Zillow Capture: Real Estate Data Collection Solution

Zillow Crawl Headache? Try these wildcards

Doing real estate data analysis brothers understand, Zillow's data is very expensive, but directly on the hands of the crawl in less than half an hour will be blocked IP. However, if you climb directly, you will be blocked in less than half an hour. last year, a buddy did not believe in the evil, and used his own broadband to catch three days in a row, and as a result, the entire community network was blacklisted by Zillow, causing the neighbors to complain collectively. This thing tells us thatWithout a proxy IP, it's a death wish to mess with data.The

Proxy IP Selection with Care

There are two types of proxy IPs on the market, just like buying groceries is divided into live and frozen fish:

Catching sites like Zillow that are hard on anti-crawl is recommended to use theDynamic residential IP for ipipgoThe website simply can't figure out the routine as they keep more than 20 million real home IPs in their home IP pool and change their vest every time they request it.

Hands-on configuration

Using Python's old buddy requests library as an example, configuring it with ipipgo's proxy service is thief simple:

import requests

proxies = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:9020',
    'https': 'http://用户名:密码@gateway.ipipgo.com:9020'
}

response = requests.get('https://www.zillow.com/homes', proxies=proxies)

Remember to putRequest intervals are adjusted to more than 3 secondsIf you are too fast, you will be easily recognized even if you change your IP address. There is a tricky way to add a random delay in the code to mimic the operation of a real person:

import time
import random

time.sleep(random.uniform(2.5, 6.8))

Anti-blocking must-kill three-piece set

1. IP rotation should be tasty enough: new IP for each request, ipipgo's API supports automatic switching
2. The request header has to be real enough.: Don't use the default Python-UA, go steal a proper User-Agent from your browser!
3. Access paths should be sufficiently heterogeneous: Don't catch a page in the weeds, mimic the click path of a real person.

Tell the truth.

I've seen too many people use free proxies for cheap, and the result is that the data is not gained but also causes a lot of trouble. ipipipgoResidential Agent PackageAlthough it is more expensive than IP, it is more stable. Last time I had a friend who was a real estate agent and used their service for three months, but Zillow didn't find out.
