PHP curl模拟ip和来源进行访问

模拟来源 ip 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’));

<?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);

    $response = curl_exec($ch);

    if($error=curl_error($ch)){
        die($error);
    }

    curl_close($ch);

    return $response;

}




// 调用
$url = 'http://wx.newmiracle.cn/dsc.php';
$data = array();

// 设置IP
$header = array(
    'CLIENT-IP: 192.168.1.100',
    'X-FORWARDED-FOR: 192.168.1.100'
);

// 设置来源
$referer = 'http://www.csdn.net/';

$response = doCurl($url, $data, $header, $referer, 5);

echo $response;
?>

dsc.php代码

<?php

$client_ip = getip();
$referer = getreferer();

$allow_ip = '192.168.1.100';
$allow_referer = 'http://www.csdn.net';

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 '';
}

?>

不出意料 最终返回allow access
