标题: 微信朋友圈刷票器 - 如何获得新的cookie PHPSESSID
本帖最后由 tanshipa 于 2018-1-2 18:00 编辑

我在做一个微信朋友圈的投票器，是第三方厂商做的投票 https://cx.cms01.com ，

限制了每人每IP地址每天只能投一票，我想用爬虫突破这一限制，达到刷票的目的。

我引入了代理ip池，可以做到每次以一个新的代理ip地址发起访问，但是服务器是通过对cookie PHPSESSID来判断是不是同一个客户端，即便用不同的ip地址发起访问，还是不能绕过服务器限制。

想问怎么样才能每次获得一个新的PHPSESSID？

我觉得把代码提上应该更直观，这是完整的代码，老师们可以直接运行看结果...

import requests

def get_ip_list(url, headers):
web_data = requests.get(url, headers=headers)
soup = BeautifulSoup(web_data.text, 'lxml')
ips = soup.find_all('tr')
ip_list = []
for i in range(1, len(ips)):
      ip_info = ips
      tds = ip_info.find_all('td')
      ip_list.append(tds[1].text + ':' + tds[2].text)
return ip_list

def get_random_ip(ip_list):
proxy_list = []
for ip in ip_list:
      proxy_list.append('http://' + ip)
proxy_ip = random.choice(proxy_list)
proxies = {'http': proxy_ip}
return proxies
