无法使用PowerShell在任务计划程序中创建任务

我正在尝试使用Powershell在任务计划程序中创建任务

$PSVersionTable.PSVersion Major Minor Build Revision ----- ----- ----- -------- 3 0 -1 -1

schu task\u action.conf的内容

：

New-ScheduledTaskAction -Execute c:\windump\windump.exe –Argument "-i 1 -q -w e:\network-dump\Network-Traces.txt -n -C 100 -W 100 -U -n ip and not net 125.14.93.7 and not net 10.0.2.4"

尝试运行PowerShell脚本时，出现以下错误：

Register-ScheduledTask : Cannot process argument transformation on parameter 'Action'. Cannot convert value "New-ScheduledTaskAction -Execute C:\windump\windump.exe –Argument "-i 1 -q -w E:\network-dump\Network-Traces.txt -n -C 100 -W 100 -U -n ip and not net 125.14.93.7 and not net 10.0.2.4" " to type "Microsoft.Management.Infrastructure.CimInstance[]".

我花了几个小时试图通过在线搜索找出答案，但没有结果。

获取内容-Raw

返回一个字符串，PowerShell不会解释该字符串，并且无法按原样传递给参数

-Action

。从

schu task\u action\u final.conf

中删除

New ScheduledTaskAction-Execute

和

-Argument

，然后更改

$sch_task_action = Get-Content c:\automation\sch_task_action_final.conf -Raw

到

或者，您可以使用

调用表达式

：

$sch_task_action = Invoke-Expresssion (Get-Content c:\automation\sch_task_action_final.conf -Raw)

---

但我不建议这样做。

您可以使用COM对象创建计划任务。使用Schedule.Service，您可以创建它：

                $service = new-object -ComObject("Schedule.Service")
                # connect to the local machine.

                $service.Connect()
                $rootFolder = $service.GetFolder("\")
                $TaskDefinition = $service.NewTask(0)
                $TaskDefinition.RegistrationInfo.Description = "$TaskDescr"
                $TaskDefinition.Settings.Enabled = $true
                $TaskDefinition.Settings.AllowDemandStart = $true
                $TaskDefinition.Settings.StartWhenAvailable = $true
                $TaskDefinition.Settings.StopIfGoingOnBatteries=$false
                $TaskDefinition.Settings.DisallowStartIfOnBatteries=$false
                $TaskDefinition.Settings.MultipleInstances=2
                $taskdefinition.Settings.WakeToRun=$true
                $triggers = $TaskDefinition.Triggers
                $trigger = $triggers.Create(1) # Creates a "One time" trigger
                $trigger.StartBoundary = $TaskStartTime.ToString("yyyy-MM-dd'T'HH:mm:ss")
                $time_interval=New-TimeSpan -Minutes $interval
                $time_interval=$time_interval.TotalSeconds
                $trigger.Repetition.Interval= "PT"+"$time_interval"+"S"
                $trigger.Enabled = $true
                $TaskDefinition.Principal.RunLevel =1
                $Action = $TaskDefinition.Actions.Create(0)
                $action.Path = "$TaskCommand"
                $action.Arguments = "$TaskArg"
                # In Task Definition,
                #   6 indicates "the task will not execute when it is registered unless a time-based trigger causes it to execute on registration."
                #   5 indicates "Indicates that a Local System, Local Service, or Network Service account is being used as a security context to run the task.In this case, its the SYSTEM"
                $rootFolder.RegisterTaskDefinition("$TaskName",$TaskDefinition,6,"System",$null,5) | Out-Null
                "Scheduled Task has been created successfully"
                Write-Log -Message "Scheduled Task has been created successfully with the name SHA_$schedule_name" -Level Info

希望能有所帮助。

你的建议很有效。非常感谢您的解释。：）顺便说一句，当我在寻找解决方案时，我也遇到了这个命令：

$sch_task_action=[IO.File]：:ReadAllText（“C:\automation\sch_task_action_final.conf”）

，但同样的错误也导致了失败。知道为什么吗？因为它与

获取内容-Raw

的功能相同。谢谢，但实际上我一直在寻找脚本失败的原因。@Technext:我看到Ansgar已经给出了很好的解释……我的目的是给出另一条出路。：）

$action, $params = (Get-Content C:\automation\sch_task_action_final.conf -Raw) -split ' ', 2
$sch_task_action = New-ScheduledTaskAction -Execute $action -Arugment $params

$sch_task_action = Invoke-Expresssion (Get-Content c:\automation\sch_task_action_final.conf -Raw)

                $service = new-object -ComObject("Schedule.Service")
                # connect to the local machine.

                $service.Connect()
                $rootFolder = $service.GetFolder("\")
                $TaskDefinition = $service.NewTask(0)
                $TaskDefinition.RegistrationInfo.Description = "$TaskDescr"
                $TaskDefinition.Settings.Enabled = $true
