Question

我需要从 excel 文件的长列表中创建新的防火墙规则。为此，我将使用 PowerShell 和 ImportExcel 模块。考虑到我不熟悉 Windows 和 PowerShell，我需要帮助了解如何实际执行此操作。

excel 的第一列代表 IpAndPorts，我需要阻止并添加为防火墙规则。我需要从“第 2 行”获取数据，直到 excel 数据结束。

这里是excel的例子：

<头>

Excel-Row	IpAndPorts	协议
2	35.180.0.0/16	TCP
3	12.13.14.1/8883,433	TCP
4	1.2.3.4/80	HTTP

我还需要将 New-NetFirewallRule 命令中的 -DisplayName & -Name 设为动态，以便稍后我可以找到防火墙规则（一些代码示例）。

我将在 PowerShell 中用于创建防火墙规则的命令：

New-NetFirewallRule -DisplayName "Block WiFi {Excel-Row}" -Name "Block Wifi {Excel-Row}" -Direction Inbound -InterfaceType Wireless -Action Block -RemoteAddress {Part before / IpAndPorts} -LocalPort {Part after / IpAndPorts} -Protocol {Protocol}

从 Excel 中获取第 3 行数据后的命令示例：

New-NetFirewallRule -DisplayName "Block WiFi 3" -Name "Block Wifi 3" -Direction Inbound -InterfaceType Wireless -Action Block -RemoteAddress 12.13。 14.1 -LocalPort 8883,433 -Protocol TCP

更新： 这是我设法编写的代码：

# ---------------------------------------
# Here we should get data from excel
# and prepare variables

$FirewallList = Import-Excel C:\Temp\list.xlsx
$All = $FirewallList.IpAndPorts
$AllProtocols = $FirewallList.Protocol

# ---------------------------------------
# Here it should be number of excel row, 
# starting from 2 and incementing until last data in row
# Don't know how to do that

$Index = "1"

# ---------------------------------------
# Split IpAndPorts data to get IP and PORT

$Ip = $All.Split("/")[0]
$Port = $All.Split("/")[1]

# ---------------------------------------
# Here we should populate parameters

#$Params = @{ 
#    "DisplayName" = 'Block-WiFi-' + $Index  
#    "Name" = 'Block-WiFi-' + $Index 
#    "Direction" = 'Inbound' 
#    "InterfaceType" = 'Wireless'
#    "Action" = 'Block'
#    "RemoteAddress" = $Ip
#    "LocalPort" = $Port
#    "Protocol" = $AllProtocols
#}

# Here we should start the command
# New-NetFirewallRule @Params

# ---------------------------------------
# Test how the command will be assembled 
# based on data from excel

$Test = New-Object PSObject -Property @{
    DisplayName = "Block-WiFi-" + $Index  
    Name = "Block-WiFi-" + $Index 
    Direction = 'Inbound' 
    InterfaceType = 'Wireless'
    Action = 'Block'
    RemoteAddress = $Ip
    LocalPort = $Port
    Protocol = $AllProtocols
}

Write-Host "New-NetFirewallRule
-DisplayName $($Test.DisplayName)
-Name $($Test.Name)
-Direction $($Test.Direction) 
-InterfaceType $($Test.InterfaceType)
-Action $($Test.Action)
-RemoteAddress $($Test.RemoteAddress)
-LocalPort $($Test.LocalPort)
-Protocol $($Test.Protocol)
"
# Test results. Just printing
Write-Host "------------- PRINT FROM EXCEL ----------------"
$All
$AllProtocols
Write-Host "---------------------------------------------"
$Ip
$Port

如何使循环从 excel 中获取每个值，添加到 $Params 中并执行命令？

加载 Excel 文件时

rst.Open mySQL, cnt, adOpenDynamic, adLockBatchOptimistic

尝试执行 $FirewallList = Import-Excel C:\Temp\list.xlsx $All = $FirewallList.IpAndPorts $AllProtocols = $FirewallList.Protocol - 这是行数。

然后您可以通过更改 $FirewallList.Count 中的 i（从 0 开始）来访问每一行，对于上面的其他变量也是如此。

例如：

$FirewallList[i]

您也可以使用 foreach 循环遍历所有元素。
