Use PHP to crawl product data from Tmall and Taobao

This article mainly introduces in detail the method of crawling Tmall and Taobao product data with PHP. It has certain reference value. Interested friends can refer to it

1. Idea

I recently made a website that crawled product information from Tmall and Taobao from the URL. First I looked at the mobile webpage and found that react was used. I didn’t know much about it and couldn’t do it, so I Consider crawling the data from the PC portal, but when crawling the URL to obtain the data, the price, inventory, etc. information is not obtained. After careful study, I found that another interface is requested asynchronously, but the interface requires a refer to obtain the data, so I A simple crawler is written in the following way, which is used to crawl the product preview and the price, inventory, etc. of the first category of the product.

2. The code to implement

is as follows:

function crawlUrl($url){
import('PhpQuery.Curl');
 $curl=new \Curl();
 $result = $curl->read($url);
 $content = mb_convert_encoding( $result['content'], 'UTF-8', 'UTF-8,GBK,GB2312,BIG5' );
 $myres=array();
 if(strrpos($url,'taobao.com')!=false) {
  //匹配是否下架
  if(strpos($content,'此宝贝已下架')!==false){
   return false;
  }
  preg_match("|itemId   : '(.*)'|isU", $content, $match);
  $item_id=$match[1];
  preg_match("|sellerId   : '(.*)'|isU", $content, $match);
  $sellet_id=$match[1];
  preg_match("|<title>(.*)</title>|isU",$content,$match);
  $title=$match[1];
  //价格库存信息
  $ch = curl_init();
  curl_setopt ($ch, CURLOPT_URL, &#39;https://detailskip.taobao.com/service/getData/1/p1/item/detail/sib.htm?itemId=&#39;.$item_id.&#39;&sellerId=&#39;.$sellet_id.&#39;&modules=dynStock,qrcode,viewer,price,duty,xmpPromotion,delivery,upp,activity,fqg,zjys,amountRestriction,couponActivity,soldQuantity,originalPrice,tradeContract&callback=onSibRequestSuccess&#39;);

  $myres[&#39;title&#39;]=str_replace(&#39;-淘宝网&#39;,&#39;&#39;,$title);

  $myres[&#39;act_price&#39;]=current($result[&#39;data&#39;][&#39;promotion&#39;][&#39;promoData&#39;]);

  $myres[&#39;stock&#39;]=$result[&#39;data&#39;][&#39;dynStock&#39;][&#39;stock&#39;];

  $myres[&#39;banners&#39;]=$images[1];
 }else{
  //匹配是否下架
  if(strpos($content,&#39;此宝贝已下架&#39;)!==false){
   return false;
  }
  $start=strpos($url,&#39;&id=&#39;);

  }

  $myres[&#39;title&#39;]=str_replace(&#39;-tmall.com天猫&#39;,&#39;&#39;,$title);

  $myres[&#39;price&#39;]=$result[&#39;defaultModel&#39;][&#39;itemPriceResultDO&#39;][&#39;priceInfo&#39;][$nowk][&#39;price&#39;];

 }
 return $myres;
}

The above code uses the phpquery library , but it is actually useless. Just use Curl. The specific crawled data can be viewed through parameters. The method does not distinguish between Taobao and Tmall links, but the premise is that it must be a PC-side link. In addition, the regular expression is not standardized, so it can Rewrite the regex yourself to match the data.
