Как заявлено @OcasoProtal, вы можете сравнить массив действительных статусов с вашим целевым статусом, используя операторы -contains
или -notcontains
.
Данный статус основан на типе перечисления, вы также можете использовать это(то есть в отличие от использования сравнения строк).Это добавляет дополнительную проверку (т. Е. Без указания вручную ValidateSet) и позволяет получить список значений из Enum (например, как показано в моем примере кода ниже, где указано Not
.
clear-host
[string]$ComputerName = $env:COMPUTERNAME
[string]$ServiceName = "MSSQLSERVER"
function Wait-ServiceStatus {
[CmdletBinding()]
param
(
[Parameter(Mandatory = $true)]
[ValidateNotNullOrEmpty()]
[string]$ServiceName
,
[Parameter()]
[ValidateNotNullOrEmpty()]
[string]$ComputerName = $env:COMPUTERNAME
,
[switch]$Not
,
[Parameter(Mandatory = $true)]
[System.ServiceProcess.ServiceControllerStatus]$TartgetStatus
)
begin {
[System.ServiceProcess.ServiceControllerStatus[]]$TargetStatuses = @($TartgetStatus)
if ($Not.IsPresent) {
#EXAMPLE: Build your comparison array direct from the ENUM
$TargetStatuses = [Enum]::GetValues([System.ServiceProcess.ServiceControllerStatus]) | ?{$_ -ne $TartgetStatus}
}
}
process {
#EXAMPLE: Compare status against an array of statuses
while ($TargetStatuses -notcontains (Get-Service -ComputerName $ComputerName -Name $ServiceName | Select -Expand Status)) {
write-host "." -NoNewline -ForegroundColor Red
start-sleep -seconds 1
}
write-host ""
#this is a demo of array of statuses, so won't bother adding code for timeouts / etc
}
}
function Write-InfoToHost ($text) {write-host $text -ForegroundColor cyan} #quick thing to make our status updates distinct from function call output
Write-InfoToHost "Report Current Service Status"
get-service -Name $ServiceName -Computer $ComputerName | Select -ExpandProperty Status
Write-InfoToHost ("Stop Service at {0:HH:mm:ss}" -f (get-date))
(Get-WmiObject Win32_Service -Filter "name='$ServiceName'" -Computer $ComputerName).StopService() | out-null #use WMI to prevent waiting
Write-InfoToHost ("Invoked Stop Service at {0:HH:mm:ss}" -f (get-date))
Wait-ServiceStatus -ServiceName $ServiceName -TartgetStatus Stopped
Write-InfoToHost ("Stop Service Completed at {0:HH:mm:ss}" -f (get-date))
Write-InfoToHost "Report Current Service Status"
get-service -Name $ServiceName -Computer $ComputerName | Select -ExpandProperty Status
Write-InfoToHost ("Start Service at {0:HH:mm:ss}" -f (get-date))
(Get-WmiObject Win32_Service -Filter "name='$ServiceName'" -Computer $ComputerName).StartService() | out-null #use WMI to prevent waiting
Write-InfoToHost ("Invoked Start Service at {0:HH:mm:ss}" -f (get-date))
Wait-ServiceStatus -ServiceName $ServiceName -Not -TartgetStatus Stopped
Write-InfoToHost ("Service Not Stopped at {0:HH:mm:ss}" -f (get-date))
Wait-ServiceStatus -ServiceName $ServiceName -Not -TartgetStatus StartPending
Write-InfoToHost ("Service Not Start-Pending at {0:HH:mm:ss}" -f (get-date))
Write-InfoToHost "Report Current Service Status"
get-service -Name $ServiceName -Computer $ComputerName | Select -ExpandProperty Status
Пример вывода:
Report Current Service Status
Running
Stop Service at 12:04:49
Invoked Stop Service at 12:04:50
.
Stop Service Completed at 12:04:51
Report Current Service Status
Stopped
Start Service at 12:04:51
Invoked Start Service at 12:04:52
Service Not Stopped at 12:04:52
..
Service Not Start-Pending at 12:04:54
Report Current Service Status
Running
Вы также можете легко получить статусы Ожидание или «Стабильное состояние», используя что-то вроде этого:
function PendingDemo([bool]$Pending) {
write-host "Pending is $Pending" -ForegroundColor cyan
[Enum]::GetValues([System.ServiceProcess.ServiceControllerStatus]) | ?{($_ -notlike "*Pending") -xor $Pending}
}
PendingDemo $true
""
PendingDemo $false
Пример вывода:
Pending is True
StartPending
StopPending
ContinuePending
PausePending
Pending is False
Stopped
Running
Paused
