Web Data Crawling: Web Proxy Crawling Service

Why do I need a proxy ip for web data crawling?

Brothers who engage in web page data capture understand that the most headache is theIP blockedThe first thing that you need to do is to write a crawler script. For example, if you write a crawler script and then run it for half an hour, the website will pull your IP. The proxy ip is like the resurrection coin in the game, change the ip and can continue to work.

The average user may not realize that many websites are loaded withAnti-Crawler Radar. For example, 50 visits in 30 seconds in a row will definitely trigger an alert. With ipipgo's Dynamic Residential Proxy, each request changes to a real user IP in a different region, and the site can't tell if it's a real person or a machine.

How to choose a proxy ip without stepping on the pit?

There are all kinds of agency services on the market, remember these threeThe pitfall avoidance mnemonic.::

Focusing on ipipgo'sIntelligent switching mode: After setting the number of failed retries, the system will automatically change the IP to continue crawling. Let's say you want to crawl the price data of an e-commerce platform, set 5 retries, even if you encounter a CAPTCHA, you can bypass it.

Teach you to allocate proxy ip by hand

Here's a hands-on Python example, using the requests library + ipipgo's proxy service:

import requests

proxies = {
    'http': 'http://username:password@gateway.ipipgo.com:端口',
    'https': 'http://username:password@gateway.ipipgo.com:端口'
}

response = requests.get('destination URL', proxies=proxies, timeout=10)
print(response.text)

Be careful to replace username with the account you registered with ipipgo, and password with the authentication key they provide. It is recommended to addtimeout parameterto prevent one IP from getting stuck and affecting the overall progress.
