在powershell中使用工作流会话时命令消失

Question

在powershell中使用工作流会话时，大多数常见命令似乎都消失了：

PS P:> $session = New-PSWorkflowSession -ThrottleLimit 3
PS P:> Invoke-Command $session {Write-Output "test"}
The term 'Write-Output' is not recognized as the name of a cmdlet, function, script
file, or operable program. Check the spelling of the name, or if a path was included,
verify that the path is correct and try again.
 + CategoryInfo         : ObjectNotFound: (Write-Output:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException
+ PSComputerName        : localhost

如何使工作流中通常可用的所有常用命令在会话中可用？

Answer 1

由于您使用的是工作流会话，因此您需要将命令放入工作流中。

$session = New-PSWorkflowSession -ThrottleLimit 3
Invoke-Command $session {
        workflow test {
            Write-Output -Input "test"
        }
        test
    }
