在 PowerShell 中通过 UDP 发送和接收数据 [英] Send and Receive data via UDP in PowerShell

问题描述

我正在尝试编写脚本以使用 PowerShell 进行测试和应用程序.测试应该包括通过 UDP 向远程服务器发送一个字符串，然后从该服务器读取响应并使用结果做一些事情.我需要的唯一帮助是脚本的中间两个步骤(发送字符串"，然后是接收响应"):

1. 在端口 UDP 5000 上将字符串ABCDEFG"发送到服务器 10.10.10.1
2. 从服务器 10.10.10.1 接收响应

我对 PowerShell 比较熟悉，但这是我第一次不得不处理套接字，所以我在陌生的水域，我似乎无法理解我在帖子中找到的几个例子.

解决方案

前段时间，我编写了一个简单的 PowerShell 脚本来发送 UDP 数据报.请参阅:http://pshscripts.blogspot.co.uk/2008/12/send-udpdatagramps1.html 这会让你成功.我从来没有做过另一半，也没有写过这个的服务器端！

I am trying to write a script to test and application using PowerShell. The test should consist of sending a string to a remote server over UDP, then reading the response from that server and doing something with the result. The only help I need is with the middle two ('send string', then 'receive response') steps of the script:

1. Send string "ABCDEFG" to server 10.10.10.1 on port UDP 5000
2. Receive response from server 10.10.10.1

I am relatively familiar with PowerShell, but this is my first time having to deal with sockets, so I am in unfamiliar waters, and I can't seem to make sense of the few examples I have found on posts.

解决方案

Some time back, I wrote a simple PowerShell script to send a UDP Datagram. See: http://pshscripts.blogspot.co.uk/2008/12/send-udpdatagramps1.html which will get you half way there. I never did do the other half and write the server side of this though!

<#  
.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
