How to get free proxy IP: free IP source grabbing and verification

Where to skim free proxy IPs from? Try these wildcards

Engaged in network crawlers old iron people understand, free proxy IP is like street food, eat fragrant but easy to diarrhea. First of all, a few serious ways:

1. Open site pick data: some sites specializing in updating the free agent, such as a site called "fast agent", with Python to write a crawler script will be able to woolgathering. The code looks like this:

import requests
from bs4 import BeautifulSoup

url = 'https://www.kuaidaili.com/free/'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
ips = [tr.find_all('td')[0].text for tr in soup.select('list table tr')]

2. GitHub pick up leaks: search "free proxy list" can find a lot of warehouses, pay attention to the latest update time, more than half a year, do not touch!

3. Squatting in technical forums: places like V2EX are occasionally shared, but you have to take your chances, just like picking up cigarette butts.

Three things you must do when your free IP arrives

Don't rush it. Go through these three first:

Level 1: Life and death check - Use this script to measure connectivity. Anyone who can survive more than 10 seconds is a good man.

import requests

def test_proxy(ip, port).
    test_proxy(ip, port): test_proxy(ip, port).
        res = requests.get('http://httpbin.org/ip',
                         proxies={'http': f'http://{ip}:{port}'}, timeout=10), res = requests.
                         timeout=10)
        return res.status_code == 200
    except.
        return False

Level 2: Identity investigation - Go to https://ipleak.net看匿名级别 and show "Elite" to pass the test.

Level 3: Speed Test - Measure the response time with the curl command, if it is more than 3 seconds, it is recommended to throw it to the trash can directly.

The free agent pit is deeper than you think
