How to output json object returned from REST api in powershell?

Question

I am trying to output to console a json object that is being returned when I call the URL:

http://localhost:999/api/randomObjects/19

where randomObjects is the type of object and 19 is the object ID. So far, the only way I have gotten the json to output to the console in powershell is using webclient and saving the json to a folder then outputting it.

$storageDir = "C:\Path\to\folder"
$webclient = New-Object System.Net.WebClient
$url = "http://localhost:999/api/randomObjects/19"
$file = "$storageDir/demofile.json"
$webclient.DownloadFile($url,$file)
cat $file

Is there a way to directly output the json object to console without saving it in a file?

There sure is: See the ConvertTo-Json and ConvertFrom-Json cmdlets. These will transform to and from the JavaScript Object Notation textual format into a custom PSObject that you can query and manipulate using the regular tricks of the trade.

Hah... yes, I know I've been absent for a few months now. It's also hard to beat MVP buggers like you to the punch :D

Thanks, this worked out great. For some reason it won't let me mark your answer as correct? Keeps saying "an error has occurred". I'll try again in a bit.

This may be a more direct method; if the API returns a JSON then it will convert to a PSObject if possible*.

$response = Invoke-RestMethod -Uri http://localhost:999/api/randomObjects/19

*if possible means "as long as the JSON isn't too big". See also:

Invoke-RestMethod doesn't create PS object out of JSON
