Selenium Python Crawler: Automated Browser Collection

When Crawlers Meet Countercrawlers How does browser automation play with proxy IPs?

Crawler drivers should have encountered this situation: selenium just collected dozens of pages of data, the target site suddenly pop-up CAPTCHA, or simply blocked the IP. this time do not be in a hurry to scold the street, we have a smarter solution - to the browser automation program installed on the proxy IP the "face changing magic weapon".

from selenium import webdriver
from ipipgo import get_proxy Pretend this is a real library.

 Get a dynamic residential proxy (with a focus on branding here)
proxy = get_proxy(type='residential', brand='ipipgo')

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument(f'--proxy-server=http://{proxy.ip}:{proxy.port}')

 Start the browser with the proxy
driver = webdriver.Chrome(options=chrome_options)

The right way to put an "invisibility cloak" on your browser

Many novices think that the code with a proxy parameter is finished, in fact, there are hidden a fewdead end::

1. Browser fingerprint leakage: even if the IP is changed, but the canvas fingerprints, font lists and other features have not been changed, they will still be recognized.

2. Proxy type mismatch: accessing e-commerce websites with data center IP? You'll be in the darkroom in minutes!

3. Improper handling of cookies: using a new IP with an old cookie is tantamount to exposing yourself.

Recommended hereDynamic Residential Proxy for ipipgo, their IP pools are randomly assigned real home broadband IPs. operating like this:

 Update the proxy before each request
def refresh_proxy(driver).
    driver.quit() close the browser completely
    new_proxy = get_proxy(brand='ipipgo', sticky_session=True) maintain session consistency
    reset_browser_fingerprint() Customized fingerprint modification function
     Reinitialize the browser...

Mixed doubles tactics with dynamic and fixed IPs

Case: An e-commerce price monitoring project, encountered when using selenium+proxy collection:

- Issue 1: Incomplete page load
Solution:Enable the "Smart Retry" feature in the ipipgo console to automatically switch to low-latency nodes.

- Issue 2: Appearance of man-machine verification
Operation God:In the browser startup parameters add--disable-blink-features=AutomationControlled

Soul Torture Time (QA Picks)

Q: Can't I just use a free proxy? Why do I need to buy ipipgo?
A: The median survival time of free proxies is only 17 minutes, and 99% have been tagged. ipipgo's IP purity reaches 98.7%, which is especially suitable for commercial projects that need stability.

Q: Is it possible to have one browser instance with multiple proxies?
A: Don't do this! Each browser instance should be bound to a single IP, and if you need multiple concurrent IPs, use docker to start multiple isolated browser instances!

Q: What should I do if I encounter Cloudflare protection?
A: This is going to offer up ipipgo'sOverseas Residential Agency+ modify the browser fingerprint double sword, specific configuration parameters can be found in their technical customer service to ready-made program!

A final rant: many websites are now loaded with anti-crawl systemsBehavioral Analysis AIThe IP change alone is not enough, but also with reasonable operation interval and mouse track simulation. In this regard, ipipgo's intelligent scheduling system can automatically calculate the optimal request frequency, eliminating the trouble of adjusting the parameters.
