php curl cookie 存取示例（标准采集程序）及伪装

php curl cookie 存取示例

好多人发来消息询问curl存取cookie文件的问题，杜工并不觉得这是个难点，因为只看手册就可以很容易把握。下面给个例子，看完后就全都明了了：

<?php$cookie_jar_index = dir(__FILE__)."/".'cookie.txt'; $url = "http://www.71j.cn/perl/login.pl";$params = "username=dudu&password=****";$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_jar_index);//curl_setopt($ch, CURLOPT_COOKIE, "fruit=apple; colour=red");//上面代码是直接传递cookie信息，而非文件curl_setopt($ch, CURLOPT_POST, 1);curl_setopt($ch, CURLOPT_POSTFIELDS, $params); //curl_setopt($ch, CURLOPT_NOBODY, 1);//这个不能打开，否则无法生成cookie文件ob_start();curl_exec($ch);curl_close($ch);ob_clean(); $url = "http://www.71j.cn/perl/myfavorites.pl";$ch2 = curl_init();curl_setopt($ch2, CURLOPT_URL, $url);curl_setopt($ch2, CURLOPT_COOKIEFILE, $cookie_jar_index);ob_start();curl_exec($ch2);curl_close($ch2);$rs = ob_get_contents(); //$rs就是返回的内容ob_clean(); print_r($rs); ?>

CURL IP伪装，更改IP头信息

<?php$ip = rand(1,255).".".rand(1,255).".".rand(1,255).".".rand(1,255)."";$ip='8.8.8.8';$ch = curl_init();curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);curl_setopt($ch,CURLOPT_HTTP_VERSION,CURL_HTTP_VERSION_1_1);curl_setopt($ch,CURLOPT_HTTPHEADER,array("Client_Ip: ".$ip."", "Real_ip: ".$ip."", "X_FORWARD_FOR:".$ip."", "X-forwarded-for: ".$ip."", "PROXY_USER: ".$ip.""));curl_setopt($ch, CURLOPT_URL,"http://192.168.1.99/11.php");echo curl_exec($ch);curl_close($ch);?>

高级篇：

CURLOPT_PROXY这个参数是否真的使用代理去请求数据？那他跟伪装IP的区别有哪些？下面我们做个试验。

curl_proxy_test.php

<?phpdefine ('IS_PROXY', true); //是否启用代理/* cookie文件 */$cookie_file = dirname ( __FILE__ ) . "/cookie_" . md5 ( basename ( __FILE__ ) ) . ".txt"; // 设置Cookie文件保存路径及文件名/*模拟浏览器*/$user_agent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.1.4322)";$proxy = "61.135.169.125";function vlogin($url, $data) { // 模拟登录获取Cookie函数$curl = curl_init (); // 启动一个CURL会话if (IS_PROXY) {//以下代码设置代理服务器//代理服务器地址curl_setopt ( $curl, CURLOPT_PROXY, $GLOBALS ['proxy'] );}// IP伪装$ip = rand(1,255).".".rand(1,255).".".rand(1,255).".".rand(1,255)."";  curl_setopt($curl, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:'.$ip, 'CLIENT-IP:'.$ip));  //构造IP  curl_setopt($curl, CURLOPT_REFERER, "http://www.nowamagic.net/ ");   //构造来路  curl_setopt($curl, CURLOPT_HEADER, 1);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, $GLOBALS ['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Referercurl_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_COOKIEJAR, $GLOBALS ['cookie_file'] ); // 存放Cookie信息的文件名称curl_setopt ( $curl, CURLOPT_COOKIEFILE, $GLOBALS ['cookie_file'] ); // 读取上面所储存的Cookie信息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 'Error ' . curl_error ( $curl );}curl_close ( $curl ); // 关闭CURL会话return $tmpInfo; // 返回数据}$params = "username=dudu&password=****";$result = vlogin("http://demo2.test.com/curl_proxy_test2.php",$params);echo $result;?>

curl_proxy_test2.php

<?phperror_reporting("E_ALL ^ (E_NOTICE | E_WARNING)");function getClientIp() {  if (!empty($_SERVER["HTTP_CLIENT_IP"]))  $ip = $_SERVER["HTTP_CLIENT_IP"];  else if (!empty($_SERVER["HTTP_X_FORWARDED_FOR"]))  $ip = $_SERVER["HTTP_X_FORWARDED_FOR"];  else if (!empty($_SERVER["REMOTE_ADDR"]))  $ip = $_SERVER["REMOTE_ADDR"];  else  $ip = "err";return $ip;  }echo "<br />IP: " . getClientIp() . "<br />";  print_r($_SERVER);  ?>

执行http://demo2.test.com/curl_proxy_test.php

输出内容为：Error couldn't connect to host

表明你必须要有台代理服务器才能完成操作。说到伪装跟代理的区别时，伪装会被识破的，只有使用匿名代理才能达到真正代理的效果。
