Download entire webpage (html, image, JS) by Selenium Python

I have to download source code of a website like www.humkinar.pk in simple HTML form. Content on site is dynamically generated. I have tried driver.page_source function of selenium but it does not download page completely such as image and javascript files are left. How can I download complete page. Is there any better and easy solution in python available?

Using Selenium

I know your question is about selenium, but from my experience I am telling you that selenium is recommended for testing and NOT for scraping. It is very SLOW. Even with multiple instances of headless browsers (chrome for your situation), the result is delaying too much.

Recommendation

Python 2, 3

This trio will help you a lot and save you a bunch of time.

Do not use the parser of dryscrape, it is very SLOW and buggy. For this situation, one can use BeautifulSoup with the lxml parser. Use dryscrape to scrape Javascript generated content, plain HTML and images.

If you are scraping a lot of links simultaneously, i highly recommend using something like ThreadPoolExecutor

Edit #1

dryscrape + BeautifulSoup usage (Python 3+)

from dryscrape import start_xvfb
from dryscrape.session import Session
from dryscrape.mixins import WaitTimeoutError
from bs4 import BeautifulSoup

def new_session():
    session = Session()
    session.set_attribute('auto_load_images', False)
    session.set_header('User-Agent', 'SomeUserAgent')
    return session


def session_reset(session):
    return session.reset()


def session_visit(session, url, check):
    session.visit(url)
    # ensure that the market table is visible first
    if check:
        try:
            session.wait_for(lambda: session.at_css(
                'SOME#CSS.SELECTOR.HERE'))
        except WaitTimeoutError:
            pass
    body = session.body()
    session_reset(session)
    return body

# start xvfb in case no X is running (server)
start_xvfb()

SESSION = new_session()
URL = 'https://stackoverflow.com/questions/45796411/download-entire-webpage-html-image-js-by-selenium-python/45824047#45824047'
CHECK = False

BODY = session_visit(SESSION, URL, CHECK)
soup = BeautifulSoup(BODY, 'lxml')

RESULT = soup.find('div', {'id': 'answer-45824047'})

print(RESULT)

I Hope below code will work to download the complete content of the page.

driver.get("http://testurl.com")
pageurl=driver.current_url
page = requests.get(pageurl)
pagecontent=page.content

`pagecontent` will contain the complete code content

It's not allowed to download a website without Permission. If you would know that, you would also know there is hidden Code on hosting Server, where you as Visitior has no access to it.
