proxy's Introduction

爬取代理并存储

爬取 http://www.xicidaili.com/http://cn-proxy.com/ 代理并用 sqlite3 存储,其中 cn-proxy 需翻墙。

用法

  • 安装依赖:pip install requests bs4

  • 更新脚本:python proxy.py

  • 从数据库中获取代理,示例:

  import proxy # proxy.py 在当前执行路径下
  
  requests.get('https://www.baidu.com/', proxies=proxy.get())

特色

  • 每次获取代理时,先检查代理是否可用,不可用则从数据库中删除,重新获取直至可用。
  • 更新代理时,不插入已存在的代理,不重复创建表。
  • 自动判断网络环境,若不能翻墙则只爬取西刺代理。
  • 用 Python 自带的 sqlite3 存储,简单,方便。
