BS4：如何从 <script> 标记中的无效 json 中获取值答案

【问题描述】：

我正在尝试从此标签中获取 hlsUrl。

import json
import re

from bs4 import BeautifulSoup

html_doc = """
    <script>
      var modelData = {
        "hlsUrl": "null",
        "account": "1V2FO4K7ME78RV09VXNEC",
        "packageName": "null",
        isActive: false
      }
  </script>
"""

soup = BeautifulSoup(html_doc, "html.parser")
script_text = soup.select_one("script").string
model_data = re.search(r"modelData = ({.*?})", script_text, re.S).group(1)
print(json.loads(model_data)["account"])

但我收到此错误：

obj, end = self.scan_once(s, idx)
json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 5 column 9 (char 111)

我知道这是因为 isActive: false 导致它不是有效的 json

如何将其转换为有效的 json 或以其他方式获取 hlsUrl？

soup = BeautifulSoup(html_doc, "html.parser")
script_text = soup.select_one("script").string
model_data = re.search(r"modelData = ({.*?})", script_text, re.S).group(1)

model_data = re.sub(r"^\s*([^\s\"]+):", r'"\1":', model_data, flags=re.M)  # <-- fix `isActive:` to `"isActive":`

print(json.loads(model_data)["account"])

打印：

1V2FO4K7ME78RV09VXNEC
