一、为什么你的爬虫总被识别?先搞懂代理IP怎么用

很多兄弟在用requests库时,死活搞不明白代理IP到底该挂在Session上还是单次请求。说白了这就像你打游戏选装备——用对了事半功倍,用错了直接被秒。举个栗子,有些网站专门盯着IP访问频率,你要是每个请求都换IP,反而会触发风控。这时候就得根据业务场景,选对代理模式。

二、Session模式:VIP专属通道

Session对象就像你的私人管家,所有请求都走同一条通道。用ipipgo的Static Residential Agents时特别合适,比如需要保持登录状态或者处理验证码的场景。看这段代码:


import requests
proxies = {
    'http': 'http://user:pass@gateway.ipipgo.com:24000',
    'https': 'http://user:pass@gateway.ipipgo.com:24000'
}

with requests.Session() as s:
    s.proxies = proxies
     所有请求自动走代理
    s.get('https://目标网站')

Note the use ofstatic IP,适合需要长期稳定连接的场景。ipipgo的静态住宅代理自带运营商级稳定性,比那些动不动就掉线的野鸡代理强多了。

三、单请求模式:灵活游击战

需要频繁切换IP的时候,比如做数据采集,就得用动态代理。这时候每次请求都单独设置代理:


import requests

def get_proxy():
     这里调用ipipgo的动态代理API获取新IP
    return {'http': 'http://动态IP地址:端口'}

response = requests.get(
    'https://目标网站',
    proxies=get_proxy()
)

这种模式适合用ipipgo的Dynamic Residential Agents,他们的IP池有9000万+资源,根本不怕IP被封。不过要注意设置合理的请求间隔,太频繁了神仙也救不了。

四、模式对比怎么选?看这张表就够

comparison term Session模式 单请求模式
Applicable Scenarios Need to maintain session state Frequent IP changes required
Agent Type Static Residential Agents Dynamic Residential Agents
连接开销 低(复用连接) 高(每次新建)
IP switching frequency fixed IP 可自定义时长

V. Practical guide to avoiding pitfalls

最近有个做电商的朋友,用单请求模式死活采集不到数据。后来发现是代理池质量太差,换了ipipgo的Dynamic Residential Enterprise Package才解决。这里分享几个血泪经验:

  1. 认证问题:ipipgo的代理需要账号密码认证,千万别写成proxies={‘http’:’ip:port’}这种格式
  2. protocol matching
  3. timeout setting:建议搭配timeout参数使用,别让烂代理卡死你的程序

VI. Frequently Asked Questions QA

Q: Proxy settings are successful but I can't connect?
A:先检查IP端口是否正确,再用curl命令测试连通性。如果用的是ipipgo服务,他们的控制台有实时可用率监控。

Q: How do I set up a proxy for my HTTPS website?
A:很多人只配了http忘了https,正确的写法是:
proxies = {‘http’: ‘…’, ‘https’: ‘…’}

Q: What if I need to use more than one agent at the same time?
A: In this case it is recommended to go on ipipgo'sAgent Pool API,他们的动态住宅套餐支持每秒100+次IP切换。

七、选对服务商才是王道

最后唠叨一句,代理IP这玩意儿三分靠技术七分靠资源。像ipipgo这种有真实住宅IP的服务商,自带City-level positioningrespond in singingCarrier-grade dedicated lines,比那些用机房IP的靠谱多了。特别是他们的TikTok Solutions,做海外直播的老铁们可以重点关注,实测延迟能压到2ms以内。

They've recently put on a new按成功数计费的SERP API,做SEO监控的兄弟不用再自己折腾代理池了。记住,专业的事交给专业的人,省下来的时间多陪陪家人不香么?
