Web Crawling Application: Proxy Web Crawling Scenarios

Why is web crawling always blocked? You may be missing this magic tool

Engaged in data capture know that the most headache is the target site suddenly give you an IP ban. Obviously, the code is well written, the results just run half an hour on the shutdown, this kind of thing who meets all have to be crazy. For example, there is a price comparison system buddy, for three consecutive days by an e-commerce platform blocked more than 20 IP, almost ate the keyboard in a hurry.

Proxy IPs are your cloak of invisibility

Simply put, a proxy IP is like putting a piece of armor on your crawler.cloak of invisibilityThe target server will think that it is a different user. Every time you visit the website, you will change your "armor", so that the target server will think that it is operated by a different user. It's like going to the supermarket to buy a drink and changing your clothes every time you go to the checkout, so the cashier won't recognize you as the same person.

Here we should focus on ipipgo's dynamic residential proxy, their IP pool is really big. Last time, a team doing public opinion monitoring tested it, requesting a social platform for 72 hours in a row and changing 3000+ IPs without being recognized. How does it work? Look at this Python example:

import requests

proxies = {
    'http': 'http://username:password@gateway.ipipgo.com:9020',
    'https': 'http://username:password@gateway.ipipgo.com:9020'
}

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

Three types of agents how to choose not to waste money

There are three types of proxies in the ipipgo house, so let's start with this comparison table:

For example, if you want to do inventory monitoring, you can use the standard version, but if you want to grab limited commodities, you have to use the enterprise version. Their TK dedicated line measured latency can be pressed to 200ms or less, more than twice as fast as ordinary lines.

Avoid these potholes to make your crawler steady as an old dog

Ever seen someone with an open proxy and still get banned? 80% of them made these two mistakes:

1. Switching frequency is too rigidDon't be silly and cut IPs every second, making it look like a robot clocking in. ipipgo clients have smart modes that mimic the rhythm of a real person's actions!

2. lit. harden one's head against the CAPTCHAThe first thing you need to do is to get on the coding platform. There is a real estate data old brother, the proxy IP and the combination of coding services, the collection efficiency directly tripled!

Configuration tricks that even a novice can handle

Fear of trouble directly with ipipgo's client, three steps in place:

① Download their PC software
② Select the desired region/IP type
③ Tap the big lightning connection button

For advanced play you can try their API extraction, which supports filtering IPs by country, city and even carrier. e.g. if you only want to use Beijing Unicom's IP, just pass a parameter and you're done.

Frequently Asked Questions

Q: Does proxy IP slow down the speed?
A: A good agent but faster! ipipgo's cross-border line measured download speeds up to 5MB / s, more stable than their own broadband!

Q: What's special about the Enterprise program?
A: In addition to higher IP quality, we can also customize the request header and support UDP protocol. There is a cross-border e-commerce customer, after using the enterprise version of the collection success rate soared from 68% to 93%.

Q: Can I still use my blocked IP?
A: Dynamic IP is blocked will automatically enter the cooling pool, 24 hours after the resurrection. Static IP is blocked can find customer service for free to replace the new

Lastly, don't just look at the price when choosing a proxy service. Like ipipgo can provide 1 to 1 program customization, encounter problems with real technical support, the critical moment can save the emergency. Last time I had a friend who did financial data, it was by their customized program to break through the counter-climbing of an exchange, this thing is enough to blow half a year.
