Python测试代理ip是否有效

方式一: 通过icanhazip.com返回的ip地址进行检测

import requests
'''代理IP地址(高匿)'''
proxy = {
'http': 'http://117.85.105.170:808',
'https': 'https://117.85.105.170:808'
}
'''head 信息'''
head = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36',
'Connection': 'keep-alive'}
'''http://icanhazip.com会返回当前的IP地址'''
p = requests.get('http://icanhazip.com', headers=head, proxies=proxy)
print(p.text)

方式二: Telnet方法

import telnetlib

def test_ip(ip,port):
try:
telnetlib.Telnet(ip,port,timeout=2)
print("代理ip有效!")
except:
print("代理ip无效!") test_ip("221.6.139.158","9000")
