I currently have a link to pdf and doc which is hosted on my server. Using selenium i opened headless chrome and hit the docx link and the document got downloaded but pdf is not getting downloaded..reason being pdf is being viewed in the browser instead of getting downloaded.
Example :- When you click this link. you can view the image.
Is there any attribute kind of parameter which i can append to the url and the pdf (or) image gets downloaded?
One thing you could do is modify the browser settings first to force PDF downloads, for instance by opening chrome://settings/content/pdfDocuments and then pressing the #knob button to activate this setting.
That I assume you're using Chrome obviously but there may be analogous settings in other browsers.

I have a Python app navigating through a website using Webbot. On the final page, it renders and streams a PDF to the browser (without an endpoint URL). This is displayed in the chrome PDF viewer but I need to download this.
I am unsure of how to go about activating the download here or obtaining this file through the normal method of request.get()
The URL is generic: www.website.com/generatePDF
chrome viewer showing download button
I can navigate to this page, I'm just not sure how to go about getting the actual PDF downloaded. Because everything uses scripting on the backend, I need to navigate button clicks (URL's are hidden).
Thoughts?
Have you consider sending CTRL+S command? It should send the save command and then click on SAVE button. Never tried but could do the job.
I am new to python selenium and I need more explanation on the effect of the below code on selenium Firefox profile.
profile.set_preference('browser.helperApps.neverAsk.saveToDisk', ('application/vnd.ms-excel'))
Firefox browser is by default asking if to save or to open the file when user tries to download a file.
To prevent Firefox opening that dialog we can predefine not to ask this for predefined types of files.
Each file type should be mentioned explicitly with such setting in order to not ask when downloading of such a kind of file initiated.
Basically when setting up your Firefox profile you add a call to set the property browser.helperApps.neverAsk.saveToDisk like this.
You won't face download pop up.
so basically it means that download any file and save it to the desired location using Selenium Webdriver.
After some research on my problem, it seems I should use either requests or urllib or both.
So basically, I am trying to learn the code I need to download a csv file from this url:
https://globalaccess.sustainalytics.com/#/tools/0
The way I manually download my files is as follows: first, I need to log in using username and password. Next I have to go to a tab called "Screening" that takes to me another page that has several buttons called "Generate". I click a specific generate button (it's always the same one) among the option to get the excel file. After that I have the option to save the file or open from a little window within the website.
My question is what code can I use on Python to download and save the file in a particular folder?
Use Selenium
https://selenium-python.readthedocs.io/
You'll need to download a 'chromedriver' to the same directory as your python script, then use the intro tutorial on the selenium docs site to drive the browser to type/click where you want.
If you use chrome you can right click on any given link/input box click inspect, then in the window that comes up right click the bit of highlighted code and 'copy xpath'. Use the find element by xpath function in Selenium to send keys or clicks to that element.
I want to download some images (<10000) from a website.
I can't directly use the following python to directly download since the website requires username/password, it will give a 'HTTP Error 401: Unauthorized' error.
f = open(output_path, 'wb')
f.write(request.urlopen(full_image_url).read())
f.close()
So my current work around is to
log in to the website in Chrome - Easily Done
use python to parse (I manually copied the page source) and open lots of image links in chrome using
webbrowser.get(chrome_path).open(full_image_url) - This is Done
save the image from browser to local hard drive.
For step 3, I can manually right click each chrome tab to 'save image as'. But is there an automatic way to do so?
Any suggestion, help link, or other work around solution would be appreciated.
Have you tried logging into the site using python?
Take a look at this: How can I login to a website with Python?
I am trying to get python to open a local html file in firefox and then use a addon called "download all" to download the images to a specific folder. I am not able to scrape them for some weird reason. If I can't do it this way I would want to use xpath to do it since the image links are laid out in tables. Is this possible?
You can't click on the element since it's not a web page element. However you can create a profile for firefox and include addons in that profile that is launched by the webdriver applications. This will allow you to have access to Firebug or other addons. you can set a profile and extend the profile with the addon api is like so:
File file = new File("addonName.xpi");
FirefoxProfile firefoxProfile = new FirefoxProfile();
firefoxProfile.addExtension(file);
firefoxProfile.setPreference("extensions.addOn.currentVersion", "1.8.1"); // Avoid startup screen
WebDriver driver = new FirefoxDriver(firefoxProfile);
Thanks
