl_setopt($ch, CURLOPT_URL, $request_url);
//curl_setopt($ch, CURLOPT_POST, TRUE);
//curl_setopt($ch, CURLOPT_POSTFIELDS, $request_args);
//curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
//curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
//curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
//curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie.txt");
//curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");
//curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);

$response = curl_exec($ch); 
echo "<pre>".print_r($response,true)."</pre><br />\n"; // nothing is returned
print_r(curl_getinfo($ch));

curl_close($ch); 

来自 curl_getinfo() 的响应:(注意:http://在 url 中预先设置)

如果有人遇到这个问题，这里是解决方法:

// This is your Virtual Hosts name
$request_host   = 'dev.project'; 

// This is the IP
$request_url    = '192.168.0.1';

$headers = array("Host: ".$request_host);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);     
curl_setopt($ch, CURLOPT_URL, $request_url.'?'.$request_args);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
