Etsy Crawler: Automatically Fetch Etsy Product Data

Don't be an ironhead when it comes to Etsy data, but understand why your IP is always blocked.

Recently a lot of cross-border e-commerce friends and I complained that the script to climb the Etsy commodity data is like bouncing in a minefield, not moving to trigger the ban. In fact, this thing really do not blame the platform cruel, think about it, if someone with a loudhailer in front of your store 24 hours shouting prices, you can stand it?

Here's the point:Etsy's anti-crawl mechanism specializes in targeting high-frequency request IPs to get things doneThe first thing you need to do is to get a 403 error. Assuming you're bombarded with your own server IP, you're guaranteed to get a 403 error in less than half an hour. What's worse, once the IP is flagged, the account may be restricted.

Choosing a proxy IP is like buying seafood, live well and use it for a long time.

There are two main types of proxy IPs on the market, let's use the food market analogy:

Here's an honorable mention for our own productsDynamic Residential Proxy for ipipgoTheir IP pool is automatically updated every day, just like a seafood market stocking up in the wee hours of the morning, to ensure that every request is made with a clean IP at the real user level.

Hands down, you can build a crawler that doesn't roll over.

To use a chestnut in Python, there are just three things at the core:Random Interval + Disguised Request Header + Proxy Rotation. Look at the Proxy Settings section:

import requests
import random
from time import sleep

proxies = {
    'http': 'http://user:pass@gateway.ipipgo.io:8000',
    'https': 'http://user:pass@gateway.ipipgo.io:8000'
}

headers_list = [
    {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0)...'} ,
    {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel...'}
]

def scrape_etsy(url): {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel...'} ]
    def scrape_etsy(url): try: response = requests.get()
        response = requests.get(
            url, headers=random.choice(headers_list), headers_list
            headers=random.choose(headers_list),
            headers=random.choice(headers_list), proxies=proxies,
            timeout=10
        )
        sleep(random.uniform(1.5, 3.5)) don't use fixed interval
        return response.text
    except Exception as e.
        print(f'Crawl error: {str(e)}')

Highlights:
1. in the proxy addressgateway.ipipgo.ioIt's their exclusive entrance.
2. Before each request to randomly select the User-Agent, do not use fake_useragent library (early anti-crawling stared at)
3. 时间用浮点数，模拟真人操作节奏

Old Driver's Guide to Avoiding Pitfalls

You can definitely use these blood lessons:
- Don't grab data at 3-6 a.m., when traffic anomalies are most noticeable
- Don't fight with CAPTCHA, deactivate the current IP immediately (ipipgo can change IP with one click).
- Product details page crawl interval is longer than the list page 30%
- Change request header parameter combinations once a week, don't use the same configuration for ages!

QA time: what you might want to ask

Q: Will using a proxy IP slow down the speed?
A：这得看代理质量，像ipipgo的节点自带智能路由，实测能控制在200ms以内，比某些免费代理快10倍不止。

Q: Can a blocked IP be resurrected?
A: Residential proxies are generally cooled for 24 hours to work, but it is recommended to directly change to a new IP. ipipgo's packages come with an automatic replacement function, which is blocked and switched immediately.

Q: Do I need to maintain my own IP pool?
A: Never! Your own IP pool is like keeping a tank of tropical fish, temperature and water quality are to worry about. Professional things to ipipgo this kind of service provider, their IP pool automatically updated every day 20% IP above.

One last rant:Doing data collection is like guerrilla warfareDon't always use fixed routines. Prepare a few more capture strategies, with a reliable proxy IP service (such as ipipgo), in order to have the last laugh in this cat and mouse game.
