Web Crawler: Crawler Proxy IP Settings Guide

First, hand to teach you to the crawler installed "cloak" crawler know, the site anti-climbing mechanism with the security checkpoints like, caught high-frequency access to the IP on the black. At this time, the proxy IP is like to give the crawler to wear a cloak, so that each request to change a "face". For example, with ipi...

Web Crawler: Crawler Proxy IP Settings Guide

一、手把手教你给爬虫装”隐身衣”

搞爬虫的都知道,网站反爬机制就跟安检门似的,逮着高频访问的IP就拉黑。这时候代理IP就像给爬虫穿隐身衣,让每个请求都换张”脸”。举个栗子,用ipipgo的动态住宅代理,每次请求自动换IP,网站根本分不清是真人浏览还是机器操作。


import requests

 示例:Python爬虫设置代理
proxy = "http://用户名:密码@gateway.ipipgo.net:端口"
proxies = {
    "http": proxy,
    "https": proxy
}

response = requests.get("目标网址", proxies=proxies, timeout=10)

Note the use of用户名密码认证模式,别直接用IP白名单,容易被反爬系统识破。ipipgo的代理支持HTTP/HTTPS双协议,记得根据目标网站协议类型选对代理模式。

二、选代理IP就像挑水果要看新鲜度

市面代理分三大类(敲黑板):

Dynamic Residential Agents:适合高频抓取,IP存活时间短但量大管饱
Static Residential Agents:适合长期监控,IP存活30天起步
Data Center Agents:价格便宜但容易被识别

举个真实案例:有个做比价网站的哥们,用普通代理每天被封200+次,后来换成ipipgo的Dynamic Residential (Enterprise Edition),9块多1GB流量,配合IP轮换策略,封禁率直接降到5%以下。

三、三步搞定ipipgo代理配置

1. After registering on the official website, go to the console and selectAPI Extractionmaybedirect client connection
2. 动态代理建议设置5分钟更换周期
3. 代码里记得加异常重试机制


 自动重试示例
max_retries = 3
for _ in range(max_retries):
    try:
        response = requests.get(url, proxies=proxies)
        break
    except Exception as e:
        print(f"第{_+1}次重试,错误:{str(e)}")

四、新手必看的防坑指南

坑1:代理池太小
别贪便宜用免费代理,IP池就几百个的,分分钟被反爬教做人。ipipgo的全球200+国家资源池,动态代理单日可用IP超百万。

坑2:协议没配对
爬HTTPS网站用HTTP代理会报SSL错误,反过来也不行。建议代码里同时配置两种协议:


proxies = {
    "http": "http://代理地址",
    "https": "http://代理地址"   注意这里也要用http协议
}

V. First aid kits for common problems

Q: What should I do if the agent suddenly fails to connect?
A:先检查账号余额,再用ipipgo客户端自带的Connectivity testing功能。如果大面积失效,立即联系客服换IP段。

Q:爬虫速度变慢怎么办?
A:1. 切换为静态住宅代理 2. 调大并发数 3. 检查本地网络带宽。ipipgo的跨境专线延迟最低能压到80ms,比普通线路快3倍。

Q: How do I choose a package with a limited budget?
A:高频抓取选Dynamic Residential Standard(7.67元/GB),长期监控用Static homes(35元/IP),需要低延迟上TK专线。

六、资深程序员的私房技巧

1. 设置随机请求间隔:在0.5-3秒之间随机休眠
2. 混合使用代理类型:用80%动态+20%静态代理分摊风险
3. 伪装请求头:记得定期更新User-Agent和Cookie

One last piece of cold knowledge: with ipipgo'sSERP API直接获取搜索引擎结果,比自建爬虫省心得多。他们家的云服务器还能直接部署爬虫程序,数据不出内网,安全性拉满。
