Invoke-webrequest download file

You can stop a single job based on its JobId or all jobs with:. When using Asynchronous it creates a temp file during the download process. But to actually use the file you will need to run the following cmdlet:. Instead, we can simply use the Copy-Item cmd to download a file from a server. If you want to know more about the Copy-Item cmdlet, then you should read this article where I explain more about the cmdlet and alternatives.

The method to download zip files is pretty much the same as a normal file. But I wanted to show you how that downloads and extracts the zip file. This way you can immediately process the files inside the zip file without manual interaction. I am going to use this sample csv on GitHub which we can download in a zip file. We have to set a destination for the zip file itself and a path where we want to extract the files to. The next step is to extract the zip file automatically in the desired location.

For this we are going to use a COM object. With the COM object we can extract the zip file and copy the content to the desired location. 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.

We can use Invoke-WebRequest to also fill forms. To do this though, 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.

To download a file from an FTP server with authorization, you need to specify the FTP username and password in the script:. On Windows 10, you can use the built-in Invoke-WebRequest cmdlet to download files this cmdlet is available in all versions since PowerShell 3. You would somehow need to enumerate the content of the folder and then download it.

That is normally forbidden by webservers. Then you could parse the output and ask for specific files to be downloaded or all of them.

But I dont see any straight-forward way. This works fine but I cannot step through this content. When I put this content through a foreach loop it dumps every line at once. If I save it to a file then I can use System. File::ReadLines to steps through line by line but that only works if I download the file. How can I accomplish this without downloading the file?

You can't parse text files with Invoke-WebRequest. If the text file is unstructured you can parse it with regex. More information about using regex in PowerShell can be found here and here. I am trying to download files from a site, sadly they are be generated to include the Epoch Unix timestamp in the file name. Now as I am unable to replace the Epoch Unix timestamp portion of the file name with a wild card, I was wondering if there was a way to do the download based on the date modified field of the file?

Thanks for this. I plan to use this along with task scheduler to download a fresh file every week. However, the new file overwrites the older one. Is there a way to preserve the older file as well? Ken - You should be able to relatively easily - however, you'd have to download it first, since you can't get the file properties until you download it.

You could download it to a temp location, grab the LastWriteTime stamp and parse it to create your new name. Sumit - You have a similar situation. You'll also need to manage the old copies so you don't fill up your disk.
