I want to scrap some data with selenium python. I have this type of screen sometimes :
Do you know to proceed in order to remove this type of verification ? Here my code :
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager
options = Options()
options.add_argument("start-maximized")
options.add_argument("--disable-web-security")
options.add_argument("--disable-site-isolation-trials")
options.add_argument("--allow-running-insecure-content")
driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=options)
driver.get('THE_WEBSITE_COM')
Selenium specifically and other automation tools have certain user agents and other identifiers which indicate that it's automated. So maybe have a play around with things like that. Some websites use anti bot tools to analyze browsing behaviours and patterns so try to slow it and randomize it eg. random time between page requests
Another trick is to look at the website and try to find if there are any alternative routes to get the information. For example: is there a public API you can use to bypass it? Is there a mobile version of the website? Sometimes mobile versions have less aggressive Captcha enforcement.
What I do most of the time is to launch the browser separately and connect to it using Dev port which is beautifully explained in this article.
To enable Chrome to open a port for remote debugging, we need to launch it with a custom flag –
chrome.exe --remote-debugging-port=9222 --user-data-dir="C:\selenum\ChromeProfile"
Then connect to the browser using this
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_experimental_option("debuggerAddress", "127.0.0.1:9222")
#Change chrome driver path accordingly
chrome_driver = "C:\chromedriver.exe"
driver = webdriver.Chrome(chrome_driver, chrome_options=chrome_options)
print driver.title

In non headless mode everything works fine.
In headless mode after giving mail based on screenshot I got the message that browser is not safe. As above solution with agent did not help.
I also tried solutions proposed in post google login working in without headless but not with headless mode
with no success.
Any other proposals ?
When headless mode is activated, the Navigator.Webdriver flag is set to true, which indicates that the browser is controlled by automation tools. The code below worked for me.
chrome_options.add_argument('--disable-blink-features=AutomationControlled')
This blog has some other options you could try.
https://piprogramming.org/articles/How-to-make-Selenium-undetectable-and-stealth--7-Ways-to-hide-your-Bot-Automation-from-Detection-0000000017.html
recently a scraper I made stopped working in headless mode. I've tried with both firefox and Chrome. Notable things are that I am using seleniumwire to access API requests, and that I am using ChromeDriverManager to get the driver. Current version for Chrome/93.0.4577.63.
I've tried modifying the User-Agent manually as can be seen in the below code, in case the website added some checks blocking HeadlessChrome/93.0.4577.63 which is the original User-Agent. This did not help.
When running the script in regular mode, it works. When running in headless mode, the below code would output [] meaning that driver.get(url) does not return any requests. I run this code daily and it stopped working on 8.9.2021 I think, during the day.
from selenium.webdriver.chrome.options import Options as chromeOptions
from seleniumwire import webdriver
from webdriver_manager.chrome import ChromeDriverManager
options = {
'suppress_connection_errors': False,
'connection_timeout': None
}
chrome_options = chromeOptions()
chrome_options.add_argument("--start-maximized")
chrome_options.add_argument("--incognito")
chrome_options.add_argument('--log-level=2')
chrome_options.add_argument("--window-size=1920,1080")
chrome_options.add_argument("--disable-extensions")
chrome_options.add_argument('--allow-running-insecure-content')
chrome_options.add_argument('--headless')
driver = webdriver.Chrome(ChromeDriverManager().install(), seleniumwire_options=options, chrome_options=chrome_options)
userAgent = driver.execute_script("return navigator.userAgent;")
userAgent = userAgent.replace('Headless', '')
driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": userAgent})
url = 'my URL goes here'
driver.get(url)
print(driver.requests)
Same issue with FireFox, headless does not work but regular browsing does. Any idea what might cause this problem and what could solve it? I've also tried adding the following arguments to Chrome options without any luck:
chrome_options.add_argument("--proxy-server='direct://'")
chrome_options.add_argument("--proxy-bypass-list=*")
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--ignore-certificate-errors')
chrome_options.add_argument('--headless')
chrome_options.add_argument('--ignore-certificate-errors-spki-list')
chrome_options.add_argument('--ignore-ssl-errors')
This may have been solved - I noticed that I first set the window size to maximize and after that set it to 1920,1080. When I removed the argument to maximize
chrome_options.add_argument("--start-maximized") the problem disappeared and now the script works once again.
I'm not sure if this actually solved it or whether it was something else, since Selenium is a bit finicky and sometimes data just won't load the same way for the same web page, but at least now it works.
I am trying to scrape some data from LV website with Selenium and keep getting 'Access Denied' screen once 'sign in' button clicked. I feel like there is a protection against this because all seems to be working fine when I do the same manually. Oddly, I need to click 'sign in' button twice to be able to sign in manually.
My code:
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
options = webdriver.ChromeOptions()
options.add_argument("start-maximized")
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(options=options, executable_path=r'chromedriver.exe')
driver.get('https://secure.louisvuitton.com/eng-gb/mylv')
WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.XPATH, "//span[#class='ucm-wrapper']")))
driver.find_element_by_xpath("//button[#class='ucm-button ucm-button--default ucm-choice__yes']").click()
driver.find_element_by_id('loginloginForm').send_keys('xxx#xxx.com')
driver.find_element_by_id ('passwordloginForm').send_keys('xxxxxx')
driver.find_element_by_id('loginSubmit_').click()
Error:
You don't have permission to access "http://secure.louisvuitton.com/eng-gb/mylv;jsessionid=xxxxxxx.front61-prd?" on this server.
Is there a way to login with Selenium and bypass this?
I took your code added a few tweaks and ran the test as follows:
Code Block:
from selenium import webdriver
driver.get('https://secure.louisvuitton.com/eng-gb/mylv')
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//span[text()='Accept and Continue']"))).click()
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[#id='loginloginForm']"))).send_keys("Mudyla#stackoverflow.com")
driver.find_element_by_xpath("//input[#id='passwordloginForm']").send_keys('Mudyla')
driver.find_element_by_xpath("//input[#id='loginSubmit_']").click()
Observation
Similar to your observation, I have hit the same roadblock with no results as follows:
Deep Dive
It seems the click() on Sign In does happens. But while inspecting the DOM Tree of the webpage you will find that some of the <script> tag refers to JavaScripts having keyword akam. As an example:
akam-sw.js install script version 1.3.3 "serviceWorker"in navigator&&"find"in[]&&function()
<script type="text/javascript" src="https://secure.louisvuitton.com/akam/11/7f0e2ae6" defer=""></script>
<noscript><img src="https://secure.louisvuitton.com/akam/11/pixel_7f0e2ae6?a=dD0xOWNjNTRjMmMxYzdmNmMwZjI0NTUwOGZmZDM5ZTQzMWQ5NjI5ZmIwJmpzPW9mZg==" style="visibility: hidden; position: absolute; left: -999px; top: -999px;" /></noscript>
Which is a clear indication that the website is protected by Bot Manager an advanced bot detection service provided by Akamai and the response gets blocked.
Bot Manager
As per the article Bot Manager - Foundations:
Conclusion
So it can be concluded that the request for the data is detected as being performed by Selenium driven WebDriver instance and the response is blocked.

It's been a while since I had posted this question but if anyone is interested below are the steps I've taken to solve the problem.
Open chromedriver.exe in hex editor, find the string $cdc and replace with something else of the same length. Then save and run modified binary. Read more in this answer and the replies to it.
Selenium python code:
options = webdriver.ChromeOptions()
options.add_argument("start-maximized")
options.add_argument('--disable-blink-features=AutomationControlled')
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(options=options, executable_path='chromedriver.exe')
driver.execute_script("Object.defineProperty(navigator, 'webdriver', {get: () => undefined})")
driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) '
'AppleWebKit/537.36 (KHTML, like Gecko) '
'Chrome/85.0.4183.102 Safari/537.36'})
For me it worked when I added the following line just after launching a driver:
driver.manage().deleteAllCookies();
I'm working on a python script to web-scrape and have gone down the path of using Chromedriver as one of the packages. I would like this to operate in the background without any pop-up windows. I'm using the option 'headless' on chromedriver and it seems to do the job in terms of not showing the browser window, however, I still see the .exe file running. See the screenshot of what I'm talking about. Screenshot
This is the code I am using to initiate ChromeDriver:
options = webdriver.ChromeOptions()
options.add_experimental_option("excludeSwitches",["ignore-certificate-errors"])
options.add_argument('headless')
options.add_argument('window-size=0x0')
chrome_driver_path = "C:\Python27\Scripts\chromedriver.exe"
Things I've tried to do is alter the window size in the options to 0x0 but I'm not sure that did anything as the .exe file still popped up.
Any ideas of how I can do this?
I am using Python 2.7 FYI
It should look like this:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument('--headless')
options.add_argument('--disable-gpu') # Last I checked this was necessary.
driver = webdriver.Chrome(CHROMEDRIVER_PATH, chrome_options=options)
This works for me using Python 3.6, I'm sure it'll work for 2.7 too.
Update 2018-10-26: These days you can just do this:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.headless = True
driver = webdriver.Chrome(CHROMEDRIVER_PATH, options=options)
Answer update of 13-October-2018
To initiate a google-chrome-headless browsing context using Selenium driven ChromeDriver now you can just set the --headless property to true through an instance of Options() class as follows:
Effective code block:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.headless = True
driver = webdriver.Chrome(options=options, executable_path=r'C:\path\to\chromedriver.exe')
driver.get("http://google.com/")
print ("Headless Chrome Initialized")
driver.quit()
Answer update of 23-April-2018
Invoking google-chrome in headless mode programmatically have become much easier with the availability of the method set_headless(headless=True) as follows :
Documentation :
set_headless(headless=True)
Sets the headless argument
Args:
headless: boolean value indicating to set the headless option
Sample Code :
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.set_headless(headless=True)
driver = webdriver.Chrome(options=options, executable_path=r'C:\path\to\chromedriver.exe')
driver.get("http://google.com/")
print ("Headless Chrome Initialized")
driver.quit()
Note : --disable-gpu argument is implemented internally.
Original Answer of Mar 30 '2018
While working with Selenium Client 3.11.x, ChromeDriver v2.38 and Google Chrome v65.0.3325.181 in Headless mode you have to consider the following points :
You need to add the argument --headless to invoke Chrome in headless mode.
For Windows OS systems you need to add the argument --disable-gpu
As per Headless: make --disable-gpu flag unnecessary --disable-gpu flag is not required on Linux Systems and MacOS.
As per SwiftShader fails an assert on Windows in headless mode --disable-gpu flag will become unnecessary on Windows Systems too.
Argument start-maximized is required for a maximized Viewport.
Here is the link to details about Viewport.
You may require to add the argument --no-sandbox to bypass the OS security model.
Effective windows code block :
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("--headless") # Runs Chrome in headless mode.
options.add_argument('--no-sandbox') # Bypass OS security model
options.add_argument('--disable-gpu') # applicable to windows os only
options.add_argument('start-maximized') #
options.add_argument('disable-infobars')
options.add_argument("--disable-extensions")
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\path\to\chromedriver.exe')
driver.get("http://google.com/")
print ("Headless Chrome Initialized on Windows OS")
Effective linux code block :
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("--headless") # Runs Chrome in headless mode.
options.add_argument('--no-sandbox') # # Bypass OS security model
options.add_argument('start-maximized')
options.add_argument('disable-infobars')
options.add_argument("--disable-extensions")
driver = webdriver.Chrome(chrome_options=options, executable_path='/path/to/chromedriver')
driver.get("http://google.com/")
print ("Headless Chrome Initialized on Linux OS")

tl; dr
Here is the link to the Sandbox story.
Update August 20, 2020 -- Now is simple!
chrome_options = webdriver.ChromeOptions()
chrome_options.headless = True
self.driver = webdriver.Chrome(
executable_path=DRIVER_PATH, chrome_options=chrome_options)
UPDATED
It works fine in my case:
from selenium import webdriver
options = webdriver.ChromeOptions()
options.headless = True
driver = webdriver.Chrome(CHROMEDRIVER_PATH, options=options)
Just changed in 2020. Works fine for me.
So after correcting my code to:
options = webdriver.ChromeOptions()
options.add_experimental_option("excludeSwitches",["ignore-certificate-errors"])
options.add_argument('--disable-gpu')
options.add_argument('--headless')
chrome_driver_path = "C:\Python27\Scripts\chromedriver.exe"
The .exe file still came up when running the script. Although this did get rid of some extra output telling me "Failed to launch GPU process".
What ended up working is running my Python script using a .bat file
So basically,
Save python script if a folder
Open text editor, and dump the following code (edit to your script of course)
c:\python27\python.exe c:\SampleFolder\ThisIsMyScript.py %*
Save the .txt file and change the extension to .bat
Double click this to run the file
So this just opened the script in Command Prompt and ChromeDriver seems to be operating within this window without popping out to the front of my screen and thus solving the problem.
The .exe would be running anyway. According to Google - "Run in headless mode, i.e., without a UI or display server dependencies."
Better prepend 2 dashes to command line arguments, i.e. options.add_argument('--headless')
In headless mode, it is also suggested to disable the GPU, i.e. options.add_argument('--disable-gpu')
Try using ChromeDriverManager
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.set_headless()
browser =webdriver.Chrome(ChromeDriverManager().install(),chrome_options=chrome_options)
browser.get('https://google.com')
# capture the screen
browser.get_screenshot_as_file("capture.png")

ChromeDriver driver = new ChromeDriver(chromeOptions);

don't forget to add spaces between ${BROWSER} options
There is an option to hide the chromeDriver.exe window in alpha and beta versions of Selenium 4.
from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService # Similar thing for firefox also!
from subprocess import CREATE_NO_WINDOW # This flag will only be available in windows
chrome_service = ChromeService('chromedriver', creationflags=CREATE_NO_WINDOW)
driver = webdriver.Chrome(service=chrome_service) # No longer console window opened, niether will chromedriver output
You can check it out from here. To pip install beta or alpha versions, you can do "pip install selenium==4.0.0.a7" or "pip install selenium==4.0.0.b4" (a7 means alpha-7 and b4 means beta-4 so for other versions you want, you can modify the command.) To import a specific version of a library in python you can look here.
RECENT UPDATE
Recently there is an update performed on headless mode of Chrome. The flag --headless is now modified and can be used as below
For Chrome version 109 and above, --headless=new flag allows us to explore full functionality Chrome browser in headless mode.
For Chrome version 108 and below (till Version 96), --headless=chrome option will provide us the headless chrome browser.
So, let's add
options.add_argument("--headless=new")
for newer version of Chrome in headless mode as mentioned above.
The below works fine for me with Chrome version 110.0.5481.104
chrome_driver_path = r"E:\driver\chromedriver.exe"
options = webdriver.ChromeOptions()
options.add_argument('--disable-gpu')
//New Update
options.add_argument("--headless=new")
options.binary_location = r"C:\Chrome\Application\chrome.exe"
browser = webdriver.Chrome(chrome_driver_path, options=options)
browser.get('https://www.google.com')
Update August 2021:
The fastest way to do is probably:
from selenium import webdriver
options = webdriver.ChromeOptions()
options.set_headless = True
driver = webdriver.Chrome(options=options)
options.headless = True is deprecated.
