Headless Chrome in Alibaba Cloud ECS

Browsing with Headless Chrome in Alibaba Cloud ECS.

Launch a new Instance of Elastic Compute Service (ECS).

Make sure python3 and pip3 are installed on this new instance.

And then run the following commands on terminal:

pip3 install selenium

apt-get install chromium-chromedriver

Save the following python code in file "headlessChrome.py"

import os

from selenium import webdriver

from selenium.webdriver.common.keys import Keys

from selenium.webdriver.chrome.options import Options

from selenium.webdriver.common.by import By

from selenium.webdriver.support.ui import WebDriverWait

from selenium.webdriver.support import expected_conditions as EC

options = Options()

options.add_argument('--headless')

options.add_argument('--start-maximized')

options.add_argument("--start-fullscreen")

options.add_argument("--kiosk");

options.add_argument('--no-sandbox')

options.add_argument('--disable-dev-shm-usage')

options.binary_location = '/usr/bin/chromium-browser'

driver = webdriver.Chrome(executable_path='/usr/bin/chromedriver', options = options)

driver.set_window_size(1024, 800)

driver.maximize_window()

driver.get('https://www.google.com/')

driver.implicitly_wait(2) # seconds

driver.save_screenshot('screenshot.png')

driver.close()

driver.quit()

print('\nDone')

NOTE:

Change the path of chrome's binary if needed, by default it is at:

/usr/bin/chromium-browser

and also the path of chromedrive:

/usr/bin/chromedriver

And then run the above code with python3, on terminal run:

python3 headlessChrome.py

You will get the screenshot of the webpage "www.google.com"

You can now play with this and automate the functioning of browser.

For example, you can input text:

searchPhrase = 'Headless Chrome in Alibaba Cloud'

searchQuery = WebDriverWait(driver,10).until(EC.presence_of_element_located((By.XPATH,"//input[@name='q']")))

searchQuery.send_keys(searchPhrase)

and also click on any element of the web page:

driver.find_element_by_name("btnK").click()
