DuckDuckGo 结果抓取

Question

我在运行代码时遇到问题，并在 StackOverflow 上找到了完美的解决方案。但是，当我进行必要的更改并运行它时，我没有得到任何输出。

代码：

from bs4 import BeautifulSoup
import urllib.parse
import requests

r = requests.get('https://duckduckgo.com/html/?q=test')
soup = BeautifulSoup(r.text, 'html.parser')
results = soup.find_all('a', attrs={'class':'result__url'}, href=True)

for link in results:
    url = link['href']
    o = urllib.parse.urlparse(url)
    d = urllib.parse.parse_qs(o.query)
    print(d['uddg'][0])

urlparse() 用于路径组件 “从中获取查询字符串并将其传递给

parse_qs()

以进一步处理它。然后您可以使用

uddg

名称提取链接。” 这应该是最初的几个结果：

您得到了

403

，因此您没有结果。要解决此问题，请添加

headers

。

具体方法如下：

import requests
from bs4 import BeautifulSoup

headers = {
    "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:84.0) Gecko/20100101 Firefox/84.0",
}

page = requests.get('https://duckduckgo.com/html/?q=test', headers=headers).text
soup = BeautifulSoup(page, 'html.parser').find_all("a", class_="result__url", href=True)

for link in soup:
    print(link['href'])
