Location Data Capture Tool: Geolocation Data Capture

Why does this thing have to use a proxy IP?

You old iron in the address data collection, certainly encountered this kind of shit: just grabbed not a few pages, the site will give you a pop-up verification code, or directly blocked IP. to cite a real case, there is a chain of stores to do site selection of friends, want to pick up a review of the site's store coordinates, the results of the use of their own network just run for half an hour, the entire company's network has been blacked out for three days.

This is where the magic weapon of the proxy IP comes into play. Simply putMake the server think you're accessing from different computers in different placesIt's like playing a game of "Change Face". For example, the Shanghai IP to grab two pages, immediately switch to Guangzhou IP to continue, the site wind control system is confused.

What are the doors to look for when choosing a proxy IP?

The market is full of proxy service providers, but there are also many pits. Let's use the table to speak human:

Here's the kicker.Geographic accuracySome proxy IPs show Beijing, but the actual server room may be in Tianjin. Professional service providers such as ipipgo can do base station level positioning, so that the map data will not wear gangs.

I'll show you how to do it.

Here is a Python code to realize automatic IP switching with ipipgo's service. pay attention to the comment section, it's all a lesson in blood and tears:

import requests
from itertools import cycle

 The ipipgo API to get a pool of proxies (remember to replace your account)
def get_ipipgo_proxies():
    api_url = "https://api.ipipgo.com/your_token"
    res = requests.get(api_url).json()
    return cycle([{
        'http': f "http://{ip}:{port}",
        'https': f "http://{ip}:{port}"
    } for ip, port in res['proxies']])

proxies_pool = get_ipipgo_proxies()

 Here's the kicker! Automatically change the IP for each request
def smart_scraper(url): for _ in range(5): Failure to retry 5 times.
    for _ in range(5): fail and retry 5 times
        proxy = next(proxies_pool)
        try: resp = requests.get(url)
            resp = requests.get(url, proxies=proxy, timeout=10)
            if "CAPTCHA" in resp.text: change IP immediately if trigger
                continue
            return resp.content
        except Exception as e.
            print(f "Rollover with {proxy}, reason: {str(e)}")
    return None

 Example: Grabbing data from a map API.
data = smart_scraper("https://example-map-api/data?area=浦东新区")

There are three in the codePoints for avoiding pitfalls1. used the IP pool cycle switching 2. added a timeout mechanism 3. automatic detection of CAPTCHA. This set of combination punch down, basically can handle 90% website anti-climbing.

Your most common pitfalls.

Q: Why is it still blocked after using a proxy?
A: eighty percent of the IP quality is not good, free agents are basically ten thousand people ride the IP. suggest using ipipgo's exclusive IP pool, each IP only a fixed number of times on the elimination.

Q: How many IPs are needed to be sufficient?
A: Depends on the frequency of capture, generally every 5 minutes to cut 1 IP is enough. If it is a high-frequency capture (such as 1 second 1 time), it is recommended to prepare 500 + IP rotation.

Q: How to verify the real location of the proxy IP?
A: ipipgo has an IP location detection tool in the background that shows the location of the base station to which the IP belongs, which is much more accurate than the IP libraries on the market.

Why does it have to be ipipgo?

To say an industry insider, many agents service providers IP are second-hand resale. And ipipgo directly with the three major carriers signed with the engine room cooperation, three points of advantage to crush peers:

1. Real residential IP covering 334 prefecture-level cities across the country
2. Up to 24 hours of uninterrupted connectivity per IP address
3. Self-requested fingerprint masquerade, perfect simulation of mobile access

Recently, they have an event to send 10G traffic for new users. Do address collection brother, you can first test the effect of free quota, than directly buy members reliable. Anyway, my team tested down, the same amount of tasks, with his family IP collection speed can be 3 times faster, the focus is no longer encountered IP blocked broken thing.
