在 PowerShell 中通过 UDP 发送和接收数据

我正在尝试编写一个脚本来使用 PowerShell 进行测试和应用。测试应包括通过 UDP 向远程服务器发送字符串，然后读取该服务器的响应并对结果执行某些操作。我需要的唯一帮助是脚本的中间两个步骤（“发送字符串”，然后“接收响应”）：

1. 在端口 UDP 5000 上将字符串“ABCDEFG”发送到服务器 10.10.10.1
2. 接收来自服务器 10.10.10.1 的响应

我对 PowerShell 比较熟悉，但这是我第一次处理套接字，所以我处于陌生的领域，而且我似乎无法理解帖子中找到的几个示例。

不久前，我编写了一个简单的 PowerShell 脚本来发送 UDP 数据报。看：http://pshscripts.blogspot.co.uk/2008/12/send-udpdatagramps1.html http://pshscripts.blogspot.co.uk/2008/12/send-udpdatagramps1.html这会让你成功一半。不过我从来没有做过另一半并写过服务器端！

.SYNOPSIS 
    Sends a UDP datagram to a port 
.DESCRIPTION 
    This script used system.net.socckets to send a UDP 
    datagram to a particular port. Being UDP, there's 
    no way to determine if the UDP datagram actually 
    was received.  
    for this sample, a port was chosen (20000).

### 
#  Start of Script 
## 

# Define port and target IP address 
# Random here! 
[int] $Port = 20000 
$IP = "10.10.1.100" 
$Address = [system.net.IPAddress]::Parse($IP) 

# Create IP Endpoint 
$End = New-Object System.Net.IPEndPoint $address, $port 

# Create Socket 
$Saddrf   = [System.Net.Sockets.AddressFamily]::InterNetwork 
$Stype    = [System.Net.Sockets.SocketType]::Dgram 
$Ptype    = [System.Net.Sockets.ProtocolType]::UDP 
$Sock     = New-Object System.Net.Sockets.Socket $saddrf, $stype, $ptype 
$Sock.TTL = 26 

# Connect to socket 
$sock.Connect($end) 

# Create encoded buffer 
$Enc     = [System.Text.Encoding]::ASCII 
$Message = "Jerry Garcia Rocks`n"*10 
$Buffer  = $Enc.GetBytes($Message) 

# Send the buffer 
$Sent   = $Sock.Send($Buffer) 
"{0} characters sent to: {1} " -f $Sent,$IP 
"Message is:" 
$Message 
# End of Script
