Downloading a file at a specified location through

问题:

I am trying to automatically download some links through selenium's click functionality and I am using a chrome webdriver and python as the programming language. How can I select the download directory through the python program so that it does not get downloaded in the default Downloads directory. I found a solution for firefox but there the download dialog keeps popping up every time it clicks on the link which does not happen in Chrome.

Update 2018:

Its not valid Chrome command line switch, see the source code use hoju answer below to set the Preferences.

Original:

You can create a profile for chrome and define the download location for the tests. Here is an example:

from selenium import webdriver

options = webdriver.ChromeOptions() 
options.add_argument("download.default_directory=C:/Downloads")

driver = webdriver.Chrome(chrome_options=options)

I found the accepted solution didn't work, however this slight change did:

import webdriver
chrome_options = webdriver.ChromeOptions()
prefs = {'download.default_directory' : '/path/to/dir'}
chrome_options.add_experimental_option('prefs', prefs)
driver = webdriver.Chrome(chrome_options=chrome_options)

the exact problem I also have faced while trying to do exactly same what you want to :)

For chrome:

from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("--start-maximized")
prefs = {"profile.default_content_settings.popups": 0,
             "download.default_directory": 
                        r"C:\Users\user_dir\Desktop\\",#IMPORTANT - ENDING SLASH V IMPORTANT
             "directory_upgrade": True}
options.add_experimental_option("prefs", prefs)
browser=webdriver.Chrome(<chromdriver.exe path>, options=options)

For Firefox: follow this blog for the answer: https://srirajeshsahoo.wordpress.com

The blog says all about the pop up and download dir and how to do

To provide download directory and chrome's diver executable path use the following code.

from selenium import webdriver
options = webdriver.ChromeOptions() 
options.add_argument("download.default_directory=C:/Your_Directory")
driver = webdriver.Chrome(options=options ,executable_path='C:/chromedriver')

change the path in your code accordingly.

If you are using linux distribution

Use this code

prefs = {'download.prompt_for_download': False,
         'download.directory_upgrade': True,
         'safebrowsing.enabled': False,
         'safebrowsing.disable_download_protection': True}

options.add_argument('--headless')
options.add_experimental_option('prefs', prefs)
driver = webdriver.Chrome('chromedriver.exe', chrome_options=options)
driver.command_executor._commands["send_command"] = ("POST", '/session/$sessionId/chromium/send_command')
driver.desired_capabilities['browserName'] = 'ur mum'
params = {'cmd': 'Page.setDownloadBehavior', 'params': {'behavior': 'allow', 'downloadPath': r'C:\chickenbutt'}}
driver.execute("send_command", params)

If you are using script only on your local machine then use this solution

Click on Menu -> Setting -> Show advanced settings... -> Downloads

Now uncheck

Ask where to save each file before downloading

Hope it will help you :)
