How do I automatically download files from a pop up dialog using selenium-python

Question

I am trying to automatically download files from a pop up dialog using selenium-python.

The firefox popups look like this

I want to simulate clicking "OK"

I found this answer How do I trap a popup in Selenium 2 python which sent me to the docs https://selenium-python.readthedocs.org/en/latest/navigating.html?highlight=popup#popup-dialogs

I've tried this

    alert = driver.switch_to_alert()
    #alert.send_keys(Keys.RETURN) #No alert is present

and this

    alert = driver.switch_to_alert()
    alert.accept()  #no alert is present

If I run pprint.pprint(driver.window_handles) it prints only a single GUID -- showing that only one window is present.

So if no alert is present and there is only one window -- how do I download these files?

Answer 1

In python, but this will work in Java as well because the firefox preferences are a javascript:

profile.set_preference("browser.download.panel.shown", False)
profile.set_preference("browser.helperApps.neverAsk.openFile","text/csv,application/vnd.ms-excel")
profile.set_preference("browser.helperApps.neverAsk.saveToDisk", "text/csv,application/vnd.ms-excel")
profile.set_preference("browser.download.folderList", 2);
profile.set_preference("browser.download.dir", "c:\\firefox_downloads\\")
browser = webdriver.WebDriver(firefox_profile=profile)

this works for CSV files, modify it for whatever filetype you are downloading.

Answer 2

Based on Amey's answer 1) and of course Yi Zeng's blog (in ruby) quoting Selenium itself doesn’t interact with system-level dialogs like this as well as the documentation, here is the python snippet to resolve the issue

from selenium import webdriver
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile

profile = FirefoxProfile()
profile.set_preference("browser.helperApps.neverAsk.saveToDisk", 'application/pdf')
driver = webdriver.Firefox(firefox_profile=profile)

driver.get(target_url)
#specific to target_url
driver.find_element_by_css_selector('a[title="Click to Download"]').click()

Answer 3

I've discovered a useful solution that hopefully will help somebody out there.

You can skip the prompt altogether with firefox if you're starting the download with a click by holding the ALT key.

from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.action_chains import ActionChains
...
profile.set_preference("browser.altClickSave", True)
...
element = driver.find_element_by_xpath("//a")
ActionChains(driver).key_down(Keys.ALT).click(element).key_up(Keys.ALT).perform()

This should download any file without needing to specify MIME type of anything.

Answer 4

I spent some time today trying to figure this out (again... had the solution at home but couldn't get to it...) and during that I found this... None of the solutions helped me so I thought I'd offer up what I did to solve this problem.

from selenium import webdriver
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile

dl_path = "/tmp/"
profile = FirefoxProfile()
profile.set_preference("browser.download.folderList", 2)
profile.set_preference("browser.download.manager.showWhenStarting", false)
profile.set_preference("browser.download.dir", dl_path)
profile.set_preference("browser.helperApps.neverAsk.saveToDisk",
                          "text/plain,text/x-csv,text/csv,application/vnd.ms-excel,application/csv,application/x-csv,text/csv,text/comma-separated-values,text/x-comma-separated-values,text/tab-separated-values,application/pdf")

Answer 5

You have two options :

1) Create a custom firefox profile with settings where the download location is pre-decided and firefox does not ask for confirmation to download. Just googled and found a blog that explains how to do it

2) Use sikuli to automate clicks on the download dialog box. Blog explaining- How to use Sikuli

P.S. - Not read the blogs, but I am sure they will give u a clue.

Answer 6

With my using and test in my Selenium UI automation test, configuring the Firefox Profile is more stable than Robot Class. E.g. Disable popping up the System non-webpage Download/Save Dialog.

FirefoxProfile prof = new FirefoxProfile();

ffprofile.setPreference("browser.download.panel.shown", false);
ffprofile.setPreference("browser.helperApps.neverAsk.saveToDisk","application/zip");

//ffprofile.setPreference("browser.download.folderList", 1);  // Default to /home/user/Downloads in Linux.
ffprofile.setPreference("browser.download.folderList", 2); 
ffprofile.setPreference("browser.download.dir", "/tmp");

Answer 7

FirefoxProfile fxProfile = new FirefoxProfile();
 fxProfile.SetPreference("browser.download.panel.shown", false);
 fxProfile.SetPreference("browser.helperApps.neverAsk.openFile", "text/csv,application/vnd.ms-excel");
 fxProfile.SetPreference("browser.helperApps.neverAsk.saveToDisk", "text/csv,application/vnd.ms-excel");
 fxProfile.SetPreference("browser.download.folderList", 2); 
 fxProfile.SetPreference("browser.download.dir", "c:\\mydownloads");
 IwebDriver driver = new FirefoxDriver(fxProfile);
