python - 无法使用 Selenium 或 BeautifulSoup 抓取动态内容

问题描述

我正在尝试从 URL 中抓取动态内容：https://www.prokabaddi.com/stats/0-102-total-points-statistics。尝试过使用 selenium，BeautifulSoup 但都给我一个空列表。我的代码是：

url = "https://www.prokabaddi.com/stats/0-102-total-points-statistics"

# create a new Chrome session
driver = webdriver.Chrome()
driver.get(url) 
soup.find_all("div", class_="sipk-lb-playerName")

这将返回一个空列表。当我在控制台中检查数据时数据存在，但在页面源中数据和div标签不存在。我相信这与 js 渲染的内容有关。

如何从此 URL 中提取玩家名称和积分。

解决方案

进入开发工具并查看 XHR。您将看到直接提取数据的 url。它以 json 格式返回，但可以将其转换为表格：

代码：

import requests
from pandas.io.json import json_normalize

url = 'https://www.prokabaddi.com/sifeeds/kabaddi/static/json/1_0_102_stats.json'
jsonData = requests.get(url).json()

table = json_normalize(jsonData['data'])

输出：

print (table.head(5).to_string())
   match_played  player_id         player_name  position_id position_name rank team        team_full_name  team_id team_name  value
0           101        197      Pardeep Narwal          8.0        Raider    1  PAT         Patna Pirates        6       PAT   1055

3           115         26         Ajay Thakur          8.0        Raider    4   TT       Tamil Thalaivas       29        TT    811

并过滤以仅获取名称和积分：

print (table[['player_name','value']])
                     player_name  value
