I have already been to this link with same question, but I cannot find an answer to it:
Although my question is the same as the other question, I posted a new one with my code as well.
url='https://example.com/'
download_url="https:/example.com/Download"
chromedriver = 'path\\to\chromedriver.exe'
options = Options()
ua = UserAgent()
userAgent = ua.random
print(userAgent)
options.add_argument(f'user-agent={userAgent}')
options.add_experimental_option("prefs", {
"download.default_directory": r"C:\Users\helia\Desktop\Test",
"download.prompt_for_download": False,
"download.directory_upgrade": True,
"safebrowsing.enabled": True
})
options.add_argument("--headless")
options.add_argument("--window-size=%s" % WINDOW_SIZE)
driver = webdriver.Chrome(chrome_options=options, executable_path=chromedriver)
driver.get(url)
user_name = driver.find_element_by_name('User')
pass_word = driver.find_element_by_name("Pass")
user_name.send_keys("my_username")
pass_word.send_keys("my_password")
driver.find_element_by_class_name("btnn.btnn-default.b").click()
driver.get(download_url)
driver.find_element_by_class_name("btn.btn-app").click()
driver.switch_to.alert.accept()
The code successfully downloads the file but the file is 0 KB. both on the website and on my local; however, the file on the site has never been 0 before.
(the program finishes while the file is being downloaded, could it be the cause? do I need to add some waits?)
Your question is not clear enough, however I guess your problem is:
After clicking the download button and accepting the alert your code finishes immediately so downloaded file have had no enough time to be actually downloaded.
In order to get the file completely downloaded you should prevent browser to be closed until the downloading not complete.

After an update in selenium and visual studio I have the following problem. I try to get a url for example
thestore = "http://shop.oki.gr/shop/store/diathesimotita_new.asp" and instead I have a window opened with
http://www.puttop.top/object.php?u=http://shop.oki.gr/shop/store/customerauthenticateform.asp?redirectUrl=http://shop.oki.gr/shop/store/diathesimotita_new.asp&title=Login%20Page
which of course is not working.
options = webdriver.ChromeOptions()
options.add_experimental_option("prefs", {"download.default_directory": downloads_path,
"profile.default_content_settings.popups": 0,
"download.prompt_for_download": False,
"directory_upgrade": True,
"safebrowsing.enabled": True})
browser = webdriver.Chrome(service=Service(ChromeDriverManager().install()),options=options)
thestore = "http://shop.oki.gr/shop/store/diathesimotita_new.asp"
browser.get(thestore)
The initial url is opening from other pc normally..
What is happening?
I cant open either of these but it seems like its redirecting you to a login page first
I have a couple programs that do something similar and I keep a function that login for me on hand, then I get the original url again
Example: https://apps1.lavote.net/camp/comm.cfm?&cid=82
With Selenium, I am clicking the first Form 497. In my browser, a new tab of the pdf opens. In selenium, nothing seems to happen.

print(e)
As you may have guessed, there are no pdfs. They are not downloaded. That's why I'm here. How can I do this?
If you only need the files and not to test the actual browser dialogue routine, grab the files using Python instead of asking Selenium to do that.
Grab the PDF URLs from the page, then use request to download the file to your memory and then open().write() to save it to the file system.
req = requests.get(url, allow_redirects=True)
open(filename, 'wb').write(r.content)
You can also get the filename from r, but it's a bit bothersome. Check it here: https://www.codementor.io/#aviaryan/downloading-files-from-urls-in-python-77q3bs0un
I need to download a set of individual pdf files from a webpage. It is publicly available by government (ministry of education in Turkey) so totally legal.
However my selenium browser only displays the pdf file, how can I download it and name as I wish.
(This code is also from web)
# Import your newly installed selenium package
from selenium import webdriver
from bs4 import BeautifulSoup
# Now create an 'instance' of your driver
# This path should be to wherever you downloaded the driver
driver = webdriver.Chrome(executable_path="/Users/ugur/Downloads/chromedriver")
# A new Chrome (or other browser) window should open up
download_dir = "/Users/ugur/Downloads/" # for linux/*nix, download_dir="/usr/Public"
options = webdriver.ChromeOptions()
profile = {"plugins.plugins_list": [{"enabled": False, "name": "Chrome PDF Viewer"}], # Disable Chrome's PDF Viewer
"download.default_directory": download_dir , "download.extensions_to_open": "applications/pdf"}
options.add_experimental_option("prefs", profile)
# Now just tell it wherever you want it to go
driver.get("https://odsgm.meb.gov.tr/kurslar/KazanimTestleri.aspx?sinifid=5&ders=29")
driver.find_element_by_id("ContentPlaceHolder1_dtYillikPlanlar_lnkIndir_2").click()
driver.get("https://odsgm.meb.gov.tr/kurslar/PDFFile.aspx?name=kazanimtestleri.pdf")
Thanks in advance
Extra information:
I had a python 2 code doing this perfectly. But somehow it creates empty files and I couldn't convert it to python 3. Maybe this helps (no offense but I never liked selenium)

Add your options before launching Chrome and then specify the chrome_options parameter.
download_dir = "/Users/ugur/Downloads/"
options = webdriver.ChromeOptions()
profile = {"plugins.plugins_list": [{"enabled": False, "name": "Chrome PDF Viewer"}],
"download.default_directory": download_dir,
"download.extensions_to_open": "applications/pdf"}
options.add_experimental_option("prefs", profile)
driver = webdriver.Chrome(
executable_path="/Users/ugur/Downloads/chromedriver",
chrome_options=options
)
To answer your second question:
May I ask how to specify the filename as well?
I found this: Selenium give file name when downloading
What I do is:
file_name = ''
while file_name.lower().endswith('.pdf') is False:
time.sleep(.25)
try:
file_name = max([download_dir + '/' + f for f in os.listdir(download_dir)], key=os.path.getctime)
except ValueError:
pass
Here is the code sample I used to download pdf with a specific file name. First you need to configure chrome webdriver with required options. Then after clicking the button (to open pdf popup window), call a function to wait for download to finish and rename the downloaded file.
import os
import time
import shutil
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
# function to wait for download to finish and then rename the latest downloaded file
def wait_for_download_and_rename(newFilename):
# function to wait for all chrome downloads to finish
def chrome_downloads(drv):
if not "chrome://downloads" in drv.current_url: # if 'chrome downloads' is not current tab
drv.execute_script("window.open('');") # open a new tab
drv.switch_to.window(driver.window_handles[1]) # switch to the new tab
drv.get("chrome://downloads/") # navigate to chrome downloads
return drv.execute_script("""
return document.querySelector('downloads-manager')
.shadowRoot.querySelector('#downloadsList')
.items.filter(e => e.state === 'COMPLETE')
.map(e => e.filePath || e.file_path || e.fileUrl || e.file_url);
""")
# wait for all the downloads to be completed
dld_file_paths = WebDriverWait(driver, 120, 1).until(chrome_downloads) # returns list of downloaded file paths
# Close the current tab (chrome downloads)
if "chrome://downloads" in driver.current_url:
driver.close()
# Switch back to original tab
driver.switch_to.window(driver.window_handles[0])
# get latest downloaded file name and path
dlFilename = dld_file_paths[0] # latest downloaded file from the list
# wait till downloaded file appears in download directory
time_to_wait = 20 # adjust timeout as per your needs
time_counter = 0
while not os.path.isfile(dlFilename):
time.sleep(1)
time_counter += 1
if time_counter > time_to_wait:
break
# rename the downloaded file
shutil.move(dlFilename, os.path.join(download_dir,newFilename))
return
# specify custom download directory
download_dir = r'c:\Downloads\pdf_reports'
# for configuring chrome pdf viewer for downloading pdf popup reports
chrome_options = webdriver.ChromeOptions()
chrome_options.add_experimental_option('prefs', {
"download.default_directory": download_dir, # Set own Download path
"download.prompt_for_download": False, # Do not ask for download at runtime
"download.directory_upgrade": True, # Also needed to suppress download prompt
"plugins.plugins_disabled": ["Chrome PDF Viewer"], # Disable this plugin
"plugins.always_open_pdf_externally": True, # Enable this plugin
})
# get webdriver with options for configuring chrome pdf viewer
driver = webdriver.Chrome(options = chrome_options)
# open desired webpage
driver.get('https://mywebsite.com/mywebpage')
# click the button to open pdf popup
driver.find_element_by_id('someid').click()
# call the function to wait for download to finish and rename the downloaded file
wait_for_download_and_rename('My file.pdf')
# close the browser windows
driver.quit()
Set timeout (120) to the wait time as per your needs.
Non-selenium solution, You can do something like:
import requests
pdf_resp = requests.get("https://odsgm.meb.gov.tr/kurslar/PDFFile.aspx?name=kazanimtestleri.pdf")
with open("save.pdf", "wb") as f:
f.write(pdf_resp.content)
Although you might want to check the content type before to make sure it's a pdf
So the issue of downloading files via headless chrome with selenium still seems to be a problem as it was asked here with no answer over a month ago. but I don't understand how they are implementing the js which is in the bug thread. Is there an option I can add or a current fix for this? The original bug page located here
All of my stuff is up to date as of today 10/22/17
In python:
from selenium import webdriver
options = webdriver.ChromeOptions()
prefs = {"download.default_directory": "C:/Stuff",
"download.prompt_for_download": False,
"download.directory_upgrade": True,
"plugins.always_open_pdf_externally": True
}
options.add_experimental_option("prefs", prefs)
options.add_argument('headless')
driver = webdriver.Chrome(r'C:/Users/aaron/chromedriver.exe', chrome_options = options)
# test file to download which doesn't work
driver.get('http://ipv4.download.thinkbroadband.com/5MB.zip')
If the headless option is removed this works no problem.
The actual files I'm attempting to download are PDFs located at .aspx URLs. I'm downloading them by doing a .click() and it works great except not with the headless version. The hrefs are javascript do_postback scripts.
Why don't you locate the anchor href and then use get request to download the file. This way it will work in headless mode and will be much faster. I have done that in C#.
def download_file(url):
local_filename = url.split('/')[-1]
# NOTE the stream=True parameter
r = requests.get(url, stream=True)
with open(local_filename, 'wb') as f:
for chunk in r.iter_content(chunk_size=1024):
if chunk: # filter out keep-alive new chunks
f.write(chunk)
#f.flush() commented by recommendation from J.F.Sebastian
return local_filename
I believe now that Chromium supports this feature (as you linked to the bug ticket), it falls to the chromedriver team to add support for the feature. There is an open ticket here, but it does not appear to have a high priority at the moment. Please, everyone who needs this feature, go give it a +1!
For those of you not on the chromium ticket linked above or haven't found a solution. This is working for me. Chrome is updated to v65 and chromedriver/selenium are both up to date as of 4/16/18.
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're getting a Failed-file path too long error when downloading make sure that the downloadpath does't have a trailing space or slash\or backslash. The path must also use backslashes only. I have no idea why.
I am using Selenium 2.43.0 with Python 2.7.5. At one point, the test clicks on a button which sends form information to the server. If the request is successful, the server responds with
1) A successful message
2) A PDF with the form information merged in
I don't care to test the PDF, my test is just looking for a successful message. However the PDF is part of the package response from the server that I, as the tester, cannot change.
Until recently, this was never an issue using Chromedriver, since Chrome would automatically download pdfs into its default folder.
However, a few days ago one of my test environments started popping a separate window with a "Print" screen for the pdf, which derails my tests.
I don't want or need this dialog. How do I suppress this dialog programmatically using chromedriver's options? (Something equivalent to FireFox's pdfjs.disable option in about:config).
Here is my current attempt to bypass the dialog, which does not work (by "not work" does not disable or suppress the print pdf dialog window):
dc = DesiredCapabilities.CHROME
dc['loggingPrefs'] = {'browser': 'ALL'}
chrome_profile = webdriver.ChromeOptions()
profile = {"download.default_directory": "C:\\SeleniumTests\\PDF",
"download.prompt_for_download": False,
"download.directory_upgrade": True}
chrome_profile.add_experimental_option("prefs", profile)
chrome_profile.add_argument("--disable-extensions")
chrome_profile.add_argument("--disable-print-preview")
self.driver = webdriver.Chrome(executable_path="C:\\SeleniumTests\\chromedriver.exe",
chrome_options=chrome_profile,
service_args=["--log-path=C:\\SeleniumTests\\chromedriver.log"],
desired_capabilities=dc)
All component versions are the same in both testing environments:
Selenium 2.43.0, Python 2.7.5, Chromedriver 2.12, Chrome (browser) 38.0.02125.122
I had to dig into the source code on this one - I couldn't find any docs listing the full set of Chrome User Preferences.
The key is "plugins.plugins_disabled": ["Chrome PDF Viewer"]}
FULL CODE:
dc = DesiredCapabilities.CHROME
dc['loggingPrefs'] = {'browser': 'ALL'}
chrome_profile = webdriver.ChromeOptions()
profile = {"download.default_directory": "C:\\SeleniumTests\\PDF",
"download.prompt_for_download": False,
"download.directory_upgrade": True,
"plugins.plugins_disabled": ["Chrome PDF Viewer"]}
chrome_profile.add_experimental_option("prefs", profile)
#Helpful command line switches
# http://peter.sh/experiments/chromium-command-line-switches/
chrome_profile.add_argument("--disable-extensions")
self.driver = webdriver.Chrome(executable_path="C:\\SeleniumTests\\chromedriver.exe",
chrome_options=chrome_profile,
service_args=["--log-path=C:\\SeleniumTests\\chromedriver.log"],
desired_capabilities=dc)
Interestingly the blanket command chrome_profile.add_argument("--disable-plugins") switch did not solve this problem. But I prefer the more surgical approach anyways.
