I am trying to scrape https://www.controller.com/ with python, and since the page detected a bot using pandas.get_html, and requests using user-agents and a rotating proxy, i resorted to using selenium webdriver. However, this is also being detected as a bot with the following message. Can anybody explain how can I get past this?:
Pardon Our Interruption...
As you were browsing www.controller.com something about your browser made us think you were a bot. There are a few reasons this might happen:
You're a power user moving through this website with super-human speed.
You've disabled JavaScript in your web browser.
A third-party browser plugin, such as Ghostery or NoScript, is preventing JavaScript from running. Additional information is available in this support article.
To request an unblock, please fill out the form below and we will review it as soon as possible"
Here is my code:
from selenium import webdriver
import requests
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys
options = webdriver.ChromeOptions()
options = webdriver.ChromeOptions()
options.add_argument("start-maximized")
options.add_argument("disable-infobars")
options.add_argument("--disable-extensions")
#options.add_argument('headless')
driver = webdriver.Chrome(chrome_options=options)
driver.get('https://www.controller.com/')
driver.implicitly_wait(30)
You have mentioned about pandas.get_html only in your question and options.add_argument('headless') only in your code so not sure if you are implementing them. However taking out minimum code from your code attempt as follows:
Code Block:
from selenium import webdriver
options = webdriver.ChromeOptions()
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:\Utility\BrowserDrivers\chromedriver.exe')
driver.get('https://www.controller.com/')
print(driver.title)
I have faced the same issue.
Browser Snashot:
When I inspected the HTML DOM it was observed that the website refers the distil_referrer on window.onbeforeunload as follows:
<script type="text/javascript" id="">
window.onbeforeunload=function(a){"undefined"!==typeof sessionStorage&&sessionStorage.removeItem("distil_referrer")};
</script>
Snapshot:
This is a clear indication that the website is protected by Bot Management service provider Distil Networks and the navigation by ChromeDriver gets detected and subsequently blocked.
Distil
As per the article There Really Is Something About Distil.it...:
Distil protects sites against automatic content scraping bots by observing site behavior and identifying patterns peculiar to scrapers. When Distil identifies a malicious bot on one site, it creates a blacklisted behavioral profile that is deployed to all its customers. Something like a bot firewall, Distil detects patterns and reacts.
Further,
"One pattern with Selenium was automating the theft of Web content", Distil CEO Rami Essaid said in an interview last week. "Even though they can create new bots, we figured out a way to identify Selenium the a tool they're using, so we're blocking Selenium no matter how many times they iterate on that bot. We're doing that now with Python and a lot of different technologies. Once we see a pattern emerge from one type of bot, then we work to reverse engineer the technology they use and identify it as malicious".
Reference
You can find a couple of detailed discussion in:
Distil detects WebDriver driven Chrome Browsing Context
Selenium webdriver: Modifying navigator.webdriver flag to prevent selenium detection
Akamai Bot Manager detects WebDriver driven Chrome Browsing Context
Distil can detect if you are headless by doing some fingerprinting using html5 canvas. They also check things like browser plugins and user-agent. Selenium sets some browser flags that are also detectable.
Finally solved the problem and headless mode works as well.
chrome_options = Options()
chrome_options.add_argument("--disable-extensions")
chrome_options.add_argument("--headless")
driver = webdriver.Chrome("chromedriver.exe", options=chrome_options)
driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.53 Safari/537.36'})
driver.execute_script("Object.defineProperty(navigator, 'webdriver', {get: () => undefined})")

I’m attempting to connect to the below website using selenium but the browser is held on a page which says “we’re making sure you’re not a bot”, which I believe is a Cloudflare block.
url: https:// www .aston martin austin. com /
Despite the page saying that it will connect after 5 seconds the browser is held on this site for longer. Implementing a sleep period sometimes results in the site loading, however, on other occasions the browser remains on this page without reaching the site.
I’ve tested various approaches including using a variety of chrome options (see code for a full list), selenium-wire to match headers against those when loading the site manually, a while loop with multiple gets and wait periods in between (which occasionally works - why is this?), but no method that I can code so far has proved to consistently work time after time i.e. connect to the home page first time. I've also tried changing the $cdc variable in the chrome driver executable.
The undetected-chrome package is the one package that does seem to work, however, I’d like to learn and understand which change I can make to my own code to make consistent successful requests without the help of an additional package.

Note – spaces should be removed from the URL when testing.
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
options = webdriver.ChromeOptions()
options.add_argument("window-size=1200x600")
options.add_argument("--headless")
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option("useAutomationExtension", False)

options.add_argument("--enable-javascript")
options.add_argument("javascript.enabled")
options.add_argument("--lang=en-US,en;q=0.8")
options.add_argument("--incognito")
options.add_argument("start-maximized")
options.add_argument("Sec-Fetch-Site=cross-site")
capabilities = options.to_capabilities()
capabilities["acceptInsecureCerts"] = True
options.add_argument("user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.82 Safari/537.36")
ser = Service(r"C:\Users\user\Documents\Selenium\chromedriver.exe")
driver = webdriver.Chrome(options=options,service=ser,)
driver.get(url)
So I have a problem that I have been noticing with selenium when I run it headless where some pages don't totally load/render some elements. I don't exactly know what's happening not to load 100%; maybe JS not running?
My code:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from decouple import config
from time import sleep
DEBUG = config('DEBUG')
class DiscordME(object):
def __init__(self):
self.LINUX = config('LINUX', cast=bool)
self.DRIVER_VERSION = config('DRIVER_VERSION')
self.HEADLESS = True
options = Options()
options.add_argument('--no-sandbox')
options.add_argument('--disable-gpu')
options.add_argument('--ignore-certificate-errors')
options.add_argument('--disable-extensions')
options.add_argument('--disable-dev-shm-usage')
if self.HEADLESS:
options.add_argument('--headless')
options.add_argument('--window-size=1920,1200')
if self.LINUX:
self.browser = webdriver.Chrome(executable_path=f'./drivers/chromedriver-{self.DRIVER_VERSION}', options=options)
else:
self.browser = webdriver.Chrome(executable_path=f'.\drivers\chromedriver-{self.DRIVER_VERSION}.exe', options=options)
def get_website(self):
self.browser.get('https://discord.me/login')
WebDriverWait(self.browser, 10).until(
EC.url_changes('https://discord.me/login')
)
print(self.browser.current_url)
print(self.browser.page_source)
#print(self.browser.find_element_by_xpath('//*[#id="app-mount"]/div[2]/div/div[2]/div/div/form/div/div/div[1]/div[3]/div[1]/div/div[2]/input'))
DiscordME().get_website()
In this script, it doesn't load the login inputs when it accesses the discord API login page.
As I can see in the page_source I noticed that the page is not being mounted so that could be the problem.
from selenium import webdriver
from time import sleep
options = webdriver.ChromeOptions()
options.add_argument("--window-size=1920,1080")
options.add_argument("--headless")
options.add_argument("--disable-gpu")
options.add_argument(
"user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.88 Safari/537.36")
browser = webdriver.Chrome(options=options)
some websites uses user-agent to detect whether the browser is in headless mode or not as headless browser uses a different user-agent than normal browser. So explicitly set user agent.
Headless browser detection
Another thing to to consider if you are having trouble loading a website with selenium is the processing power.
I was using a Micro AWS instance with a single CPU which worked for many websites, but when I came to a more complex one it kept intermittently getting 0 elements when conducting a search like find_elements_by_xpath('//a[#href]') while sometimes it would work successfully and find the hyperlinks. I upgraded the instance to one with more CPUs (4, but 2 would probably have been sufficient) and that allowed me to fully load the site and scrape the elements.
I would definitely try the other two solutions posted here first (chrome options or firefox browser), but processing power could be the problem as well.
I Just would like to share my experience on this as solving the issue consumed much of my time trying many options and settings for Chrome webdriver.
The user-agent setting solved the problem for some websites I scraped. but, for some other websites the only solution worked with me was to use FireFox webdriver instead of Chrome as per following :
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
fireFoxOptions = Options()
fireFoxOptions.add_argument("--headless")
fireFoxOptions.add_argument("--window-size=1920,1080")
fireFoxOptions.add_argument('--start-maximized')
fireFoxOptions.add_argument('--disable-gpu')
fireFoxOptions.add_argument('--no-sandbox')
driver = webdriver.Firefox(options=fireFoxOptions,
executable_path=r'C:\[your path to firefox webdriver exe file]\geckodriver.exe')
driver.get('https://discord.me/login')
Use the link here to download latest geckodriver for FireFox, and make sure FireFox browser is already installed in you machine.
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')

Hi guys I'm running some crawling script with Selenium and Python, I want to run the Chrome in headless mode so I set the headless options to true as below
from selenium.webdriver.chrome.options import Options
from selenium import webdriver
options = Options()
options.headless = True
options.add_argument("--start-maximized")
options.add_argument("--window-size=1920,1080")
options.add_argument("--disable-gpu")
options.add_argument("--no-sandbox")
driver = webdriver.Chrome('chromedriver.exe', options=options)
But when running the script, Chrome return the web in mobile version (I've captured screenshot to check the error). Because of this my script cannot run properly
I've try many ways to change it back to desktop website, added arguments like "--window-size=1920,1080", "--start-maximized", etc.. then set browser.maximize_window() and browser.set_window_size(). I also try different chromedriver version but it doesn't work at all
Can anyone help me please? Many thanks.
Yep, I had a very similar issue. The first thing you need to do is manually identify your user agent, check out this site. For example, your user agent could be a long string describing a Safari browser running on macOS that renders web pages using the WebKit engine.
Now go ahead and add in an option to manually set your user agent
options.add_argument("user-agent=User-Agent: your user agent string here")
An example might look like this:
options.add_argument("user-agent=User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/507.06 Safari/507.06")
I've been trying to scrape this page (https://www.riachuelo.com.br/feminino/colecao-feminino) with Selenium but I can´t manage to access the html because it never loads. I've tried using random user agents and other browsers, but the problem persists. Any ideas why is this happening?
Here is the code:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from fake_useragent import UserAgent
URL = "https://www.riachuelo.com.br/feminino/colecao-feminino"
options = Options()
ua = UserAgent()
userAgent = ua.random
options.add_argument(f'user-agent={userAgent}')
driver = webdriver.Chrome(chrome_options=options,executable_path=r"C:\Program Files (x86)\chromedriver.exe")
driver.get(URL)
I executed your usecase to load the webpage at https://www.riachuelo.com.br/feminino/colecao-feminino using Selenium as follows:
from selenium import webdriver
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'C:\WebDrivers\chromedriver.exe')
driver.get('https://www.riachuelo.com.br/feminino/colecao-feminino')
Similarly, as per your observation I have hit the same roadblock that the webpage never loads.:
Analysis
While inspecting the DOM Tree of the webpage you will find that some of the <iframe>, <script> tag refers to the keyword dist. As an example:
src="https://dtbot.directtalk.com.br/1.0/staticbot/dist/js/../index.html#!/?token=c243ce95-db6c-4ab6-9f2b-bf60d69c2d3d&widget=true&top=40&text=Alguma%20d%C3%BAvida%3F&textcolor=ffffff&bgcolor=4E1D3A&from=bottomRigth"
<script id="dtbot-script" src="https://dtbot.directtalk.com.br/1.0/staticbot/dist/js/dtbot.js?token=c243ce95-db6c-4ab6-9f2b-bf60d69c2d3d&widget=true&top=40&text=Alguma%20d%C3%BAvida%3F&textcolor=ffffff&bgcolor=4E1D3A&from=bottomRigth"></script>
