我如何从带有美丽汤的单词汤中获取特定的词组？

debugcn 发表于 Dev

我已经用 BeautifulSoup 对我的代码进行了排序，并得出了这个：

<bound method Tag.prettify of <script type="text/javascript">var LifeTimeStats = [{"Key":"Top 3","Value":"31"},{"Key":"Top 5s","Value":"36"},{"Key":"Top 3s","Value":"13"},{"Key":"Top 6s","Value":"27"},{"Key":"Top 12s","Value":"76"},{"Key":"Top 25s","Value":"58"},{"Key":"Score","Value":"99,788"},{"Key":"Matches Played","Value":"502"},{"Key":"Wins","Value":"9"},{"Key":"Win%","Value":"2%"},{"Key":"Kills","Value":"730"},{"Key":"K/d","Value":"1.48"}];</script>>

我试图从中获得特定的值“730”：

{"Key":"Kills","Value":"730"}

由于没有我可以排序的 HTML 标签。我不知道如何获得这个特定的价值。你有什么主意吗？

也许还有另一种解决方案......这是完整的代码：

#----WEB INPUT BASIC----

    #import bs4
    from urllib.request import urlopen as uReq
    from urllib.request import Request, urlopen
    from  bs4 import BeautifulSoup as soup


    #setting my url
    url = 'https://fortnitetracker.com/profile/psn/Rehgum'

    #making my https page work
    req = Request(url, headers={'User-Agent': 'Mozilla/5.0'})

    web_byte = urlopen(req).read()
    webpage = web_byte.decode('utf-8')
    urlopen(req).close()

    #html parsing
    page_soup = soup(webpage, "html.parser")

    lifetime = page_soup.findAll("script",{"type":"text/javascript"})

    stats = lifetime[3]

    specific = stats.prettify

    value = specific.text

    #from here there is just code to put that value in a .txt file

这只是您可以做什么的一个想法：

将 JS 代码提取到 Python 变量中。
进行正则表达式操作以提取变量的值。
“JSONify”这样的变量值。
提取您需要的数据。

作为摘录：

a = '''var LifeTimeStats = [{"Key":"Top 3","Value":"31"},{"Key":"Top 5s","Value":"36"},{"Key":"Top 3s","Value":"13"},{"Key":"Top 6s","Value":"27"},{"Key":"Top 12s","Value":"76"},{"Key":"Top 25s","Value":"58"},{"Key":"Score","Value":"99,788"},{"Key":"Matches Played","Value":"502"},{"Key":"Wins","Value":"9"},{"Key":"Win%","Value":"2%"},{"Key":"Kills","Value":"730"},{"Key":"K/d","Value":"1.48"}];'''

b = re.findall(r'var.*?=\s*(.*?);', a)[0]
c = json.loads(b)
