BeautifulSoup和scraping的不起作用

Question

再一次，我在BeautifulSoup中刮href有困难。我有一个页面列表，我正在抓取，我有数据，但我似乎无法得到href，即使我使用各种代码，在其他脚本工作。

下面是代码，我的数据如下：

import requests
from bs4 import BeautifulSoup


with open('states_names.csv', 'r') as reader:
    states = [states.strip().replace(' ', '-') for states in reader]


url = 'https://www.hauntedplaces.org/state/alabama'

for state in states:
    page = requests.get(url+state)
    soup = BeautifulSoup(page.text, 'html.parser')
    links = soup.findAll('div', class_='description')
    # When I try to add .get('href') I get a traceback error. Am I trying to scrape the href too early? 
    h_page = soup.findAll('h3')

Answer 1

这是非常有效的：

from bs4 import BeautifulSoup
import requests

url = 'https://www.hauntedplaces.org/state/Alabama'

r = requests.get(url)
soup = BeautifulSoup(r.text, 'lxml')

for link in soup.select('div.description a'):
    print(link['href'])

Answer 2

试一试：

soup = BeautifulSoup(page.content, 'html.parser')
list0 = []   
possible_links = soup.find_all('a')
for link in possible_links:
    if link.has_attr('href'):
        print (link.attrs['href'])
        list0.append(link.attrs['href'])
print(list0)
