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://m.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$referer = 'http://m.survivalescaperooms.com/';$response = doCurl($url, $data, $header, $referer, 5);echo $response;?>返回 allow access
