运行并处理来自ps1脚本的输出
问题描述:
目标:从系统获取所有登录/注销的用户。 那些通过使用远程桌面连接登录/注销的用户。运行并处理来自ps1脚本的输出
我的脚本:
Param(
[array]$ServersToQuery = (hostname),
[datetime]$StartTime = "January 1, 1970"
)
foreach ($Server in $ServersToQuery) {
$LogFilter = @{
LogName = 'Microsoft-Windows-TerminalServices-LocalSessionManager/Operational'
ID = 21, 23, 24, 25
StartTime = $StartTime
}
$AllEntries = Get-WinEvent -FilterHashtable $LogFilter -ComputerName $Server
$AllEntries | Foreach {
$entry = [xml]$_.ToXml()
[array]$Output += New-Object PSObject -Property @{
TimeCreated = $_.TimeCreated
User = $entry.Event.UserData.EventXML.User
IPAddress = $entry.Event.UserData.EventXML.Address
EventID = $entry.Event.System.EventID
ServerName = $Server
}
}
}
$FilteredOutput += $Output | Select TimeCreated, User, ServerName, IPAddress, @{Name='Action';Expression={
if ($_.EventID -eq '21'){"logon"}
if ($_.EventID -eq '22'){"Shell start"}
if ($_.EventID -eq '23'){"logoff"}
if ($_.EventID -eq '24'){"disconnected"}
if ($_.EventID -eq '25'){"reconnection"}
}
}
$Date = (Get-Date -Format s) -replace ":", "."
$FilePath = "$env:USERPROFILE\Desktop\$Date`_RDP_Report.csv"
$FilteredOutput | Sort TimeCreated | Export-Csv $FilePath -NoTypeInformation
Write-host "Writing File: $FilePath" -ForegroundColor Cyan
Write-host "Done!" -ForegroundColor Cyan
#End
我真的不明白PS1脚本。我发现这个脚本,但我想用它来达到我的目的。
当我尝试用C#来执行它:
方案1:
string scriptText = "C:\\MyPath\\script.ps1";
try
{
Runspace runspace = RunspaceFactory.CreateRunspace();
// open it
runspace.Open();
// create a pipeline and feed it the script text
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(scriptText);
Collection<PSObject> results = pipeline.Invoke();
它抛出一个错误:
PS1没有数字签名。
第二种情况:
using (PowerShell PowerShellInstance = PowerShell.Create())
{
PowerShellInstance.AddScript(str_Path);
Collection<PSObject> PSOutput = PowerShellInstance.Invoke();
if (PowerShellInstance.Streams.Error.Count > 0)
{
// error records were written to the error stream.
// do something with the items found.
}
}
流总是空的。实际上它总是数0行。
任何想法/建议如何做到这一点?
