Data Aggregation Case: The Case of Proxy Data Aggregation System

Why is data aggregation always stuck on IP issues?

Do data collection friends understand that the most headache is the site anti-climbing mechanism. To give a chestnut, an e-commerce platform price monitoring script runs well, suddenly was blocked IP. this time if you use theProxy IP Rotation, it's like putting a million temporary IDs on the crawler, with a new vest for each request.

Recently, I helped a friend to get a travel price comparison system, using ordinary IP to grab data, on average, half an hour to be blocked. Later, it was replaced by a dynamic residential IP pool, which ran for three consecutive days without any problems. Here is a tip:Don't put your eggs in one basket.The IPs of different regions should be mixed, and the frequency of visits should be controlled within the affordable range of the website.

Hands-on building agent aggregation system

Let's start with the core logic:Request distribution → IP rotation → exception handling. Here's a demo of a basic framework in Python:

import requests
from itertools import cycle

 Proxy pool from ipipgo
proxies = [
    "http://user:pass@gateway.ipipgo.com:3000",
    "socks5://user:pass@gateway.ipipgo.com:3001"
]
proxy_pool = cycle(proxies)

def crawler(url): for _ in range(3): Failure retry mechanism
    for _ in range(3): failure retry mechanism
        current_proxy = next(proxy_pool)
        current_proxy = next(proxy_pool)
            resp = requests.get(url, proxies={"http": current_proxy}, timeout=10)
            return resp.text
        except.
            continue
    return None

Notice the use ofFailure auto switchmechanism, it will automatically change to the next one when it encounters IP failure. If the system is running for a long time, it is recommended to add an IP health detection module to eliminate failed nodes in real time.

E-commerce price monitoring real-world cases

During last year's Double Eleven, an apparel brand used our program to achieve competitor monitoring:

Here's the key point.Business Scenarios Matching IP Types: Static IPs are suitable for scenarios that require a fixed identity (e.g., account login), and dynamic IPs are suitable for high-frequency data collection.

White Frequently Asked Questions

Q: What can I do about slow proxy IPs?
A: Prioritize local carrier resources, such as ipipgo'sTK LineLatency can be controlled within 200ms. Remember to set a reasonable timeout in the code so that slow nodes don't drag down the overall speed.

Q: Should I choose dynamic or static package?
A: Depends on the business needs. Dynamic IP is suitable for crawler business (from $7.67/GB), and static IP is suitable for the scene that needs fixed IP (from $35/IP). If you are not sure, you can directly find ipipgo customer service to do program customization.

Why do you recommend ipipgo?

An honest word from a long time user who has used it for over three years:Consistency is real.The company's website is a great source of information on cross-border merchandise data aggregation. Last year to do cross-border commodity data aggregation, using their home cross-border line, 100,000 requests success rate can be 98% +. Several highlights are worth saying:

1. Clients come withone-click speed measurementFunction that automatically filters quality nodes
2. be in favor ofSERP APIDirect call, SEO friends to save a big deal
3. Enterprise-level packages can be customized on demand, like we do public opinion monitoring, we can specify the country + operator.

Recently releasedAPP ConfigurationIt's pretty convenient, and you can manage the IP pool from your cell phone when you're out and about. But be careful, don't buy IP services from small workshops on the cheap, many of them are public IP pools that fail en masse as you use them.

The last nagging sentence: do data aggregation is not more than who wrote the code, the key to look at the quality of resources. Choose the right proxy service provider, the project will be half successful. Don't be hard on the IP problem, try different combinations of programs, sometimes a different protocol type (such as HTTP to Socks5) can solve the problem.
