List VM's from API using powershell

[frankU32]

Hello,

I need to list all the VM's currently managed by Veeam from the API with I am accessing via Powershell. I have the following :

Code: Select all

$ValidToken = Getveeamtoken

$response = Invoke-WebRequest -Uri http://veeam-srv:9399/api/managedServers -Method "GET" -Headers @{"X-RestSvcSessionId" = $ValidToken} 

$response

The problem I am having is making sense of the response. I can see the information I want is there and It looks like it's in XML but I can't get anything in PowerShell to do anything with it. 'select-xml' can't parse it and I cant convert it to JSON either. It's like the response is malformed in some way, which I'm sure it isn't. I could just use something like "-match" to get the results I want but I would rather do it properly.

Can anyone point me in the right direction please.

Hmm, if backup server is added to Enteprise Manager, why not to interact with it directly via PowerShell, instead of doing it with rather complicated approach (PowerShell invocation of RESTful API)? Thanks.

I don't have access to the server via powershell, I only have access to the api

I have never done it personally, but I think you should declare XML variable and only then parse it, similar to this example. Thanks.

you will need to drill in the Content and the XML file

Example:

Code: Select all

$response = Invoke-WebRequest -Uri http://veeam-srv:9399/api/managedServers -Method "GET" -Headers @{"X-RestSvcSessionId" = $ValidToken} 
$bn = ([xml]$response.Content)
$bn

you can dril into the XML keys by adding them to the end of $bn = ([xml]$response.Content)

Like

Code: Select all

$bn = ([xml]$response.Content).EntityReferences
$bn

you can keep drilling in with adding a period then the key name

here is an example I am writing

Code: Select all

function _Fetch_Replicas($Token,$Urli) {
	# Ref: https://helpcenter.veeam.com/docs/backup/rest/replicas.html?ver=95u4
	## Fetch Replicas
	write-host "Fetching Replica VMs..."  -foreground "yellow"
	$ResourceUri = $Urli + 'backupSessions'
	write-host "Using URL:" $ResourceUri -foreground "green"
	
	# Additional Headers
	$hdrs = @{
		'X-RestSvcSessionId' = $Token
		ContentType = "application/json"
	}
	
	# Paramenters to send
	$Params = @{
		URI = $ResourceUri
		Method = "GET"
		Headers = $hdrs
	}
	
	$res = Invoke-WebRequest @Params
	#$bn = ([xml]$res.Content).EntityReferences.Ref.Links.Link
	$bn = ([xml]$res.Content).EntityReferences.ref
	$bn
}
