Data collection agent resources: massive IP anti-blocking crawling! Practical program

Teach you how to use proxy IP to do data collection.

What is the biggest headache in data collection? Of course, the IP is blocked! Yesterday, the script can be used today, a sudden break, the amount of data captured a little larger on the trigger anti-climbing, this thing who happened to have to curse the street. Don't panic, today I'll teach you a few wild ways to use proxy IP to arrange data collection in a clear way.

Why use a proxy IP, for example?

You take your own IP to climb a certain treasure commodity price, the first 10 pages well, climb to the 50th page directly to you block IP. this time if you canAutomatic switching of IP addresses for different regionsThe system thinks it is a different person browsing, and the probability of sealing the number is directly cut in half. It's like playing a game and opening a small number, sealing one and thousands of others.

 Python example: Extracting proxy IPs with ipipgo APIs
import requests

def get_proxy():
    api_url = "https://api.ipipgo.com/getip?type=dynamic&count=10"
    resp = requests.get(api_url).json()
    return [f"{ip}:{port}" for ip, port in resp['data']]

 Once you have the IP pool, use random requests or scrapy to match it up with a setting
proxies = {
    
    'https': 'http://12.34.56.78:8080'
}
response = requests.get('target site', proxies=proxies)

How to choose a proxy IP without stepping into a pit?

There are three types of agents on the market, to paint a picture for you:

Focusing on dynamic residential IPs, this thing automatically refreshes the IP pool every hour, especially suitable for those who need toCollect tens of thousands of pages per dayThe business. Previously there is a do price comparison website buddy, with static IP three days two to three times was blocked, after changing to dynamic IP collection success rate from 40% soared to 92%.

Practical anti-blocking three axes

1. IP rotation strategy should be flirty enoughDon't be silly and use the IPs in order, it is recommended to randomly disrupt the order of use. ipipgo's API supports setting the extraction interval, it is recommended to change the IPs every 5-10 requests.

2. Don't be lazy about requesting header camouflage: Remember to randomly switch User-Agent in the code, Windows/Mac/iOS/Android device types all the time, don't let the site see that you're a machine!

3. Capture rhythms like real people: add randomized wait times, less collection in the middle of the night, differentiate between weekday and weekend visits, mimic real people's routine
