Hands-on teaching you to use Python proxy IP to break through the collection restrictions

Engaged in crawling old drivers understand that the site's anti-crawler protection is like a cell access control, the same IP frequently in and out of the sure to be blocked. This time it is necessary toProxy IP ServiceTo use as an "access card", here are the recommendationsipipgoHome's Dynamic Residential Agent, the measured success rate can go up to 98%.

import requests
from random import choice

 API interface provided by ipipgo (remember to replace your account)
API_URL = "https://api.ipipgo.com/getproxy?format=json"

def get_proxies():
    resp = requests.get(API_URL).json()
    proxies = {
        'http': f "http://{choice(resp['data'])}",
        'https': f "http://{choice(resp['data'])}"
    }
    return proxies

 Example of collecting Jingdong product prices
url = 'https://item.jd.com/100000000001.html'
try.
    response = requests.get(url, proxies=get_proxies(), timeout=10)
    print(response.text)
except Exception as e.
    print(f "Failed to collect, suggest to check: 1. Proxy package margin 2. Request frequency setting")

Real-world debugging tips

Share a few debugging methods that have been personally tested to work:

1. Add aIP Verification Session, visit http://icanhazip.com确认IP是否生效 before each request

2. Don't rush to change your IP address when you encounter a 403 error.requests.Session()hold a conversation

3. Settingsstepwise delayThe waiting time is 0.5-3 seconds at different times of the day.

Package Selection Guide

Recommended based on project size:

• Small projects (<10,000 daily picks): experiential package (with 5 technical support sessions)
• Medium-sized projects: Professional package (supports concurrent API calls)
• Enterprise applications: customized private proxy pools (exclusive IP + dedicated egress)

Finally said a cold knowledge: ipipgo proxy IP library hourly update 15% IP pool, than some three days do not change the IP service provider is much more reliable. Encountered collection problems can be directly to their technical brother, the response speed than the takeaway customer service faster (personally measured the fastest 3-minute response).
