Price monitoring proxy: real-time price comparison system dedicated proxy IP

What exactly does a price monitoring agent do?

Engaged in e-commerce understand, peer price can change eight hundred times a day. Manually staring? Eyes have to see blind! This is the time to usereal time price comparison systemAutomatically grab data. But there is a pitfall: use your own computer to grab directly, and you will be blacklisted by the target website in minutes.

To cite a real case: a clothing seller for 3 consecutive days with a fixed IP to catch the price of competitors, the fourth day suddenly found that theAll data becomes 404. This is a typical case of an IP being blocked, and it's time to use a proxy IP tochange of armorOperation.

The Three Fateful Things About Choosing a Proxy IP

Not all agents are suited for price monitoring, and these three metrics should be watched:

This is a must.ipipgoHome of the Dynamic Residential Agent, they have a dark technology:Automatic switching of city operators per requestThe first time I saw this, it was a very good thing that I was able to get it to work. The last time a customer used his IP to capture an e-commerce platform, 24 hours for 7 days to capture did not trigger the wind control, the success rate remained at 98.6% or more.

Hands-on configuration tutorial

Write the simplest demo in Python (don't copy it, change the parameters to suit your situation):

import requests

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'
}

response = requests.get('Target product link', proxies=proxies, timeout=10)
print(response.text)

Note these two key points:
1. Do not set the timeout more than 10 seconds, otherwise it will affect the efficiency of the crawl.
2. Mandatory openingautomatic retry mechanismThe backend of ipipgo has an intelligent routing function, which will automatically cut the line when it encounters a lag

Maintaining the wild side of the proxy pool

Don't think you can buy a proxy and everything will be fine, these tawdry maneuvers can extend the life of your IP:

① Staggered Collection: Spread out monitoring tasks from 1-5am, when server defenses are at their most lax.
② traffic camouflage: add random referer parameters to the request header, pretending to jump from a different channel
(iii) cooling mechanism: Switch at least 5 IPs of different provinces per hour for the same target website.

There is a customer who does 3C products, after configuring ipipgo proxy according to this method, the average IP survival cycle is raised from 3 days to 23 days, and the maintenance cost is directly reduced by 60%.

Tell the truth.

A bunch of proxy service providers on the market blowing sky-high, the actual test down a lot of even the basic anti-climbing strategy can not carry. Our team has measured 7 service providers, ipipgo in the price monitoring scenariosComprehensive price/performance ratioCan indeed fight. Especially with theirDynamic mixing technologyThe combination of being able to call a data center + a residential IP at the same time works especially well against harsh anti-crawl systems.
