php curl模拟ip和来源进行访问 伪造IP 伪造来源访问
对于一些限制ip和来源访问的网站,使用正常的PHP CURL抓取访问是无法访问的。这里介绍一种使用php的curl类实现模拟ip和来源的方法,来突破那些限制ip和来源的网站。
1.构建一个限制ip和来源访问的页面,用于模拟限制情况
server.php
<?php
$client_ip = getip();
$referer = getreferer();
$allow_ip = '192.168.1.100';
$allow_referer = 'https://www.bnxb.com';
if($client_ip==$allow_ip && strpos($referer, $allow_referer)===0){
echo 'allow access';
}else{
echo 'deny access';
}
// 获取访问者ip
function getip(){
if(!empty($_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 $cip;
}
// 获取访问者来源
function getreferer(){
if(isset($_SERVER['HTTP_REFERER'])){
return $_SERVER['HTTP_REFERER'];
}
return '';
}
?>2.使用curl正常按正常情况进行访问
<?php
function doCurl($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;
}
// 调用
$url = 'https://www.bnxb.com/server.php';
$response = doCurl($url);
echo $response;
?>可以发现返回 deny access
3.使用curl模拟ip和来源进行访问
模拟来源
curl_setopt($ch, CURLOPT_REFERER, '来源');
模拟ip
curl_setopt($ch, CURLOPT_HTTPHEADER, array('CLIENT-IP: 模拟ip','X-FORWARDED-FOR: 模拟ip'));
模拟浏览器
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:39.0) Gecko/20100101 Firefox/39.0');
完整代码如下:
<?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, $timeout);
// 模拟来源
curl_setopt($ch, CURLOPT_REFERER, $referer);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:39.0) Gecko/20100101 Firefox/39.0');
$response = curl_exec($ch);
if($error=curl_error($ch)){
die($error);
}
curl_close($ch);
return $response;
}
// 调用
$url = 'https://www.bnxb.com/server.php';
$data = array();
// 伪造IP
$header = array(
'CLIENT-IP: 192.168.1.100',
'X-FORWARDED-FOR: 192.168.1.100'
);
// 伪造来源
$referer = 'https://www.bnxb.com/';
$response = doCurl($url, $data, $header, $referer, 5);
echo $response;
?>返回 allow access
成功访问,以上就是使用PHP CURL 伪造IP和来源进行访问的方法,希望对您有所帮助
