Announcing PowerShell Information Server (PSIS)

Johan Akerstrom – PowerShell expert from Sweden – released a PowerShell module that can be used to start a PowerShell-based web server. He preferred to call it a PowerShell Information Server (PSIS). Although, I am not really sure about the name given to it, I completely love the concept and work he did.

This module is available on Github. It is very easy to use and work with.

Invoke-PSIS -URL "http://*:8087/" -AuthenticationSchemes negotiate -ProcessRequest {
    Write-Verbose $request.RequestBody
    Get-Service $request.RequestObject.ServiceName
} -Verbose -Impersonate

This gets the web server started. The -ProcessRequest is what gets executed when a request arrives at the web server. So, in my example, I am just getting the service information.

We can call the end point we just started using the Invoke-RestMethod cmdlet.

$data = [pscustomobject]@{
   ServiceName = "winmgmt"
}
$postData = $data | ConvertTo-Json
Invoke-RestMethod -Method post -Uri 'http://localhost:8087/json' -UseDefaultCredentials -Body $postData | ConvertTo-Json

I already have a list of things I want to try. Go ahead and try the module and leave your feedback for Johan.
