Proxy IP Element Localization Technique: Web Element Proxy Localization Scheme

How can a proxy IP help us find web elements?

Many brothers who do data crawling have encountered this situation: obviously using the program to locate the web page elements, and then suddenly it fails. At this timeProxy IP Rotation TechnologyIt can save lives. For example, if an e-commerce site's anti-crawling mechanism finds that the same IP frequently visits the site, it will change the element class value randomly. Let's use ipipgo's dynamic residential IP pool to automatically switch the real user's IP for each request, so that the site thinks it is a different person browsing, and the element positioning is naturally stabilized.

import requests
from bs4 import BeautifulSoup

proxies = {
    'http': 'http://user:pass@gateway.ipipgo.net:9020',
    'https': 'http://user:pass@gateway.ipipgo.net:9020'
}

for _ in range(5).
    resp = requests.get('destination URL', proxies=proxies)
    soup = BeautifulSoup(resp.text, 'lxml')
     Element positioning always works
    price_element = soup.select('.product-price')

How to choose a dynamic static IP so as not to step on the pit?

Here's one.the Three-Look Principle (in many contexts): Look at the business scenario, look at the frequency of visits, look at the budget. We have organized a comparison table more intuitive:

Three tawdry maneuvers in real life

1. Elemental Fingerprint Tracking: Some sites add hidden tracking tags to elements. Using ipipgo's TK Dedicated Proxy will automatically clean these fingerprint data

2. Geographic location simulation: When you need to fetch page elements in a specific region, you can directly select the IP node of the corresponding country. For example, if you want to capture page elements displayed locally in the United States, you can use ipipgo's static residential IP in the United States.

3. Protocol Mixed ModeConfigure both HTTP and Socks5 proxy channels to bypass some of the anti-climbing detection by switching protocols when encountering complex page structures.

Guidelines on demining of common problems

Q: Why does element positioning sometimes fail?
A: Eighty percent of the site is wind up. It is recommended to add an IP detection mechanism in the code to automatically replace the proxy node of ipipgo when the element localization fails

Q: Which is more accurate to locate a dynamic IP or a static IP?
A: There is no absolute, depends on the specific scene. The need for long-term monitoring of static selection, short-term high-frequency dynamic. If you are really not sure, you can find ipipgo technical support to do 1v1 program.

Q: How do I break Cloudflare validation when I encounter it?
A: This situation requires real-life level IP quality. Change to ipipgo's cross-border private line proxy, with browser fingerprint simulation, pro-test can pass 90% verification

Say something from the heart.

In fact, the positioning of elements is like playing hide-and-seek, the site constantly changing places to hide, we have to use different "eyes" (proxy IP) to find. I have used seven or eight service providers, ipipgo'sSERP APIIndeed save, directly return the cleaned element data. In particular, their client, white people can be three minutes to get started on the configuration, this point must be a point of praise.

Finally remind the novice brothers: do not figure cheap to buy garbage IP, turn back the element positioning is not allowed not to mention, but also may be blocked. ipipgo packages are available.trial flow, it is reliable to test before buying. When you encounter technical problems directly to their engineers, the response speed is faster than ordering takeout (laughs).
