使用php的curl类，检测socket5代理服务器可用性

设计初衷当然是用php curl bind不一个sokcet5去访问一个随机页面（公网）这个页面的功能就是通过一个md5来验证sokcet5服务器是否真的可用
A服务器通过 socket5发出http://xxxx/a.php?t=randkey
B服务器，echo md5($_GET['t'] . mykey);
A服务器拿到content以后也用相同算法算一个$resut看看是不是等于B服务器的echo值，如果一样，就是success 不一样就是failed

第一个文件curl.inc.php
<?php
class CurlRequest
{
private $ch=0;
/**
* Init curl session
*
* $params = array(‘url’ => ”,
* ’host’ => ”,
* ‘header’ => ”,

function __destruct(){

?>
第二个文件
<?php
include ‘curl.inc.php’;
$GLOBALS[‘curl’]=new CurlRequest;
function verify($proxy,$prot)
{
$key=rand(’1000000′,’9999999′);
$params = array(‘url’ => "http://xxxxx.com/a.php?md=$key", //自己找个服务器放个程序！
‘host’ => ‘help.dhgate.com’,
‘proxy’ => "$proxy:$prot",
‘proxyport’=>"$prot",
‘timeout’ =>10
);
$GLOBALS[‘curl’]->init($params);
$result=$GLOBALS[‘curl’]->exec();
if(trim($result[‘body’])==md5($key.‘my’))
return true;
else
return false;
}
echo verify(‘localhost’,’7777′);
?>
目标服务器的那个程序。。。
<?php
echo md5($_GET[‘md’].‘my’);
?>

verify 函数返回的true false标志socket5服务器是否可用！
curl_setopt($this->ch,CURLOPT_PROXYTYPE,CURLPROXY_SOCKS5); 这行话，是专门给socket5用的你要验证http proxy的也一样，删了这行就行了！
