Crawler development project: crawler project proxy IP integration configuration program

Crawlers must know the proxy IP doorway

Crawler brothers have encountered anti-crawler mechanism, right? IP blocking is like a common occurrence. At this time we need proxy IP to be a "stand-in actor" - with someone else's identity to visit the site. Like you go to the supermarket to buy things, every time you change a different membership card checkout, the cashier can not remember your spending habits.

Four Steps to Real-World Configuration

Tip #1: Pick the right type of agent

Residential IPs are like network IDs for real users and are suitable for scenarios that require a high degree of anonymity. For example, with ipipgo's dynamic residential IP, each request automatically switches outlets, and the website simply can't figure out the pattern.

 Python requests example
import requests

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

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

Tip #2: Be flexible with your rotation strategy

Don't be silly fixed IP, here to teach you a dirt method: every 5 pages to catch the IP change, or encounter 403 error immediately switch. ipipgo API extraction interface support on-demand access, do not have to worry about the IP pool is not enough.

How Enterprise Solutions Play

Anyone who has done e-commerce price monitoring knows that dozens of collection processes need to be opened at the same time. This time we need to use ipipgo's exclusive static IP, each crawler process is assigned a fixed IP, with intelligent routing features, perfect simulation of different regions user access.

// Scrapy middleware configuration
class IpipgoProxyMiddleware.
    def process_request(self, request, spider).
        request.meta['proxy'] = 'http://企业专属通道.proxy.ipipgo.com'
        request.headers['Proxy-Authorization'] = basic_auth_header('account', 'key')

QA time (real questions organized)

Q: Why is it still blocked after using a proxy?
A: Check three points: 1. whether to open cookie isolation 2. whether the request header with browser fingerprints 3. whether the frequency of visits like a real person

Q: How to speed up overseas websites?
A: Use ipipgo's cross-border line, such as grabbing the Japanese site on the Tokyo node, measured latency can be controlled within 200ms!

Budget-saving tips

Packages are selected based on the size of the project:
- Dynamic Standard Edition for small-scale testing ($7.67/GB)
- Static residence for long-term monitoring ($35/IP)
- Enterprise-level data collection directly to customer service to customize the program, can save 30% budget

Lastly, don't waste your time on free proxies. Last year, a brother used a free IP to get data, and the result was the implantation of mining scripts, and the server was directly paralyzed. Professional things or to ipipgo such regular army, after all, data security is real money.
