Powershell v2 | 脚本无法声明变量，需要帮助调试

Question

好的，似乎脚本有几个问题，我无法解决其中任何一个，还希望能对脚本进行一些反馈。这仍然是我的第一个脚本，所以可能需要很多小调整，请告诉我您想到的任何建议。

问题：大部分问题都围绕着日志记录。

1. 没有检查日志文件，因此脚本会一遍又一遍地将计算机添加到日志文件中。

2. 日志文件不更新生成的信息，例如操作系统、mac、ip等。

显示的问题：

无法在此对象上找到属性“Result”。确保它存在。位于 W:\Powershell Scripting\Test Lab\TestFunction.ps1:86 字符:17 + IF ($Computer. <<<< Result -ne "Successful") { + CategoryInfo : InvalidOperation: (.:OperatorToken) [], RuntimeException + FullyQualifiedErrorId : PropertyNotFoundStrict

脚本：

Set-PSDebug -strict
Set-StrictMode -Version latest
$consoleObject = (Get-Host).UI.RawUI

# Adjustable Variables
$Computers_Path = ".\computers.txt"
$Log_Path = ".\Log.txt"

代码太多了。你可能想要减少样本的数量，使其小到可以轻松地再现出你所遇到的问题。 - Victor Zakharov

Answer 1

这次的问题是您在$Computers集合成员中没有Result成员，只有Name和MAC。除非您稍后在代码中添加此成员，但我不想阅读它，因为它已经有大约100行，并且包含与实际问题陈述无关的很多代码。

$Computers = @(Import-CSV $Computers_Path -header "Name","MAC")

你尝试过在Powershell ISE上调试脚本吗？它是Powershell 2的内置调试器。可以看一下Technet文章了解更多信息。

作为 PS ISE 的替代方案，您可以使用 PowerGUI 脚本编辑器进行调试。它在 v2 上运行良好。 - Victor Zakharov

Answer 2

这是关于 $Computers 集合的声明...

$Computers = @(Import-CSV $Computers_Path -header "Name","MAC")

...在这种情况下无法工作：

IF ($Computer.Result -ne "Successful")

异常消息明确指出了问题所在：

对象上找不到属性'Result'。请确保该属性存在。\TestFunction.ps1:86 char:17

为解决此问题，建议初始化Result属性，可能需要这样做：

$Computers = @(Import-CSV $Computers_Path -header "Name","MAC","Result")
