PHP CURL本地可以采集服务器上不能采集解决办法

php CURL本地可以采集服务器上不能采集解决办法，今天采集一个站，在本机上写好代码，发到网站服务器上确采集不到数据。这里分析，会不会是目标站对网站做了防采集。

网上搜了下解决办法，这里用PHP CURL伪造IP和来源测试看看。代码如下。

 

//随机IP
function Rand_IP(){

    $ip2id= round(rand(600000, 2550000) / 10000); //第一种方法，直接生成
    $ip3id= round(rand(600000, 2550000) / 10000);
    $ip4id= round(rand(600000, 2550000) / 10000);
    //下面是第二种方法，在以下数据中随机抽取
    $arr_1 = array("218","218","66","66","218","218","60","60","202","204","66","66","66","59","61","60","222","221","66","59","60","60","66","218","218","62","63","64","66","66","122","211");
    $randarr= mt_rand(0,count($arr_1)-1);
    $ip1id = $arr_1[$randarr];
    return $ip1id.".".$ip2id.".".$ip3id.".".$ip4id;
}

//抓取页面内容
function Curl($url){
        $ch2 = curl_init();
        $user_agent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (Khtml, like Gecko) Chrome/29.0.1547.66 Safari/537.36";//模拟windows用户正常访问
        curl_setopt($ch2, CURLOPT_URL, $url);
        curl_setopt($ch2, CURLOPT_TIMEOUT, 10);
        curl_setopt($ch2, CURLOPT_HTTPHEADER, array(‘X-FORWARDED-FOR:‘.Rand_IP(), ‘CLIENT-IP:‘.Rand_IP()));
//追踪返回302状态码，继续抓取
        curl_setopt($ch2, CURLOPT_HEADER, true); 
        curl_setopt($ch2, CURLOPT_RETURNTRANSFER, true); 
        curl_setopt($ch2, CURLOPT_FOLLOWLOCATION, true);

        curl_setopt($ch2, CURLOPT_NOBODY, false);
        curl_setopt($ch2, CURLOPT_REFERER, ‘http://www.chinaobd2.com/‘);//模拟来路
        curl_setopt($ch2, CURLOPT_USERAGENT, $user_agent);
        $temp = curl_exec($ch2);
        curl_close($ch2);
        return $temp;
}

php curl伪造来源ip和来路refer实例代码2：

<?php

$postData = array(
    "user" => "root",
    "pwd"  => "123456"
);

$headerIp = array(
    ‘CLIENT-IP:88.88.88.88‘,
    ‘X-FORWARDED-FOR:88.88.88.88‘,
);

$refer = ‘http://www.chinaobd2.com‘;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, ‘http://localhost/phpdemo/test.php‘);

//伪造来源refer
curl_setopt($ch, CURLOPT_REFERER, $refer);
//伪造来源ip
curl_setopt($ch, CURLOPT_HTTPHEADER, $headerIp);

//提交post传参
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
//...各种curl属性参数设置
$out_put = curl_exec($ch);
curl_close($ch);
var_dump($out_put);

以上代码我在chinaobd2.com网站测试，可行。遇到类似问题，大家可以参考一下。
