PowerShell TCP 服务器

I would like to ask you, how it is possible to handle multiple connection threads.I have implemented TCP server in the following way:$endpoint = New-Object System.Net.IPEndPoint ([System.Net.IPAddress]::Any, 8989)$listener = New-Object System.Net.Sockets.TcpListener $endpoint$listener.Start()do { $client = $listener.AcceptTcpClient() # will block here until connection $stream = $client.GetStream(); $reader = New-Object System.IO.StreamReader $stream do { $line = $reader.ReadLine() Write-Host $line -fore cyan } while ($line -and $line -ne ([char]4)) $reader.Dispose() $stream.Dispose() $client.Dispose()} while ($line -ne ([char]4))$listener.Stop()This code can handle just one thread in time.Can you give me an advice on how to create a TCP server in PowerShell that can handle multiple clients? 解决方案 For handling multiple clients you need multiple threads and for that you need to use runspaces. Below is the working code which accepts multiple clients and do the processing of each client in separate thread (runspace)$Global:Listener = [HashTable]::Synchronized(@{})$Global:CnQueue = [System.Collections.Queue]::Synchronized((New-Object System.collections.queue))$Global:space = [RunSpaceFactory]::CreateRunspace()$space.Open()$space.SessionStateProxy.setVariable("CnQueue", $CnQueue)$space.SessionStateProxy.setVariable("Listener", $Listener)$Global:newPowerShell = [PowerShell]::Create()$newPowerShell.Runspace = $space$Timer = New-Object Timers.Timer$Timer.Enabled = $true$Timer.Interval = 1000Register-ObjectEvent -SourceIdentifier MonitorClientConnection -InputObject $Timer -EventName Elapsed -Action { While($CnQueue.count -ne 0) { $client = $CnQueue.Dequeue() $newRunspace = [RunSpaceFactory]::CreateRunspace() $newRunspace.Open() $newRunspace.SessionStateProxy.setVariable("client", $client) $newPowerShell = [PowerShell]::Create() $newPowerShell.Runspace = $newRunspace $process = { $stream = $client.GetStream(); $reader = New-Object System.IO.StreamReader $stream [console]::WriteLine("Inside Processing") # You have client here so do whatever you want to do here. # This is a separate thread so if you write blocking code here, it will not impact any other part of the program } $jobHandle = $newPowerShell.AddScript($process).BeginInvoke() #jobHandle you need to save for future to cleanup }}$listener = { $Listener['listener'] = New-Object System.Net.Sockets.TcpListener("127.0.0.1", "1234") $Listener['listener'].Start() [console]::WriteLine("Listening on :1234") while ($true) { $c = $Listener['listener'].AcceptTcpClient() If($c -ne $Null) { [console]::WriteLine("{0} >> Accepted Client " -f (Get - Date).ToString()) $CnQueue.Enqueue($c) } Else { [console]::WriteLine("Shutting down") Break } }}$Timer.Start()$Global:handle = $newPowerShell.AddScript($listener).BeginInvoke()For more detailed example please go here 这篇关于PowerShell TCP 服务器的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
