Data Capture: Best Proxy IP Services for Efficient Data Collection

Why is data capture always blocked? You may be missing this magic tool

The old iron have engaged in data crawling know that the target site's anti-crawl mechanism is like a watchdog - a little inattention will be blocked IP. last month a friend doing e-commerce complained that their team wrote a crawler program (such as Python's Requests library) just ran for half an hour, the server IP will be blacklisted, anxious to jumped straight to his feet. This is the time toProxy IP Servicedebuted - simply put, it's a way for different IPs to take turns doing their jobs, turning a single fight into a group fight.

How to choose a proxy IP so as not to roll over

There are all sorts of proxy IPs on the market, remember these three pit avoidance guides:

Here's the kicker.High Stash AgentsThis kind of proxy will hide your real IP tightly. Like we use ipipgo service, each request automatically change IP, pro-test run for three consecutive days did not trigger anti-climbing.

Hands-on configuration of proxy IP

Take Python's Requests library as a chestnut, three lines of code and you're hooked up to an agent:

import requests

proxies = {
  'http': 'http://user:pass@proxy.ipipgo.com:8080',
  'https': 'http://user:pass@proxy.ipipgo.com:8080'
}

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

Note that you have to replace user and pass with the password of the account you registered with ipipgo. If you are using the Scrapy framework, add these lines in settings.py:

DOWNLOADER_MIDDLEWARES = {
    'scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware': 543,
}

IPIPGO_PROXY = "http://proxy.ipipgo.com:8080"

Practical anti-blocking secret open

It's not enough to have an agent, you have to go along with these tawdry operations:

1. random hibernation: Don't ask continuously like a machine gun, use time.sleep to stop randomly for 0.5-3 seconds.
2. Fake Header: Don't use the same User-Agent all the time, have Chrome and Firefox on hand.
3. fail and try again: Take a break when you get a 429 status code and fight again in 15 minutes.

Frequently Asked Questions QA

Q: Can't I use the free agent?
A: Free ones are like roadside stands - they can be bad for you. We've tested that free proxies are available for less than 20%, and it's better to leave the professional stuff to a paid service like ipipgo.

Q: What should I do if my proxy IP is slow?
A: It's important to choose the right service provider! ipipgo's BGP lines have an average response speed of <200ms, which is twice as fast as many others. If you still think it's too slow, you can apply for their exclusive IP package.

Q: How can I tell if a proxy is in effect?
A: Visit http://ip.ipipgo.com/checkip to see the currently used export IP. It is recommended to write a timed check script to automatically replace the IP when it is found to be invalid.

Q: What are the advantages of ipipgo that you recommend?
A: three hard-core highlights: ① global 5 million + dynamic IP pool ② 7 × 24 hours technical customer service ③ support pay per volume, use how much counts how much is not wasted. New user registration also sends 20 times the number of tests, try it yourself to know whether it smells good or not.

Say something from the heart.

Proxy IP thing is like a lock picking tool - it's a godsend if you use it well, and something will happen if you use it carelessly. Comply with the robots.txt rules of the target website, don't catch a website to death. Don't be ironic when it comes to CAPTCHA, just go to the coding platform. The technology is not as good as the compliance operation, remember!
