echoo00 思路：
通过 PowerShell 实现一个函数来维护操作的逻辑。
1. 读取特定路径的 domain.txt 来管理规则
2. 实现 Add 操作的逻辑，NRPT 规则不存在则添加
3. 实现 Add 操作的逻辑，NRPT 规则存在则更新
4. 实现 Add 操作的逻辑，NRPT 规则多余则删除
5. 实现 Clean 操作的逻辑，清理本机所有 NRPT 规则，恢复初始状态。
代码如下:
```powershell
param (
[string]$Action = "Add", # 可以是 Add 或 Clean
[string]$FilePath = ".\domains.txt", # 包含域名的文件路径
[string]$NameServer = "192.168.188.2" # 默认的 DNS 服务器地址
)
function Manage-NrptRuleFromFile {
param (
[string]$Action,
[string]$FilePath,
[string]$NameServer
)
# 读取文件中的域名，添加前缀 '.'
$fileNamespaces = Get-Content $FilePath | ForEach-Object { "." + $_ }
switch ($Action) {
"Get" {
$rules = Get-DnsClientNrptRule
if ($rules) {
Write-Host "Current NRPT rules:"
$rules | Format-Table -Property Namespace, NameServers
} else {
Write-Host "No NRPT rules found"
}
}
"Add" {
# 获取当前所有的 NRPT 规则
$currentRules = Get-DnsClientNrptRule
# 添加或更新规则
foreach ($ns in $fileNamespaces) {
$rule = $currentRules | Where-Object { $_.Namespace -eq $ns }
if ($rule) {
if ($rule.NameServers -ne $NameServer) {
Set-DnsClientNrptRule -Name $
rule.Name -NameServers $NameServer
Write-Host "Updated NRPT rule for $ns $NameServer"
}
} else {
Add-DnsClientNrptRule -Namespace $ns -NameServers $NameServer
Write-Host "Added NRPT rule for $ns"
}
}
# 清除不在文件中的规则
$currentRules | Where-Object { $fileNamespaces -notcontains $_.Namespace } | ForEach-Object {
Remove-DnsClientNrptRule -Name $
_.Name Write-Host "Removed NRPT rule for $($_.Namespace)"
}
}
"Clean" {
Get-DnsClientNrptRule | Remove-DnsClientNrptRule -Force
Write-Host "Cleaned all NRPT rules"
}
default {
Write-Host "Invalid action: $Action"
}
}
}
# 调用 Manage-NrptRuleFromFile 函数
Manage-NrptRuleFromFile -Action $Action -FilePath $FilePath -NameServer $NameServer
# 示例用法
# 将内容保存为 nrpt.ps1 文件，在 CWD 内添加一份 domains.txt ，每个域名一行，比如：
#
example-01.com#
example-02.com#
example-03.com#
# 指定 NameServer 地址
# .\nrpt.ps1 -NameServer "10.0.0.2"
#
# 指定文件地址
# .\nrpt.ps1 -FilePath ".\another-domains.txt"
#
# 清除所有规则
# .\nrpt.ps1 -Action Clean
```
