## To run the script
# .\get_status.ps1 -Hostname <host> -Service_Action <action> -Service_Name <name>
#$Hostname = "hostname"
#$Service_Action = "Get-Service"
#$Service_Name = "service_name"
param(
[string]$Hostname,
[string]$Service_Action,
[string]$Service_Name
)
$ScriptBlockContent = {
param($Service_Action, $Service_Name)
& $Service_Action $Service_Name
}
# user credentials
$Username = "username"
$Password = "password"
# To avoid Manual entry of Username and Password
$Secure_String = convertto-securestring $Password -asplaintext -force
$User_cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $Username, $Secure_String
# Create a Session
$pso = New-PSSessionOption -NoMachineProfile
$sess = New-PSSession -ComputerName $Hostname -SessionOption $pso -credential $User_cred
#Run a powershell script in the session.
Invoke-Command -Session $sess -ScriptBlock $ScriptBlockContent -ArgumentList $Service_Action, $Service_Name
# Remove session
Remove-PSSession $sess
运行脚本:
.\<script_name>.ps1 -Hostname <host> -Service_Action <action> -Service_Name <name>
例如:服务行动是 - 获取服务,停止服务,启动服务 然后命名
Command: Get-Service Servicename
我收到错误: 这行代码中表达式或语句中出现意外的标记:
$ScriptBlockContent = {
param($Service_Action, $Service_Name)
$Service_Action $Service_Name # here is the error
}

您将命令作为字符串传递给函数,因此您在语法上对$Service_Action $Service_Name
执行的操作是在一行中引用两个字符串对象,而不需要任何操作符连接它们。这就是例外的原因。
告诉powershell,你想要将一个字符串作为命令执行,你有几个选择:
一种选择是将命令作为单个字符串传递给Invoke-Expression
cmdlet:
Invoke-Expression "$Service_Action $Service_Name"
或者你可以使用call-Operator &
,它也告诉powershell将命令视为字符串。在这种情况下,您不能在单个字符串中提供cmdlet和参数,而是在两个中:
& $Service_Action $Service_Name
