function New-ArmorApiUriQuery { <# .SYNOPSIS Builds the Armor API URI with a server-side filter. .DESCRIPTION Builds a server-side filtering URL with a query string if there are any parameter names or aliases specified in the calling cmdlet that match the filter keys in the `Query` key. .INPUTS None- this function does not accept pipeline inputs. .NOTES - Troy Lindsay - Twitter: @troylindsay42 - GitHub: tlindsay42 .EXAMPLE $keys = ( $resources.Query | Get-Member -MemberType 'NoteProperty' ).Name; New-ArmorApiUriQuery -Keys $keys; $parameters = ( Get-Command -Name $function ).Parameters.Values; New-ArmorApiUriQuery -Keys $keys -Parameters $parameters -Uri 'https://api.armor.com/vms' This is not a real example, but if valid, it would return the input URI with a 'Name' server-side filter (eg: https://api.armor.com/vms?name=TEST-VM) .LINK https://tlindsay42.github.io/ArmorPowerShell/private/New-ArmorApiUriQuery/ .LINK https://github.com/tlindsay42/ArmorPowerShell/blob/master/Armor/Private/New-ArmorApiUriQuery.ps1 .LINK https://docs.armor.com/display/KBSS/Armor+API+Guide .LINK https://developer.armor.com/ #> [CmdletBinding()] [OutputType( [String] )] param ( # Specifies the query filters available to the endpoint.
