Data collection proxy IP skills: anti-climbing to break through IP restrictions program

Getting blocked for data collection? Try this face-swapping trick

Do crawl brothers understand, the most headache is the other site suddenly give you a face - either blocking IP, or popping CAPTCHA. At this time do not hard just, change a vest and then do is serious. Here said the vest, that isproxy IPI'm not sure if you're going to be able to do that. To give you a chestnut, it's like when you go to the supermarket to try out the food, and people won't recognize you if you change your hat.

Dynamic IP seventy-two changes

Dynamic residential IPs are definitely an anti-crawl nemesis, especially with a program likeipipgo's dynamic residential packagesThe price of more than 7 bucks for 1G is like no money at all. The point is to set up a good rotation frequency, do not change 800 times per second like a rash, it is recommended that every 5-10 requests for a change.

import requests
proxies = {
    'http': 'http://user:pass@ipipgo-proxy.com:8080',
    'https': 'http://user:pass@ipipgo-proxy.com:8080'
}
 Remember to look like a real person in the headers
response = requests.get(url, proxies=proxies, headers={'User-Agent':'Mozilla/5.0'})

IP Quality Screening Triple Axe

Don't think you can just grab a proxy and use it, the rotten IP will make you turn over in minutes. I'm going to teach you three tricks of the trade:

1. Measurement delays:Throw it away if it's more than 800ms
2. Look at the agreement:Prioritize HTTPS encrypted channel
3. Checking blacklists:Use ipipgo's API to sift through a round first

There's something to be said for speed control.

The pace of collection is like gopher hunting; too fast and you get hammered, too slow and you lose money. Suggestion:

With ipipgo'sDedicated Static IP, 35 bucks a month, stability pulls right through.

Don't be lazy with the validation mechanism

It is recommended to do a real person verification every 20 requests:
1. Random mouse trajectory
2. Loading a graphic resource
3. Visit an unrelated page and jump back
It's a much better trick to make the anti-crawl system think you're alive than to just take a hard line.

As a final rant, anti-climbing confrontation is like a game of cat and mouse. The key is toflexible and changeableDon't expect to be able to use one program for everything. Another advantage of using ipipgo is to be able to cut the country node at any time, encountered a difficult site to change the regional IP to try, guaranteed to have a surprise.
