How to bypass the alert window while downloading a zipfile?

If I open the link: https://dibbs2.bsm.dla.mil/Downloads/RFQ/Archive/ca210731.zip
This link shows the window and I need to press the OK button and it downloads the file.
The alert is not from the browser, it is from the page itself.
But When I tried the script:
from io import BytesIO
from zipfile import ZipFile
import requests
def get_zip(file_url):
url = requests.get(file_url)
zipfile = ZipFile(BytesIO(url.content))
zipfile.extractall("")
file_link ='https://dibbs2.bsm.dla.mil/Downloads/RFQ/Archive/ca210731.zip'
get_zip(file_link)
This throws the error:
zipfile.BadZipFile: File is not a zip file
And when I tried:
import requests
url = r'https://dibbs2.bsm.dla.mil/Downloads/RFQ/Archive/ca210731.zip'
output = r'downloadedfile.zip'
r = requests.get(url)
with open(output, 'wb') as f:
f.write(r.content)
This downloads the content of the page showing the OK button.
Any idea how to solve this:, the link downloads the zip file.

I believe you are accepting answer using selenium, Here's what you can do using selenium :
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
profile = webdriver.FirefoxProfile()
profile.set_preference("browser.download.folderList",1)
# 0 for desktop
# 1 for default download folder
# 2 for specific folder
# You can specify directory by using profile.set_preference("browser.download.dir","<>")
profile.set_preference("browser.helperApps.neverAsk.saveToDisk", "application/octet-stream")
profile.set_preference("browser.helperApps.alwaysAsk.force", False);
# If you don't have some download manager then you can remove these
profile.set_preference("browser.download.manager.showWhenStarting",False)
profile.set_preference("browser.download.manager.useWindow", False);
profile.set_preference("browser.download.manager.focusWhenStarting", False);
profile.set_preference("browser.download.manager.alertOnEXEOpen", False);
profile.set_preference("browser.download.manager.showAlertOnComplete", False);
driver=webdriver.Firefox(firefox_profile=profile,executable_path="<>")
driver.get("https://dibbs2.bsm.dla.mil/Downloads/RFQ/Archive/ca210731.zip")
driver.find_element_by_id("butAgree").click()
Here we are setting some profiles to disable pop out, download dialog.
It is working perfectly fine in latest version of Firefox and 3.141.0 version of selenium

Save PDF by using Selenium and IE Browser

To save PDF by using CHrome Browser does not cause any issues (I'm using these options):
options.add_experimental_option('prefs',{
'credentials_enable_service': False,
'plugins':{
'always_open_pdf_externally': True
},
'profile': {
'password_manager_enabled': False,
},
'download': {
'prompt_for_download': False,
'directory_upgrade': True,
'default_directory': ''
}
})
BUT .... How to save PDF by using webdriver.Ie() Internet Explorer Driver with Python + Selenium?
P.S. AFAIK Internet explorer can not be executed by using headless mode, but if someone will not the way to do it, will be amazing !!!

You can't use Selenium to deal with the download prompt in IE because that's an OS-level prompt. Selenium WebDriver has no capability to automate OS-level prompt window. You need to use some 3rd party tools to help you to download file in IE using Selenium.
Here I use Wget to bypass the download prompt and download file in IE. You can refer to this article about how to use Wget.
About using headless mode in IE in Selenium, you can also use a 3rd party tool called headless_ie_selenium. You can download this tool and use headless_ie_selenium.exe instead of IEDriverServer.exe to automate IE.
The sample code to download a pdf file is like below, please note to change the paths in the code to your owns:
from selenium import webdriver
import time
import os
url = "https://file-examples.com/index.php/sample-documents-download/sample-pdf-download/"
driver = webdriver.Ie('D:\\headless-selenium-for-win-v1-4\\headless_ie_selenium.exe')
driver.get(url)
time.sleep(3)
link = driver.find_elements_by_class_name("download-button")[0]
hrefurl = link.get_attribute("href")
os.system('cmd /c C:\\Wget\\wget.exe -P D:\\Download --no-check-certificate ' + hrefurl)
print("*******************")

Python download href, got the source code instead of a pdf file

I'm trying to download a pdf file with the following href (i change some value cause the pdf contain personal information)
https://clients.direct-energie.com/grandcompte/factures/consulter-votre-facture/?tx_defacturation%5BdoId%5D=857AD9348B0007984D4B128F1E8BE&cHash=7b3a9f6d109dde87bd1d95b80ca1d
When i past this href in my browser the pdf file is directly download, but when i'm trying to use request in my python code its only download the source code of
https://clients.direct-energie.com/grandcompte/factures/consulter-votre-facture/
Here is my code, i use selenium to find the href in the website
fact = driver.find_element_by_xpath(url)
href = fact.get_attribute('href')
print(href) // href is correct here
reply = get(href, Stream=True)
print(reply) // I got the source code
Here is the html find by selenium
I hope you have enough informations to help, Thx

Can't use your link because it required auth so found another example of a redirecting pdf download. Setting Chrome to download the pdf instead of displaying it taken from this StackOverflow answer.
import selenium.webdriver
url = "https://readthedocs.org/projects/selenium-python/downloads/pdf/latest/"
download_dir = 'C:/Dev'
profile = {
"plugins.plugins_list": [{"enabled": False, "name": "Chrome PDF Viewer"}],
"download.default_directory": download_dir ,
"download.extensions_to_open": "applications/pdf"
}
options = selenium.webdriver.ChromeOptions()
options.add_experimental_option("prefs", profile)
driver = selenium.webdriver.Chrome(options=options)
driver.get(url)
From looking at the docs, the driver.get method doesn't return anything, it's just telling the webdriver to navigate to a page. If you want to handle the pdf in Python before saving it to a file then perhaps look at using Requests or Robobrowser.
Stream=True option wasn't available for webdriver.Chrome so not sure if this is the method you were using but the above should do what you want.

Selenium Python Download popup pdf with specific filename

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)
import urllib
import urllib2
from bs4 import BeautifulSoup
import os
sinifId=5
maxOrd = 1
fileNames=[]
directory = '/Users/ugur/Downloads/Hasan'
print 'List of current files in directory '+ directory+'\n---------------------------------\n\n'
for current_file in os.listdir(directory):
if (current_file.find('pdf')>-1 and current_file.find(' ')>-1):
print current_file
order = int(current_file.split(' ',1)[0])
if order>maxOrd: maxOrd=order
fileNames.append(current_file.split(' ',2)[1])
print '\n\nStarting download \n---------------------------------\n'
ctA=int(maxOrd+1)
for ders in [29]:
urlSinif='http://odsgm.meb.gov.tr/kurslar/KazanimTestleri.aspx?sinifid='+str(sinifId)+'&ders='+str(ders)
page = urllib2.urlopen(urlSinif)
soup = BeautifulSoup(page,"lxml")
st = soup.prettify()
count=st.count('ctl00')-1
dersAdi = soup.find('a', href='/kurslar/CevapAnahtarlari.aspx?sinifid='+str(sinifId)+'&ders='+str(ders)).getText().strip()
for testNo in range(count):
if(str(sinifId)+str(ders)+str(testNo+1) in fileNames):
print str(ctA)+' '+str(sinifId)+str(ders)+str(testNo+1)+' '+dersAdi+str(testNo+1)+'.pdf'+' skipped'
else:
annex=""
if(testNo%2==1): annex="2"
eiha_url = u'http://odsgm.meb.gov.tr/kurslar/KazanimTestleri.aspx?sinifid='+str(sinifId)+'&ders='+str(ders)
data = ('__EVENTTARGET','ctl00$ContentPlaceHolder1$dtYillikPlanlar$ctl'+format(testNo, '02')+'$lnkIndir'+annex), ('__EVENTARGUMENT', '39')
print 'ctl00$ContentPlaceHolder1$dtYillikPlanlar$ctl'+format(testNo, '02')+'$lnkIndir'+annex
new_data = urllib.urlencode(data)
response = urllib2.urlopen(eiha_url, new_data)
urllib.urlretrieve (str(response.url), directory+'/{0:0>3}'.format(ctA)+' '+str(sinifId)+str(ders)+str(testNo+1)+' '+dersAdi+str(testNo+1)+'.pdf')
print str(ctA)+' '+str(sinifId)+str(ders)+str(testNo+1)+' '+dersAdi+str(testNo+1)+'.pdf'+' downloaded'
ctA=ctA+1

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

PhantomJS (Selenium) Cannot Load PDFs from direct urls

I was trying to save some PDF from a link via PhantomJS (selenium). So, I refered to this code that turns webpages to pdfs. and it worked just fine when I ran the exactly same code.
So, I have this pdf I wanted to save from a direct url and I tried that script... it didn't work. It just saves a PDF with 1 white page. That's all...
My Code :
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
def execute(script, args):
driver.execute('executePhantomScript', {'script': script, 'args' : args })
driver = webdriver.PhantomJS('phantomjs')
# hack while the python interface lags
driver.command_executor._commands['executePhantomScript'] = ('POST', '/session/$sessionId/phantom/execute')
driver.get('http://www.planetpublish.com/wp-content/uploads/2011/11/The_Scarlet_Letter_T.pdf')
try:
WebDriverWait(driver, 40).until(EC.presence_of_element_located((By.ID, 'plugin')))
except Exception as TimeoutException:
print("I waited for far too long and still couldn't fine the view.")
pass
# set page format
# inside the execution script, webpage is "this"
pageFormat = '''this.paperSize = {format: "A4", orientation: "portrait" };'''
execute(pageFormat, [])
# render current page
render = '''this.render("test2.pdf")'''
execute(render, [])
I'm not sure what's happening and why is it happening. Need some assistance.
EDIT: This is just the test PDF that I was trying to get via Selenium. There are some other PDFs which I need to get and that website is checking god-knows-what to decide whether it's a human or a bot. So, Selenium is the only way.
EDIT 2 : So, here's the website I was practicing on : http://services.ecourts.gov.in/ecourtindia/cases/case_no.php?state_cd=26&dist_cd=8&appFlag=web
Select "Cr Rev - Criminal Revision" from "Case Type" drop down and input any number in case number and year. Click on "Go".
This will show a little table, click on "view" and it should show a table on full page.
Scroll down to the "orders" table and you should see "Copy of order". That's the pdf I'm trying to get.I have tried requests as well and it did not work.

Currently, PhantomJS and Chrome headless doesn't support download a file. If you are OK with Chrome browser, please see my example below. It finds a elements, and then add an attribute download. Finally, it clicks on the link to download the file to default Downloads folder.
import time
driver = webdriver.Chrome()
driver.get('http://www.planetpublish.com/free-ebooks/93/heart-of-darkness/')
pdfLinks = driver.find_elements_by_css_selector(".entry-content ul > li > a")
for pdfLink in pdfLinks:
script = "arguments[0].setAttribute('download',arguments[1]);"
driver.execute_script(script, pdfLink, pdfLink.text)
time.sleep(1)
pdfLink.click()
time.sleep(3)
driver.quit()

If you're just looking at downloading PDFs which aren't protected behind some javascript or stuff (essentially straightforward stuff), I suggest using the requests library instead.
import requests
url ='http://www.planetpublish.com/wp-content/uploads/2011/11/The_Scarlet_Letter_T.pdf'
r = requests.get(url)
with open('The_Scarlet_Letter_T.pdf', 'wb') as f:
f.write(r.content)
# If large file
with requests.get(url, stream=True) as r:
with open('The_Scarlet_Letter_T.pdf', 'wb') as f:
for chunk in r.iter_content(chunk_size=1024):
if chunk:
f.write(chunk)

I recommend you look at the pdfkit library.
import pdfkit
pdfkit.from_url('http://www.planetpublish.com/wp-content/uploads/2011/11/The_Scarlet_Letter_T.pdf', 'out.pdf')
It makes downloading pdfs very simple with python. You will also need to download this for the library to work.
You could also try the code from this link shown below
#!/usr/bin/env python
from contextlib import closing
from selenium.webdriver import Firefox # pip install selenium
from selenium.webdriver.support.ui import WebDriverWait
# use firefox to get page with javascript generated content
with closing(Firefox()) as browser:
browser.get('http://www.planetpublish.com/wp-content/uploads/2011/11/The_Scarlet_Letter_T.pdf')
button = browser.find_element_by_name('button')
button.click()
# wait for the page to load
WebDriverWait(browser, timeout=10).until(
lambda x: x.find_element_by_id('someId_that_must_be_on_new_page'))
# store it to string variable
page_source = browser.page_source
print(page_source)
which you will need to edit to make work for your pdf.
