查看抓取表单tripadvisor

Question

我是 python3 网络抓取的新手。我想抓取迪拜所有酒店的评论，但问题是我只能抓取我在网址中描述的酒店评论。谁能告诉我如何在不隐式提供每家酒店的网址的情况下获得所有酒店评论？

import requests
from bs4 import BeautifulSoup


importurl = 'https://www.tripadvisor.com/Hotel_Review-g295424-d302778-Reviews-Roda_Al_Bustan_Dubai_Airport-Dubai_Emirate_of_Dubai.html'
r = requests.get(importurl)
soup = BeautifulSoup(r.content, "lxml")
 resultsoup = soup.find_all("p", {"class" : "partial_entry"})
#save the reviews to a test text file locally
for review in resultsoup:
review_list = review.get_text()
print(review_list)
with open('testreview.txt', 'w') as fid: 
    for review in resultsoup:
        review_list = review.get_text()
        fid.write(review_list)

Answer 1

你应该找到所有酒店的索引页面，把所有的链接放到一个列表中，然后循环url列表来获取评论。

import bs4, requests
index_pages = ('http://www.tripadvisor.cn/Hotels-g295424-oa{}-Dubai_Emirate_of_Dubai-Hotels.html#ACCOM_OVERVIEW'.format(i) for i in range(0, 540, 30))
urls = []
with requests.session() as s:
    for index in index_pages:
        r = s.get(index)
        soup = bs4.BeautifulSoup(r.text, 'lxml')
        url_list = [i.get('href') for i in soup.select('.property_title')]
        urls.append(url_list)

出来：

len(urls): 540
