Python Selenium Headless download

Question

I'm trying to download a file with selenium. I've searched everything.

At How to control the download of files with Selenium Python bindings in Chrome some people told that it worked. But it didn't worked for me! Maybe I miss something? The only things differentlly is that my page autostarted download the csv file.

After studying the chrome codes I added:

        "safebrowsing_for_trusted_sources_enabled": False

But still id didn't worked.

options = Options()
options.add_argument("--disable-notifications")
options.add_argument('--no-sandbox')
options.add_experimental_option("prefs", {
    "download.default_directory": "C:\\Users\\claudiu.ivanescu\\Downloads",
    "download.prompt_for_download": False,
    "download.directory_upgrade": True,
    "safebrowsing_for_trusted_sources_enabled": False
})
options.add_argument('--disable-gpu')
options.add_argument('--disable-software-rasterizer')
options.add_argument('--headless')

Thank for support

Answer 1

If anybody interested, after 2 days of search :). I manage to make it works!

I found the answer the bug tracking in this comment: https://bugs.chromium.org/p/chromium/issues/detail?id=696481#c86

The code I used is:

def enable_download_headless(browser,download_dir):
    browser.command_executor._commands["send_command"] = ("POST", '/session/$sessionId/chromium/send_command')
    params = {'cmd':'Page.setDownloadBehavior', 'params': {'behavior': 'allow', 'downloadPath': download_dir}}
    browser.execute("send_command", params)

if __name__ == '__main__':
    options = Options()
    options.add_argument("--disable-notifications")
    options.add_argument('--no-sandbox')
    options.add_argument('--verbose')
    options.add_experimental_option("prefs", {
        "download.default_directory": "C:\\tmp",
        "download.prompt_for_download": False,
        "download.directory_upgrade": True,
        "safebrowsing_for_trusted_sources_enabled": False,
        "safebrowsing.enabled": False
    })
    options.add_argument('--disable-gpu')
    options.add_argument('--disable-software-rasterizer')
    options.add_argument('--headless')
    driver_path = "C:\\Users\\tmp\\chromedriver.exe"
    driver = webdriver.Chrome(driver_path, chrome_options=options)
    enable_download_headless(driver, "C:/tmp")
    driver.get(url)

Maybe will be some use to others in the future... Probably is a lot of useless things inside, but didn't have time yet to change :).
