我正在尝试从 Server-2 对 Server-1（即远程服务器）执行以下 PowerShell 脚本：

$DBServer = 'Server1' 

Invoke-Command -ComputerName $DBServer -ScriptBlock {
$status = Start-Process "C:\Program Files\iQ4bis\HaloSource\HaloSource.Run.exe" '"D:\Test\UsageTracking.iqp" /wf "Default Workflow" /e "Dev" ' -Wait -PassThru
$test2 = $status.ExitCode
if ($test2 -ne 0) 
{ 
    Throw "The command exited with error code: $test2"
}
else
{
    Write-host "Workflow executed successfully."    
}
}

问题：代码部分

"C:\Program Files\iQ4bis\HaloSource\HaloSource.Run.exe" '"D:\Test\UsageTracking.iqp" /wf "Default Workflow" /e "Dev" ' -Wait -PassThru

我想让它参数化，作为每个项目的值D:\Test\UsageTracking.iqp并且Dev将改变。如何使用参数传入新值？如果可能的话，这就是我想要的方式：

clear-host

$DBServer = 'Server1'
$v1 = 'D:\Test\UsageTracking.iqp'
$v2 = 'Dev'
$v3 = "C:\Program Files\iQ4bis\HaloSource\HaloSource.Run.exe"

Invoke-Command -ComputerName $DBServer -ScriptBlock {
param(
[string] $IQPFileDestinationLocation = $v1, [string] $ExecutionEnvironment = $v2, [string] $exe = $v3
)

$IQPFileLocation = $IQPFileDestinationLocation
$workflow = "Default Workflow"
$environment = $ExecutionEnvironment
$test = """$exe"" '""$IQPFileLocation"" /wf ""$workflow"" /e ""$environment""'"
$test

$status = Start-Process $test -Wait -PassThru

$test2 = $status.ExitCode
if ($test2 -ne 0) 
{ 
    Throw "The command exited with error code: $test2"
}
else
{
    Write-host "It went ok."    
}

} -ArgumentList $v1 ,$v2 ,$v3

当我在上面运行时，我收到以下错误消息：

    This command cannot be run due to the error: The system cannot find the file specified.
    + CategoryInfo          : InvalidOperation: (:) [Start-Process], InvalidOperationException
    + FullyQualifiedErrorId : InvalidOperationException,Microsoft.PowerShell.Commands.StartProcessCommand
    + PSComputerName        : ken-dev-bi001

The command exited with error code: 
At line:8 char:1
+ Invoke-Command -ComputerName $DBServer -ScriptBlock {
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : OperationStopped: (The command exited with error code: :String) [], RuntimeException
    + FullyQualifiedErrorId : The command exited with error code:

任何帮助都会让它工作。

我不会实现您的代码，但会通过一个简单的示例进行解释，以便您可以相应地实现它。

假设您需要启动一个托管在 IIS 上的网站。我已经声明了变量。在函数中，你可以为变量赋值，它应该是这样的，而不是 $args[0]，它应该是 $abc，但是我已经分配了变量运行时的值。您还可以通过用逗号分隔多个值来分配多个值，例如

-ScriptBlock {Start-Website $args[0] $args[1]} -ArgumentList $xyz, $abc

Code Snippet

   $User="UserName"
   $Password="password"
   $abc="MyWebsite"
   $xyz="MyWebsite2"
   $ComputerName = "MyComputerName"
   $pword = ConvertTo-SecureString -String $Password -AsPlainText -Force
   $credential = New-Object -TypeName "System.Management.Automation.PSCredential" -ArgumentList $User, $pword

   function StartIIS($abc)
   { 
     Invoke-Command -ComputerName $ComputerName -Credential $credential -ScriptBlock {Start-Website $args[0]} ArgumentList $abc
   }  

   StartIIS($abc)

所有，
所以，最后我想出了如何在与远程服务器-ScriptBlock一起使用时将局部变量传递给。这是我使用的代码，它就像一个魅力：Invoke-Command

Write-Host "Workflow command was: "$HaloSourceCommandLine

Invoke-Command -ComputerName $DBServer -ScriptBlock {
param ([string] $t1 = $HaloSourceCommandLine, [string] $t2 = $HaloSourceExecutableLocation)

    $status = Start-Process $t2 $t1 -Wait -PassThru
    $ExitCodeInfo = $status.ExitCode
        if ($ExitCodeInfo -ne 0) 
        { 
            Throw "The command exited with error code: $test2"
        }
        else
        {
            Write-host "Workflow executed successfully."    
        }
} -ArgumentList $HaloSourceCommandLine,$HaloSourceExecutableLocation

如果他们在-ScriptBlock通过远程服务器执行时遇到问题，希望这对其他人有帮助Invoke-Command

谢谢，惠普
