如何在Selenium + Python中找到损坏的链接

标签: python-3.x selenium selenium-webdriver

我试图在Selenium和Python中找到一个损坏的链接,但在代码中出错:

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?

获得:

  

引发MaxRetryError(_pool,url,error或ResponseError(cause))   urllib3.exceptions.MaxRetryError:   HTTPSConnectionPool(host ='myaccount.google.com',port = 443):最多   使用url超出重试次数:/?utm_source = OGB& utm_medium = app(由   SSLError(SSLEOFError(8,'EOF违反协议发生)   (_ssl.c:777)'),))

在处理上述异常期间,发生了另一个异常:

  

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

在处理上述异常期间,发生了另一个异常:

因为您在下面的行中缺少右括号或是错字吗?

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

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)
