eBay Data Crawl: US Residential IPs Get Product Information

When crawlers meet eBay: why is a normal IP not good enough?

Engaged in data collection of the old iron know, eBay this platform to prevent crawlers like a thief. Last year, there is a buddy with a common server room IP to catch price data, the result is less than two hours on the hi403 Bundle. Why is that? Because eBay recognizes it:

• Successive requests come from the same IP segment
• Frequency of visits as regular as a robot
• IP geographically erratic (e.g. New York and then LA)

That's when it's time to rely onResidential Proxy IPTo break the game. The most important feature of this type of IP is "like a real person", each IP corresponds to a real home broadband, access trajectory completely simulate the operation of real people.

Three Elements of Residential IP Selection

The market is full of proxy service providers, but you have to recognize these hard indicators to get eKay done:

It is important to mention here that ipipgo'sDynamic rotation mechanismTheir system automatically eliminates tagged IPs and gets a "freshly baked" residential address with every request.

Hands-on configuration of agents

In the case of the Python crawler, for example, only three lines of code need to be added with the requests library:

import requests

proxies = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:端口',
    'https': 'http://用户名:密码@gateway.ipipgo.com:端口'
}

resp = requests.get('https://www.ebay.com/itm/123456', proxies=proxies, timeout=10)

Be careful to puttimeoutSet between 8-12 seconds, too fast instead of easy to trigger the wind control. It is recommended to randomly hibernate for 2-5 seconds before each request, using time.sleep() to simulate a real person's browsing interval.

A practical guide to avoiding the pit

Last week, a customer feedback that the use of proxies or blocked, troubleshooting found that theCookies aren't clean.. Here are a few practical tips to share:

1. Browser fingerprinting must be reset every time you change IP (you can use the fake_useragent library)
2. Use different IP pools for product detail pages and search pages (ipipgo supports creating multiple IP groups)
3. Highest success rate for collection from 3-6am (US time)

If you are bombarded with captcha codes, don't rush to the coding platform. First, reduce the collection speed to less than 5 times per minute with ipipgo'sIP Quality Inspection APIFilter out high reputation IPs.

As a final rant, this data collection thing is about afig. economy will get you a long way. Instead of going for fast, you should go steady. Use the right tools (such as ipipgo) coupled with a reasonable strategy, in order to consistently and steadily get the data you want.
