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
I'm trying to use selenium on OSX to open a chrome window with existing cookies so that I can bypass login. When I don't add the argument 'chrome_options=option' to open chrome with my user settings, the driver.get function works fine and it opens a chrome window with no extensions loaded and browses to the url. But when I use the code as shown below, it simply opens chrome (with all extensions loaded) but does not browse to the URL. Am I missing something simple?
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.keys import Keys
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=/Users/me/Library/Application Support/Google/Chrome/")
driver = webdriver.Chrome("./assets/chromedriver",chrome_options=options)
driver.implicitly_wait(30)
driver.maximize_window()
driver.get("https://www.gmail.com/")
I am working on downloading HAR from Chrome for YouTube through Selenium Python Script.
Code Snippet:
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--proxy-server={0}".format(url))
chrome_options.add_argument("--enable-quic")
self.driver = webdriver.Chrome(chromedriver,chrome_options = chrome_options)
self.proxy.new_har(args['url'], options={'captureHeaders': True})
self.driver.get(args['url'])
result = json.dumps(self.proxy.har, ensure_ascii=False)
I want QUIC to be used whenever I download HAR but when I look at the packets through Wireshark Selenium driver is using TCP only. Is there a way to force Chrome Driver to use QUIC? Or Is there an alternate to BMP?
A similar thing has been asked for Firefox in this question How to capture all requests made by page in webdriver? Is there any alternative to Browsermob? and there was a solution with Selenium alone without need of any BMP. So is it possible for Chrome?
Workaround for this problem could be: start Chrome normally (with your default profile or create another profile) and enable quic manually. Then start chromedriver with your profile loaded.
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=/home/user/.config/google-chrome")
driver = webdriver.Chrome(executable_path="/home/user/Downloads/chromedriver", chrome_options=options)
I am trying to submit information in a webpage, but selenium throws this error:
UnexpectedAlertPresentException: Alert Text: This page is asking you
to confirm that you want to leave - data you have entered may not be
saved. ,
>
It's not a leave notification; here is a pic of the notification -
.
If I click in never show this notification again, my action doesn't get saved; is there a way to save it or disable all notifications?
edit: I'm using firefox.
You can disable the browser notifications, using chrome options. Sample code below:
chrome_options = webdriver.ChromeOptions()
prefs = {"profile.default_content_setting_values.notifications" : 2}
chrome_options.add_experimental_option("prefs",prefs)
driver = webdriver.Chrome(chrome_options=chrome_options)
With the latest version of Firefox the above preferences didn't work.
Below is the solution which disable notifications using Firefox object
_browser_profile = webdriver.FirefoxProfile()
_browser_profile.set_preference("dom.webnotifications.enabled", False)
webdriver.Firefox(firefox_profile=_browser_profile)
Disable notifications when using Remote Object:
webdriver.Remote(desired_capabilities=_desired_caps, command_executor=_url, options=_custom_options, browser_profile=_browser_profile)
selenium==3.11.0
Usually with browser settings like this, any changes you make are going to get throws away the next time Selenium starts up a new browser instance.
Are you using a dedicated Firefox profile to run your selenium tests? If so, in that Firefox profile, set this setting to what you want and then close the browser. That should properly save it for its next use. You will need to tell Selenium to use this profile though, thats done by SetCapabilities when you start the driver session.
This will do it:
from selenium.webdriver.firefox.options import Options
options = Options()
options.set_preference("dom.webnotifications.enabled", False)
browser = webdriver.Firefox(firefox_options=options)
For Google Chrome and v3 of Selenium you may receive "DeprecationWarning: use options instead of chrome_options", so you will want to do the following:
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
options = webdriver.ChromeOptions()
options.add_argument('--disable-notifications')
driver = webdriver.Chrome(ChromeDriverManager().install(), options=options)
Note: I am using webdriver-manager, but this also works with specifying the executable_path.
This answer is an improvement on TH Todorov code snippet, based on what is working as of Chrome (Version 80.0.3987.163).
lk = os.path.join(os.getcwd(), "chromedriver",) --> in this line you provide the link to the chromedriver, which you can download from chromedrive link
import os
from selenium import webdriver
lk = os.path.join(os.getcwd(), "chromedriver",)
chrome_options = webdriver.ChromeOptions()
prefs = {"profile.default_content_setting_values.notifications" : 2}
chrome_options.add_experimental_option("prefs",prefs)
driver = webdriver.Chrome(lk, options=chrome_options)
Is it possible to connect selenium to the browser I use normally instead a driver? For normal browsing I am using chrome with several plugins - add block plus, flashblock and several more. I want to try to load a site using this specific configuration. How can I do that?
p.s - I dont want to connect only to an open browser like in this question :
How to connect to an already open browser?
I dont care if I spawn the process using a driver. I just want the full browser configuration - cookies,plugins,fonts etc.
Thanks
First, you need to download the ChromeDriver, then either put the path to the executeable to the PATH environment variable, or pass the path in the executable_path argument:
from selenium import webdriver
driver = webdriver.Chrome(executable_path='/path/to/executeable/chrome/driver')
In order to load extensions, you would need to set ChromeOptions:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = webdriver.ChromeOptions()
options.add_extension('Adblock-Plus_v1.4.1.crx')
driver = webdriver.Chrome(chrome_options=options)
You can also save the chrome user profile you have and load it to the ChromeDriver:
options = webdriver.ChromeOptions()
options.add_argument('--user-data-dir=/path/to/my/profile')
driver = webdriver.Chrome(chrome_options=options)
