我希望将 curl 设置为使用代理服务器。该 url 由 html 表单提供，这不是问题。没有代理它工作正常。我在这个网站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。谢谢你。

我从这里改编的波纹管代码http://www.webmasterworld.com/forum88/10572.htm但它返回有关第 12 行缺少 T_VARIABLE 的错误消息。

<?

$url = '$_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curl 通过代理返回没有内容

<?

$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;
?>

目前在 pelican-cement.com 上直播，但也无法正常工作。

更新：感谢您的所有帮助，我进行了上述更改。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;
?>

这是一个删除了您的错误的工作版本。

$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;

我已添加CURLOPT_PROXYUSERPWD以防您的任何代理需要用户名和密码。我设置CURLOPT_RETURNTRANSFER为1，这样数据就会返回给$curl_scraped_page变量。

我删除了第二个额外的curl_exec($ch);内容，这将停止返回变量。我将您的代理 IP 和端口合并为一个设置。

我也删除了CURLOPT_HTTPPROXYTUNNEL，CURLOPT_CUSTOMREQUEST因为它是默认设置。

如果您不希望返回标头，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);

有任何问题随时问，我cURL每天都在工作。

我已经解释了 CURL PROXY 所需的各种 CURL 选项的使用。

$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;

这是一个经过良好测试的功能，我将其用于我的项目，并附有详细的自我解释性评论

很多时候，80 以外的端口被服务器防火墙阻止，因此代码在 localhost 上似乎工作正常，但在服务器上却没有 

function get_page($url){

global $proxy;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
//curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_HEADER, 0); // return headers 0 no 1 yes
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return page 1:yes
curl_setopt($ch, CURLOPT_TIMEOUT, 200); // http request timeout 20 seconds
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // Follow redirects, need this if the url changes
curl_setopt($ch, CURLOPT_MAXREDIRS, 2); //if http server gives redirection responce
curl_setopt($ch, CURLOPT_USERAGENT,
    "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt"); // cookies storage / here the changes have been made
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // false for https
curl_setopt($ch, CURLOPT_ENCODING, "gzip"); // the page encoding

$data = curl_exec($ch); // execute the http request
curl_close($ch); // close the connection
return $data;
}
