如何在Selenium（Python+Chrome）中通过代理加载HTTPS网站？

1. Confirm Proxy Supports HTTPS Traffic #

Most HTTP proxies block the CONNECT method required to tunnel HTTPS traffic. Test your proxy directly with curl to verify:

curl -x http://118.69.134.2:80 https://httpbin.org/ip

If this command fails, your proxy doesn’t handle HTTPS—switch to a proxy that explicitly supports both HTTP and HTTPS protocols.

2. Explicitly Define Proxy Protocols #

Some setups require separate proxy configurations for HTTP and HTTPS. Update your --proxy-server argument to include both:

from selenium import webdriver
from selenium.webdriver.common.by import By

proxy_config = "http://118.69.134.2:80;https://118.69.134.2:80"
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument(f'--proxy-server={proxy_config}')
driver = webdriver.Chrome(options=chrome_options)
driver.get("https://httpbin.org/ip")
print(driver.find_element(By.TAG_NAME, "body").text)
driver.quit()

3. Add Proxy Authentication (If Required) #

If your proxy uses username/password authentication, include credentials directly in the proxy URL:

http_proxy = "http://your_username:your_password@118.69.134.2:80"

Note: Avoid hardcoding credentials in production code—use environment variables instead.

4. Rule Out SSL Certificate Issues (Test Only) #

Temporarily disable Chrome’s SSL verification to check if certificate errors are causing the timeout (never use this in production):

chrome_options.add_argument('--ignore-certificate-errors')
chrome_options.add_argument('--ignore-ssl-errors')

5. Test with a Functional Proxy #

The proxy 118.69.134.2:80 may be offline or blocked. Try a known-working proxy to confirm the issue isn’t specific to this server.
