解析带有漂亮汤汁的JS

提问

我有一些页面用漂亮的汤解析.但是我有js代码：

<script type="text/javascript">   


var utag_data = {
            customer_id   : "_PHL2883198554", 
            customer_type : "New",
            loyalty_id : "N",
            declined_loyalty_interstitial : "false",
            site_version  : "Desktop Site",
            site_currency: "de_DE_EURO",
            site_region: "uk",
            site_language: "en-GB",


            customer_address_zip : "",
            customer_email_hash :  "",
            referral_source :  "",
            page_type : "product",
            product_category_name : ["Lingerie"],
            product_category_id :[jQuery("meta[name=defaultParent]").attr("content")],
            product_id : ["5741462261401"],
            product_image_url : ["http://images.urbanoutfitters.com/is/image/UrbanOutfitters/5741462261401_001_b?$detailmain$"],
            product_brand : ["Pretty Polly"],
            product_selling_price : ["20.0"],
            promo_id : "6",
            product_referral : ["WOMENS-SHAPEWEAR-LINGERIE-SOLUTIONS-EU"],
            product_name : ["Pretty Polly Shape It Up Tummy Shaping Camisole"],
            is_online_only : true,
            is_back_in_stock : false
}
</script>

如何从此输入中获取一些值？
我是否应该像处理文本一样使用此示例？我的意思是将其写入一些变量并拆分,然后获取一些数据？

谢谢

最佳答案

一旦您通过脚本获得了文本

js_text = soup.find('script', type="text/javascript").text

例如.然后,您可以使用regex查找数据,我敢肯定有一种更简单的方法可以做到这一点,但是regex也不应该那么困难.

import re
regex =  re.compile('\n^(.*?):(.*?)$|,', re.MULTILINE) #compile regex
js_text = re.findall(regex, js_text) #  find first item @ new line to : and 2nd item @ from : to the end of the line or , 
js_text = [jt.strip() for jt in js_text] #  to strip away all of the extra white space.

这将以name | value | name2 | value2 …的顺序返回名称和值的列表,您以后可以将其弄乱或转换为字典.
