捲曲請求失敗

Question

我有這樣的代碼：

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, "http://www.infoempleo.com/"); 
curl_setopt($ch, CURLOPT_POST, false); 
//curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 
curl_setopt($ch, CURLOPT_COOKIEJAR,$cookie); 
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie); 
curl_setopt($ch, CURLOPT_HTTPGET ,true); 
curl_setopt($ch, CURLOPT_HEADER, false); 
curl_setopt($ch,CURLOPT_HTTPHEADER,array('HeaderName: HeaderValue')); 
    // curl_setopt($ch,CURLOPT_TIMEOUT,10); 
curl_setopt($ch, CURLOPT_REFERER, ''); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
$homepage = curl_exec($ch); 
var_dump($homepage); 

但就是不工作，它正在與google.com但與http://www.infoempleo.com/。 這段代碼有什麼問題？

我嘗試使用在線ping實用程序，如http://network-tools.com/，服務器沒有響應ping請求，但它們響應http標頭。 那麼我需要在cURL請求中設置什麼才能使其工作？

但此代碼的工作

$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_URL, $url); 

curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 

curl_setopt ($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 0); 
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie); 
curl_setopt ($ch, CURLOPT_REFERER, $url . "blog/wordpress/wp-login.php"); 

curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata); 
curl_setopt ($ch, CURLOPT_POST, 1); 
$result = curl_exec ($ch); 

怎麼樣？

Answer 1

它可能會限制用戶代理。嘗試改變

//curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 

與

curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
