Question

我已经进行了一些研究，但似乎找不到任何有关是否有可能从URL检索JSON Schema数据之类的信息。无论如何，我刚刚在查看产品时发现的一个例子是：

https://www.reevoo.com/p/panasonic-nn-e271wmbpq

    <script class="microdata-snippet" type="application/ld+json">
{
  "@context": "http://schema.org/",
  "@type": "Product",
  "name": "PANASONIC NN-E271WMBPQ",
  "image": "https://images.reevoo.com/products/3530/3530797/550x550.jpg?fingerprint=73ed91807dac7eb8f899757a348c735446d0a1fe&gravity=Center"


    ,"category": {
      "@type": "Thing",
      "name": "Microwave",
      "url": "https://www.reevoo.com/browse/product_type/microwaves"
    }



    ,"description": "Auto weight programs will automatically calculate the cooking time, once the weight has been entered. Acrylic lining makes cleaning easy, simply wipe after use. Child lock provides extra security to prevent little fingers interfering with the programming of the oven. \nAll our compact microwave ovens are packed with flexible features to make everyday cooking simple. Auto weight programs will automatically calculate the cooking time, once the weight has been entered. Acrylic lining makes cleaning easy, simply wipe after use. Child lock provides extra security to prevent little fingers interfering with the programming of the oven."



    ,"aggregateRating": {
      "@type": "AggregateRating",
      "ratingValue": "8.7",
      "ratingCount": 636,
      "worstRating": "1",
      "bestRating": "10"
    }

}
</script>

那么有可能提取说说评分数据吗？

预先感谢

Answer 1

import json

然后是代码中的下一个：

microdata_content = response.xpath('//script[@type="application/ld+json"]/text()').extract_first()
microdata = json.loads(microdata_content)

ratingValue = microdata["aggregateRating"]["ratingValue"]

抓取LD JSON数据
