By default, the Invoke-WebRequest cmdlet downloads the file to the current directory. On Windows 10, there are two aliases available for the Invoke-WebRequest cmdlet: curl and wget. So, to download a file from the Internet website, you can use a shorter command. 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 will 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 current user.
To add a little extra security, you might want to encrypt the password. 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.
