【问题标题】：Python BeautifulSoup problem with extractPython BeautifulSoup 提取问题
【发布时间】：2020-05-08 01:13:02
【问题描述】：
我想提取一些数据并放在excel中。
我的问题在于提取，我没有获取比元素检查看到的所有信息。通过元素检查，我可以看到每个元素、品牌、公里、价格等......所有这些信息都在我的摘录中，但在脚本中，而不像我在网站上看到的那样。

import requests
from bs4 import BeautifulSoup
URL = 'https://www.alcopa-auction.fr/salle-de-vente-encheres/nancy/2110'
page = requests.get(URL)
headers = {"User-Agent": 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_2) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.0.4 Safari/605.1.15'}
page = requests.get(URL, headers=headers)
soup = BeautifulSoup(page.content, 'html.parser')
print(soup)

【解决方案1】：
您在页面上看到的数据以 JSON 格式嵌入到页面中。例如，您可以像这样提取它：
import re
import json
import requests
url = 'https://www.alcopa-auction.fr/salle-de-vente-encheres/nancy/2110'
txt = requests.get(url).text
json_string = re.search(r'window.Alcopa.searchResultsJSONString = \'(.*)\';', txt)[1]
data = json.loads( json.loads('"{}"'.format(json_string)) )
# print(json.dumps(data, indent=4)) # <-- uncomment this to see all data
print('{:<20} {:<70} {:<10} {:<10} {:<10}'.format('Brand', 'Model', 'Price', 'Sale Date', 'Sale End Date'))
for car in data['car']:
print('{:<20} {:<70} {:<10} {:<10} {:<10}'.format(car['brand'], car['detailed_model'], car['price'], car['sale_date'], car['sale_end_date']))
