Invoke-WebRequest with currently logged in user credentials?

Question

I have an Azure App Service running Linux configured with Azure AD authentication per this Microsoft document.

Everything works fine if I access the site via a browser, as it handles all the necessary bits to authenticate as the user. I'm not sure how to go about authenticating as the current user (which is an AAD account) logged into Windows via Invoke-WebRequest in PowerShell though. I'm assuming I need to retrieve some kind of token to pass along with Invoke-WebRequest.

Answer 1

Try this switch.

-UseDefaultCredentials

Indicates that the cmdlet uses the credentials of the current user to send the web request.

Here's an example that shows the use of -SessionVariable and -WebSession parameters to connect to a site and then make subsequent requests.
