Five Pitfalls Enterprises Fall Into When Playing with Data Capture
Do data collection of the old iron should understand, the site anti-climbing mechanism is now more than a security door is also strict. Last week an e-commerce price comparison system customers and I complained that they use their own office network to capture data, the result is less than two hours IP was blocked to death. What's worse is that the whole company's network was blacked out, which affected everyone's normal Internet access.
The five most common pitfalls here must be singled out:
1. Single IP High Frequency Request(Websites are not stupid, 50 consecutive visits from the same IP will trigger an alert)
2. request header information reveals the cloven footage(Using Python's default request header is like sticking "I'm a crawler" in your head.)
3. CAPTCHA brute force cracking（"Dynamic CAPTCHA can make you doubt your life now.)
4. The way the data is loaded is not understood(Still think all the data is in HTML? Ajax requests can leave you empty-handed)
5. What to do when your IP is blocked(A lot of teams are still using the stone-age method of re-routing)
What does a true-enterprise solution look like?
Let's take a cross-border e-commerce case that ipipgo has served. The customer wants to capture the price of goods in 20 countries in real time, at first, we used traditional proxy pools, and as a result, we had to change 300+ IPs every day, and we always lost data. Later, they switched toDynamic port binding + request feature masqueradingPrograms, three core changes:
Example: Automatically switching proxies on Python requests
import requests
from ipipgo import RotatingProxy
proxy = RotatingProxy(api_key='your_ipipgo_key')
for page in range(1,100): current_proxy = proxy.
current_proxy = proxy.get()
session = requests.Session()
session.proxies = {"http": current_proxy, "https": current_proxy}
Remember to add the random request header!
response = session.get(url, headers=random_headers())
What's so great about this program?Operational level agent poolThere are three brushes:
- Each request is automatically assigned a different geographic IP (supports precise location by country and city)
- Intelligent randomization of request intervals (0.5-3 seconds floating, perfect simulation of real people)
- Automatic cleaning of failed IPs (more than 3 failures to automatically kick out of the pool)
Don't underestimate the technical details
Many teams have major misconceptions about proxy IP usage, such as thinking that you can just get a proxy pool and be done with it. Actually think about it:
| wrong posture | correct handling |
|---|---|
| IP switching frequency fixed | Random delay + dynamic switching |
| just change the IP address without changing the request header | Synchronized update of device fingerprint per request |
| Stick to a certain site. | Intelligent triage to different collection nodes |
Special note: when using ipipgo remember to open theprotocol obfuscationFunction. This black technology can disguise your request as normal traffic, the real test of a large e-commerce platform's interception rate from 78% straight down to 12%.
A practical guide to avoiding the pit
Here's a freebie for everyone who stepped on a mine last year while helping a financial company with public opinion monitoring:
1. Don't fight with CAPTCHA, use ipipgo'sIP Cooling MechanismAutomatic cutover to standby node
2. The collection frequency must not be a whole point blast (for example, every hour on the hour to open the capture), add a random time offset
3. Recommended configuration of critical data sourcesDual channel acquisition(both residential and server room IPs)
Five questions you definitely want to ask
Q: How big does the IP pool need to be to be adequate?
A: According to our experience of serving 300+ enterprises, daily mining of 100,000 level data suggests 500+ dynamic IPs, and million level requires 2000+ IP pools. ipipgo's elastic expansion function can be expanded on demand at any time.
Q: Can a blocked IP be resurrected?
A: Sub-situation! Ordinary blocking ip ipgo will automatically quarantine 12 hours, if it is permanently blocked IP, our system will be permanently culled and replenished with new IP within 30 minutes.
Q: Do I need to maintain my own proxy server?
A: Never! We have a customer who builds his own proxy cluster, and the O&M cost is higher than the value of the data. ipipgo provides a fully managed service, from IP allocation to performance monitoring, all in one place.
Q: Are there differences in agency programs for different industries?
A: Sure! For example:
- E-commerce acquisition to switch IPs at high frequency
- Social Media Needs to Stabilize Long Sessions
- Financial data requires more IP purity
ipipgo supports the creation of independent agent pools for multiple business scenarios.
Q: How can I tell if a proxy service provider is reliable?
A: Remember the three hard indicators:
1. Availability ≥ 99.51 TP3T (available on ipipgo real-time monitoring dashboard)
2. Whether there is an IP recovery mechanism (our invalid IP is automatically replaced within 30 seconds)
3. Whether to support customized geographic distribution (e.g., as long as the IP in East China)
Finally, to be honest, data collection is like guerrilla warfare, the fight is aFast, steady, and stealthy.The first step is to choose the right proxy IP service provider. Choose the right proxy IP service provider, at least to help the technical team to save 60% against anti-climbing energy. After all, professional things should be handed over to the professional ipipgo to do, why bother to toss a half-dead and still do not see the results?
