关于抓取网站数据，出现302重定向！

目标网站：http://www.dltm.net/webtmq/free/free_query.php
第一步：输入商标号，提交（post抓起）

第二步：点击商标号

第三步：需要抓取的数据

前两步均已实现抓取，但抓取最后一步时老是出现302重定向，导致数据抓取不到。
相关代码：

//第一步define(TARGET_URL,'http://www.dltm.net/webtmq/free/free_query.php');define(REFFER_URL,'http://www.dltm.net');$url=TARGET_URL;$ch=curl_init($url);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//返回结果存放在变量中，而不是默认的直接输出curl_setopt($ch, CURLOPT_HEADER, 0);curl_setopt($ch, CURLOPT_REFERER, REFFER_URL);$result= curl_exec($ch);//保存输出的页面到$result中curl_close($ch);preg_match_all('<input type="hidden" name="ip" value="(.*)">',$result,$rs);//第二步$fields_post = array(	'ip'=>$rs[1][0],	'textarea_explain'=>'%B2%E9%D1%AF%C8%AB%B2%BF%C0%E0%B1%F0',	'tm_lb'=> '0',	'tm_key'=>'8437927',	'tm_key_item'=>'tm_zch',	'query_mode'=>'1');$fields_string='';foreach($fields_post as $key => $value){    $fields_string .= $key . '=' . $value . '&';}$fields_string = rtrim($fields_string,'&');define(TARGET_URL1,'http://www.dltm.net/webtmq/free/free_res.php');define(REFFER_URL1,'http://www.dltm.net/webtmq/free/free_res.php');$url=TARGET_URL1;$ch=curl_init($url);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//返回结果存放在变量中，而不是默认的直接输出curl_setopt($ch, CURLOPT_HEADER, 0);curl_setopt($ch, CURLOPT_REFERER, REFFER_URL1);curl_setopt($ch,CURLOPT_POST,1);//以POST方式提交curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);$result= curl_exec($ch);//保存输出的页面到$result中curl_close($ch);//第三步preg_match_all('<a href="(.*)" target="detail">',$result,$res);$url = 'http://www.dltm.net/webtmq/free/'.$res[1][0];$ch=curl_init($url);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//返回结果存放在变量中，而不是默认的直接输出curl_setopt($ch, CURLOPT_HEADER, 0);curl_setopt($ch, CURLOPT_REFERER, REFFER_URL1);$result= curl_exec($ch);//保存输出的页面到$result中curl_close($ch);print_r($result);exit;//这一步得不到数据

可以自己copy一下代码运行一下，第三步数据得不到，大神能帮我看看么，如果能得到数据，请贴出你的源码，非常感谢！！！

回复讨论(解决方案)

增加
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");

增加
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");

不行啊，打印curl_getinfo($ch)

Array ( [url] => http://www.dltm.net/webtmq/free/free_detail.php?ip=7f6179b25de2974b0e0b33d01c2fef18&class_id=25&id=10309774 [content_type] => text/html [http_code] => 302 [header_size] => 440 [request_size] => 193 [filetime] => -1 [ssl_verify_result] => 0 [redirect_count] => 0 [total_time] => 0.094 [namelookup_time] => 0 [connect_time] => 0.047 [pretransfer_time] => 0.047 [size_upload] => 0 [size_download] => 0 [speed_download] => 0 [speed_upload] => 0 [download_content_length] => -1 [upload_content_length] => 0 [starttransfer_time] => 0.094 [redirect_time] => 0 [certinfo] => Array ( ) [redirect_url] => http://www.dltm.net/webtmq/free/free_query.php )

怎么不可以呢？
以注册号 8437927 为例
新建一文件 cookie.txt，执行代码

$cookie = realpath('cookie.txt'); //这是增加的//第一步define('TARGET_URL','http://www.dltm.net/webtmq/free/free_query.php');define('REFFER_URL','http://www.dltm.net');$url=TARGET_URL;$ch=curl_init($url);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//返回结果存放在变量中，而不是默认的直接输出curl_setopt($ch, CURLOPT_HEADER, 0);curl_setopt($ch, CURLOPT_REFERER, REFFER_URL);curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie); //这是增加的curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie); //这是增加的$result= curl_exec($ch);//保存输出的页面到$result中curl_close($ch);preg_match_all('<input type="hidden" name="ip" value="(.*)">',$result,$rs); //第二步$fields_post = array(    'ip'=>$rs[1][0],    'textarea_explain'=>'%B2%E9%D1%AF%C8%AB%B2%BF%C0%E0%B1%F0',    'tm_lb'=> '0',    'tm_key'=>'8437927',    'tm_key_item'=>'tm_zch',    'query_mode'=>'1'); $fields_string='';foreach($fields_post as $key => $value){    $fields_string .= $key .

谢谢，刚接触curl，cookie位置少放了
问题已解决，结贴！！！！
