在BeautifulSoup中解析网页时获取错误链接

from bs4 import BeautifulSoup
import requests

url = "待解析的网页链接"
response = requests.get(url)
html_content = response.text

soup = BeautifulSoup(html_content, 'html.parser')

for link in soup.find_all('a'):
    href = link.get('href')
    # 进行链接有效性检查
    if href.startswith('http'):
        try:
            response = requests.head(href)
            if response.status_code != 200:
                print("错误链接：", href)
        except requests.exceptions.RequestException as e:
            print("错误链接：", href)
