![远程打开自定义远程 powershell](https://linux22.com/image/1342068/%E8%BF%9C%E7%A8%8B%E6%89%93%E5%BC%80%E8%87%AA%E5%AE%9A%E4%B9%89%E8%BF%9C%E7%A8%8B%20powershell.png)
我有 2 台计算机。在计算机 A 上,我有一个用 C# 为 powershell 3.0 编写的自定义模块,并通过 MSI 安装。我还有一个快捷方式,可以打开已加载模块的 powershell。
我可以双击我的快捷方式并在这台计算机上运行我的命令 Do-Something 而不会出现任何问题,就像 Exchange Server powershell 一样。
但现在我想用 C# 从计算机 B 上的远程会话来执行此操作。
所以我的问题是,如何在已加载模块并配置好 shell 的情况下打开到计算机 A 的远程 powershell 会话,以便我可以运行我的命令并获得与在计算机 A 上运行相同的结果?
答案1
我终于找到了实现我需要的方法。
首先我创建了一个 powershell 脚本来导入我的模块和模块脚本文件
ShellInitScript
function Get-ScriptDirectory
{
$Invocation = (Get-Variable MyInvocation -Scope 1).Value
Split-Path $Invocation.MyCommand.Path
}
$MyModuleDirectory = Get-ScriptDirectory
Set-Location $MyModuleDirectory
Import-Module .\MyModule.psd1
我的模块.psd1
@{
GUID = "[GENERATE A GUID HERE]" # Generate using $myGuid = [guid]::NewGuid()
Author = "Me"
CompanyName = "My Company"
Copyright = "© My Company. All rights reserved."
ModuleVersion = "1.0.0.0"
ModuleToProcess = "MyModule.psm1"
}
我的模块.psm1
Import-Module .\MyModuleCSharpAssembly.dll
function Enable-MyShellRemoting([switch]$Force)
{
$proceed = 0
if($Force -eq $false)
{
Write-Warning "Enable-MyShellRemoting restarts the WinRM service and all dependent services.`r`nAll WinRM sessions connected to Windows PowerShell session configurations are disconnected."
$title = "Are you sure you want to perform this action?"
$message = "Performing this operation will allow selected users to remotely run MyModule commands on this computer."
$yes = New-Object System.Management.Automation.Host.ChoiceDescription "&Yes"
$no = New-Object System.Management.Automation.Host.ChoiceDescription "&No"
$options = [System.Management.Automation.Host.ChoiceDescription[]]($yes, $no)
$proceed = $Host.UI.PromptForChoice($title, $message, $options, 0)
}
if($proceed -eq 0)
{
Enable-PSRemoting -Force
if((Get-WmiObject Win32_ComputerSystem).PartOfDomain -eq $false){
Set-Item WSMan:\localhost\Client\TrustedHosts *
Restart-Service WinRM
}
$path = Join-Path -Path $MyModuleDirectory -ChildPath "ShellInitScript.ps1"
Register-PSSessionConfiguration -Name "MyShellUri" -StartupScript $path -Force
}
}
function Disable-MyShellRemoting([switch]$Force, [switch]$DisablePSRemoting)
{
$proceed = 0
if($Force -eq $false)
{
Write-Warning "Disable-MyShellRemoting restarts the WinRM service and all dependent services.`r`nAll WinRM sessions connected to Windows PowerShell session configurations are disconnected."
$title = "Are you sure you want to perform this action?"
$message = "Performing this operation will prevent all users to remotely run MyModule commands on this computer.`r`nUse the the -DisablePSRemoting switch to disable all PowerShell remoting features."
$yes = New-Object System.Management.Automation.Host.ChoiceDescription "&Yes"
$no = New-Object System.Management.Automation.Host.ChoiceDescription "&No"
$options = [System.Management.Automation.Host.ChoiceDescription[]]($yes, $no)
$proceed = $Host.UI.PromptForChoice($title, $message, $options, 0)
}
if($proceed -eq 0)
{
if($DisablePSRemoting)
{
Disable-PSRemoting
}
if((Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue) -eq $null){
Write-Host "The session configuration MyShellUri is already unregistered."
}
else {
Unregister-PSSessionConfiguration -Name "MyShellUri" -Force -ErrorAction Ignore
}
}
}
function Test-MyShellRemote()
{
return "Test completed"
}
dll MyModuleCSharpAssembly.dll 只是一个包含自定义 Cmdlet 的常规 .Net 程序集。
问题的解决方案是在函数 Enable-MyShellRemoting 中,此方法启用 powershell 远程处理并使用加载模块的启动脚本注册自定义 Powershell 会话配置。
然后在 C# 中我们要做的就是在连接对象中指定 ShellUri,如下所示
WSManConnectionInfo connectionInfo = new WSManConnectionInfo();
connectionInfo.ComputerName = "MyComputer";
connectionInfo.ShellUri = "http://schemas.microsoft.com/powershell/MyShellUri";
using (Runspace remoteRunspace = RunspaceFactory.CreateRunspace(connectionInfo))
{
remoteRunspace.Open();
using (PowerShell shell = PowerShell.Create())
{
shell.Runspace = remoteRunspace;
shell.AddCommand("Test-MyShellRemote");
Collection<PSObject> results = shell.Invoke();
//the results collection contains the string return by the command
}
remoteRunspace.Close();
}
