Python Proxy IP Web Page Resolution Library: Python Proxy IP Resolution Tool

Have you ever stepped on these potholes? The Awkward Daily Life of Web Parsing

Do data crawl friends understand, obviously write the code, the results of the site suddenly give you aIP blocking. Last week, I was helping a client to capture the price of an e-commerce platform, and half an hour before, it was fine, and then suddenly it returned a 403 error. If you have a reliable proxy IP library at hand, you can just change the IP and continue to work.

Many newbies like to use free proxies, but 8 out of 10 don't work. Either the speed is as slow as a snail, or the line drops just after connecting. What's even worse is that some proxies willModify the response contentThe data captured is all garbled. At this time you need professional proxy service providers, such asipipgoThe stability of the exclusive IP pool is several notches higher than that of free proxies.

Build your own IP switching toolkit

Let's start by showing you a basic configuration template with the classic combination of requests library + proxy:

import requests
from bs4 import BeautifulSoup

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

response = requests.get('destination URL', proxies=proxies)
soup = BeautifulSoup(response.text, 'html.parser')
 Here's where you pick up your parsing logic

Note that you have to replace username withipipgoAuthentication information given in the background, their proxy channel supportvolumetric billingI'd like to use timeout=8, which is especially suitable for the scenarios that require flexible IP switching. When encountering a lot of CAPTCHA sites, it is recommended to set the timeout time shorter, I usually use timeout=8 is more secure.

Real-world examples: three great tricks to break through the countercrawl

Recently helped a friend to engage in recruitment website data collection, summarized a few practical tips:

Their API to get new IPs is especially fast, basically within 200ms you can get the available proxies.

A must-see guide to avoiding the pitfalls for beginners

Q: Why is it still blocked after using a proxy?

Q: What should I do if my proxy IP often times out?
A: It may be a network environment problem, tryipipgoThe different server room lines provided. The BGP line of their East China node is particularly stable, and the packet loss rate can be controlled below 1%.

Q: What if I need to use more than one agent at the same time?
A: Use the asynchronous request library aiohttp with proxy pool polling. Remember to use the asynchronous request library in theipipgoThe backend cranks up the concurrency count and their enterprise version supports 100+ IP switches per second.

Why do you recommend ipipgo?

Last time, there was a customer doing price monitoring, originally used a certain cheap agency services, the results of the key time to drop the chain. He switched toipipgoThe collection efficiency is directly doubled with the commercial version of the package. TheirIP purityIt does work and rarely gets flagged by the site.

A special shout-out to theirIntelligent Routingfunction, can automatically select the fastest node. Once I debugged the crawler at three o'clock in the morning, I was worried that the line is not stable at night, but the collection speed is actually faster than during the day. Now they send 5G traffic package for new users, fill in the coupon code when registering!PYTHON666You also get an extra 3-day trial.

One final word of advice: don't save money on proxy IPs, a good service provider can really save a lot of debugging time. Instead of tossing free proxies, useipipgoThis kind of professional services, problems and technical customer service support at any time, than their own online tutorials to find much more reliable.
