本篇文章扣丁學堂PHP培訓(xùn)小編帶讀者們一起來了解一下PHP爬取天貓和淘寶商品數(shù)據(jù)的方法,對PHP開發(fā)感興趣的小伙伴可以隨小編來看一下,文章中會有代碼列出供大家參考,一起來看一下吧。
別的不多說了,我們一起來看一下怎么實現(xiàn)吧:
代碼如下:
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,'此寶貝已下架')!==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]; //價格庫存信息 $ch = curl_init(); curl_setopt ($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); //查詢出圖片信息 preg_match('|<ul id="J_UlThumb" class="tb-thumb tb-clearfix">(.*)</ul>|isU', $content, $match); preg_match_all('/<img data-src="(.*?)" \//', $match[1], $images); $myres['title']=str_replace('-淘寶網(wǎng)','',$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,'此寶貝已下架')!==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'; //價格庫存信息 $ch = curl_init(); curl_setopt ($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; } $myres['title']=str_replace('-tmall.com天貓','',$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']; //查詢出圖片信息 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; }
上述代碼用到phpquery的庫,但是其實沒啥用,直接用Curl就行,具體爬取的數(shù)據(jù)可以穿參查看結(jié)果,方法不區(qū)分淘寶和天貓鏈接,但是前提是必須是PC端鏈接,另外正則寫的不規(guī)范,所以可以自己重寫正則來匹配數(shù)據(jù)。
