python - Beautifulsoup 不会检索所有的 html

问题描述

我尝试抓取该游戏的玩家统计数据：“https://siege.gg/matches/5694-invitational-intl-faze-clan-vs-team-liquid”但看起来我的代码无法检索所有 html 可以有人帮我吗？

headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}

url="https://siege.gg/matches/5694-invitational-intl-faze-clan-vs-team-liquid"
match_page=requests.get(url, headers=headers)



match_soup = BeautifulSoup(match_page.content, features="lxml")

all_stats_soup=match_soup.find(id="DataTables_Table_0_wrapper")

解决方案

数据在 javascript 变量中。您可以使用re模块来解析它。

此示例将表格数据解析为pandaDataFrame：

import re
import requests
import pandas as pd
from io import StringIO

url = "https://siege.gg/matches/5694-invitational-intl-faze-clan-vs-team-liquid"

html_doc = requests.get(url).text
df = pd.read_html(StringIO(re.search(r"var a = `(.*)`", html_doc).group(1)))[0]

print(df)

或与bs4：

from bs4 import BeautifulSoup

soup = BeautifulSoup(
    re.search(r"var a = `(.*)`", html_doc).group(1), "html.parser"
)

for tr in soup.select("tr"):
    print(*tr.get_text(strip=True, separator="|").split("|"), sep="\t")
