Use PowerShell to download a file with HTTP, HTTPS, and FTP – 4sysops

Windows PowerShell can be used for downloading files via HTTP and HTTPS protocols. In PowerShell, as an alternative to the Linux curl and wget commands, there is an Invoke-WebRequest command, that can be used for downloading files from URLs.

Have you ever wanted to browse the web via the command line? Me neither. But have you ever needed to pull information from a webpage, monitor a website or submit information via automation? I have and I use Invoke-WebRequest to do it! Invoke-WebRequest along with it's brother, Invite-RestMethod are the two PowerShell cmdlets you'll want to familiarize yourself with if you need to do any kind of web automation. The Invoke-WebRequest cmdlet is a part of the Microsoft.

This cmdlet was included with PowerShell ever since v3 and it's one that is extremely powerful yet easy to use. The cmdlet supports all of the common request methods. By far, the most common method is the GET method. The method is defined by using the Method parameter. Since we need an endpoint to query, we'll also need a URI as well.

To keep this easy, I'll pick any website. To shamelessly promote TechSnips, I'll choose techsnips. When I do this, Invoke-WebRequest downloads the entire web page and returns an output with various parsed information around the elements of the page. To get the videos, I'll need to do some digging. When I look at the links property I see a commonality that all of the video links have a class of ng-binding as shown below. We can also use Invoke-WebRequest to download files from the web as well and it's really easy!

We can download files by simply pointing Invoke-WebRequest at a URI of a file and using the OutFile parameter to tell the cmdlet to save the file to local disk. As an example, powershell invoke-webrequest download file, below I'm downloading the SysInternals Handle utility and expanding the zip file once downloaded.

It's really that easy! We can use Invoke-WebRequest to also fill forms. To do this powershell invoke-webrequest download file, we commonly need to work with web sessions. HTTP is a naturally stateless protocol and your browser in this case PowerShell must be able to create a session which will be used to track things like cookies, for example.

Once we do this, the response will have a Forms property we can then populate with a username and password. In this case, the powershell invoke-webrequest download file is represented by a field called user and the password should be in a field called password, powershell invoke-webrequest download file.

This will depend on the webpage. Once the form has been populated, we can then use Invoke-WebRequest again but this time re-use the session we just created and automatically figure out the URI to send it to by reading the Action property that's on the form as shown below.

Perhaps you need to know what's behind that shortened URL but don't want to click on it to find out! No problem. Notice below I'm also using the UseBasicParsing parameter. This doesn't work on systems without IE, powershell invoke-webrequest download file. To get around that, we can use the UseBasicParsing parameter to still download the content but only lightly parse it.

If there's an action that can be performed via a typical graphical browser, the Invoke-WebRequest cmdlet can do it too. Comments powered by Talkyard. Stay up to date!
