Python Proxy IP Capture Tutorial: Getting Started with Python Proxy Capture

What exactly is the use of proxy IP? After reading this you will understand

Surfing the Internet always encounter IP blocked, right? For example, crawling data is blocked by the website, batch registration account is restricted, this time we need proxy IP to help us!Continue the operation under a different identity.The first thing that you need to do is to get your hands dirty. As if playing the game to open a small number, the main number is blocked can also use a small number then play.

The market is full of proxy service providers, here we must be favorable to us!ipipgoThe service of the family. It has a particularly useful function - dynamic residential IP, like a computer wearing a cloak of invisibility, each operation can automatically switch between different regions of the real user IP, will not be detected by the site.

Hands-on with Python to catch proxy IPs

Prepare a tool kit while you're at it first:

import requests
from bs4 import BeautifulSoup
import random

To give a practical example, we want to capture a site publicly available free proxy (note: the quality of free IP varies, we will teach you a more reliable method later):

def get_free_proxies():
    url = 'https://example-proxy-list.com' example site
    headers = {'User-Agent': random.choice(user_agents)}
    response = requests.get(url, headers=headers)
    soup = BeautifulSoup(response.text, 'html.parser')

    proxies = []
    for row in soup.select('table tr'):
        cells = row.find_all('td')
        if len(cells) >=2.
            ip = cells[0].text.strip()
            port = cells[1].text.strip()
            proxies.append(f"{ip}:{port}")
    return proxies

Caution! There are three major potholes in free IP:
1. Short survival time (may expire in half an hour)
2. Snail-speed Internet access
3. Easy to be blackmailed by the target website

The stable solution that the pros are using

Instead of tossing free IPs, just useAPI interface for ipipgoAnd three steps to get it done:

import requests

def get_ipipgo_proxy():
    api_url = "https://api.ipipgo.com/getproxy" official website to get real interface
    params = {
        'key': 'your api key',
        'protocol': 'socks5',
        'count': 10
    }
    response = requests.get(api_url, params=params)
    return response.json()['data']

Practical skills are open to the public

Share a few lessons learned from stepping in the pits:
1. Randomly switch the User-Agent before each request, don't let the website recognize you.
2. Critical operational useDedicated Static IP(e.g., registering for an account)
3. Don't fight with CAPTCHA, changing IP is less troublesome than cracking.

Tips for testing whether a proxy is working:

def test_proxy(proxy)::
    try.
        resp = requests.get('http://httpbin.org/ip',
            proxies={'http': proxy, 'https': proxy}, timeout=5))
            timeout=5)
        return True if resp.status_code == 200 else False
    return False if resp.status_code == 200 else False
        return False
