Headless Browser: Stealth Capture Technology Explained

First, what is a headless browser? Why play stealth capture?

Let's talk about what this thing is. A headless browser is like a robot browser without eyes, it can work automatically but you can't see the interface. For example, it's like letting a program replace your hand to click web buttons, especially suitable for batch data collection or automated testing.

However, the problem is - websites hate this kind of mechanical operation and block IPs when they are caught.cloak of invisibilityThe service can be changed at any time, especially if it is a service like ipipgo. It's like playing a game to open a small number, blocked one can still cut a new number to continue to play.

Second, how to proxy IP to the headless browser to wear a cloak of invisibility?

Normal browser capture is like running around naked, and webmasters catch people with these three methods:
1. Look at the frequency of IP visits (crazy refreshing directly pull black)
2. Check if the User-Agent is a robot.
3. Detection of mouse trajectory (jittery in real life)

Proxy IP with ipipgo solves the first fatal problem. Their dynamic IP pool has these great tricks:

 Python example: using Selenium + ipipgo proxy
from selenium import webdriver

proxy = "123.123.123.123:8888" proxy address provided by ipipgo
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument(f'--proxy-server=http://{proxy}')

driver = webdriver.Chrome(options=chrome_options)
driver.get("https://目标网站.com") Now access with cloak!

Even if you use a proxy IP, these pits will still roll over if you don't pay attention:

1. User-Agent should be randomizedDon't always use the same browser fingerprints, ipipgo backend can automatically change this parameter!
2. Don't operate at regular intervals: Add random wait times to the code to mimic manual operations
3. Play dumb with CAPTCHA: Immediately pause the acquisition, change to a new IP and try again!

Focusing on the third scenario. When the site pops up a CAPTCHA, use ipipgo'sEmergency IP changeThe features are more cost effective than hardcoding. Their API changes a clean IP in three seconds, which is much cheaper than getting someone to code.

IV. QA Time: Minesweeper for Beginners' FAQs

Q：Collection is always blocked, is it because the quality of proxy IP is not good?
A: 80% of the IP switching strategy. ipipgo's intelligent routing can automatically avoid high-risk IP segments, ten times more reliable than manually changing IPs.

Q: What should I choose between a dynamic IP and a static IP?
A: dynamic for collection, static for long term login. ipipgo has both, and can also be used in combination

Q: Why is it still recognized even if I use a proxy?
A: Check that browser fingerprints are not exposed. ipipgo's deep camouflage mode can modify 12 browser parameters

V. Practical skills: e-commerce price monitoring cases

Let's talk about a real scenario: monitoring the price changes of 20 stores on a certain treasure. If you don't use a proxy, it will be blocked in half an hour. Use ipipgo's program:

1. Each store is assigned a separate IP
2. Setting up automatic daily IP pool change
3. Immediate switching of alternate routes in the event of back-climbing

This can be a stable run for three months without turning over. By the way, a tip: the collection time is set in the merchant's working hours, it looks more like a real person to compare prices.

Lastly, anecdotally, ipipgo recently made aFree trial for new users活动，注册就送5G流量。特别适合想试水的新手，反正不要钱，不上税嘛。
