If no valid cached token exists, requests a new token from the TI-Connector by using the supplied credentials and stores it for subsequent requests. The token cache is maintained separately for each connector and its last use time is updated whenever a cached token is returned. .PARAMETER ComputerName The FQDN or IP address of the target TI-Connector. .PARAMETER Credential A PSCredential object containing the username and password used to obtain an authentication token when a new token is required. .OUTPUTS System.String The cached or newly requested bearer token. .EXAMPLE $token = Get-TIConnectorToken -ComputerName 'connector.example' -Credential $credential Returns a valid token for the specified connector, reusing a recent token when available. .NOTES This is an internal helper function and is not exported by the TIConnector module. A new token is requested after the cached token has not been used for four minutes. #> function Get-TIConnectorToken { [CmdletBinding()] param ( [Parameter(Mandatory)] [string]$ComputerName, [Parameter(Mandatory)] [PSCredential]$Credential ) $key = $ComputerName.ToLower() if ($script:ConnectorSessions.ContainsKey($key)) { $session = $script:ConnectorSessions[$key] if ($session.LastUsedAt -gt (Get-Date).AddMinutes(-4)) { $session.LastUsedAt = Get-Date return $session.Token } } $token = New-TIConnectorToken -ComputerName $ComputerName -Credential $Credential $script:ConnectorSessions[$key] = @{ Token = $token LastUsedAt = Get-Date } return $token } |
