php curl 如何抓取淘宝商品页面?求大神回复。。感觉超难。

Jun 23, 2016 pm 02:28 PM

这是我写的curl抓取代码,抓取天猫商品也有用。但淘宝商品页却抓不了。

<?php$url = "http://item.taobao.com/item.htm?id=16396503658";$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_HEADER, false);curl_setopt($ch, CURLOPT_TIMEOUT, 20);curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);$ret = curl_exec($ch);curl_close($ch);echo $ret;?>
Copy after login

加了CURLOPT_FOLLOWLOCATION也没用。。求大神指导

淘宝描述动态加载 分析一下 取那个地址

怎么分析。。CURLOPT_FOLLOWLOCATION不是会自动跳到最终也没吗

不仅要有跳转,还需要传递 cookie
curl 仅能获取目标页面的 html 代码,并不能执行其中的 js 程序
而该页面的关键数据同时通过 js 产生的

。。。。。我现在连页面都抓不到
怎么存cookie

存储cookie有专门的属性
CURLOPT_COOKIEJAR

我试了下 http://item.taobao.com/item.htm?id=16396503658 根本打开了就是空白的你想怎么取?
你的商品ID是有问题的...
