Question

我刚开始学习bs4。我卡在下面的简单代码中，但没有得到任何输出。

我尝试使用没有运气的类来定位元素

from bs4 import BeautifulSoup
import requests

# url = "https://www.tutorialspoint.com/python3/index.htm"
url = "https://www.trivago.in/?aDateRange%5Barr%5D=2019-04-17&aDateRange%5Bdep%5D=2019-04-18&aPriceRange%5Bfrom%5D=0&aPriceRange%5Bto%5D=0&iRoomType=7&aRooms%5B0%5D%5Badults%5D=2&cpt2=64991%2F200&iViewType=0&bIsSeoPage=0&sortingId=1&slideoutsPageItemId=&iGeoDistanceLimit=20000&address=&addressGeoCode=&offset=0"
page = requests.get(url=url)

soup = BeautifulSoup(page.text,'lxml')
for s in soup.find_all("div"):
    print(s.get_text)

您可以访问json格式的响应：

import requests

url = 'https://hsg-prod-eu.nsp.trv.cloud/api/mvp/regionsearch/cep-p.json'

headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.86 Safari/537.36',

'acclim': '25'}


jsonData = requests.get(url, headers=headers, params=params).json()

accommodations = jsonData['accommodations']

for each in accommodations:

    name = each['name']['value']
    site = each['deals']['bestPrice']['name']['value']
    best_price = each['deals']['bestPrice']['displayPrice']

    print ('Hotel: %s\tSite: %s  Price: %s' %(name, site, best_price))
