powershell - 如何创建强制端口进入监听状态以测试 PowerShell 功能的服务？

Question

已创建 PowerShell 脚本以创建服务。其中一个片段测试服务是否正在运行以及与该服务关联的端口监听:

if (($serviceStatus.Status -eq "running") -and (Get-StatePort)) {
    Write-Host "$packageName service has been started"
    return
} else {
    Write-Host "$packageName service cannot be started. Attempt $i to start the service."
}

testService.bat

ping localhost

创建服务

nssm install installServiceTest "C:\testService.bat" 创建一个服务:

PS C:\> Get-WmiObject -Class Win32_Service -Filter "Name='installServiceTest'"

ExitCode  : 0
Name      : installServiceTest
ProcessId : 5288
StartMode : Auto
State     : Running
Status    : OK

服务运行，但下一步是扩展脚本以分配端口并强制其进入监听状态。

例如脚本启动后，端口 9999 应该会监听。

PS C:\> Get-NetTCPConnection -State Listen | Where-Object {$_.LocalAddress -match "::|0.0.0.0" -and $_.LocalPort -eq "9999"}
PS C:\>

您可以添加以下内容:

$port=9999
$IPendpoint = new-object System.Net.IPEndPoint ([system.net.ipaddress]::any, $port)
$listener = new-object System.Net.Sockets.TcpListener $IPendpoint
$listener.start()
$client = $listener.AcceptTcpClient()

然后在另一个窗口:

Get-NetTCPConnection -State Listen | Where-Object {$_.LocalAddress -match "::|0.0.0.0" -and $_.LocalPort -eq "9999"}

LocalAddress                        LocalPort RemoteAddress                       RemotePort State       AppliedSetting
------------                        --------- -------------                       ---------- -----       --------------
0.0.0.0                             9999      0.0.0.0                             0          Listen
