Cant filter hashtable returned from function.

[MC2016]

Hello Everyone,

I have the below code and I'm getting data back from the function but unable to filter it by calling $Sessions.Name. Goal is to be able to filter between vcenter and other vami devices. Anyone see what I'm doing wrong with my code or know a better way to filter a list?

function GetVAMISessionID

{

    $BaseAuthURL = "https://" + $ip + "/rest/com/vmware/cis/"

    $SessionURL = $BaseAuthURL + "session"

    $Header = @{"Authorization" = "Basic "+[System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($User+':'+$Password))}

    $Type = "application/json"

    #Authenticate

    Try

    {

        $SessionResponse = Invoke-RestMethod -Uri $SessionURL -Headers $Header -Method POST -ContentType $Type -SkipCertificateCheck

    }

    Catch

    {

        $_.Exception.ToString()

        $error[0] | Format-List -Force

    }

    # Extracting the session ID from the response

    $SessionHeader = @{'vmware-api-session-id' = $SessionResponse.value}

    return $SessionHeader

}

function APIAuth {

    [hashtable]$Sessions = @{}

    #VC1 API Call

if($VC1IP -AND $VC1Username -AND $VC1Password) {

    $User = $VC1Username

    $Password = $VC1Password

    $IP = $VC1IP

    $Sessions.VC1Session = GetVAMISessionID $IP $User $Password

    }

#VC2 API Call

if($VC2IP -AND $VC2Username -AND $VC2Password) {

    $User = $VC2Username

    $Password = $VC2Password

    $IP = $VC2IP

    $Sessions.VC2Session = GetVAMISessionID $IP $User $Password

    }

# PSC1 API Call

if($PSC1IP -AND $PSC1Username -AND $PSC1Password ){

    $User = $PSC1Username

    $Password = $PSC1Password

    $IP = $PSC1IP

    $Sessions.PSC1Session = GetVAMISessionID $IP $User $Password

}

# PSC2 API Call

if($PSC2IP -AND $PSC2Username -AND $PSC2Password){

    $User = $PSC2Username

    $Password = $PSC2Password

    $IP = $PSC2IP

    $Sessions.PSC2Session = GetVAMISessionID $IP $User $Password

}

write-host $Sessions.Name

    Return $Sessions

}

$VC1IP = "xxxxxxxxxxx"

$VC1Username = "administrator@vsphere.local"

$VC1Password = "xxxxxxxxxxxxxxx"

$VC2IP = "xxxxxxxxxxxxx"

$VC2Username = "administrator@vsphere.local"

$VC2Password = "xxxxxxxxxxxxxxxx"

$PSC1IP = "xxxxxxxxxxxxxxxxxxxx"

$PSC1Username = "root"

$PSC1Password = "xxxxxxxxxxxxxxx"

$PSC2IP = "xxxxxxxxxxxxx"

$PSC2Username = "root"

$PSC2Password = "xxxxxxxxxxxxx"

$Sessions = APIAuth $VC1IP $VC1Username $VC1Password $VC2IP $VC2Username $VC2Password $PSC1IP $PSC1Username $PSC1Password $PSC2IP $PSC2Username $PSC2Password

The output from the above code is

$Sessions

Name                           Value

----                           -----

PSC1Session                    {vmware-api-session-id}

VC1Session                     {vmware-api-session-id}

PSC2Session                    {vmware-api-session-id}

VC2Session                     {vmware-api-session-id}

You assign a hash table to the Value of the $sessions hash table.

That means you will have to use double indexing to reach a specific value.

See this simplified example

function f2

{

    $t = @{

        Field1 = 'abc'

    }

    return $t

}

function f1

{

    [hashtable]$h = @{}

    $h.T1 = f2

    return $h

}

$x = f1

$x['T1']['Field1']

Notice how we use ['T1']['Field1'] to reach the value of the nested hash table entry.

Hi LucD,

Understand your example you provided. I'm interested in the information in column "Name" on first hashtable.

Wanting to filer it down with a where statement based on the "Name" column in first hashtable. This possible?

$vcsa = $Sessions | Where { $Sessions.Name -like "VC"}

$Sessions

Name                           Value

----                           -----

PSC1Session                    {vmware-api-session-id}

VC1Session                     {vmware-api-session-id}

PSC2Session                    {vmware-api-session-id}

VC2Session                     {vmware-api-session-id}

You have to include a meta character to handle the rest of the string.

$vcsa = $Sessions | Where { $Sessions.Name -like "VC*"}

Or else use the -match operator

$vcsa = $Sessions | Where { $Sessions.Name -match "VC"}
