IMDb Data Capture: IMDb Movie Data Proxy Collection

Why use a proxy IP to catch IMDb?

Recently a friend who makes movie and TV recommendations came to me to complain that when he was using a Python script to grab IMDb profiles, he got his IP blocked just after grabbing 200 pieces of data. This is too common! Big sites like IMDb haveIntelligent anti-climbing systemThe company's goal is to find unusual traffic that can be directly hacked. At this time it is necessary toproxy IPTo be a stand-in, it's like playing hide-and-seek with a constant change of vests so that the site doesn't recognize you for who you really are.

The Three Fateful Things About Choosing a Proxy IP

There are numerous agency service providers on the market, but not many of them are reliable. Remember these three key points:
1. IP purityIt has to be a residential IP, and the server room IP is a catch-all.
2. responsivenessDon't wait more than 1.5 seconds, or you'll be waiting for your food to get cold.
3. session hold: maintain a stable connection for at least 10 minutes

This is a must.ipipgoHome's Dynamic Residential Agent, measured to work for 6 hours straight without dropping out when grabbing data. They have a unique skill--IP Fingerprint Emulation TechnologyThe code below shows how to make each request look like it's coming from a different computer:

import requests

proxies = {
    'http': 'http://username:password@gateway.ipipgo.com:8080',
    'https': 'http://username:password@gateway.ipipgo.com:8080'
}

response = requests.get('https://www.imdb.com/title/tt0111161/', proxies=proxies, timeout=10)
print(response.text[:500]) print the first 500 characters of the test

A practical guide to avoiding pitfalls (with lessons learned through blood and tears)

I stepped on a mine last year when I was helping a data company with acquisition:
- No random delay set, 20 requests in 10 seconds will be blocked.
- I used a free proxy, but all I got back was phishing content.
- Forgetting to handle SSL authentication leads to loss of critical data

The correct posture should be:
1. Add 2-5 seconds of randomized waiting before each request
2. Periodic replacement of User-Agent
3. In conjunction with the use of ipipgo's auto-rotation feature (they have the ability to set the IP to change every 5 minutes in the background)
4. Be sure to check the HTTP status code, encountered 403 immediately switch IP

Five things you might get in trouble for

Q1：Why is it still blocked even though I have used a proxy?
A: Check if you are using a transparent proxy, ipipgo's high stash of proxies will hide your real IP tightly.

Q2: What should I do if the data is not fully loaded?
A: IMDb new version of the page with dynamic loading, you have to work with Selenium and other browser automation tools, remember to configure the proxy in Selenium as well:

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument('--proxy-server=http://username:password@gateway.ipipgo.com:8080')
driver = webdriver.Chrome(options=options)

Q3: What can I do if the crawl is too slow?
A: Use ipipgo's concurrent proxy service, they support multiple connections at the same time, be careful not to exceed the site's tolerance range

Q4: How do I break the CAPTCHA when I encounter it?
A: Reduce the frequency of requests, or use ipipgo's CAPTCHA retry function to automatically cut the IP

Q5: Where is the appropriate place to store data?
A: small amount of data with CSV, more than 100,000 suggested on MySQL, remember to backup regularly!

Say something from the heart.

If the proxy IP is used properly, the data will be captured with half the effort. The key is to choose the right service provider, like ipipgo, which can provide theReal Residential IPThe only reliable one is the one that you can rely on. Don't be greedy and use a free proxy, when the data is not captured instead of causing a fuss. Recently, their family is doing activities, new users to send 5G traffic, completely enough to test.

Final reminder: grab data to comply with the rules of the site, don't gripe hard with an IP. Set a reasonable collection frequency, with ipipgo intelligent scheduling system, basically can be as stable as the old dog. What do not understand can directly poke their customer service, reply speed than a treasure seller faster (personally measured 2 am are people back).
