Python Image Crawling: Residential Proxies to Download Web Images

Hands-on with Python to capture images without getting blocked

Engage in crawling friends the biggest headache is the IP is blocked, especially when the batch download pictures. Today we nag how to use the residential agent stable local gripping pictures, take the reliable ipipgo service as an example, this trick can let you crawl live longer.

Why do you have to use a residential agent?

Ordinary agents are like plastic bags in the wholesale market, the site can be recognized at a glance as bulk goods. Residential agents are a real home network, like wearing a cloak of invisibility. Here's a comparison table:

Four Steps to Real-World Operation

Step 1: Load the necessary tools

pip install requests
pip install beautifulsoup4

Step 2: Get ipipgo's proxy configuration

Log in to the ipipgo backend to find access information, and note that you have to select theResidential Agent Package, their dynamic residential proxy is best suited for image capture. The connection address looks like this: gateway.ipipgo.com:8000

Step 3: Write a crawler with a proxy

import requests
from bs4 import BeautifulSoup

proxies = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:8000',
    'https': 'http://用户名:密码@gateway.ipipgo.com:8000'
}

response = requests.get('Target site', proxies=proxies, timeout=10)
soup = BeautifulSoup(response.text, 'html.parser')
 Write the image download logic here...

Step 4: Exception handling should be in place
Don't fight hard when you encounter a 429 status code, take a break and try again:

import time

try: response = requests.get(url, proxies=proxies)
    response = requests.get(url, proxies=proxies)
except requests.exceptions.
    ProxyError: time.sleep(5)
     Automatically switching ipipgo's standby node

Common pitfalls QA

Q: What about slow agents?
A: Go with ipipgo'sExclusive Residential AgentI'm not sure if it's a good idea to use a shared pool, but I'm sure it's a good idea. The actual download speed can be up to 3MB/s, and it doesn't lag when you play HD pictures.

Q: How do I know the agent is in effect?
A: Add a test to the code:

check_url = 'http://httpbin.org/ip'
resp = requests.get(check_url, proxies=proxies)
print(f'Current IP: {resp.json()["origin"]}') 

The fine points of choosing a proxy service provider

There are all sorts of agents on the market, so focus on three things:

1. IP Purity (ipipgo has real life residential certifications)
2. Connection stability (they have automatic compensation for broken wires)
3. After-sales response speed (pro-test customer service must return within 5 minutes)

Finally give a piece of advice: do not try to cheap with a free agent, especially under the picture of this bandwidth-eating operation. ipipgo new users have 5G flow trial, enough to run a small project. Encountered CAPTCHA problems can find their technology to customize the program, than their own toss to save a lot of heart.
