Web crawling tool: proxy IP rotation integration to avoid anti-crawling program

What veteran reptile drivers know

Recently, a lot of friends to do data crawling with me, said that now the site anti-climbing mechanism is more and more ruthless. Not moving on the IP, hard to write the script can not run for two minutes on the break. This thing, like a gopher - you change a position to visit, they immediately change a position to block you.

Last week there is an e-commerce price comparison of buddies even more desperate, their team to use their own office network to capture data, as a result, the entire company IP segments have been blackened, and even normal access to the site has become a problem. I'll tell you what.Proxy IP RotationIt's a must-have move, in the same way that playing a game of chicken with stealth mode on is a good idea.

Proxy IP in the end how to choose reliable

There are all sorts of agent types on the market, just like instant noodles in the supermarket. Here to draw a focus for you:

Take ipipgo for example, their dynamic residential IP pool is updated with millions of IP resources every day, which is especially suitable for scenarios that require frequent switching. I've tested it before, and using their API to extract IPs, you can get a freshly baked proxy address in 5 seconds.

import requests
from random import choice

def get_ipipgo_proxy(): api_url =
    api_url = "https://api.ipipgo.com/getproxy"
    params = {
        "key": "Your API key",
        "protocol": "socks5",
        "count": 10
    }
    response = requests.get(api_url, params=params).json()
    return [f"{p['protocol']}://{p['ip']}:{p['port']}" for p in response['data']]

proxies_pool = get_ipipgo_proxy()

 Randomize the proxy and set the request headers
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64)'}
session = requests.Session()
session.proxies = {'http': choice(proxies_pool), 'https': choice(proxies_pool)}
response = session.get('destination URL', headers=headers)

A guide to avoiding pitfalls in real-world configurations

Here are a few easy places to plant your head:

1. Switching frequencyDon't be too regular, it's better to set random intervals
2. Remember to assign different User-Agents to different agents.
3. check whether the proxy is available before each request (don't wait until you are blocked to realize)

A client doing public opinion monitoring told me that they use the client tool of ipipgo to directly set up the intelligent switching mode, and the system will automatically eliminate the invalid IPs, which is comparable to autopilot.

Frequently Asked Questions

Q: What should I do if my agent is slow?
A: Priority to choose geographically proximate nodes, ipipgo support for filtering IP by country/city, don't be silly to use South American IP to catch the domestic site!

Q: What if there are always a few IPs recognized?
A: We recommend upgrading to the Enterprise package. ipipgo's Dynamic Residential (Enterprise) package comes with advanced camouflage features!

Q: What if I need a lot of fixed IPs?
A: Directly on the static residential package, 35 dollars / IP / month, much cheaper than hiring a programmer

Say something from the heart.

In fact, nowadays, when you do data collection, the quality of resources is spelled out. After using five or six service providers, I found that ipipgo'sTK LineIt's really something. That client tool of theirs can also look at the survival time of the IP, just like the takeout software shows the location of the rider, it's very intuitive.

A final reminder for newbies:Don't use free proxies for cheapThat thing is like a toilet seat in a public restroom...it looks like it works, but when you really have to sit down...you get the picture. Spend a little money to buy professional services, save the cost of time are enough to eat ten hot pot.
