python - 无法使用 Selenium Python 以表格形式获取数据

问题描述

我是使用 selenium python抓取的新手。所以我可以检索一些数据，但我希望它以表格形式显示在网页上：

这是我到目前为止所拥有的：

url='https://definitivehc.maps.arcgis.com/home/item.html?id=1044bb19da8d4dbfb6a96eb1b4ebf629&view=list&showFilters=false#data'

browser = webdriver.Chrome(r"C:\task\chromedriver")
browser.get(url)
time.sleep(25)


rows_in_table = browser.find_elements_by_xpath('//table[@class="dgrid-row-table"]//tr[th or td]')
for element in rows_in_table:
    print(element.text.replace('\n', ''))

结果片段：

我将非常感谢专家对此的帮助。谢谢。

解决方案

数据是使用 Javascript 动态加载的。您可以使用requests模块来模拟这些请求：

import json
import requests

config_url = 'https://definitivehc.maps.arcgis.com/sharing/rest/portals/self?culture=en-us&f=json'
page_url = 'https://services7.arcgis.com/{_id}/arcgis/rest/services/Definitive_Healthcare_USA_Hospital_Beds/FeatureServer/0/query?f=json&where=1%3D1&returnGeometry=false&spatialRel=esriSpatialRelIntersects&outFields=*&orderByFields=OBJECTID%20ASC&resultOffset={offset}&resultRecordCount=50&cacheHint=true&quantizationParameters=%7B%22mode%22%3A%22edit%22%7D'

_id = requests.get(config_url).json()['id']

offset = 0
while True:
    data = requests.get(page_url.format(_id=_id, offset=offset)).json()

    # uncommnet this to print all data:
    # print(json.dumps(data, indent=4))

    for i, f in enumerate(data['features'], offset+1):
        print(i, f['attributes'])
        print('-' * 160)

    if i % 50:
        break

    offset += 50
