Crawler ip proxy: Crawler special high-storage proxy IP services

I. Crawlers are always blocked? You may lack a good vest

Crawlers understand that the biggest headache is theIP blockedIt's like when you go to the supermarket and always wear the same clothes. Just like you go to the supermarket to try to eat always wear the same clothes, the clerk sooner or later recognize you. Ordinary proxy IP is like a stall goods T-shirt, people's website a little glance will be able to recognize. Here's what we need to sayHigh Stash AgentsThe mystery - it can disguise your crawler as countless normal users and wipe even the access logs clean for you.

Let's take a real example: last year, there was a team doing price comparison system, using ordinary agents were blocked more than 30 times a day. After switching to ipipgo's high stash of proxies, they ran for a week without triggering the wind control. The secret is in theirTriple anonymization techniques, taking care of request headers, protocol fingerprints, and all these details exactly like a real browser.

Secondly, don't just look at the price of picking an agent, these points will kill you.

There are all sorts of agency services on the market, remember these three dead ends should never be touched:

Special reminder don't be greedy and choose a free agent, that thing is like paper mache, a poke will break. Before a buddy to climb the e-commerce data, the free agent to return to the data 10 times in 6 times is wrong, net delay.

Third, hand to teach you how to use ipipgo agent

Take the Python crawler as an example of a three-step process to access a high stash of proxies:

import requests

 The proxy address is found in the ipipgo backend
proxy = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:9020',
    'https': 'http://用户名:密码@gateway.ipipgo.com:9020'
}

 Remember to keep the session
session = requests.Session()
session.proxies = proxy

 Just do the normal request and leave the rest to the proxy
resp = session.get('https://目标网站.com')

Be careful to change your username and password to the one you registered with ipipgo, theirIntelligent Dispatch SystemThe fastest node is automatically selected. If you encounter certificate issues, adding {'verify': False} to the request header will fix it.
