从网页抓取时，html 与我检查元素时不一样？
When scraping from a webpage, the html isn't the same as when I inspect element?
我正在尝试通过网络抓取此网站：https://www.footballindex.co.uk/top-200
更具体地说，我想抓取每个玩家的名字、买入价、卖出价。
这是我用来获取网络的代码html:
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，我要查找的信息不会像在检查元素中那样出现在相关变量下。它出现在一长串代码中，如下所示。 （我已将其切断，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","name":"Bruno Fernandes",
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网站使用 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。但我完全不知道如何将信息提取到 python 中，以便我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，但每次它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？
我的解决方法——可能不是最好的——是使用 selenium 确保 javascript 加载所有数据，然后将此 HTML 传递给 beautifulsoup 进行解析并使用正则表达式匹配所需的数据。 time.sleep 用于确保 Java 中的所有数据都已加载。您可以试验它并根据需要降低它以加速您的脚本。
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主要 Div 页面。现在，您可以使用 REGEX 来查找您需要的一些数据。

我建议 https://pythex.org/ 您可以在其中测试您的正则表达式，而不必每次都 运行 编写脚本。
我正在尝试通过网络抓取此网站：https://www.footballindex.co.uk/top-200
更具体地说，我想抓取每个玩家的名字、买入价、卖出价。
这是我用来获取网络的代码html:
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，我要查找的信息不会像在检查元素中那样出现在相关变量下。它出现在一长串代码中，如下所示。 （我已将其切断，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","name":"Bruno Fernandes",
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网站使用 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。但我完全不知道如何将信息提取到 python 中，以便我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，但每次它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？
我的解决方法——可能不是最好的——是使用 selenium 确保 javascript 加载所有数据，然后将此 HTML 传递给 beautifulsoup 进行解析并使用正则表达式匹配所需的数据。 time.sleep 用于确保 Java 中的所有数据都已加载。您可以试验它并根据需要降低它以加速您的脚本。
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主要 Div 页面。现在，您可以使用 REGEX 来查找您需要的一些数据。
