我似乎在Invoke-Command
中获取变量时出现问题。无论我做什么,我都无法获得变量。当我想使用时:
Invoke-Command -ComputerName $servername { new-item -Path "$RootPathDestination" -Name $version -Itemtype directory }
我收到错误:
Cannot bind argument to parameter 'Path' because it is an empty string.
我在这个剧本中声明了它们:
$version = 36
$RootPathDestination = "c:\scripts\"
有没有人有任何想法?我真的没有选择: - (
$svr = "SQLSERVER"
$db = "0000 - INFRA"
$version = 36
$RootPathDestination = "c:\scripts\"
# connection
$sqlConnection = New-Object System.Data.SqlClient.SqlConnection
$sqlConnection.ConnectionString = "Server=$svr;Database=$db;Integrated Security=True"
$sqlConnection.Open()
$cmd = $sqlConnection.CreateCommand()
$cmd.CommandText ="SELECT * from infrastructure"
$Serverinfo = $cmd.ExecuteReader()
try
{
while ($Serverinfo.Read())
{
$servername = $Serverinfo.GetValue(1)
Invoke-Command -ComputerName $servername { new-item -Path "$RootPathDestination" -Name $version -Itemtype directory }
#Invoke-Command -ComputerName $servername { Copy-Item c:\scripts\* c:\test }
#Invoke-Command -ComputerName $servername {Import-Module WebAdministration ; New-WebApplication -force -Site "Default Web Site" -Name 3.78 -PhysicalPath "c:\inetpub\"$version }
}
}
catch
{
echo "Hmm strange"
}
finally
{
echo "All good!"
echo $Version
$sqlConnection.Close()
}

您必须使用使用前缀:
Invoke-Command -ComputerName $servername { new-item -Path "$using:RootPathDestination" -Name $using:version -Itemtype directory }

您正在将脚本块传递给Invoke-Command
。为了使用脚本块中
