eBay Crawl: U.S. Residential IP for Product Data

Why do I have to use a U.S. residential IP to climb eBay?

Engaged in the e-commerce data capture know that eBay this platform is as fine as a monkey. Ordinary room IP just climbed two pages on the pop-up verification code, with the data center IP may not be directly blocked. This is the time to findHome network IP for real people, to put it bluntly, makes the site feel like it's being viewed by regular users.

For example, if the king next door to your house uses his own WiFi to swipe goods, the website will not suspect anything. Residential IP is equivalent to letting the crawler disguise itself as countless "old kings", and must beNative American Family IPIt's only when you can get accurate geographic data on commodity prices and inventories that you can get accurate geographic data.

Second, hand to teach you how to match the agent

Here's a chestnut with ipipgo's service, whose residential IPs are all solid home networks. Start by generating an API link in the backend in a format that looks like this:

http://username:password@gateway.ipipgo.com:端口号

If you use the requests library in Python, the code should be written like this:

import requests

proxies = {
    'http': 'http://user123:pass456@us-resi.ipipgo.com:32000',
    'https': 'http://user123:pass456@us-resi.ipipgo.com:32000'
}

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

Note that each request should ideallychange to a different IP, ipipgo background can be set to automatically switch the frequency. It is recommended that every 5-10 pages to climb the IP change, do not be available to a sheep.

Third, the anti-sealing strategy of the whole (form dry goods)

IV. QA session (a must for newbies)

Q: Why is it more expensive to use a residential IP than a regular proxy?
A: as if the difference between renting a house and living in a hotel, residential IP are real home broadband, ipipgo these resources are signed with the local operator of the agreement, the cost of shelving it.

Q: What should I do if I encounter a CAPTCHA?
A: First check if the IP is polluted, go to ipipgo background and change a new IP pool. If that doesn't work, you'll have to add an image recognition program, but that's another story.

Q: Will it conflict to have more than one crawler on at the same time?
A: Use ipipgo'smulti-threaded channelfunction, each thread is assigned a separate IP, remember to set the rate limit do not burst the bandwidth.

V. Don't step on these pits

1. don't buy the cheap kindTen Thousand Rides IPSome service providers have had their IP's blacked out by eBay.
2. 8:00 p.m. Beijing time (U.S. morning) to crawl the data success rate is higher, this cold knowledge not many people know
3. Encounter429 error codeDon't panic. Stop for half an hour and continue with the new IP.

To be honest, using residential IP to engage in crawlers is like playing chicken, both have to just gun and have to be meticulous. ipipgo this IP pool is updated quite often, recently found that they new on theIP Health DetectionFunction, which IP is flagged by the site will be automatically quarantined, is considered to be a lot of heartache.
