Python Web Grabber: Batch Download Tool

Speaking of people image batch download tutorial

Driven crazy by anti-crawling mechanisms? Today we use the most grounded way to talk about how to use Python to glean website images. We will focus on how to use proxy IPs and teach you how to bypass download restrictions.

Why do you always get your IP blocked?

A lot of sites are loadedTraffic Monitoring DogIt's like a security guard at the entrance of a supermarket. Frequent access to the same IP immediately triggers an alarm. This is where proxy IPs are needed toplay tricks on sb.The dynamic IP pool at ipipgo's house enables the server to think that every visit is a new user.

Preparation for opening the whole

1. Go to the ipipgo website to getFree Trial Pack（Don't say I didn't tell you.)
2. loaded requests and BeautifulSoup library
3. Prepare a reliable browser developer tool

 Install the required libraries
pip install requests bs4

The core code is written like this

Focus on the proxy settings section and use the ipipgo API to get dynamic IPs:

import requests
from bs4 import BeautifulSoup

def download_images(url):
    proxies = {
        "http": "http://用户名:密码@gateway.ipipgo.com:端口",
        "https": "http://用户名:密码@gateway.ipipgo.com:端口"
    }

    try.
        response = requests.get(url, proxies=proxies, timeout=10)
        soup = BeautifulSoup(response.text, 'html.parser')
         Image link extraction logic...
    except Exception as e.
        print("Failed to capture, automatically switching IPs to retry.")

Five Things to Do to Stay Alive

1. Don't grab it like it's chicken blood., add a time.sleep random pause
2. Don't be tough when you encounter CAPTCHA, change ipipgo'sHigh Stash IPmore effective
3. Do not use the download path in Chinese, be careful to report an error to find the North!
4. Set the timeout automatic retry mechanism, do not let the program stuck
5. Remember to store important data in encrypted form, not in plaintext.

Frequently Asked Questions QA

Q: What should I do if my proxy IP suddenly fails?
A: Use ipipgo's automatic replacement function, their IP pool is large enough to fail to automatically cut new IPs

Q：Download speed like a snail?
A: Check if you are using a free proxy, suggest changing ipipgo'sExclusive use of high-speed lines

Q: Will I be sued by the site?
A: Don't touch copyrighted images, abide by robots agreement, and buy genuine material for commercial use.

Say something from the heart.

I've used 7 or 8 proxies, but I ended up using ipipgo for a long time just to get a better idea of what to expect.be spared worryI'm not sure if you're going to be able to do that. Their IP survival detection is done very well, unlike some service providers to give the IP of eight out of ten is wasted. In particular, friends doing e-commerce to catch the competitor's picture, with a high stash of residential IP basically did not miss a hand.

Lastly, I would like to remind you that technology is a double-edged sword and can only be used in the right way for a long time. Don't be deadlocked when you encounter 403 errors, reasonably control the frequency of requests, with ipipgo's intelligent scheduling, basically solves the problem of 90% image capture.
