如何隐藏浏览器处于SeleniumWebdriver控制状态？解决验证码验证差异

Hey, I’ve dealt with this exact problem countless times—those anti-bot systems are sharp at picking up Selenium’s default traces. Here are the most reliable fixes to get back to that simple checkbox captcha:

1. Disable Chrome’s Automation Flag #

Chrome’s dead giveaway is the window.navigator.webdriver property and the "Automation Controlled" notification. You can squash both by adding specific launch arguments to your Selenium setup:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
# This is the key flag to bypass detection
chrome_options.add_argument("--disable-blink-features=AutomationControlled")
# Add other flags to mimic a real browser session
chrome_options.add_argument("--start-maximized")
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument("--disable-dev-shm-usage")
# Optional: Disable extensions and pop-ups
chrome_options.add_argument("--disable-extensions")
chrome_options.add_argument("--disable-popup-blocking")

driver = webdriver.Chrome(options=chrome_options)

2. Use Undetected-Chromedriver (The Easiest Fix) #

If manual flag tweaks feel too tedious, undetected-chromedriver is a modified Selenium ChromeDriver built specifically to evade anti-bot detection. It handles all the hidden tweaks automatically:

First install it:

pip install undetected-chromedriver

Then use it like this (super similar to standard Selenium, but with better stealth):

import undetected_chromedriver as uc

# Initialize the driver with default stealth settings
driver = uc.Chrome()
driver.get("your-target-url-here")

This library often skips straight to the simple checkbox captcha because it masks all of Selenium’s usual fingerprints.

3. Mimic Real User Behavior #

Even with stealth tweaks, robotic-looking actions can trigger stricter captchas. Add these touches to make your script act human:

• Random waits: Instead of fixed time.sleep(2), use time.sleep(random.uniform(1.5, 3.5)) between actions.
• Mouse movements: Use Selenium’s ActionChains to move the mouse around randomly before clicking elements.
• Scroll first: Scroll up/down the page a bit before interacting with the captcha.
• Avoid instant navigation: Open a blank page first (driver.get("about:blank")), wait a second, then load your target URL.

4. Tweak Browser Fingerprint (Advanced) #

For extra stubborn sites, you can further mask your browser identity:

• Set a realistic user-agent: Grab a current Chrome UA string and add it via chrome_options.add_argument("user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/118.0.0.0 Safari/537.36")
• Override the webdriver property: Run this script right after launching the driver to hide the webdriver flag:

  driver.execute_script("Object.defineProperty(navigator, 'webdriver', {get: () => undefined})")
  

Combining these methods should get you past the puzzle captchas and back to the simple checkbox. Start with undetected-chromedriver—it’s the most foolproof option for most cases.
