對于限制了ip和來源的網站，使用正常的訪問方式是無法訪問的。本文將介紹一種方法，使用php的curl類實現模擬ip和來源，訪問那些限制了ip和來源的網站。
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 = 'http://www.survivalescaperooms.com';if($client_ip==$allow_ip && strpos($referer, $allow_referer)===0){ echo 'allow access';}else{ echo 'deny access';}// 獲取訪問者ipfunction getip(){ if(!empty($_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 $_SERVER['HTTP_REFERER']; } return '';}?>2.使用curl正常訪問
<?phpfunction doCurl($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($ch, CURLOPT_HTTPHEADER, array('CLIENT-IP: 模擬ip','X-FORWARDED-FOR: 模擬ip'));
完整代碼如下：
<?phpfunction doCurl($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$referer = 'http://www.survivalescaperooms.com/';$response = doCurl($url, $data, $header, $referer, 5);echo $response;?>返回 allow access
