当爬虫遇上反爬,试试这招最管用

搞数据采集的朋友都懂,最头疼的就是网站封IP。昨天还跑得好好的脚本,今天突然就卡住不动了。这时候千万别慌,给爬虫套个隐身马甲——也就是代理IP,问题迎刃而解。

选对代理类型,效率翻倍涨

市面上的代理IP分好几种,用错了就像穿错衣服去参加派对。给大伙列个对比表:

typology Applicable Scenarios price range
Dynamic Residential Routine data collection From $7.67/GB
Static homes Services requiring fixed IP From $35/IP
TK Line Special Business Requirements Customized Quotation

比如要采集电商价格,用动态住宅IP每小时自动更换,既不容易被发现,成本也划算。要是做账号注册这类需要固定IP的操作,就得选静态住宅。

Hands-on agent matching

这里用Python的requests库举个栗子,三步就能搞定:


import requests

 从ipipgo获取的代理地址
proxy = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:端口',
    'https': 'http://用户名:密码@gateway.ipipgo.com:端口'
}

resp = requests.get('目标网址', proxies=proxy, timeout=10)
print(resp.text)

注意把用户名密码换成自己在ipipgo后台生成的认证信息,建议用whitelisting更安全。要是用Scrapy框架,在settings.py里加上这几行:


DOWNLOADER_MIDDLEWARES = {
    'scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware': 400,
}

A guide to avoiding the pitfalls (a must-see for beginners)

A few common mistakes made by newbies:

  1. 代理池太小——至少准备50个IP轮流用
  2. 没设置超时——建议5-10秒,超时就换IP
  3. 忘记随机间隔——在请求之间加0.5-3秒随机等待

要是遇到验证码轰炸,可以试试ipipgo的TK line agent,专门针对有严格验证的网站设计的解决方案。

QA时间(收藏备用)

Q: What should I do if my proxy IP is slow?
A:优先选择本地运营商资源,比如采集国内网站就选大陆节点。ipipgo的代理后台能实时看到节点延迟。

Q: How can I tell if my IP is blocked?
A:两个征兆——突然大量请求失败,或者返回403状态码。建议设置自动检测机制,发现异常自动切换IP。

Q: How do I choose a package for Enterprise Capture?
A:数据量超10万条/天的话,直接上动态住宅(企业版),9.47元/GB支持多线程并发,还带专属客服。

  • 200多个国家的本地IP,采集海外数据时特方便
  • 支持socks5协议,某些特殊场景下比http更稳定

最后提醒大伙,用代理IP也要遵守网站规则,别把人家服务器搞崩了。合理设置请求频率,咱们既要数据,也要做个有底线的技术人。
