本文介绍了一种使用PHP通过CURL抓取网页内容并伪造IP地址的方法。具体包括生成随机IP地址的函数Rand_IP()及抓取网页内容的函数Curl()。此方法通过设置HTTP头中的X-FORWARDED-FOR和CLIENT-IP字段实现IP地址的伪造。

curl伪造ip

//随机IP
function Rand_IP(){

    $ip2id= round(rand(600000, 2550000) / 10000); //第一种方法，直接生成
    $ip3id= round(rand(600000, 2550000) / 10000);
    $ip4id= round(rand(600000, 2550000) / 10000);
    //下面是第二种方法，在以下数据中随机抽取
    $arr_1 = array("218","218","66","66","218","218","60","60","202","204","66","66","66","59","61","60","222","221","66","59","60","60","66","218","218","62","63","64","66","66","122","211");
    $randarr= mt_rand(0,count($arr_1)-1);
    $ip1id = $arr_1[$randarr];
    return $ip1id.".".$ip2id.".".$ip3id.".".$ip4id;
}

//抓取页面内容
function Curl($url){
        $ch2 = curl_init();
        $user_agent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.66 Safari/537.36";//模拟windows用户正常访问
        curl_setopt($ch2, CURLOPT_URL, $url);
        curl_setopt($ch2, CURLOPT_TIMEOUT, 10);
        curl_setopt($ch2, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:'.Rand_IP(), 'CLIENT-IP:'.Rand_IP()));
//追踪返回302状态码，继续抓取
        curl_setopt($ch2, CURLOPT_HEADER, true); 
        curl_setopt($ch2, CURLOPT_RETURNTRANSFER, true); 
        curl_setopt($ch2, CURLOPT_FOLLOWLOCATION, true);

        curl_setopt($ch2, CURLOPT_NOBODY, false);
        curl_setopt($ch2, CURLOPT_REFERER, 'http://www.baidu.com/');//模拟来路
        curl_setopt($ch2, CURLOPT_USERAGENT, $user_agent);
        $temp = curl_exec($ch2);
        curl_close($ch2);
        return $temp;
}
