Question

我有一个脚本，需要通过远程传递脚本中的凭据，如下所示：-

$UserName = Read-Host "Enter User Name:" 
$Password = Read-Host -AsSecureString "Enter Your Password:" 
$Credential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $UserName , $Password 


Set-Service -Name HiTrust -StartupType Automatic -ComputerName ServerName -credential $Credential 
(Get-Service  -Name "HiTrust" -credential $Credential -ComputerName ServerName).Start() 
Exit

但是我仍然遇到如下错误：-

Set-Service : A positional parameter cannot be found that accepts argument 'System.Management.Automation.PSCredential'.
At C:\Users\ucub\Desktop\Test.ps1:9 char:15
+ ...             Set-Service -Name HiTrust -StartupType Automatic -Compute ...
+                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [Set-Service], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.SetServiceCommand

Answer 1

问题在于，设置服务没有凭据参数。看here

尝试这样的事情：

Enter-PSSession -ComputerName $computername -Credential $credentials
Set-Service -Name HiTrust -StartupType Automatic

或

Invoke-Command -ComputerName $computername -Credential $credential -ScriptBlock {Set-Service -Name HiTrust -StartupType Automatic}

Answer 2

如果您使用的是此PSVersion及更低版本，这是您在Set-Service上失败的根本原因...

$PSVersionTable.PSVersion

您也不需要脚本中的内容。

我建议重构

(Get-Command -Name Invoke-Command).Parameters.Keys
# Results
Session

$ServerName = Read-Host 'Enter a target server name:' 
$ServiceName = Read-Host 'Enter a target service name:' 
Invoke-Command -ComputerName $ServerName -ScriptBlock {
    "Executing service actions on $env:COMPUTERNAME"
    Set-Service -Name $ServiceName -StartupType Automatic
    Start-Service -Name $ServiceName
} -Credential (Get-Credential -Credential "$env:USERDOMAIN\$env:USERNAME")

找不到接受参数-System.Management.Automation.PSCredential'-Error的位置参数
