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, '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×tamp=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. 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.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

There are four main error types in PHP: 1.Notice: the slightest, will not interrupt the program, such as accessing undefined variables; 2. Warning: serious than Notice, will not terminate the program, such as containing no files; 3. FatalError: the most serious, will terminate the program, such as calling no function; 4. ParseError: syntax error, will prevent the program from being executed, such as forgetting to add the end tag.

In PHP, the difference between include, require, include_once, require_once is: 1) include generates a warning and continues to execute, 2) require generates a fatal error and stops execution, 3) include_once and require_once prevent repeated inclusions. The choice of these functions depends on the importance of the file and whether it is necessary to prevent duplicate inclusion. Rational use can improve the readability and maintainability of the code.

HTTP request methods include GET, POST, PUT and DELETE, which are used to obtain, submit, update and delete resources respectively. 1. The GET method is used to obtain resources and is suitable for read operations. 2. The POST method is used to submit data and is often used to create new resources. 3. The PUT method is used to update resources and is suitable for complete updates. 4. The DELETE method is used to delete resources and is suitable for deletion operations.
