用PHP抓取淘宝商品的用户晒单评论+图片实例，

为什么想起来做这个功能？是因为前段时间在做一个淘客网站的时候，想到是否能抓取到淘宝商品的买家秀呢？经过一番折腾发现，淘宝商品用户评价信息是通过Ajax来调取的，通过嗅探网址发现，评论数据的请求接口是：

https:<span>//</span><span>rate.tmall.com/list_detail_rate.htm?itemId=524394294771&spuId=341564036&sellerId=100414600&order=3&currentPage=1&append=0&content=1&tagId=&posi=&picture=1&callback=jsonp2339</span>

其实上面很多参数也很容易理解，itemId是商品的ID，currentPage是当前页，picture为1时显示有图的评价，既然是抓取买家秀，那么picture参数一定要为1了。

如果你直接去访问上面的接口时，会得到如下图所示的请求结果：

看到请求结果是jsonp格式我就蛋碎了，我不知道如何去解析，但是换种思路，直接用PHP的正则去解析也未尝不可嘛，通过尝试，已经正确的能够解析到评论内容和买家秀的图片内容，如图：

效果不错，代码实现了评论内容的抓取、买家秀图片的抓取，代码奉上：

<?<span>php

    $pattern3 = '/img.alicdn(.+?).jpg/is';
    preg_match($pattern3, $matchpic[0][$i], $matchpic_only);
    echo "<p>".$matchpic_only[0]."</p>";
}</span><span>*/</span>

    $arr = explode('","//',$pics_str);
