How to use chrome webdriver in selenium to download files in python?

Try this. Executed on windows

(How to control the download of files with Selenium Python bindings in Chrome)

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_experimental_option("prefs", {
  "download.default_directory": r"C:\Users\xxx\downloads\Test",
  "download.prompt_for_download": False,
  "download.directory_upgrade": True,
  "safebrowsing.enabled": True
})

I think that the easiest way to save arbitrary file (i.e. image) using WebDriver is to execute JavaScript which will save file. No configuration required at all!

I use this library FileSaver.js to save a file with desired name with ease.

from selenium import webdriver
import requests

FILE_SAVER_MIN_JS_URL = "https://raw.githubusercontent.com/eligrey/FileSaver.js/master/dist/FileSaver.min.js"

file_saver_min_js = requests.get(FILE_SAVER_MIN_JS_URL).content

chrome_options = webdriver.ChromeOptions()
driver = webdriver.Chrome('/usr/local/bin/chromedriver', options=chrome_options)

# Execute FileSaver.js in page's context
driver.execute_script(file_saver_min_js)

# Now you can use saveAs() function
download_script = f'''
    return fetch('https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-logo.svg?v=a010291124bf',
        {{
            "credentials": "same-origin",
            "headers": {{"accept":"image/webp,image/apng,image/*,*/*;q=0.8","accept-language":"en-US,en;q=0.9"}},
            "referrerPolicy": "no-referrer-when-downgrade",
            "body": null,
            "method": "GET",
            "mode": "cors"
        }}
    ).then(resp => {{
        return resp.blob();
    }}).then(blob => {{
        saveAs(blob, 'stackoverflow_logo.svg');
    }});
    '''

driver.execute_script(download_script)
# Done! Your browser has saved an SVG image!
