php使用CURL抓取whois记录
示例： http://www.whois.net/whois/hotmail.com
何时在浏览器中打开，显示输出。
当使用curl调用时，它什么也不显示。
怎么了？我想返回整个页面结果，然后使用正则表达式检索 Expiration Date: 29-Mar-2015 00:00:00 行的数据。
$postfields= null;
$postfields["noneed"] = "";
$queryurl= "http://www.whois.net/whois/hotmail.com";
$results= getUrlContent($postfields, $queryurl);
echo $results;
function getUrlContent($postfields,$api_url)
{
if( !extension_loaded('curl') ){die('You need to load/activate the cURL extension (http://www.php.net/cURL).'); }
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $api_url); // set the url to fetch
curl_setopt($ch, CURLOPT_HEADER, 0); // set headers (0 = no headers in result)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // type of transfer (1 = to string)
curl_setopt($ch, CURLOPT_TIMEOUT, 10); // time to wait in seconds
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
$content = curl_exec($ch); // make the call
curl_close($ch);
return $content;
}
Example: http://www.whois.net/whois/hotmail.com
When open in browser, output is shown.
When using curl call, it show nothing.
What's wrong? I want to return whole page result, then use regular expression to retrieve data at Expiration Date: 29-Mar-2015 00:00:00 line.
$postfields= null;
$postfields["noneed"] = "";
$queryurl= "http://www.whois.net/whois/hotmail.com";
$results= getUrlContent($postfields, $queryurl);
echo $results;
function getUrlContent($postfields,$api_url)
{
if( !extension_loaded('curl') ){die('You need to load/activate the cURL extension (http://www.php.net/cURL).'); }
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $api_url); // set the url to fetch
curl_setopt($ch, CURLOPT_HEADER, 0); // set headers (0 = no headers in result)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // type of transfer (1 = to string)
curl_setopt($ch, CURLOPT_TIMEOUT, 10); // time to wait in seconds
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
$content = curl_exec($ch); // make the call
curl_close($ch);
return $content;
}

Whois.net 检查
用户代理。因此，在调用curl_exec之前将这些添加到您的函数中Whois.net checks
user agent. So add these to your function before you callcurl_exec您看到的错误与 whois.com 无关，它表明您尚未为 PHP 启用 cURL 模块。首先尝试启用 PHP cURL 模块。

The error you see is not related to whois.com, it shows you have not enabled cURL module for your PHP. Try enabling the PHP cURL module first.
