试图在虚拟服务器上进行一些本地测试,问题是cURL返回了一个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,我得到一个命中.
如果我用http://dev.project尝试它,我会得到未知主机.

是否有curl_setopt选项只是为了使用主机名？我不确定我是否可以使用IP,因为服务器上有几个项目,或Apache会处理这个？

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：//在网址中预先设置)

Array
(
    [url] => http://dev.project?parm=1234
    [http_code] => 0
    [header_size] => 0

)

解决方法:

如果有人有这个问题,这是修复：

// 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);
