使用python从html文档中提取javascript变量值

import re
from bs4 import BeautifulSoup

# 读取HTML文件
with open('example.html', 'r') as file:
    html = file.read()

# 使用BeautifulSoup解析HTML文件
soup = BeautifulSoup(html, 'html.parser')

# 查找所有的<script>标签
scripts = soup.find_all('script')

# 遍历所有的<script>标签，查找JavaScript变量
for script in scripts:
    # 获取<script>标签中的文本内容
    script_text = script.string

    # 使用正则表达式查找JavaScript变量
    variable_pattern = re.compile(r'var\s+(\w+)\s*=\s*(.*?)\s*;')
    variables = variable_pattern.findall(script_text)

    # 输出找到的JavaScript变量及其值
    for variable in variables:
        print(f'{variable[0]}: {variable[1]}')
