别的不多说了,我们一起来看一下怎么实现吧:
代码如下:
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("|(.*)|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');

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('|

preg_match_all('/
$myres['title']=str_replace('-淘宝网','',$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-$start-4);
}
preg_match("|(.*)|isU",$content,$match);
$title=$match[1];

//查询出图片信息
preg_match('|
- (.*)
preg_match_all('/
$myres['banners']=$images[1];
}
return $myres;
}
上述代码用到phpquery的库,但是其实没啥用,直接用Curl就行,具体爬取的数据可以穿参查看结果,方法不区分淘宝和天猫链接,但是前提是必须是PC端链接,另外正则写的不规范,所以可以自己重写正则来匹配数据。
