python 3.x - How to retrieve html source from the web application WindGuru

It's only happen when I use the headless mode.

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument('--headless')

driver = webdriver.Chrome(
    r'C:UsersUsuarioDownloadschromedriver.exe',
    chrome_options=options,
)
driver.get('https://www.windguru.cz/3640')
html = driver.page_source
driver.quit()

# Result
# html = <html xmlns="http://www.w3.org/1999/xhtml"><head></head><body></body></html>

What is happening?

You were almost there. You simply need to induce WebDriverWait for the desired element to be visible and you can use the following solution:

  • Code Block:

    from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

options = webdriver.ChromeOptions()
options.add_argument('--headless')
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:UtilityBrowserDriverschromedriver.exe')
driver.get('https://www.windguru.cz/3640')
WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "#forecasts-page")))
print(driver.page_source)
driver.quit()

  • Console Output:
