python - 如何从元素中提取链接？

Question

我正在尝试提取每个成员的链接，但没有得到输出:

from bs4 import BeautifulSoup
import requests

r = requests.get('https://www.asklaila.com/search/Delhi-NCR/-/doctors/')
soup = BeautifulSoup(r.text,'lxml')

for link in soup.find_all('h2',class_='resultTitle'):
    link1 = link.find('a')
    print link1['href']

Answer 1

您需要使用 header 参数请求 url。 more details

resultContent Delhi-NCR 的顶级医生结果 div 类，cardWrap 每个医生卡片 div 类。

from bs4 import BeautifulSoup
import requests

headers = {'User-Agent': 'Custom user agent'}
r = requests.get('https://www.asklaila.com/search/Delhi-NCR/-/doctors/',headers=headers)
soup = BeautifulSoup(r.text,'lxml')
resultContentArray = soup.find('div',{'class':'resultContent'}).find_all("div",{'class':'cardWrap'})

for rr in resultContentArray:
    title = rr.find('h2',{'class':'resultTitle'})
    link = rr.find("a",href=True)
    if link is not None:
        print(link['href'])
