Script to download files from website
If you are working in a hybrid IT environment, you often need to download or upload files from or to the cloud in your PowerShell scripts. If you only use Windows servers that communicate through the Server Message Block SMB protocol, you can simply use the Copy-Item cmdlet to copy the file from a network share:. This assumes that you have a VPN solution in place so that your cloud network virtually belongs to your intranet.
Things get a bit more complicated if we are leaving the intranet and have to download from an extranet or the Internet. The next simple case is where you have to download a file from the web or from an FTP server, script to download files from website. In PowerShell 2, you had to use the New-Object cmdlet for this purpose:.
As of PowerShell 3, we have the Invoke-WebRequest cmdlet, which is more convenient to work with. This is perhaps an understatement; Invoke-WebRequest is more powerful than wget because it allows you to not only download files but also parse them.
But this is a topic for another post. In the example, we just download the HTML page that the web server at www. com generates. Note that, if you only specify the folder without the file name, as you can do with Copy-ItemPowerShell will error:. If you omit the local path to the folder, Invoke-WebRequest will just use your current folder. The -Outfile parameter is always required if you want to save the file. The reason is that, by default, Invoke-WebRequest sends the downloaded file to the pipeline.
However, the pipeline will then not just contain the contents of the file. Instead, you will find an object with a variety of properties and methods that allow you to analyze text files. To only read the contents of the text file, we need to read the Content property of the object in the pipeline:. This command does the same thing as the previous one. If you want to have the file in the pipeline and store it locally, you have to use -PassThru parameter:.
Note that, if you omit the -Credential parameter, PowerShell will not prompt you for a user name and password and script to download files from website throw this error:. You have to at least pass the user name with the -Credential parameter. PowerShell will then ask for the password. If you want to avoid a dialog window in your script, you can store the credentials in a PSCredential object:.
You can use the -UseDefaultCredentials parameter instead of the -Credential parameter if you want to use the credentials of the script to download files from website user.
To add a little extra security, you might want to encrypt the password. Make sure to always use HTTPS instead of HTTP if you have to script to download files from website on a remote server.
If the web server uses basic authentication, your password will be transmitted in clear text if you download via HTTP. Note that this method only works if the web server manages authentication.
Nowadays, most websites use the features of a content management system CMS to authenticate users. Usually, you then have to fill out an HTML form. I will explain in one of my next posts how you can do this with Invoke-WebRequest. Downloading files through FTP works analogous to HTTP. To download multiple files securely, you had better work with SFTP or SCP. However, script to download files from website, third-party PowerShell modules exist that step into the breach.
In my next post I will show you can use Invoke-WebRequest to parse HTML pages and scrape content from websites. Join the 4sysops PowerShell group! Your question was not answered? Ask in the forum! I am running a script on a scheduled basis daily to download a.
csv file. However the uri changes every month, so I was wondering if the uri destination value can be set based on a value in a reference file as opposed to hard coding it, if so how? You can store the URI in a text file and then read it in your script with Get-Content. i am downloading a zip file from a website using the PowerShell, however the issue is that i have to filter by date to download that zip file. Is the date on the website? Then use Invoke-WebRequest to read and then adapt the script to get the right URL of the zip.
Will take some coding. Great tips, can you tell me how you would apply this same concept in powershell to download all files from a web folder? Thank you in advance. Im not sure whether this is possible. 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, script to download files from website. 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.
