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 http://www.webmasterworld.com/forum88/10572.htm 改编的波纹管代码,但它返回关于第 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);
?>
以下来自curl through proxy returns no content
<?
$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。
<?

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;
我添加了 CURLOPT_PROXYUSERPWD
,以防您的任何代理需要用户名和密码。我将 CURLOPT_RETURNTRANSFER
设置为 1,以便将数据返回到 $curl_scraped_page
变量。
我删除了第二个额外的 curl_exec($ch);
,它将停止返回变量。我将您的代理 IP 和端口合并为一个设置。
我还删除了 CURLOPT_HTTPPROXYTUNNEL
和 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);
如有任何问题,请随时提出,我每天都与 cURL
一起工作。
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;

已修复在 php 脚本文件中声明代理设置的帖子问题。
$proxy = '10.172.123.1:80'; curl_setopt($cSession, CURLOPT_PROXY, $proxy); // PROXY details with port
这是一个经过良好测试的功能,我将其用于我的项目,并附有详细的自我解释性评论
很多时候,80 以外的端口被服务器防火墙阻止,因此代码在 localhost 上似乎工作正常,但在服务器上却没有
function get_page($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,

return $data;
