如何在php中利用curl對ip進行模擬?很多新手對此不是很清楚,為了幫助大家解決這個難題,下面小編將為大家詳細講解,有這方面需求的人可以來學習下,希望你能有所收獲。
1.設置頁面限制ip和來源訪問
server.php
<?php $client_ip = getip(); $referer = getreferer(); $allow_ip = '192.168.1.100'; $allow_referer = 'https://www.jb51.net'; if($client_ip==$allow_ip && strpos($referer, $allow_referer)===0){ echo 'allow access'; }else{ echo 'deny access'; } // 獲取訪問者ip function getip(){ if(!empty($_SERVER['HTTP_CLIENT_IP'])){ $cip = $_SERVER['HTTP_CLIENT_IP']; }elseif(!empty($_SERVER['HTTP_X_FORWARDED_FOR'])){ $cip = $_SERVER['HTTP_X_FORWARDED_FOR']; }elseif(!empty($_SERVER['REMOTE_ADDR'])){ $cip = $_SERVER['REMOTE_ADDR']; }else{ $cip = ''; } return $cip; } // 獲取訪問者來源 function getreferer(){ if(isset($_SERVER['HTTP_REFERER'])){ return $_SERVER['HTTP_REFERER']; } return ''; } ?>
2.使用curl正常訪問
<?php function doCurl($url, $data=array(), $header=array(), $timeout=30){ $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HTTPHEADER, $header); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data)); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_TIMEOUT, $timeout); $response = curl_exec($ch); if($error=curl_error($ch)){ die($error); } curl_close($ch); return $response; } // 調用 $url = 'http://www.example.com/server.php'; $response = doCurl($url); echo $response; ?>
返回 deny access
3.使用curl模擬ip和來源進行訪問
模擬來源
curl_setopt($ch, CURLOPT_REFERER, '來源');
模擬ip
curl_setopt($ch, CURLOPT_HTTPHEADER, array('CLIENT-IP: 模擬ip','X-FORWARDED-FOR: 模擬ip'));
完整代碼如下:
<?php function doCurl($url, $data=array(), $header=array(), $referer='', $timeout=30){ $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HTTPHEADER, $header); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data)); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_TIMEOUT, $timeout); // 模擬來源 curl_setopt($ch, CURLOPT_REFERER, $referer); $response = curl_exec($ch); if($error=curl_error($ch)){ die($error); } curl_close($ch); return $response; } // 調用 $url = 'http://www.example.com/server.php'; $data = array(); // 設置IP $header = array( 'CLIENT-IP: 192.168.1.100', 'X-FORWARDED-FOR: 192.168.1.100' ); // 設置來源 $referer = 'https://www.jb51.net/'; $response = doCurl($url, $data, $header, $referer, 5); echo $response; ?>
