Using a http proxy with headless firefox in Selenium webdriver in Python

问题

I'm using Firefox headless like this:

from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium import webdriver
import os
import sys

# Set the MOZ_HEADLESS environment variable which casues Firefox to
# start in headless mode.
os.environ['MOZ_HEADLESS'] = '1'

# Select your Firefox binary.
binary = FirefoxBinary('/usr/bin/firefox', log_file=sys.stdout)

# Start selenium with the configured binary.
driver = webdriver.Firefox(firefox_binary=binary)

But now I want to add a http proxy that requires a user/password. After searching around, I tried the following:

from selenium.webdriver.common.proxy import Proxy, ProxyType

myProxy = "xx.xx.xx.xx:80"

proxy = Proxy({
    'proxyType': ProxyType.MANUAL,
    'httpProxy': myProxy,
    'ftpProxy': myProxy,
    'sslProxy': myProxy,
    'noProxy': '' # set this value as desired
    })

driver = webdriver.Firefox(firefox_binary=binary, proxy=proxy)

I also tried

profile = webdriver.FirefoxProfile() 
profile.set_preference("network.proxy.type", 1)
profile.set_preference("network.proxy.http", "xx.xx.xx.xx")
profile.set_preference("network.proxy.http_port", 80)
profile.update_preferences() 
driver=webdriver.Firefox(firefox_binary=binary,firefox_profile=profile)

Finally, I tried adding "socksUsername" and "socksPassword" with the creds to the proxy, more out of desperation than any real hope.

Needless to say none of these works, and testing shows requests are still using my usual IP, not the proxy.

Also system-wide proxy is not an option in this case.

Where should the http proxy credentials live? How can I use a proxy with headless firefox?

Testing

driver.get("https://www.ipinfo.io");
driver.find_element_by_xpath('//h4/following-sibling::p').text

If your proxy requires a username and a password, you have to write it like that :

from selenium.webdriver.common.proxy import Proxy, ProxyType

myProxy = "username:password@proxyDomain:proxyPort"

proxy = Proxy({
    'proxyType': ProxyType.MANUAL,
    'httpProxy': myProxy,
    'ftpProxy': myProxy,
    'sslProxy': myProxy,
    'noProxy': '' # set this value as desired
    })

driver = webdriver.Firefox(firefox_binary=binary, proxy=proxy)

Have you try setting up a profile manually with

./firefox --ProfileManager

manually setup the proxy and then load the profile you manually set

from selenium import webdriver

url = "https://mail.google.com"
fp = webdriver.FirefoxProfile('/Users/<username>/Library/Application Support/Firefox/Profiles/71v1uczn.default')

driver = webdriver.Firefox(fp)

You can try setting up an Environment variable "HTTP_PROXY" in following mnemonics:

http://<username>:<password>@<proxy_url>

Add your credentials separated by colon ':' before proxy url that is preceded by '@' for e.g.

http://username:password@proxy.com:8080/file.pac
