php采集模拟点击伪造IP,伪造浏览器useragent伪造来源防反爬虫例子--

先上两个文件 index.php  一个curl.php

index.php是我们要采集的。以下是源码

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

$allow_ip = '192.168.1.100';
$allow_referer = 'http://www.amztool.cn';
$useragent=$_SERVER['HTTP_USER_AGENT'];
plog( 'client_ip='.$client_ip." || useragent=".$useragent.' ');
echo '<br>client_ip=';
echo $client_ip;
echo " || useragent=";
echo $useragent;

echo '<hr><br>';
// 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 '';
}

function plog($message){
    $file=__DIR__."/text.txt";

     if($f  = file_put_contents($file, $message."\r\n",FILE_APPEND)){// 这个函数支持版本(PHP 5) 打印到文件

        }
}

再上curl.php 这个文件是用来采集的执行文件

$ch = curl_init();
$curlurl = "http://www.amztool
