Is there a way to fetch Response header for InvokeRest Method of Powershell Version 5

Question

How can I fetch Response header for InvokeRest Method of Powershell Version 5, For Powershell version 6 -ResponseHeadersVariable is available , Is there any way to do it in powershell version 5. I am unable to find any way to do it.

Answer 1

I don't think there is a way to get response headers of Invoke-RestMethod in v5 but you can easily replace that with something like

$headers = Invoke-WebRequest 'example.com' | select headers

Adding some context of your scenario can help to suggest more suitable approach.

Answer 2

I am using powershell core and Invoke-RestMethod now has a parameter for getting response headers.

♥ pwsh::github$ $null = Invoke-RestMethod -Uri https://google.com -ResponseHeadersVariable rh
