我正在尝试从BBC美食网站上提取信息，但是在缩小我正在收集的数据方面遇到了一些麻烦。
这是我到目前为止的内容：
from bs4 import BeautifulSoup
import requests
webpage = requests.get('http://www.bbcgoodfood.com/search/recipes?query=tomato')
soup = BeautifulSoup(webpage.content)
links = soup.find_all("a")
for anchor in links:
print(anchor.get('href')), anchor.text
这将返回所涉及页面的所有链接以及该链接的文本描述，但是我想从页面上的“文章”类型对象中提取链接。这些是特定配方的链接。
通过一些实验，我设法从文章中返回了文本，但是我似乎无法提取链接。
我看到的与文章标签相关的仅有两件事是href和img.src：
from bs4 import BeautifulSoup
import requests
webpage = requests.get('http://www.bbcgoodfood.com/search/recipes?query=tomato')
soup = BeautifulSoup(webpage.content)
links = soup.find_all("article")
for ele in links:
print(ele.a["href"])
print(ele.img["src"])
链接在 "class=node-title"
from bs4 import BeautifulSoup
import requests
webpage = requests.get('http://www.bbcgoodfood.com/search/recipes?query=tomato')
soup = BeautifulSoup(webpage.content)
links = soup.find("div",{"class":"main row grid-padding"}).find_all("h2",{"class":"node-title"})
for l in links:
print(l.a["href"])

要访问，您需要先添加http://www.bbcgoodfood.com：
for l in links:
print(requests.get("http://www.bbcgoodfood.com{}".format(l.a["href"])).status
