从网页抓取时，html 与我检查元素时不同？答案

【问题标题】：When scraping from a webpage, the html isn't the same as when I inspect element?从网页抓取时，html 与我检查元素时不同？

【问题描述】：

我正在尝试抓取这个网站：https://www.footballindex.co.uk/top-200

更具体地说，我想获取每个玩家的姓名、买入价、卖出价。

这是我用来获取网页 html 的代码：

import requests
from bs4 import BeautifulSoup

URL = "https://www.footballindex.co.uk/top-200"
page = requests.get(URL)
Soup = BeautifulSoup(page.text, "html.parser")
print(Soup)

当我打印出 html 时，我正在寻找的信息不会像检查元素那样出现在相关变量下。它以一长行代码形式出现，如下所示。（我已将其关闭，但它会为页面上的每个玩家执行此操作）。

window.__PRELOADED_STATE__ = {"tradingReducer":{"adjustedPrice":0,"isLoading":false},"playersReducer":{"players":[{"id":"phil-foden","name":"Phil Foden","rank":14,"country":"England","nationalTeam":null,"sector":"Midfielder","nationality":"England","team":"Manchester City","optimized_image ":"phil-foden-g-t4.jpg","buyPrice":5.93,"sellPrice":5.87,"penceChange":0.12,"changePercent":2.05},{"id":"bruno-fernandes", “名称”：“布鲁诺·费尔南德斯”，

我也尝试过使用 Selenium，但它只是在同一个地方给了我数据。从我读过的其他帖子和信息中，我发现这听起来像是因为该网站特别使用 Java 来加载玩家的价格。在页面上，它们每隔几秒就会不断更新。

代码似乎是 JSON 格式。但是我完全不知道如何将信息提取到 python 中，这样我就可以捕获每个玩家及其相关的购买价格。我试过使用 find 和 find_all 函数，但每次似乎都没有提取任何数据。

有谁知道我需要使用什么代码才能从 html 中正确提取我想要的变量？

【问题讨论】：

嗨，hammer96，欢迎堆栈溢出 ;-) 当您检查页面时，您会看到当前呈现的 DOM - 这意味着通过 JavaScript 等添加的所有动态 HTML 也在其中.如果只是下载页面源代码就不是这样了。

标签： java python beautifulsoup screen-scraping

【解决方案1】：

我的解决方法——可能不是最好的——是使用 selenium 来确保 javascript 加载所有数据，然后将此 HTML 传递给 beautifulsoup 以解析和使用正则表达式来匹配所需的数据。 time.sleep 用于确保加载 Java 中的所有数据。您可以试验它并根据需要降低它以加快您的脚本速度。


from selenium import webdriver
import time
from bs4 import BeautifulSoup 
import re

browser = webdriver.Firefox()
browser.set_window_size(700,900)

url = 'https://www.footballindex.co.uk/top-200'

browser.get(url)
time.sleep(4)

html = browser.execute_script('return document.documentElement.outerHTML')


all_html = BeautifulSoup(html,'lxml')
root = all_html.find('div', {'class':'List__container___1xBmN'})

all_buy_prices= re.findall('(buy" type="button">)(\£\d+\.\d+)(</button>)', str(root))

buy_price= all_buy_prices
print('Buy prices:')
print(str(buy_price))

browser.quit()

这将为您提供包含所有数据的页面的主 Div。现在，您可以使用 REGEX 来查找您需要的一些数据。
