I have a python code that surfs multiple pages on the internet and downloads files, using selenium.
The problem is that after the first file downloaded, the chrome driver asks to allow multiple downloads, which leads to continue surfing without actually downloading any further files.
How can I prevent that from happening? using selenium or editing the chrome driver
You can define below options :
chrome_options = webdriver.ChromeOptions()
prefs = {'profile.default_content_setting_values.automatic_downloads': 1}
chrome_options.add_experimental_option("prefs", prefs)
driver = webdriver.Chrome(options = chrome_options)
So whenever I try to use my Chrome settings (the settings I use in the default browser) by adding
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=C:\Users\... (my webdriver path)")
driver = webdriver.Chrome(executable_path="myPath", options=options)
it shows me the error code
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes n 16-17: truncated \UXXXXXXXX escape
in my bash. I don't know what that means and I'd be happy for any kind of help I can get. Thanks in advance!
The accepted answer is wrong. This is the official and correct way to do it:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = webdriver.ChromeOptions()
options.add_argument(r"--user-data-dir=C:\path\to\chrome\user\data") #e.g. C:\Users\You\AppData\Local\Google\Chrome\User Data
options.add_argument(r'--profile-directory=YourProfileDir') #e.g. Profile 3
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', chrome_options=options)
driver.get("https://www.google.co.in")
To find the profile folder on Windows right-click the desktop shortcut of the Chrome profile you want to use and go to properties -> shortcut and you will find it in the "target" text box.
To get the path, follow the steps below.
In the search bar type the following and press enter
This will then show all the metadata. There find the path to the profile
As per your question and your code trials if you want to open a Chrome Browsing Session here are the following options:
To use the default Chrome Profile:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=C:\\Users\\AtechM_03\\AppData\\Local\\Google\\Chrome\\User Data\\Default")
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', chrome_options=options)
driver.get("https://www.google.co.in")
Note: Your default chrome profile would contain a lot of bookmarks, extensions, theme, cookies etc. Selenium may fail to load it. So as per the best practices create a new chrome profile for your #Test and store/save/configure within the profile the required data.
To use the customized Chrome Profile:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("user-data-dir=C:\\Users\\AtechM_03\\AppData\\Local\\Google\\Chrome\\User Data\\Profile 2")
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', chrome_options=options)
driver.get("https://www.google.co.in")
Here you will find a detailed discussion on How to open a Chrome Profile through Python
This is how I managed to use EXISTING CHROME PROFILE in php selenium webdriver.
Profile 6 is NOT my default profile. I dont know how to run default profile. It is IMPORTANT not to add -- before chrome option arguments! All other variants of options didnt work!
<?php
//...
$chromeOptions = new ChromeOptions();
$chromeOptions->addArguments([
'user-data-dir=C:/Users/MyUser/AppData/Local/Google/Chrome/User Data',
'profile-directory=Profile 6'
]);
$host = 'http://localhost:4444/wd/hub'; // this is the default
$capabilities = DesiredCapabilities::chrome();
$capabilities->setCapability(ChromeOptions::CAPABILITY, $chromeOptions);
$driver = RemoteWebDriver::create($host, $capabilities, 100000, 100000);
To get name of your chrome profile, go to chrome://settings/manageProfile, click on profile icon, click "Show profile shortcut on my desktop". After that right click on desktop profile icon and go to properties, here you will see something like "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Profile 6".
Also I recommend you to close all chrome instances before running this code. Also maybe you need to TURN OFF chrome settings > advanced > system > "Continue running background apps when Google Chrome is closed".
None of the given answers were working for me so I researched a bit and now the working code is for is this one. I copied the user dir folder from Profile Path from chrome://version/ and made another argument for the profile as shown below:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = webdriver.ChromeOptions()
options.add_argument('user-data-dir=C:\\Users\\gupta\\AppData\\Local\\Google\\Chrome\\User Data')
options.add_argument('profile-directory=Profile 1')
driver = webdriver.Chrome(executable_path=r'C:\Program Files (x86)\chromedriver.exe', options=options)
driver.get('https://google.com')
Are you sure you are meant to be putting in the webdriver path in the user-data-dir argument? That's usually where you put your chrome profile e.g. "C:\Users\yourusername\AppData\Local\Google\Chrome\User Data\Profile 1\". Also you will need to use either double backslashes or forward slashes in your directory path (both work). You can test if your path works by using the os library
e.g.
import os
os.list("C:\\Users\\yourusername\\AppData\\Local\\Google\\Chrome\\User Data\\Profile 1")
will give you the directory listing.
I might also add that occasionally if you manage to crash chrome while running webdriver with a nominated user profile, that it seems to record the crash in the profile and the next time you open chrome, you get the Chrome prompt to restore pages after it exited abnormally. For me personally this had been a bit of headache to deal with and I no longer use a user profile with chromedriver because of it. I could not find a way around it. Other people have reported it here, but none of their solutions seemed to work for me, or were not suitable for my test cases. https://superuser.com/questions/237608/how-to-hide-chrome-warning-after-crash
If you don't nominate a user profile it seems to create a new (blank) temporary one each time it runs
Make sure you've got the path to the profile right, and that you double escape backslashes in said path.
For example, typically the default profile on windows is located at:
"C:\\Users\\user\\AppData\\Local\\Google\\Chrome\\User Data\\Default"
I managed to launch my chrome profile using these arguments:
ChromeOptions options = new ChromeOptions();
options.addArguments("--user-data-dir=C:\\Users\\user\\AppData\\Local\\Google\\Chrome\\User Data");
options.addArguments("--profile-directory=Profile 2");
WebDriver driver = new ChromeDriver(options);
You can find out more about the web driver here
You simply have to replace the '\' to '/' in your paths and that'll resolve it.
Get profile name by navigating to chrome://version from your chrome browser (You'll see Profile Path, but you only want the profile name from it (e.g. Profile 1)
Close out all Chrome sessions using the profile you want to use. (or else you will get the following error: InvalidArgumentException)
Now make sure you have the code below (Make sure you replace UserFolder with the name of your userfolder.
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=C:\\Users\\EnterYourUserFolder\\AppData\\Local\\Google\\Chrome\\User Data") #leave out the profile
options.add_argument("profile-directory=Profile 1") #enter profile here
driver = webdriver.Chrome(executable_path="C:\\chromedriver.exe", chrome_options=options)
this worked for me 100% and it showed up my selected profile.
import os
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
# path of your chrome webdriver
dir_path = os.getcwd()
user_profile_path = os.environ[ 'USERPROFILE' ]
#if "frtkpr" which is ll be your custom profile does not exist it will be created.
option.add_argument( "user-data-dir=" + user_profile_path + "/AppData/Local/Google/Chrome/User Data/frtkpr" )
driver = webdriver.Chrome( dir_path + "/chromedriver.exe",chrome_options=option )
baseUrl = "https://www.facebook.com/"
driver.maximize_window()
driver.get( baseUrl )
During the test, a file (.html) will be downloaded from the web application & I have to verify that file by opening it on the browser. In the non-headless mode, my test is working fine. But whenever I'm going to headless mode, that file is not getting downloaded to the download path (i.e. pointed in the "user.dir"). My chrome driver version is 2.44.609538 & selenium version is 3.14.
Apparently this could help you
Shawn Button post the answer related with it.
Downloading with chrome headless and selenium
Are you running the test from the command line?
Because, according to an answer to this question and this, when you run it via command line, your user.dir corresponds to your global user directory (C:\users\username).
This worked for our ruby implementation:
Capybara.register_driver :scrapping_driver do |app|
options = Selenium::WebDriver::Chrome::Options.new
options.add_argument('--headless')
options.add_argument('--disable-popup-blocking')
options.add_argument('--disable-gpu')
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
options.add_argument('--window-size=1366,2000')
options.add_preference(:download, directory_upgrade: true,
prompt_for_download: false,
default_directory: "#{Rails.root}/")
options.add_preference(:browser, set_download_behavior: { behavior: 'allow' })
Selenium::WebDriver::Service.driver_path = Webdrivers::Chromedriver.driver_path
driver = Capybara::Selenium::Driver.new(app, browser: :chrome, options: options)
end
Pay attention at download behaviour
I met same situation.
Headless mode is very faster. So your code might be implemented to detect download(DL).
Solution.
(Current your process?) .click for DL -> Detecting download file generation.
(My solution) Detecting download file generation -> .click for DL.
I implemented the above mechanism using callback function.
I have been searching on the internet using Selenium (Java) interacting with Google Chrome Extension but have not been able to find an answer.
First Question
Is there a way to launch the chrome extension since Selenium only interact with WebView but not on the chrome extensions button in the browser ?
I try this method
"chrome-extension://id/index.html" but the extension did not launch as expected. I like find if there is another way to launch a chrome extension through selenium
Second Question
I am trying to click on the elements in a chrome extension with Selenium webdriver. How do I do it ? I tried the driver.CurrentWindowHandle , but it does not detect the chrome extension.
Thanks
Below is the solution with pyautogui (similar to autoit in java - so you can extend the same solution for java also).
Pre-Condition:
save the extension image in the project folder (I saved it under "autogui_ref_snaps" folder in my example with "capture_full_screenshot.png" name
Python:
Imports needed
from selenium import webdriver
from selenium.webdriver import ChromeOptions
from Common_Methods.GenericMethods import *
import pyautogui #<== need this to click on extension
Script:
options = ChromeOptions()
options.add_argument("--load-extension=" + r"C:\Users\supputuri\AppData\Local\Google\Chrome\User Data\Default\Extensions\fdpohaocaechififmbbbbbknoalclacl\5.1_0") #<== loading unpacked extension
driver = webdriver.Chrome(
executable_path=os.path.join(chrome_options=options)
url = "https://google.com/"
driver.get(url)
# get the extension box
extn = pyautogui.locateOnScreen(os.path.join(GenericMethods.get_full_path_to_folder('autogui_ref_snaps') + "/capture_full_screenshot.png"))
# click on extension
pyautogui.click(x=extn[0],y=extn[1],clicks=1,interval=0.0,button="left")
If you are loading an extension and it's not available in incognito mode then follow my answer in here to enable it.
Try to click on extension with this JsExecutor method:
driver.execute_script("window.postMessage('clicked_browser_action', '*')")
I'm building a webscraping app and I'm using Selenium with a Firefox driver to open my pages. Whenever it opens a link that leads to a download, my app stalls and hangs on the link for eternity.
I've tried looking for a solution, but they never mention disabling downloads. They only talk about enabling them, changing the download directory,...
Would it be possible to detect that the link is a download link and just skip it, or maybe to skip the link whenever it opens?
I had a slightly different problem and I solved it by changing Firefox capabilities.
Open about:config in Firefox to see list of them. Then you can pass them to webdriver through desired_capabilities.
caps = {'acceptInsecureCerts': True,
'browserName': 'firefox',
'marionette': True,
'moz:firefoxOptions': {
'args': ['--no-remote'],
'prefs': {
'browser.safebrowsing.downloads.enabled': False
}
},
driver = webdriver.Remote([...]
desired_capabilities=caps)
