Question

这是我的代码：

soup_detail.find_all（“ script”，type =“ application / ld + json”）[0] .contents [0]

这是上面代码的输出：

'{“ @context”：“ http://schema.org”，“ @type”：“产品”， “ name”：“男士拖鞋，简约设计，铆钉装饰，时尚十足 “耐磨鞋”，“图片”：“”，“说明”：“材质：人造皮革”， “ brand”：{“ @type”：“事物”，“ name”：“”}，“ aggregateRating”：{ “ @type”：“ AggregateRating”，“ ratingValue”：“ 5”，“ reviewCount”：“ 1”}， “ offers”：{“ @type”：“ Offer”，“ availability”： “ http://schema.org/InStock”，“价格”：“ 10.99”，“ priceCurrency”：“美元” }}'

如何从此bs4.element.NavigableString中提取例如“ ratingValue”：“ 5”，“ reviewCount”：“ 1”？

预先感谢您的帮助。

Answer 1

j = '{ "@context": "http://schema.org", "@type": "Product", "name":"Men\'s Slippers Brief Design Rivet Decor All Match Fashion Wearable Shoes", "image":"", "description": "Material:Faux Leather", "brand":{ "@type": "Thing", "name": "" }, "aggregateRating": { "@type": "AggregateRating", "ratingValue": "5", "reviewCount": "1" }, "offers": { "@type": "Offer", "availability": "http://schema.org/InStock", "price": "10.99", "priceCurrency": "USD" } }'
j = json.loads(j)
print(j['@context'])
print(j['aggregateRating']['reviewCount'])
print(j['aggregateRating']['ratingValue'])
print(j.keys())
print(j.values())

输出

dict_keys(['@context', '@type', 'name', 'image', 'description', 'brand', 'aggregateRating', 'offers'])
dict_values(['http://schema.org', 'Product', "Men's Slippers Brief Design Rivet Decor All Match Fashion Wearable Shoes", '', 'Material:Faux Leather', {'@type': 'Thing', 'name': ''}, {'@type': 'AggregateRating', 'ratingValue': '5', 'reviewCount': '1'}, {'@type': 'Offer', 'availability': 'http://schema.org/InStock', 'price': '10.99', 'priceCurrency': 'USD'}])
