问题:使用 BeautifulSoup 获取表格内容

我正在尝试使用本网站的以下 python 代码检索表格内容:https://whalewisdom.com/filer/hillhouse-capital-advisors-ltd#tabholdings_tab_link

stat_table = soup.find_all('table', id_ = 'current_holdings_table', class_ = "table table-bordered table-striped table-hover")

但是当我使用 len(stat_table) 时,它返回的值为零,表明无法从网站上检索到任何内容。有谁知道我哪里出错了?感谢您的帮助。

解答

您看到的数据是通过 JavaScript 从另一个 URL 加载的。要加载数据,您可以使用以下示例:

import json
import requests


url = 'https://whalewisdom.com/filer/holdings?id=hillhouse-capital-advisors-ltd&q1=-1&type_filter=1,2,3,4&symbol=&change_filter=&minimum_ranking=&minimum_shares=&is_etf=0&sc=true&sort=current_mv&order=desc&offset=0&limit=25'
data = json.loads(requests.get(url).text)

# uncomment this to print all data:
# print(json.dumps(data, indent=4))

for row in data['rows']:
    print('{:<5} {:<50} {:<15} {:<15}'.format(row['symbol'], row['name'], row['current_shares'], row['current_mv']))
