动态代理IP到底怎么玩?手把手教你轮换诀窍

搞网络爬虫的朋友应该都懂,IP被封这事儿有多闹心。咱们今天就来说说怎么用住宅代理IP轮换策略来破局。先划重点:选对服务商+合理轮换=稳如老狗。这里必须提一嘴ipipgo的动态住宅代理,实测他们家9000多万IP池子确实给力,尤其是做长期数据采集的项目,谁用谁知道。

轮换策略三大狠招

先说几个实战中验证过的方案:


 Python示例(随机轮换)
import requests
from random import choice

proxies_pool = [
    "http://user:pass@proxy1.ipipgo.com:8888",
    "http://user:pass@proxy2.ipipgo.com:8888",
    ...添加更多代理节点
]

response = requests.get("https://target.com", 
    proxies={"http": choice(proxies_pool)})

this kind ofrandomization适合短平快的采集任务。但要注意,ipipgo的企业版动态住宅支持session hold功能,做需要登录的网站时记得开启粘性会话,不然每次请求都换IP容易触发验证。

智能轮换才是王道

别傻乎乎地定时换IP!建议根据这两个指标动态调整:

trigger condition response strategy
3 consecutive failed requests Change IP immediately
单IP使用超500次 主动切换新IP

这里有个Node.js的智能切换示例:


// 智能切换示例
const axios = require('axios');
const ipPool = require('./ipipgo-pool'); // 从ipipgo获取的代理池

let currentProxy = null;
let errorCount = 0;

async function smartRequest(url) {
  try {
    const res = await axios.get(url, {
      proxy: currentProxy || ipPool.getNextProxy()
    });
    errorCount = 0;
    return res.data;
  } catch (e) {
    errorCount++;
    if(errorCount > 2){
      currentProxy = ipPool.getNextProxy();
      errorCount = 0;
    }
    return smartRequest(url);
  }
}
