问题:

I am working on a project that involves fetching pages with cURL or file_get_contents. The problem is that when i try to echo the html fetched, the output seem to be different from the original page, not all images show up. Please i would like to know if there is a solution. My code

    <?php
    //Get the url
    $url = "http://www.google.com";

    //Get the html of url
    function get_data($url) 
    { 
       $ch = curl_init();
       $timeout = 5;
       //$userAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US)AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.X.Y.Z Safari/525.13.";
       $userAgent = "IE 7 – Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30)";
      curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
      curl_setopt($ch, CURLOPT_FAILONERROR, true);
      curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
      curl_setopt($ch, CURLOPT_AUTOREFERER, true);
      curl_setopt($ch, CURLOPT_TIMEOUT, 10);
      curl_setopt($ch,CURLOPT_URL,$url);
      curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
      curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
      $data = curl_exec($ch);
      curl_close($ch);
      return $data;

    }

    $html = file_get_contents($url);
    echo $html;
?>

Thanks

回答1:

You should use <base> to specify a base url for all relative links:

If you curl http://example.com/thisPage.html then add a base tag in your echoed output of ''. This should technically be in the <head>, but this will work:

echo '<base href="http://example.com/" />';
echo $html;

Live example w <base> is broken w/o <base>

Use this

    //Get the html of url
    function get_data($url) 
    { 
       $ch = curl_init();
       $timeout = 5;
       //$userAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US)AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.X.Y.Z Safari/525.13.";
       $userAgent = "IE 7 – Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30)";
      curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
      curl_setopt($ch, CURLOPT_FAILONERROR, true);
      curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
      curl_setopt($ch, CURLOPT_AUTOREFERER, true);
      curl_setopt($ch, CURLOPT_TIMEOUT, 10);
      curl_setopt($ch,CURLOPT_URL,$url);
      curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
      curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
      $data = curl_exec($ch);
      curl_close($ch);
      return $data;

    }

$parse = parse_url($url);
$count =  "http://".$parse['host'].dirname($parse['path'])."//";

$page = str_replace("<head>", "<head>\n<base href=\"" . $count . "\" />", $page);
$page = str_replace("<HEAD>", "<head>\n<base href=\"" . $count . "\" />", $page);
echo $page;
?>
