本篇文章小编给大家分享一下Python快速验证代理IP是否有效代码实现方法,文章代码介绍的很详细,小编觉得挺不错的,现在分享给大家供大家参考,有需要的小伙伴们可以来看看。
有时候,我们需要用到代理IP,比如在爬虫的时候,但是得到了IP之后,可能不知道怎么验证这些IP是不是有效的,这时候我们可以使用Python携带该IP来模拟访问某一个网站,如果多次未成功访问,则说明这个代理是无效的。
代码如下:
import requests import random import time http_ip = [ '118.163.13.200:8080', '222.223.182.66:8000', '51.158.186.242:8811', '171.37.79.129:9797', '139.255.123.194:4550' ] for i in range(10): try: ip_proxy = random.choice(http_ip) proxy_ip = { 'http': ip_proxy, 'https': ip_proxy, } print('使用代理的IP:', proxy_ip) response = requests.get("http://httpbin.org/ip", proxies=proxy_ip).text print(response) print('当前IP有效') time.sleep(2) except Exception as e: print(e.args[0]) print('当前IP无效') continue
运行结果如下:
使用代理的IP: {'http': '118.163.13.200:8080', 'https': '118.163.13.200:8080'}
HTTPConnectionPool(host='118.163.13.200', port=8080): Max retries exceeded with url:http://httpbin.org/ip(Caused by ProxyError('Cannot connect to proxy.', NewConnectionError('
