我如何从 barchart.com 中抓取这些股票代码？

Question

我正在尝试使用 Beautiful Soup 从该页面抓取股票代码列表：https://www.barchart.com/options/most-active/stocks

我的代码 returns 很多 HTML 来自页面，但我无法使用 CTRL+F 找到任何股票代码。如果有人能让我知道如何访问这些，我将不胜感激！

代码：

from bs4 import BeautifulSoup as bs
import requests
headers = {'user-agent': "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.141 Safari/537.36"}

url = "https://www.barchart.com/options/most-active/stocks"
page = requests.get(url, headers=headers)
html = page.text
soup = bs(html, 'html.parser')
print(soup.find_all())

import requests
from urllib.parse import unquote
import pandas as pd

headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:90.0) Gecko/20100101 Firefox/90.0",
}


def main(url):
    with requests.Session() as req:
        req.headers.update(headers)
        r = req.get(url[:25])
        req.headers.update(
            {'X-XSRF-TOKEN': unquote(r.cookies.get_dict()['XSRF-TOKEN'])})
        params = {
            "list": "options.mostActive.us",
            "fields": "symbol,symbolType,symbolName,hasOptions,lastPrice,priceChange,percentChange,optionsImpliedVolatilityRank1y,optionsTotalVolume,optionsPutVolumePercent,optionsCallVolumePercent,optionsPutCallVolumeRatio,tradeTime,symbolCode",
            "orderBy": "optionsTotalVolume",
            "orderDir": "desc",
            "between(lastPrice,.10,)": "",
            "between(tradeTime,2021-08-03,2021-08-04)": "",
            "meta": "field.shortName,field.type,field.description",
            "hasOptions": "true",
            "page": "1",
            "limit": "500",
            "raw": "1"
        }
        r = req.get(url, params=params).json()
        df = pd.DataFrame(r['data']).iloc[:, :-1]
        print(df)


main('https://www.barchart.com/proxies/core-api/v1/quotes/get?')

输出：
