python - 如何检索雅虎搜索结果？

问题描述

我正在尝试使用以下代码在 Yahoo 上搜索查询：

import requests
from bs4 import BeautifulSoup

query = "deep"
yahoo = "https://search.yahoo.com/search?q=" + query + "&n=" + str(10)
raw_page = requests.get(yahoo)

soup = BeautifulSoup(raw_page.text)

for link in soup.find_all(attrs={"class": "ac-algo fz-l ac-21th lh-24"}):
    print (link.text, link.get('href'))

但这不起作用，结果是空的。如何获得 10 个第一搜索结果？

解决方案

您可以使用 Css Selector 来查找所有必须更快的链接。

import requests
from bs4 import BeautifulSoup

query = "deep"
yahoo = "https://search.yahoo.com/search?q=" + query + "&n=" + str(10)
raw_page = requests.get(yahoo)

soup = BeautifulSoup(raw_page.text,'lxml')

for link in soup.select(".ac-algo.fz-l.ac-21th.lh-24"):
    print (link.text, link['href'])

输出 ：
