CURL模拟IP访问-php

限制IP访问

<?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 '';
}
?>

CURL模拟 IP 访问

<?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://www.example.com/server.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;
?>

模拟session访问

<?php
header("Content-Type:text/html;charser=UTF-8");

function get_curl($url, $cookie = 0, $post = 0, $referer = 0, $header = 0, $ua = 0, $nobaody = 0)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
$klsf[] = "Accept:*/*";
$klsf[] = "Accept-Encoding:gzip,deflate,sdch";
$klsf[] = "Accept-Language:zh-CN,zh;q=0.8";
curl_setopt($ch, CURLOPT_HTTPHEADER, $klsf);
if ($post) {
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
}
if ($header) {
curl_setopt($ch, CURLOPT_HEADER, TRUE);
}

curl_setopt($ch, CURLOPT_COOKIE, $cookie);
if ($referer) {
if ($referer == 1) {
curl_setopt($ch, CURLOPT_REFERER, "http://m.qzone.com/infocenter?g_f=");
} else {
curl_setopt($ch, CURLOPT_REFERER, $referer);
}
}
if ($ua) {
curl_setopt($ch, CURLOPT_USERAGENT, $ua);
} else {
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Linux; U; Android 4.0.4; es-mx; HTC_One_X Build/IMM76D) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0');
}
if ($nobaody) {
curl_setopt($ch, CURLOPT_NOBODY, 1);//主要头部
//curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);//跟随重定向
}
curl_setopt($ch, CURLOPT_ENCODING, "gzip");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$ret = curl_exec($ch);
curl_close($ch);
return $ret;

} 

HTTPS中的POST请求

/* HTTPS请求　start */
    private function curl_post_https($url,$data){ // 模拟提交数据函数
        $curl = curl_init(); // 启动一个CURL会话
        curl_setopt($curl, CURLOPT_URL, $url); // 要访问的地址
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); // 对认证证书来源的检查
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 1); // 从证书中检查SSL加密算法是否存在
        curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); // 模拟用户使用的浏览器
        curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); // 使用自动跳转
        curl_setopt($curl, CURLOPT_AUTOREFERER, 1); // 自动设置Referer
        curl_setopt($curl, CURLOPT_POST, 1); // 发送一个常规的Post请求
        curl_setopt($curl, CURLOPT_POSTFIELDS, $data); // Post提交的数据包
        curl_setopt($curl, CURLOPT_TIMEOUT, 30); // 设置超时限制防止死循环
        curl_setopt($curl, CURLOPT_HEADER, 0); // 显示返回的Header区域内容
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // 获取的信息以文件流的形式返回
        $tmpInfo = curl_exec($curl); // 执行操作
        if (curl_errno($curl)) {
            echo 'Errno'.curl_error($curl);//捕抓异常
        }
        curl_close($curl); // 关闭CURL会话
        return $tmpInfo; // 返回数据，json格式
    }
    /* HTTPS请求　end */
