this is my code:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument("--headless")
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get("https://google.com/")
Yet the browser opens instead of going headless.
Some other arguments do seem to work like --start-maximized
This is redundant but, since I've been asked to do it, https://developers.google.com/web/updates/2017/04/headless-chrome says that headless won't be available on Chrome for Windows until version 60.
Headless won't be available on Windows untill Chrome 60.

When I run chrome driver from selenium the browser opens in minimized windows. but I want it to open by default as maximized
You can either use
driver.maximize_window() or
chrome_options.add_argument("--start-maximized") which will maximize the browser when ever it opens.
The following code was taken from this link. https://pythonbasics.org/selenium-maximize/
from selenium import webdriver
import time
driver = webdriver.Firefox()
driver.maximize_window()
time.sleep(5)
driver.get("https://www.python.org")
This is one of the methods to do so.
I have been using Selenium and python to web scrape for a couple of weeks now. It has been working fairly good. Been running on a macOS and windows 7. However all the sudden the headless web driver has stopped working. I have been using chromedriver with the following settings:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("--headless")
options.add_argument('--no-sandbox')
options.add_argument('--disable-gpu')
chrome_options.add_argument("--window-size=1920x1080")
driver = webdriver.Chrome(chrome_options=options)
driver.get('url')
Initially I had to add the window, gpu and sandbox arguments to get it work and it did work up until now. However, when running the script now it gets stuck at driver.get('url'). It doesn't produce an error or anything just seems to run indefinitely. When I run without headless and simply run:
from selenium import webdriver
driver = webdriver.Chrome()
driver.get('url')
it works exactly as intended. This problem is also isolated to my windows machine. Where do I start?
Solved
For some reason the proxy setting was slowing it down. Therefore it got solved by adding:
options.add_argument(f'--proxy-server={None}')
I had exactly the same problem. It appeared randomly after the script has run fine for weeks. OP has led me to the right direction, but his solution doesnt worked for me. I had to add:
chrome_options.add_argument("--no-proxy-server")
chrome_options.add_argument("--proxy-server='direct://'");
chrome_options.add_argument("--proxy-bypass-list=*");
My complete code:
chrome_options = Options()
chrome_options.add_argument("--headless")
chrome_options.add_argument("--start-maximized")
chrome_options.add_argument("--start-fullscreen")
chrome_options.add_argument("--no-proxy-server")
chrome_options.add_argument("--proxy-server='direct://'");
chrome_options.add_argument("--proxy-bypass-list=*");
chrome_options.binary_location = "C:\Program Files (x86)\Google\Chrome Dev\\Application\chrome.exe"
browser = webdriver.Chrome(options=chrome_options)
browser.set_window_size(2000, 1080)

Headless chrome driver too slow
and:
Chrome webdriver produces timeout in selenium
I'm using Chrome with Selenium in Python 2.7.
I've tried to run Chrome in headless mode but it slows down my tests significantly.
One workaround shall be to disable the proxy settings but I don't know how to do it in python.
This is my code so far:
from selenium import webdriver
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--disable-extensions")
chrome_options.add_argument('headless')
chrome_options.add_argument('--hide-scrollbars')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('???') # which option?
self.driver = webdriver.Chrome("C:\Python27\Scripts\chromedriver.exe", chrome_options=chrome_options)
Does anyone know how to solve this?
Try this:
chrome_options.add_argument('--no-proxy-server')
I can drive a headless browser using selenium and Chrome Canary.
But I can't get it to work using Splinter.
Thanks in advance.
Here's what works.
import os
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument("--headless")
chrome_options.binary_location = '/Applications/Google Chrome Canary.app/Contents/MacOS/Google Chrome Canary'
driver = webdriver.Chrome(executable_path='/usr/local/bin/chromedriver', chrome_options=chrome_options)
Here's what doesn't work:
from splinter import Browser
executable_path = {'executable_path':'/Applications/Google Chrome Canary/Contents/MacOS/Google Chrome Canary'}
B=Browser('chrome',**executable_path)
Incidentally Splinter DOES work with phantomjs
executable_path = {'executable_path':'/Applications/phantomjs/bin/phantomjs'}
B=Browser('phantomjs',**executable_path )
The error message is
WebDriverException: Message: 'Google Chrome Canary' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home
Here's the path, as perceived by os.os.environ['PATH']
/Users/jonschull-MBPR/miniconda2/bin:/Applications/Google Chrome Canary/Contents/MacOS/Google Chrome Canary:/Users/jonschull-MBPR/miniconda2/bin:/Users/jonschull-MBPR/anaconda/bin:/Users/jonschull-MBPR/Downloads/google-cloud-sdk/bin:/opt/local/bin:/opt/local/sbin:/Users/jonschull-MBPR/anaconda/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/chromedrive:/opt/X11/bin:/usr/local/mongodb/bin
And by the way, I've tried escaping "Google\ Chrome\ Canary "
Well, according to issue in splinter's git you just need to upgrade to splinter 0.7.6+.
I am currently trying to code a basic smartmirror for my coding II class in high school with python. One thing I'm trying to do is open new tabs in full screen (using chrome). I currently have it so I can open url's, but I am not getting them in full screen. Any ideas on code I can use to open chrome in full screen?
If you're using selenium, just code like below:
from selenium import webdriver
driver = webdriver.Chrome()
driver.get('https://google.com')
driver.maximize_window()
As suggested, selenium is a good way to accomplish your task.
In order to have it full-screen and not only maximized I would use:
chrome_options.add_argument("--start-fullscreen");
or
chrome_options.add_argument("--kiosk");
First option emulates the F11 pressure and you can exit pressing F11. The second one turns your chrome in "kiosk" mode and you can exit pressing ALT+F4.
Other interesting flags are:
chrome_options.add_experimental_option("useAutomationExtension", False)
chrome_options.add_experimental_option("excludeSwitches", ["enable-automation"])
Those will remove the top bar exposed by the chrome driver saying it is a dev chrome version.
The complete script is:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_experimental_option("useAutomationExtension", False)
chrome_options.add_experimental_option("excludeSwitches", ["enable-automation"])
# chrome_options.add_argument("--start-fullscreen");
chrome_options.add_argument("--kiosk");
driver = webdriver.Chrome(executable_path=rel("path/to/chromedriver"),
chrome_options=chrome_options)
driver.get('https://www.google.com')
"path/to/chromedriver" should point to the chrome driver compatible with your chrome version downloaded from here
