How to set up PROXY in Python for PhantomJS Node launched via Selenium grid HUB?

Question

Python

Raised Selenium server grid:

java -jar selenium-server-standalone-2.53.1.jar -role hub

Launched PhantomJS nodes (50 instances):

java -jar selenium-server-standalone-2.53.1.jar -role webdriver -hub http://localhost:4444/grid/register -browser "browserName=phantomjs, version=ANY, platform=WINDOWS, maxInstances=50, timeout=90000"

I checked the server and the nodes if they got up: 127.0.0.1:4444/grid/console

Run the python code:

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
driver = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub',  desired_capabilities=DesiredCapabilities.PHANTOMJS)
driver.get('http://www.SiteForScrape.com')

It works without problems
But you need to run it through a proxy . I
found it on the net:

driver.command_executor._commands['executePhantomScript'] = ('POST', '/session/$sessionId/phantom/execute')
driver.execute('executePhantomScript', {'script': '''phantom.setProxy("94.20.21.38", 3128);''', 'args' : [] })

Added, but the answer is an error:

selenium.common.exceptions.WebDriverException: Message: POST /session/a95e422b-420d-44c3-b67e-c62e8939ee50/phantom/execute

What is the problem or how to set proxy for Remote Webdriver PhantomJS?

Answer 1

Pss.... It turned out to be very simple:

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
webdriver.DesiredCapabilities.PHANTOMJS['proxy']={"httpProxy":'94.20.21.38:3128', "proxyType":"MANUAL"}
driver = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub',  desired_capabilities=DesiredCapabilities.PHANTOMJS)
driver.get('https://www.iplocation.net/')
x=driver.find_element_by_xpath('//p[contains(text(),"Your public IP Address is")]')
if x is not None: print x.text
