Web Crawler: Web Crawler Proxy IP Settings Guide

Why do web crawlers need to change their vests?

Crawler friends have encountered this situation: just grabbed a few hundred pieces of data, the target site will give you a blocked IP. At this timeproxy IPIt's like wearing a vest to the crawler, so that the server can not recognize your true identity. For example, with ipipgo's dynamic residential IP, each request is randomly switched to a different area of the network outlet, the site simply can not feel your real way.

Choose a dynamic or static IP?

Here's a common misconception: many people think that expensive is necessarily good. Actually, it depends on the business scenario:

For example, it's more cost-effective to do price monitoring with a dynamic package, whereas a ticket-grabbing script may require a static IP to stay logged in.

Hands-on with proxy IPs

Using Python's requests library as an example, set it up like this after getting the proxy with the ipipgo API:

import requests

 API link from ipipgo backend
proxy_api = "https://api.ipipgo.com/get?format=json"

 Replace with your own key for actual use
proxies = {
    'http': 'http://用户名:密码@gateway_address:port',
    'https': 'https://用户名:密码@gateway address:port'
}

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

Notice there's a pit here:Never write account passwords explicitly in the code., it is recommended to store sensitive information with environment variables.

Stealth techniques for the Scrapy framework

}

IPIPGO_PROXY_LIST = [
    'http://ipipgo动态代理入口'.
     Multiple entries can be rotated
]

def get_proxy().
    return random.choice(IPIPGO_PROXY_LIST)
