如何通过代理使用 CURL？

我希望将curl设置为使用代理服务器。URL由html表单提供，这不是问题。没有代理，它工作正常。我在这个和其他网站上找到了代码，但它们不起作用。任何帮助找到正确的解决方案将不胜感激。我觉得波纹管很接近，但我错过了一些东西。谢谢。

我从这里改编的波纹管代码 http://www.webmasterworld.com/forum88/10572.htm 但它返回了一条错误消息，说明第12行缺少T_VARIABLE。

<?

$url = '$_POST[1]';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 0);
curl_setopt($ch, CURLOPT_PROXY, '66.96.200.39:80');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST,'GET');
curl_setopt ($ch, CURLOPT_HEADER, 1)
curl_exec ($ch); 
$curl_info = curl_getinfo($ch);
curl_close($ch);
echo '<br />';
print_r($curl_info);
?>

波纹管是从卷曲到代理返回任何内容

<?

$proxy = "66.96.200.39:80";
$proxy = explode(':', $proxy);
$url = "$_POST[1]";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXY, $proxy[0]);
curl_setopt($ch, CURLOPT_PROXYPORT, $proxy[1]);
curl_setopt($ch, CURLOPT_HEADER, 1);

$exec = curl_exec($ch);

echo curl_error($ch);
print_r(curl_getinfo($ch));
echo $exec;
?>

目前 pelican-cement.com 上线，但也不起作用。

更新：感谢您的帮助，我做了上述更改。现在它只返回一个空白屏幕。

<?

$url = $_POST['1'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 0);
curl_setopt($ch, CURLOPT_PROXY, '66.96.200.39:80');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST,'GET');
curl_setopt ($ch, CURLOPT_HEADER, 1);
curl_exec ($ch); 
$curl_scraped_page = curl_exec($ch);
curl_close($ch);

echo $curl_scraped_page;
?>

这是一个删除了错误的工作版本。

$url = 'http://dynupdate.no-ip.com/ip.php';
$proxy = '127.0.0.1:8888';
//$proxyauth = 'user:password';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
//curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$curl_scraped_page = curl_exec($ch);
curl_close($ch);

echo $curl_scraped_page;

我已经添加了以防您的任何代理需要用户名和密码。我设置为1，以便数据将返回到变量。CURLOPT_PROXYUSERPWDCURLOPT_RETURNTRANSFER$curl_scraped_page

我删除了第二个额外的，这将停止返回变量。我将您的代理IP和端口合并到一个设置中。curl_exec($ch);

我也删除了，因为它是默认值。CURLOPT_HTTPPROXYTUNNELCURLOPT_CUSTOMREQUEST

如果不希望返回标头，请注释掉。CURLOPT_HEADER

要禁用代理，只需将其设置为 null。

curl_setopt($ch, CURLOPT_PROXY, null);

任何问题都可以随时提出，我每天都在工作。cURL

我已经解释了使用卷曲代理所需的各种卷曲选项。

$url = 'http://dynupdate.no-ip.com/ip.php';
$proxy = '127.0.0.1:8888';
$proxyauth = 'user:password';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);         // URL for CURL call
curl_setopt($ch, CURLOPT_PROXY, $proxy);     // PROXY details with port
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth);   // Use if proxy have username and password
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5); // If expected to call with specific PROXY type
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);  // If url has redirects then go to the final redirected URL.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);  // Do not outputting it out directly on screen.
curl_setopt($ch, CURLOPT_HEADER, 1);   // If you want Header information of response else make 0
$curl_scraped_page = curl_exec($ch);
curl_close($ch);

echo $curl_scraped_page;
