如何在 Selenium + Python 中查找损坏的链接

Question

我正在尝试在 Selenium 和 Python 中查找损坏的链接，但在代码中出现错误：

import requests
from selenium import webdriver

chrome_driver_path = "D:\\drivers\\chromedriver.exe"

driver=webdriver.Chrome(chrome_driver_path)

driver.get('https://google.co.in/')
links = driver.find_elements_by_css_selector("a")
images = driver.find_elements_by_css_selector("img")
for link in links:
    r = requests.head(link.get_attribute('href')
    print(r.status_code == 200)

无法在页面上找到损坏的链接是否有其他解决方案？

获取：

raise MaxRetryError(_pool, url, error or ResponseError(cause)) urllib3.exceptions.MaxRetryError： HTTPSConnectionPool（主机='myaccount.google.com'，端口=443）：最大 url 超出重试次数：/?utm_source=OGB&utm_medium=app（由 SSLError(SSLEOFError(8, 'EOF 发生违反协议 (_ssl.c:777)'),))

在处理上述异常的过程中，又发生了一个异常：

self._sslobj.do_handshake() ssl.SSLEOFError: EOF 发生违规 协议 (_ssl.c:777)

在处理上述异常的过程中，又发生了一个异常：

Traceback（最近一次调用最后一次）：

Answer 1

因为你在下一行缺少右括号还是错字？

r = requests.head(link.get_attribute('href'))

Answer 2

要查找页面上链接的状态，您可以使用以下解决方案：

• 代码块：

  import requests
  from selenium import webdriver
  
  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  options.add_argument('disable-infobars')
  driver=webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
  driver.get('https://google.co.in/')
  links = driver.find_elements_by_css_selector("a")
  for link in links:
      r = requests.head(link.get_attribute('href'))
      print(link.get_attribute('href'), r.status_code)

from selenium import webdriver
chrome_driver_path = "D:\\drivers\\chromedriver.exe"
driver=webdriver.Chrome(chrome_driver_path)
import requests
for link in links:
    r = requests.head(link)
    if r.status_code!=404:
         driver.get(link)
    else:
          print(str(link) + " isn't available.")
