Detailed explanation of the steps to crawl Tmall and Taobao product data with PHP (with code)

This time I will bring you a detailed explanation of the steps for crawling Tmall and Taobao product data with php (with code). What are the precautions for php to crawl Tmall and Taobao product data. The following is the actual combat. Let’s take a look at the case.

1. Ideas

I recently made a website that crawled product information from Tmall and Taobao from the URL. I first looked at the mobile web page and found that it was used. React, I don’t know much about it and I can’t do it, so I considered crawling the data from the PC portal. However, when crawling the URL to obtain the data, the price, inventory, etc. information was not obtained. After careful study, I found that another interface was requested asynchronously. However, the interface needs to use refer to obtain data, so I wrote a simple crawler in the following way 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, 'https://detailskip.taobao.com/service/getData/1/p1/item/detail/sib.htm?itemId='.$item_id.'&sellerId='.$sellet_id.'&modules=dynStock,qrcode,viewer,price,duty,xmpPromotion,delivery,upp,activity,fqg,zjys,amountRestriction,couponActivity,soldQuantity,originalPrice,tradeContract&callback=onSibRequestSuccess');
  $opt[CURLOPT_HEADER]=false;
  $opt[CURLOPT_CONNECTTIMEOUT]=15;
  $opt[CURLOPT_TIMEOUT]=300;
  $opt[CURLOPT_AUTOREFERER]=true;
  $opt[CURLOPT_USERAGENT]='Mozilla/5.0 (Windows NT 6.1) AppleWebKit/536.11 (KHTML, like Gecko) Chrome/20.0.1132.47 Safari/536.11';
  curl_setopt_array($ch,$opt);
  curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt ($ch,CURLOPT_REFERER,$url);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
  $out_put=curl_exec ($ch);
  curl_close ($ch);
  $res=str_replace('onSibRequestSuccess(',"",$out_put);
  $res=rtrim($res,');1');
  $result=json_decode($res,true);
  //查询出图片信息
  preg_match('|<ul id="J_UlThumb" class="tb-thumb tb-clearfix">(.*)</ul>|isU', $content, $match);
  preg_match_all('/<img src="(.*?)" \//', $match[1], $images);
  $myres['title']=str_replace('-淘宝网','',$title);
  $myres['price']=current($result['data']['originalPrice']);
  $myres['act_price']=current($result['data']['promotion']['promoData']);
  $myres['stock']=$result['data']['dynStock']['stock'];
  $myres['banners']=$images[1];
 }else{
  //匹配是否下架
  if(strpos($content,'此宝贝已下架')!==false){
   return false;
  }
  $start=strpos($url,'&id=');
  $item_id=substr($url,$start+4,12);
  if(!is_numeric($item_id)){
   $start=strpos($url,'?id=');
   $end=strpos($url,'&spm');
   $item_id=substr($url,$start+4,$end-$start-4);
  }
  preg_match("|<title>(.*)</title>|isU",$content,$match);
  $title=$match[1];
  $myurl='https://mdskip.taobao.com/core/initItemDetail.htm?cachedTimestamp=1500562177777&queryMemberRight=true&cartEnable=true&offlineShop=false&addressLevel=2&itemId='.$item_id.'&tryBeforeBuy=false&isAreaSell=false&tmallBuySupport=true&isPurchaseMallPage=false&household=false&isForbidBuyItem=false&service3C=false&isRegionLevel=false&showShopProm=false&isSecKill=false&sellerPreview=false&isUseInventoryCenter=false&isApparel=true&callback=setMdskip&timestamp=1500562172109&isg=AiUlDZFWmP/sMgVurQSILU3Ytet/Zdis&isg2=Ajk51JIhRFqKzxmiNPP6dkYxSKXT7iySkzSTeVtu9WDf4ll0o5Y9yKdyEtHu';
  //价格库存信息
  $ch = curl_init();
  curl_setopt ($ch, CURLOPT_URL, $myurl);
  $opt[CURLOPT_HEADER]=false;
  $opt[CURLOPT_CONNECTTIMEOUT]=15;
  $opt[CURLOPT_TIMEOUT]=300;
  $opt[CURLOPT_AUTOREFERER]=true;
  $opt[CURLOPT_USERAGENT]='Mozilla/5.0 (Windows NT 6.1) AppleWebKit/536.11 (KHTML, like Gecko) Chrome/20.0.1132.47 Safari/536.11';
  curl_setopt_array($ch,$opt);
  curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt ($ch,CURLOPT_REFERER,$url);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
  $out_put=curl_exec ($ch);
  curl_close ($ch);
  $res = mb_convert_encoding( $out_put, 'UTF-8', 'UTF-8,GBK,GB2312,BIG5' );
  $res=str_replace('setMdskip',"",$res);
  $res=str_replace('(',"",$res);
  $res=str_replace(')',"",$res);
  $result=json_decode($res,true);
  $nowk="";
  $nowstore="";
  foreach($result['defaultModel']['inventoryDO']['skuQuantity'] as $k=>$val){
   $nowk=$k;
   $nowstore=$val;
   break;
  }
  $myres['title']=str_replace('-tmall.com天猫','',$title);
  $myres['price']=$result['defaultModel']['itemPriceResultDO']['priceInfo'][$nowk]['price'];
  $myres['act_price']=isset($result['defaultModel']['itemPriceResultDO']['priceInfo'][$nowk]['suggestivePromotionList'])?$result['defaultModel']['itemPriceResultDO']['priceInfo'][$nowk]['suggestivePromotionList']:$result['defaultModel']['itemPriceResultDO']['priceInfo'][$nowk];
  $myres['stock']=$result['defaultModel']['inventoryDO']['totalQuantity']?$result['defaultModel']['inventoryDO']['totalQuantity']:$nowstore['quantity'];
  //查询出图片信息
  preg_match('|<ul id="J_UlThumb" class="tb-thumb tm-clear">(.*)</ul>|isU',$content, $match);
  preg_match_all('/<img src="(.*?)" \//',$match[1],$images);
  $myres['banners']=$images[1];
 }
 return $myres;
}

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

I believe you have mastered the method after reading the case in this article. For more exciting information, please pay attention to other related articles on the php Chinese website!
