E-commerce Data Capture: Product Information Collection Solution

Real Case: Why is e-commerce data capture always blocked?

Recently, there is a wholesale clothing boss to find me complaining, said they use the crawler to catch a wholesale website merchandise map, at first well, the results of the next day IP directly be pulled black. This thing is too common, now the e-commerce platform have learned the fine, anti-climbing mechanism than the train station security check is also strict.

Here's a cold one: most e-commerce platforms will be in theWithin 30 minutesBlock the fixed IP of continuous access, especially when grabbing product detail pages, price fluctuations of these sensitive data. Don't believe you try to use your own home broadband to catch half an hour, guaranteed to receive a 403 error.

How did proxy IPs become a lifesaver?

In fact, the principle is very simple, just like playing a game of chicken on stealth mode. For example, to catch a certain treasure 2000 product details, with their own broadband hard just, at most, to catch 50 on the cool. With a proxy IP, each request for a new "armor", the platform simply can not distinguish between a real person or machine.

Here is a pit to pay attention to: do not use free proxies! Last year, there was a guy who made digital accessories and used a free proxy pool to save time, but the data he got back was mixed withDuplicate information for 30%, and was almost sued by the platform. Later changed to ipipgo's exclusive IP, the average daily crawl directly soared to 20,000 items.

import requests
from itertools import cycle

 The format of the proxies provided by ipipgo
proxies = [
    "http://user:pass@gateway.ipipgo.com:30001",
    "http://user:pass@gateway.ipipgo.com:30002"
]

proxy_pool = cycle(proxies)

for page in range(1,100): current_proxy = next(proxy_pool)
    current_proxy = next(proxy_pool)
    try: current_proxy = next(proxy_pool)
        response = requests.get(
            f "https://mall.com/products?page={page}",
            proxies={"http": current_proxy}, timeout=10
            timeout=10
        )
        print(f "Page {page} captured successfully")
    except.
        print(f "Failed with {current_proxy}, automatically switching to next")

Hands-on guide to avoiding the pit

Name a few places where newbies tend to fall head over heels:

1. IP switching frequency is not as fast as it should be.

Don't think that cutting 10 IPs per second is a cow, the actual test cut 3-5 times per second is the most stable. A mother and baby products seller set to cut once every 2 seconds, continuous operation for 18 hours without being blocked.

2. Remember to disguise your browser fingerprints

The platform now detects User-Agent, Canvas fingerprints and all that. It's recommended to use the fake_useragent library to randomly generate headers and don't always use the same browser version.

3. Pay attention to API call limitations

ipipgo business package subscribers beware, their homeUp to 15 calls per secondThe API to get new IPs is 5 times for individual packages. Exceeding the limit will result in a temporary freeze, so keep that in mind.

The QA session you care most about

Q: Is it illegal to use a proxy IP?
A: Mere technology is not illegal, but crawling non-public data or bypassing platform protocols may be risky. It is recommended to look at the robots.txt file before crawling.

Q: How long does ipipgo's IP survive?
A: Dynamic residential IP is usually replaced automatically in 30 minutes, static enterprise IP can be fixed for 1-7 days. Do price monitoring with dynamic, inventory monitoring with static.

Q: How do I break the CAPTCHA when I encounter it?
A: ipipgo's enterprise version comes with a CAPTCHA recognition relay, ordinary users are advised to add 2-5 seconds random delay in the code, which can reduce the CAPTCHA triggering of 70%.

Why do you recommend ipipgo?

To be honest, I've tried basically every proxy service provider on the market. I finally chose ipipgo for three reasons:

Last month a friend who does cross-border work used his homeSoutheast Asia Dedicated IPGrab Lazada data, with Selenium simulation clicks, the average daily collection efficiency is 3 times faster than before.

Finally, a nagging word: data crawling is a protracted war, do not expect a set of programs to eat all day. It is recommended that every month to update the anti-anti-crawling strategy, ipipgo's technical consultants can help customize the program, than their own blind toss much stronger.
