Chrome headless file download from Selenium in Python

Question

In silent mode, Chrome prohibits the download of files by default.

However, they recently added the DevTools parameter to enable this behavior:

Using Selenium with ChromeDriver in Python, how to allow file downloads?

Answer 1

For those who are still watching, Here's how I did it:

def enable_download_in_headless_chrome( driver, download_dir):
    #add missing support for chrome "send_command"  to selenium webdriver
    driver.command_executor._commands["send_command"] = ("POST", '/session/$sessionId/chromium/send_command')

    params = {'cmd': 'Page.setDownloadBehavior', 'params': {'behavior': 'allow', 'downloadPath': download_dir}}
    driver.execute("send_command", params)
