说起来做这个功能还真是一时好奇。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://rate.tmall.com/list_detail_rate.htm?itemid=524394294771&spuid=341564036&sellerid=100414600&order=3¤tpage=1&append=0&content=1&tagid=&posi=&picture=1&callback=jsonp2339
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:
