You can't do data collection these days without a few tricks up your sleeve.
Buddy recently is not always encountered this kind of shit? Hard-written crawler script, running on the run on the hiatus, the site anti-climbing with the anti-thief like. This time we have to sacrifice the proxy IP banner, but the market those conventional play has long been stared dead. Today we nag some real, hand in hand to teach you to use alternative data collection techniques to break out.
The Three Deadliest Points of Traditional Proxy IP
Let's start with a few potholes that the guys have stepped in:
1. Repeated use of the same IP, the site directly affixed to your seal
2. The quality of IPs in the public proxy pool is akin to pumping a blind box.
3. dynamic authentication code jumped out at the moment, blood pressure directly spiked
It's time to think differently and get new meaning with alternative data proxies.
Alternative Data Acquisition Triple Axe
Tip #1: IP Mashups
Don't be available to an IP, use ipipgo's dynamic residential proxy and randomly change your horse's armor with each request. Their API automatically spits out fresh IPs like this whole:
import requests
from random import choice
proxies_pool = ipipgo.get_dynamic_proxies() call their API here
current_proxy = {'http': choice(proxies_pool)}
resp = requests.get('destination URL', proxies=current_proxy)
Tip #2: Request a Fingerprint Shift
It's not enough to change the IP, you have to change the request headers, cookies and all these features. Take a chestnut: Tip #3: Requesting a rhythm to bring the wind to your sails Recently there is a brother to do e-commerce price comparison, with ipipgo static residential agent to engage in price monitoring. At first, 300 times per hour to catch the old blocked, and then so adjusted: Q: What should I do if my proxy IP is slow as a snail? Q: How can I tell if a proxy IP is a real residence? Q: What package should I choose on a limited budget? Data collection is like playing guerrilla warfare, have to constantly change tactics. ipipgo their home is the most fragrant can be privately customized program, last time there is an overseas questionnaire buddies, specializing in a mix of dynamic residential + data center agent program, the detection rate directly from 30% down to 3%. Lastly, I would like to remind you that you have to be careful about using proxy IPs. Don't crash your web server, it's not a good idea to get into a lawsuit. The rational use of tools, in order to flow a long time, is not it?
headers = {
'User-Agent': random_ua_generator(),
'Accept-Language': random_lang(),
'Referer': fake_referer()
}
Don't be on time like a robot, add some random delays. Make it float between 0.5 and 3 seconds, so the site can't figure out the routine.A practical guide to avoiding the pit
concern
prescription
IP switching too often
Change to long-lasting static IP, single IP request no more than 200 times per day

question-and-answer session
A: Try ipipgo's cross-border line, their S5 protocol node latency can be pressed to below 200ms. If you still think it is too slow, directly on the exclusive static IP, 35 dollars to buy a dedicated channel.
A: Use this method of testing:
1. Check whois information to see the attributed operator
2. Visit whatismyipaddress.com to see the IP type
3. Test the survival time of the IP, real residential IP will not survive more than 24 hours
A: climbing data volume of the selection of dynamic standard version, 7 more than 1G enough to build a month. To stabilize long-term use, direct static residential monthly, although the unit price is higher but not easy to turn over.Say something from the heart.
