如何抓取<脚本文本/javascript>

Question

所以我试图弄清楚如何使用正则表达式抓取javascript标签，我认为这可能是最简单的方法。

标记如下所示：

<script type="text/javascript">
var spConfig=newApex.Config({
  "attributes": {
    "199": {
      "id": "199",
      "code": "legend",
      "label": "Weapons",
      "options": [
        {
          "label": "10",
          "priceInGame": "0",          
          "id": [
          ]
        },
        {
          "label": "10.5",
          "priceInGame": "0",          
          "id": [
          ]
        },
        {
          "label": "11",
          "priceInGame": "0",          
          "id": [
            "66659"
          ]
        },
        {
          "label": "11.5",
          "priceInGame": "0",          
          "id": [            
          ]
        },
        {
          "label": "12",
          "priceInGame": "0",          
          "id": [
          ]
        },
        {
          "label": "12.5",
          "priceInGame": "0",          
          "id": [           
          ]
        },
        {
          "label": "13",
          "priceInGame": "0",         
          "id": [
          ]
        },
        {
          "label": "4",
          "priceInGame": "0",          
          "id": [
          ]
        },
        {
          "label": "4.5",
          "priceInGame": "0",          
          "id": [
          ]
        },
        {
          "label": "5",
          "priceInGame": "0",         
          "id": [
          ]
        },
        {
          "label": "5.5",
          "priceInGame": "0",        
          "id": [
          ]
        },
        {
          "label": "6",
          "priceInGame": "0",         
          "id": [
          ]
        },
        {
          "label": "6.5",
          "priceInGame": "0",         
          "id": [
          ]
        },
        {
          "label": "7",
          "priceInGame": "0",         
          "id": [
          ]
        },
        {
          "label": "7.5",
          "priceInGame": "0",         
          "id": [
          ]
        },
        {
          "label": "8",
          "priceInGame": "0",          
          "id": [
            "66672"
          ]
        },
        {
          "label": "8.5",
          "priceInGame": "0",          
          "id": [
            "66673"
          ]
        },
        {
          "label": "9",
          "priceInGame": "0",          
          "id": [
          ]
        },
        {
          "label": "9.5",
          "priceInGame": "0",        
          "id": [
            "66675"
          ]
        }
      ]
    }
  },
  "weaponID": "66733",
  "chooseText": "Apex Legends",
  "Config": {
    "includeCoins": false,
  }
});
</script>

我想刮掉所有标签

我试图做的是：

        for nosto_sku_tag in bs4.find_all('script', {'type': 'text/javascript'}):
            try:
                test = re.findall('var spConfig = ({.*}?);', nosto_sku_tag.text.strip())
                print(test)
            except:  # noqa
                continue

但它只返回一个空值 []

所以我在这里问我能做些什么才能刮标签？

Answer 1

您需要使用 attr=value 或attrs={'attr': 'value'}语法指定属性。

https://www.crummy.com/software/BeautifulSoup/bs4/doc/#the-keyword-arguments

import json
import re
from bs4 import BeautifulSoup
if __name__ == '__main__':
    html = '''
<script type="text/javascript">
var spConfig=newApex.Config({
  "attributes": {
    "199": {
      "id": "199",
      "code": "legend",
      "label": "Weapons",
      "options": [
        { "label": "10", "priceInGame": "0", "id": [] },
        { "label": "10.5", "priceInGame": "0", "id": [] },
        { "label": "11", "priceInGame": "0", "id": [ "66659" ] },
        { "label": "7.5", "priceInGame": "0", "id": [] },
        { "label": "8", "priceInGame": "0", "id": ["66672"] }
      ]
    }
  },
  "weaponID": "66733",
  "chooseText": "Apex Legends",
  "taxConfig": {
    "includeCoins": false,
  }
});
</script>    
    '''
    soup = BeautifulSoup(html, 'html.parser')
    # this one works too
    # script = soup.find('script', attrs={'type':'text/javascript'})
    script = soup.find('script', type='text/javascript')
    js: str = script.text.replace('n', '')
    raw_json = re.search('var spConfig=newApex.Config(({.*}));', js, flags=re.MULTILINE).group(1)
    data = json.loads(raw_json)
    labels = [opt['label'] for opt in data['attributes']['199']['options']]
    print(labels)

输出：

['10', '10.5', '11', '7.5', '8'] ... some removed for brevity

如果您只是在 JSON 对象中查找整个行字段，请使用以下内容;

("label":) "([^"]+)",

然后，如果要返回实际值，只需使用
