How to Crawl Websites with Python: Proxy IP Bypass Limits Tutorial

Hands-on with wild ways to prevent IP blocking when crawling data with Python

Brothers engaged in crawling understand that the most feared is not the data is difficult to catch, but the site to you to play the IP blocking of the tawdry operation. Today, we will give the guys a tough trick - use proxy IP to play with the Golden Cicada Shell. Let's take our ownipipgoservice as an example to show you how to juggle proxy IPs in Python.

What's the deal with proxy IPs anyway?

In a nutshell.Borrowing someone else's vest to surf the netThe first thing you need to do is to use your own IP to brush up on a website. For example, if you want to climb a certain website and use your own IP to swipe, they will pull the plug on you in minutes. But if you change the IP address every time you request, the website will be confused, and you won't be able to tell whether it's the Li Kui or the Li Ghost.

 For example, using the requests library to hook up a proxy
import requests

proxies = {
    'http': 'http://username:password@gateway.ipipgo.com:9020',
    'https': 'http://username:password@gateway.ipipgo.com:9020'
}

response = requests.get('destination URL', proxies=proxies, timeout=10)

Proxy IP configuration in four steps

1. Go firstipipgo official websiteGet a package. We recommend Dynamic Residential Agents. It's a great way to stay hidden.
2. get the API interface address and account password (pay attention to the port number in the document)
3. Setting up the proxy dictionary in the code as above
4. Here comes the kicker! Remember to addException Retry MechanismIf an IP hangs, you'll immediately switch to the next one.

The easy way to fall on your face in the real world

Old driver's private code snippet

from itertools import cycle
import requests

 IP pool from ipipgo
ip_list = [
    'gateway.ipipgo.com:9020',
    'gateway.ipipgo.com:9021',
    'gateway.ipipgo.com:9022'
]
proxy_pool = cycle(ip_list)

for _ in range(10).
    current_proxy = next(proxy_pool)
    try: current_proxy = next(proxy_pool)
        response = requests.get(
            url='target url',
            proxies={'http': f'http://账号:密码@{current_proxy}'},
            headers={'User-Agent': 'Mozilla/5.0'},
            timeout=8
        )
        print('Successfully fetching data')
        break
    except.
        print(f'{current_proxy} flipped, move to the next one!)

Frequently Asked Questions QA

Q: Can't I just use a free proxy? Why do I need to buy ipipgo?
A: Nine out of ten free agents are pits! Either the speed is slow into a turtle, or with two hang. ipipgo IP pool updated every day 200,000 + IP, the success rate of 95% guaranteed!

Q: How can I tell if a proxy IP is truly anonymous?
A: Visit httpbin.org/ip to see if the returned IP is a proxy IP or not. if you use ipipgo's high stash service, you can't detect the real IP at all!

Q: What should I do if I encounter a CAPTCHA?
A: ipipgo's intelligent routing can automatically avoid high-risk IP, coupled with the coding platform, a two-pronged approach

Lastly, using a proxy IP is not a cure-all.Request frequency control+stochastic delay+request header masquerading as..
