So nutzen Sie einen Proxy mit Selenium

# The proxy has your machine's IP on its whitelist, so no credentials
# are sent: Chrome ignores them in --proxy-server anyway.
from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument("--headless=new")  # remove to watch the browser
options.add_argument("--proxy-server=http://HOST:PORT")

driver = webdriver.Chrome(options=options)
try:
    driver.get("https://example.com/")
    print(driver.title)
finally:
    driver.quit()

# Selenium 4.51+ with WebDriver BiDi; pip install selenium
from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy, ProxyType

options = webdriver.FirefoxOptions()
options.enable_bidi = True
options.add_argument("-headless")  # remove to watch the browser
options.proxy = Proxy({
    "proxyType": ProxyType.MANUAL,
    "httpProxy": "HOST:PORT",
    "sslProxy": "HOST:PORT",
})

driver = webdriver.Firefox(options=options)
try:
    # Answers the proxy's 407 with your username and password
    driver.network.add_authentication_handler(
        lambda request: request.provide_credentials("USERNAME", "PASSWORD")
    )
    driver.get("https://example.com/")
    print(driver.title)
finally:
    driver.quit()

# The proxy has your machine's IP on its whitelist, so no credentials
# are sent. For a password instead, see selenium-firefox-auth.
from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy, ProxyType

options = webdriver.FirefoxOptions()
options.add_argument("-headless")  # remove to watch the browser
options.proxy = Proxy({
    "proxyType": ProxyType.MANUAL,
    "httpProxy": "HOST:PORT",
    "sslProxy": "HOST:PORT",
})

driver = webdriver.Firefox(options=options)
try:
    driver.get("https://example.com/")
    print(driver.title)
finally:
    driver.quit()

# Switch the proxy to SOCKS5 first, then use the port the order shows.
# The whitelist applies to SOCKS5 as well, so no credentials here either.
from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument("--headless=new")  # remove to watch the browser
options.add_argument("--proxy-server=socks5://HOST:PORT")

driver = webdriver.Chrome(options=options)
try:
    driver.get("https://example.com/")
    print(driver.title)
finally:
    driver.quit()

# Put the public IPv4 address your code runs from on the proxy's
# whitelist. Replaces the list; an empty list turns whitelisting off
# and the proxy falls back to username and password.
curl -X PUT "https://api.proxyjam.com/public/v1/orders/ORDER_ID/whitelist" \
