Selenium - How to open url in active/current tab in python - python

def get_status(driver):
try:
driver.execute(Command.STATUS)
return "Alive"
except (socket.error, httplib.CannotSendRequest):
return "Dead"
if get_status(driver) == 'Alive':
#using this opens a whole new window but i want to go to another website in same tab.
driver.get('https://www.amazon.in')
else :
driver.get('https://www.google.in')
so basically i want to open a new url in the active tab of chrome/firefox browser. but i failed to find any workaround. i hope you can answer this question.
all tutorials on this redirect me to java function
driver.navigate.to()
which is not working in python.

This code did open a new URL within the same tab.
from selenium import webdriver
from selenium.webdriver.remote.command import Command
import http.client as httplib
import socket
def get_status(driver):
try:
driver.execute(Command.STATUS)
return "Alive"
except (socket.error, httplib.CannotSendRequest):
return "Dead"
driver = webdriver.Chrome(executable_path="path to chromedriver.exe")
driver.maximize_window()
driver.implicitly_wait(20)
driver.get("https://www.youtube.com/")
if get_status(driver) == 'Alive':
# using this opens a whole new window but i want to go to another website in same tab.
driver.get('https://www.amazon.in')
else:
driver.get('https://www.google.in')
driver.quit()

TBSelenium: Tor page closes immediately

I'm trying to use Tor with selenium, which works through the use of tbselenium.
However, when loading an url or clicking a web element, the page immideately closes when finishing the action, instead of remaining open as would be the case when using selenium with chrome.
Any ideas to keep the page open?
import tbselenium.common as cm
from tbselenium.tbdriver import TorBrowserDriver
from tbselenium.utils import launch_tbb_tor_with_stem
tbb_dir = "C:\\pathto\\Tor Browser\\"
tor_process = launch_tbb_tor_with_stem(tbb_path=tbb_dir)
for i in range(1):
with TorBrowserDriver(tbb_dir, tor_cfg=cm.USE_STEM) as driver:
driver.load_url("http://hln.be",3,wait_for_page_body=True)
#driver.get('https://google.be')
try:
policypage=driver.find_element_by_xpath("//a[contains(#href,'members/join')]")
policypage.click()
usern=driver.find_element_by_xpath("//input[contains(#id,'user_member_username')]")
usern.send_keys('Tryout')
except:
print('different look')
As Furas said, use the standard driver declaration.

selenium works on local and not on azure server

I am trying to get video url from links on this page. Video link could be seen on https://in.news.yahoo.com/video/jaguar-fighter-aircraft-crashes-near-084300217.html . (Open in Chrome)
For that I wrote chrome web driver related code as below :
from bs4 import BeautifulSoup
from selenium import webdriver
from pyvirtualdisplay import Display
chromedriver = '/usr/local/bin/chromedriver'
os.environ['webdriver.chrome.driver'] = chromedriver
display = Display(visible=0, size=(800,600))
display.start()
driver = webdriver.Chrome(chromedriver)
driver.get('https://in.news.yahoo.com/video/jaguar-fighter-aircraft-crashes-near-084300217.html')
try:
element = WebDriverWait(driver, 20).until(lambda driver: driver.find_elements_by_class_name('yvp-main'))
self.yahoo_video_trend = []
for s in driver.find_elements_by_class_name('yvp-main'):
print "Processing link - ", item['link']
trend = item
print item['description']
trend['video_link'] = s.find_element_by_tag_name('video').get_attribute('src')
print
print s.find_element_by_tag_name('video').get_attribute('src')
self.yahoo_video_trend.append(trend)
except:
return
This works fine on my local system but when I run on my azure server it does not give any result at s.find_element_by_tag_name('video').get_attribute('src')
I have installed chrome on my azureserver.
Update :
Please see, requests and Beautifulsoup I already tried, but as yahoo loads html content dynamically from json, I could not get it using them.
And yeah azure server is simple linux system with command line access. Not any application.
I tried to reproduce your issue using you code. However, I found there was no tag named video in that page('https://in.news.yahoo.com/video/jaguar-fighter-aircraft-crashes-near-084300217.html')(using IE and Chrome to test).
I used the developer Tool to check the HTML code, like this picture:
It seems that this page used the flash player to play video,not HTML5 video control.
For this reason, I suggest that you can check your code whether used the rightly tag name.
Any concerns, please feel free to let me know.
We tried to reproduce the error on our side. I was not able to get chrome driver to work, but I did try the firefox driver and it worked fine. It was able to load the page and get the link via the URL.
Can you change your code to print the exception and send it to us, to see where the script is failing?
Change your code:
except:
return
try
do
except Exception,e: print str(e)
Send us the exception, so we can take a look.

How do I switch to the active tab in Selenium?

We developed a Chrome extension, and I want to test our extension with Selenium. I created a test, but the problem is that our extension opens a new tab when it's installed, and I think I get an exception from the other tab. Is it possible to switch to the active tab I'm testing? Or another option is to start with the extension disabled, then login to our website and only then enable the extension. Is it possible? Here is my code:
def login_to_webapp(self):
self.driver.get(url='http://example.com/logout')
self.driver.maximize_window()
self.assertEqual(first="Web Editor", second=self.driver.title)
action = webdriver.ActionChains(driver=self.driver)
action.move_to_element(to_element=self.driver.find_element_by_xpath(xpath="//div[#id='header_floater']/div[#class='header_menu']/button[#class='btn_header signature_menu'][text()='My signature']"))
action.perform()
self.driver.find_element_by_xpath(xpath="//ul[#id='signature_menu_downlist'][#class='menu_downlist']/li[text()='Log In']").click()
self.driver.find_element_by_xpath(xpath="//form[#id='atho-form']/div[#class='input']/input[#name='useremail']").send_keys("[email]")
self.driver.find_element_by_xpath(xpath="//form[#id='atho-form']/div[#class='input']/input[#name='password']").send_keys("[password]")
self.driver.find_element_by_xpath(xpath="//form[#id='atho-form']/button[#type='submit'][#class='atho-button signin_button'][text()='Sign in']").click()
The test fails with ElementNotVisibleException: Message: element not visible, because in the new tab (opened by the extension) "Log In" is not visible (I think the new tab is opened only after the command self.driver.get(url='http://example.com/logout')).
Update: I found out that the exception is not related to the extra tab, it's from our website. But I closed the extra tab with this code, according to #aberna's answer:
def close_last_tab(self):
if (len(self.driver.window_handles) == 2):
self.driver.switch_to.window(window_name=self.driver.window_handles[-1])
self.driver.close()
self.driver.switch_to.window(window_name=self.driver.window_handles[0])
After closing the extra tab, I can see my tab in the video.
This actually worked for me in 3.x:
driver.switch_to.window(driver.window_handles[1])
window handles are appended, so this selects the second tab in the list
to continue with first tab:
driver.switch_to.window(driver.window_handles[0])
Some possible approaches:
1 - Switch between the tabs using the send_keys (CONTROL + TAB)
self.driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + Keys.TAB)
2 - Switch between the tabs using the using ActionsChains (CONTROL+TAB)
actions = ActionChains(self.driver)
actions.key_down(Keys.CONTROL).key_down(Keys.TAB).key_up(Keys.TAB).key_up(Keys.CONTROL).perform()
3 - Another approach could make usage of the Selenium methods to check current window and move to another one:
You can use
driver.window_handles
to find a list of window handles and after try to switch using the following methods.
- driver.switch_to.active_element
- driver.switch_to.default_content
- driver.switch_to.window
For example, to switch to the last opened tab, you can do:
driver.switch_to.window(driver.window_handles[-1])
The accepted answer didn't work for me.
To open a new tab and have selenium switch to it, I used:
driver.execute_script('''window.open("https://some.site/", "_blank");''')
sleep(1) # you can also try without it, just playing safe
driver.switch_to.window(driver.window_handles[-1]) # last opened tab handle
# driver.switch_to_window(driver.window_handles[-1]) # for older versions
if you need to switch back to the main tab, use:
driver.switch_to.window(driver.window_handles[0])
Summary:
The window_handles contains a list of the handles of opened tabs, use it as argument in switch_to.window() to switch between tabs.
Pressing ctrl+t or choosing window_handles[0] assumes that you only have one tab open when you start.
If you have multiple tabs open then it could become unreliable.
This is what I do:
old_tabs=self.driver.window_handles
#Perform action that opens new window here
new_tabs=self.driver.window_handles
for tab in new_tabs:
if tab in old tabs:
pass
else:
new_tab=tab
driver.switch_to.window(new_tab)
This is something that would positively identify the new tab before switching to it and sets the active window to the desired new tab.
Just telling the browser to send ctrl+tab does not work because it doesn't tell the webdriver to actually switch to the new tab.
if you want to close only active tab and need to keep the browser window open, you can make use of switch_to.window method which has the input parameter as window handle-id. Following example shows how to achieve this automation:
from selenium import webdriver
import time
driver = webdriver.Firefox()
driver.get('https://www.google.com')
driver.execute_script("window.open('');")
time.sleep(5)
driver.switch_to.window(driver.window_handles[1])
driver.get("https://facebook.com")
time.sleep(5)
driver.close()
time.sleep(5)
driver.switch_to.window(driver.window_handles[0])
driver.get("https://www.yahoo.com")
time.sleep(5)
#driver.close()
The tip from the user "aberna" worked for me the following way:
First I got a list of the tabs:
tab_list = driver.window_handles
Then I selectet the tab:
driver.switch_to.window(test[1])
Going back to previous tab:
driver.switch_to.window(test[0])
TLDR: there is a workaround solution, with some limitations.
I am working with the already opened browser, as shown here. The problem is that every time I launch the script, selenium internally selects a random tab. The official documentation says:
Clicking a link which opens in a new window will focus the new window
or tab on screen, but WebDriver will not know which window the
Operating System considers active.
It sounds very strange to me. Because is not that the first task of selenium to handle and automate browser interaction? More of that, switching to any tab with driver.switch_to.window(...) actually will switch the active tab in gui. Seems that it is a bug. At the moment of writing the python-selenium version is 4.1.0.
Let's look which approaches could we use.
Using selenium window_handles[0] approach
The approach from the answer above is not reliable. It does not always work. For example when you switch between different tabs, chromium/vivaldi may start returning not a current tab.
print("Current driver tab:", driver.title) # <- the random tab title
driver.switch_to.window(chromium_driver.window_handles[0])
print("Current driver tab:", driver.title) # <-- the currently opened tab title. But not always reliable.
So skip this method.
Using remote debugging approach
Provides nothing additional to what is in selenium driver from previous approach.
Getting the list of tabs via the remote debugging protocol like
r = requests.get("http://127.0.0.1:9222/json")
j = r.json()
found_tab = False
for el in j:
if el["type"] == "page": # Do this check, because if that is background-page, it represents one of installed extensions
found_tab = el
break
if not found_tab:
print("Could not find tab", file=sys.stderr)
real_opened_tab_handle = "CDwindow-" + found_tab["id"]
driver.switch_to(real_opened_tab_handle)
actually returns the same as what is in driver.window_handles. So also skip this method.
Workaround solution for X11
from wmctrl import Window
all_x11_windows = Window.list()
chromium_windows = [ el for el in all_x11_windows if el.wm_class == 'chromium.Chromium' ]
if len(chromium_windows) != 1:
print("unexpected numbner of chromium windows")
exit(1)
real_active_tab_name = chromium_windows[0].wm_name.rstrip(" – Chromium")
chrome_options = Options()
chrome_options.add_experimental_option("debuggerAddress", "127.0.0.1:9222")
# https://stackoverflow.com/a/70088095/7869636 - Selenium connect to existing browser.
# Need to start chromium as: chromium --remote-debugging-port=9222
driver = webdriver.Chrome(service=Service(ChromeDriverManager(chrome_type=ChromeType.CHROMIUM).install()), options=chrome_options)
tabs = driver.window_handles
found_active_tab = False
for tab in tabs:
driver.switch_to.window(tab)
if driver.title != real_active_tab_name:
continue
else:
found_active_tab = True
break
if not found_active_tab:
print("Cannot switch to needed tab, something went wrong")
exit(1)
else:
print("Successfully switched to opened tab")
print("Working with tab called:", driver.title)
The idea is to get the window title from wmctrl, which will let you know the active tab name.
Workaround solution for Wayland
Previous solution has a limitation, wmctrl only works with x11 windows.
I currently found out how to get the title of a window at which you click.
print("Please click on the browser window")
opened_tab = subprocess.run("qdbus org.kde.KWin /KWin queryWindowInfo | grep caption", shell=True, capture_output=True).stdout.decode("utf-8")
opened_tab_title = opened_tab.rstrip(" - Vivaldi\n").lstrip("caption: ")
Then the script from the previous solution could be used.
The solution could be improved using kwin window list query on wayland. I would be glad if somebody helps to improve this. Unfortunately, I do not know currently how to get list of wayland windows.
Here is the full script.

Found a way using ahk library. Very easy for us non-programmers that need to solve this problem. used Python 3.7.3
Install ahk with. pip install ahk
import ahk
from ahk import AHK
import selenium
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = webdriver.ChromeOptions()
options.add_experimental_option("excludeSwitches", ['enable-automation']); #to disable infobar about chrome controlled by automation.
chrome_options.add_argument('--start-maximized')
chromeDriver = webdriver.Chrome('C:\\new_software\\chromedriver.exe', chrome_options = options) #specify your chromedriver location
chromeDriver.get('https://www.autohotkey.com/')#launch a tab
#launch some other random tabs for testing.
chromeDriver.execute_script("window.open('https://developers.google.com/edu/python/introduction', 'tab2');")
chromeDriver.execute_script("window.open('https://www.facebook.com/', 'tab3');")
chromeDriver.execute_script("window.open('https://developer.mozilla.org/en-US/docs/Web/API/Window/open', 'tab4');"`)
seleniumwindow = ahk.active_window #as soon as you open you Selenium session, get a handle of the window frame with AHK.
seleniumwindow.activate() #will activate whatever tab you have active in the Selenium browser as AHK is activating the window frame
#To activate specific tabs I would use chromeDriver.switchTo()
#chromeDriver.switch_to_window(chromeDriver.window_handles[-1]) This takes you to the last opened tab in Selenium and chromeDriver.switch_to_window(chromeDriver.window_handles[1])to the second tab, etc..

Python - Selenium - Print Webpage

How do I print a webpage using selenium please.
import time
from selenium import webdriver
# Initialise the webdriver
chromeOps=webdriver.ChromeOptions()
chromeOps._binary_location = "C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe"
chromeOps._arguments = ["--enable-internal-flash"]
browser = webdriver.Chrome("C:\\Program Files\\Google\\Chrome\\Application\\chromedriver.exe", port=4445, chrome_options=chromeOps)
time.sleep(3)
# Login to Webpage
browser.get('www.webpage.com')
Note: I am using the, at present, current version of Google Chrome: Version 32.0.1700.107 m
While it's not directly printing the webpage, it is easy to take a screenshot of the entire current page:
browser.save_screenshot("screenshot.png")
Then the image can be printed using any image printing library. I haven't personally used any such library so I can't necessarily vouch for it, but a quick search turned up win32print which looks promising.
The key "trick" is that we can execute JavaScript in the selenium browser window using the "execute_script" method of the selenium webdriver, and if you execute the JavaScript command "window.print();" it will activate the browsers print function.
Now, getting it to work elegantly requires setting a few preferences to print silently, remove print progress reporting, etc. Here is a small but functional example that loads up and prints whatever website you put in the last line (where 'http://www.cnn.com/' is now):
import time
from selenium import webdriver
import os
class printing_browser(object):
def __init__(self):
self.profile = webdriver.FirefoxProfile()
self.profile.set_preference("services.sync.prefs.sync.browser.download.manager.showWhenStarting", False)
self.profile.set_preference("pdfjs.disabled", True)
self.profile.set_preference("print.always_print_silent", True)
self.profile.set_preference("print.show_print_progress", False)
self.profile.set_preference("browser.download.show_plugins_in_list",False)
self.driver = webdriver.Firefox(self.profile)
time.sleep(5)
def get_page_and_print(self, page):
self.driver.get(page)
time.sleep(5)
self.driver.execute_script("window.print();")
if __name__ == "__main__":
browser_that_prints = printing_browser()
browser_that_prints.get_page_and_print('http://www.cnn.com/')
The key command you were probably missing was "self.driver.execute_script("window.print();")" but one needs some of that setup in init to make it run smooth so I thought I'd give a fuller example. I think the trick alone is in a comment above so some credit should go there too.

How can I download a file on a click event using selenium?

I am working on python and selenium. I want to download file from clicking event using selenium. I wrote following code.
from selenium import webdriver
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.common.keys import Keys
browser = webdriver.Firefox()
browser.get("http://www.drugcite.com/?q=ACTIMMUNE")
browser.close()
I want to download both files from links with name "Export Data" from given url. How can I achieve it as it works with click event only?
Find the link using find_element(s)_by_*, then call click method.
from selenium import webdriver
# To prevent download dialog
profile = webdriver.FirefoxProfile()
profile.set_preference('browser.download.folderList', 2) # custom location
profile.set_preference('browser.download.manager.showWhenStarting', False)
profile.set_preference('browser.download.dir', '/tmp')
profile.set_preference('browser.helperApps.neverAsk.saveToDisk', 'text/csv')
browser = webdriver.Firefox(profile)
browser.get("http://www.drugcite.com/?q=ACTIMMUNE")
browser.find_element_by_id('exportpt').click()
browser.find_element_by_id('exporthlgt').click()
Added profile manipulation code to prevent download dialog.
I'll admit this solution is a little more "hacky" than the Firefox Profile saveToDisk alternative, but it works across both Chrome and Firefox, and doesn't rely on a browser-specific feature which could change at any time. And if nothing else, maybe this will give someone a little different perspective on how to solve future challenges.
Prerequisites: Ensure you have selenium and pyvirtualdisplay installed...
Python 2: sudo pip install selenium pyvirtualdisplay
Python 3: sudo pip3 install selenium pyvirtualdisplay
The Magic
import pyvirtualdisplay
import selenium
import selenium.webdriver
import time
import base64
import json
root_url = 'https://www.google.com'
download_url = 'https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png'
print('Opening virtual display')
display = pyvirtualdisplay.Display(visible=0, size=(1280, 1024,))
display.start()
print('\tDone')
print('Opening web browser')
driver = selenium.webdriver.Firefox()
#driver = selenium.webdriver.Chrome() # Alternately, give Chrome a try
print('\tDone')
print('Retrieving initial web page')
driver.get(root_url)
print('\tDone')
print('Injecting retrieval code into web page')
driver.execute_script("""
window.file_contents = null;
var xhr = new XMLHttpRequest();
xhr.responseType = 'blob';
xhr.onload = function() {
var reader = new FileReader();
reader.onloadend = function() {
window.file_contents = reader.result;
};
reader.readAsDataURL(xhr.response);
};
xhr.open('GET', %(download_url)s);
xhr.send();
""".replace('\r\n', ' ').replace('\r', ' ').replace('\n', ' ') % {
'download_url': json.dumps(download_url),
})
print('Looping until file is retrieved')
downloaded_file = None
while downloaded_file is None:
# Returns the file retrieved base64 encoded (perfect for downloading binary)
downloaded_file = driver.execute_script('return (window.file_contents !== null ? window.file_contents.split(\',\')[1] : null);')
print(downloaded_file)
if not downloaded_file:
print('\tNot downloaded, waiting...')
time.sleep(0.5)
print('\tDone')
print('Writing file to disk')
fp = open('google-logo.png', 'wb')
fp.write(base64.b64decode(downloaded_file))
fp.close()
print('\tDone')
driver.close() # close web browser, or it'll persist after python exits.
display.popen.kill() # close virtual display, or it'll persist after python exits.
Explaination
We first load a URL on the domain we're targeting a file download from. This allows us to perform an AJAX request on that domain, without running into cross site scripting issues.
Next, we're injecting some javascript into the DOM which fires off an AJAX request. Once the AJAX request returns a response, we take the response and load it into a FileReader object. From there we can extract the base64 encoded content of the file by calling readAsDataUrl(). We're then taking the base64 encoded content and appending it to window, a gobally accessible variable.
Finally, because the AJAX request is asynchronous, we enter a Python while loop waiting for the content to be appended to the window. Once it's appended, we decode the base64 content retrieved from the window and save it to a file.
This solution should work across all modern browsers supported by Selenium, and works whether text or binary, and across all mime types.
Alternate Approach
While I haven't tested this, Selenium does afford you the ability to wait until an element is present in the DOM. Rather than looping until a globally accessible variable is populated, you could create an element with a particular ID in the DOM and use the binding of that element as the trigger to retrieve the downloaded file.
In chrome what I do is downloading the files by clicking on the links, then I open chrome://downloads page and then retrieve the downloaded files list from shadow DOM like this:
docs = document
.querySelector('downloads-manager')
.shadowRoot.querySelector('#downloads-list')
.getElementsByTagName('downloads-item')
This solution is restrained to chrome, the data also contains information like file path and download date. (note this code is from JS, may not be the correct python syntax)
Here is the full working code. You can use web scraping to enter the username password and other field. For getting the field names appearing on the webpage, use inspect element. Element name(Username,Password or Click Button) can be entered through class or name.
from selenium import webdriver
# Using Chrome to access web
options = webdriver.ChromeOptions()
options.add_argument("download.default_directory=C:/Test") # Set the download Path
driver = webdriver.Chrome(options=options)
# Open the website
try:
driver.get('xxxx') # Your Website Address
password_box = driver.find_element_by_name('password')
password_box.send_keys('xxxx') #Password
download_button = driver.find_element_by_class_name('link_w_pass')
download_button.click()
driver.quit()
except:
driver.quit()
print("Faulty URL")
