卷曲請求失敗

Question

我有這個代碼：

$ch = curl_init();  
curl_setopt($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);

但它不起作用，它可以與 google.com 一起使用，但不能與http://www.infoempleo.com/ 一起使用。 這段代碼有什么問題？

我嘗試了像http://network-tools.com/這樣的在線 ping 實用程序，但服務器沒有響應 ping 請求，但它們正在響應 http 標頭。 那么我需要在 cURL 請求中設置什么才能使其工作？

但是這段代碼有效

$ch = curl_init();
curl_setopt ($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);

如何 ？

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");

和

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");
