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:
<?php $url = "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"; $ch2 = curl_init(); curl_setopt($ch2, CURLOPT_URL, $url); curl_setopt($ch2, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch2, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($ch2, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch2, CURLOPT_RETURNTRANSFER, TRUE); $texts = curl_exec($ch2); curl_close($ch2); //echo $texts; $pattern = '/"pics"(.+?)","reply"/is'; preg_match_all($pattern, $texts, $match); for($i=0;$i<count($match[0]);$i++){ $pattern2 = '/"rateContent":"(.+?)."reply"/is'; preg_match($pattern2, $match[0][$i], $matchcomments_only); echo "<p>".str_replace('","rateDate":"',' ',str_replace('","reply"','',str_replace('"rateContent":"','',$matchcomments_only[0])))."</p>"; $pattern3 = '/img.alicdn(.+?).jpg/is'; preg_match($pattern3, $match[0][$i], $matchpic_only); echo '<img src="http://'.$matchpic_only[0].'" width=120>'; } /*匹配一张图片 $pattern = '/"pics"(.+?)","position"/is'; preg_match_all($pattern, $texts, $matchpic); for($i=0;$i<count($matchpic[0]);$i++){ $pattern3 = '/img.alicdn(.+?).jpg/is'; preg_match($pattern3, $matchpic[0][$i], $matchpic_only); echo "<p>".$matchpic_only[0]."</p>"; }*/ /*匹配所有图片 $pattern = '/"pics"(.+?)","position"/is'; preg_match_all($pattern, $texts, $matchpic); for($i=0;$i<count($matchpic[0]);$i++){ $pics_str=str_replace('"pics":["//','',str_replace('"],"picsSmall":"","position"','',$matchpic[0][$i])); $arr = explode('","//',$pics_str); echo "<p>"; foreach($arr as $newstr){ echo '<img src=http://'.$newstr.' width=100 >'; } echo "</p>"; }*/ ?>
下面给大家介绍PHP抓取淘宝搜索商品列表实例
<?php header("Content-Type:text/html;charset=gbk"); include "Snoopy.class.php"; $snoopy = new Snoopy; $snoopy->fetch("http://s.taobao.com/search?spm=a230r.1.8.7.2NN4M7&q=%C7%EF%B6%AC%B4%F3%D2%C2&source=tbsy&refpid=420461_1006&discount_index=1&newpre=null&p4p_str=fp_midtop%3D0%26firstpage_pushleft%3D0&style=list&s=0#J_Filter"); $html=$snoopy->results; //说明:抓取网页使用的是 Snoopyphp 框架 也可以直接使用file_get_contents函数获取即可, //var_dump($html); preg_match_all('/<h3 class="summary">.*</a>/',$html,$result); //preg_match_all('/<divsid="([a-z0-9_]+)">([^<>]+)</div>/',$html,$result); var_dump($result); echo "<br>"; /* //循环读取数组 foreach($result as $key1){ foreach($key1 as $key => $val){ echo $key.$val; } } */
