# 创建 JSON 信息获取函数
function Get-JSONInfo {
    param(
        [string]$JSONPath
    )
    
    try {
        $json = Get-Content $JSONPath -Raw | ConvertFrom-Json
        
        return [PSCustomObject]@{
            FileName = Split-Path $JSONPath -Leaf
            FileSize = (Get-Item $JSONPath).Length
            PropertyCount = ($json.PSObject.Properties | Measure-Object).Count
            IsArray = $json -is [Array]
            Depth = Get-JSONDepth $json
        }
    }
    catch {
        Write-Host "获取 JSON 信息失败：$_"
    }
}

# 获取 JSON 深度
function Get-JSONDepth {
    param($Object)
    
    if ($Object -is [Array]) {
        return 1 + ($Object | ForEach-Object { Get-JSONDepth $_ } | Measure-Object -Maximum).Maximum
    }
    elseif ($Object -is [PSCustomObject]) {
        return 1 + ($Object.PSObject.Properties | ForEach-Object { Get-JSONDepth $_.Value } | Measure-Object -Maximum).Maximum
    }

            if ($Object -is [Array]) {
                for ($i = 0; $i -lt $Object.Count; $i++) {
                    Search-Object $Object[$i] "$Path[$i]"
                }
            }
            elseif ($Object -is [PSCustomObject]) {
                foreach ($property in $Object.PSObject.Properties) {
                    $newPath = if ($Path) { "$Path.$($property.Name)" } else { $property.Name }
                    Search-Object $property.Value $newPath
                }
            }
            else {
                $value = $Object.ToString()
                $matched = switch ($MatchType) {
                    "exact" { $value -eq $Query }
                    "contains" { $value -like "*$Query*" }
                    "regex" { $value -match $Query }
                }
                
                if ($matched) {
                    $results += [PSCustomObject]@{
                        Path = $Path
                        Value = $value
                    }
                }
            }
        }
        
        Search-Object $json
        return $results
    }
    catch {
        Write-Host "查询失败：$_"
    }
}

这些技巧将帮助您更有效地处理 JSON 数据。记住，在处理 JSON 时，始终要注意数据的完整性和格式的正确性。同时，建议在处理大型 JSON 文件时使用流式处理方式，以提高性能。

PowerShell 技能连载 - 对象属性操作

属性操作基础

1

# 动态添加属性
$process = Get-Process -Id $PID
$process | Add-Member -MemberType NoteProperty -Name 'HostName' -Value $env:COMPUTERNAME

# 属性选择器
Get-Service | Select-Object -Property Name,Status,@{Name='Uptime';Expression={(Get-Date) - $_.StartTime}}

应用场景

  1. 动态数据增强：

    1
    2
    3
    Get-ChildItem | ForEach-Object {
        $_ | Add-Member -MemberType ScriptProperty -Name SizeMB -Value { [math]::Round($this.Length/1MB,2) }
    }

  2. 自定义输出视图：

    1
    2
    3
    4
    $diskInfo = Get-CimInstance Win32_LogicalDisk
    $diskInfo | Select-Object DeviceID,VolumeName,
        @{Name='Total(GB)';Expression={$_.Size/1GB -as [int]}},
        @{Name='Free(%)';Expression={($_.FreeSpace/$_.Size).ToString("P")}}

最佳实践

  1. 使用PSObject包装原生对象

    1
    2
    3
    4
    5
    6
    $rawObject = Get-WmiObject Win32_Processor
    $customObj = [PSCustomObject]@{
        Name = $rawObject.Name
        Cores = $rawObject.NumberOfCores
        Speed = "$($rawObject.MaxClockSpeed)MHz"
    }

  2. 扩展方法实现属性验证

    1
    2
    3
    4
    5
    6
    7
    class SecureProcess {
        [ValidatePattern("^\w+$")]
        [string]$ProcessName

        [ValidateRange(1,100)]
        [int]$Priority
    }

  3. 利用属性集提升效率

    1
    2
    Update-TypeData -TypeName System.IO.FileInfo -MemberType ScriptProperty 
        -MemberName Owner -Value { (Get-Acl $this.FullName).Owner }

最佳实践

  1. 实施配置收集
  2. 验证配置合规性
  3. 管理配置部署
  4. 保持详细的配置记录
  5. 定期进行配置验证
  6. 实施部署策略
  7. 建立配置基线
  8. 保持系统文档更新

  2. 建立完整的分析体系
  3. 制定优化策略
  4. 保持详细的运行记录
  5. 定期进行系统评估
  6. 实施访问控制策略
  7. 建立应急响应机制
  8. 保持系统文档更新

最佳实践

  1. 实施场景自动扩展
  2. 建立资源调度策略
  3. 实现性能监控
  4. 保持详细的运行记录
  5. 定期进行系统评估
  6. 实施访问控制策略
  7. 建立应急响应机制

PowerShell 技能连载 - GitOps自动化部署

function Sync-GitOpsDeployment {
    [CmdletBinding()]
    param(
        [Parameter(Mandatory=$true)]
        [string]$RepoUrl,
        
        [ValidateSet('dev','prod')]
        [string]$Environment = 'dev'
    )

    $workdir = Join-Path $env:TEMP "gitops-$(Get-Date -Format 'yyyyMMddHHmmss')"
    
    try {
        # 克隆配置仓库
        git clone $RepoUrl $workdir
        
        # 应用环境配置
        $manifests = Get-ChildItem -Path $workdir/$Environment -Filter *.yaml
        $manifests | ForEach-Object {
            kubectl apply -f $_.FullName
        }
        
        # 生成同步报告
        [PSCustomObject]@{
            Timestamp = Get-Date
            SyncedFiles = $manifests.Count
            Environment = $Environment
            CommitHash = (git -C $workdir rev-parse HEAD)
        }
    }
    catch {
        Write-Error "GitOps同步失败: $_"
    }
    finally {
        Remove-Item $workdir -Recurse -Force -ErrorAction SilentlyContinue
    }
}

实现原理：

  1. 临时克隆Git仓库获取最新配置
  2. 按环境目录筛选Kubernetes清单文件
  3. 使用kubectl批量应用资源配置
  4. 生成包含提交哈希的同步报告
  5. 自动清理临时工作目录

使用示例：

1
Sync-GitOpsDeployment -RepoUrl 'https://github.com/user/config-repo' -Environment 'prod'

最佳实践：

  1. 与Webhook集成实现变更触发
  2. 添加配置差异比对功能
  3. 实现同步历史版本追溯
  4. 集成通知机制报告异常

注意事项：
• 需要配置git和kubectl命令行工具
• 生产环境建议使用SSH密钥认证
• 重要变更应通过PR流程审核

PowerShell 技能连载 - 跨平台脚本编写技巧

随着PowerShell Core的发展，PowerShell已经成为真正的跨平台自动化工具。本文将介绍如何编写在Windows、Linux和macOS上都能正常运行的PowerShell脚本。

检测操作系统平台

首先，让我们学习如何检测脚本运行的操作系统平台：

        return "Windows"
    }
    elseif ($IsLinux) {
        return "Linux"
    }
    elseif ($IsMacOS) {
        return "macOS"
    }
    else {
        return "Unknown"
    }
}

$platform = Get-CurrentPlatform
Write-Host "当前运行平台: $platform"

处理文件路径

在不同操作系统上，文件路径的格式和分隔符有所不同。使用PowerShell提供的内置方法可以解决这个问题：

function Get-CrossPlatformPath {
    param(
        [string]$Path
    )
    
    # 使用Join-Path确保路径分隔符正确
    $normalizedPath = $Path
    
    # 处理根路径
    if ($IsWindows -or ($PSVersionTable.PSVersion.Major -lt 6 -and $env:OS -eq "Windows_NT")) {
        # 在Windows上，确保使用正确的驱动器表示法
        if (-not $normalizedPath.Contains(':') -and $normalizedPath.StartsWith('/')) {
            $normalizedPath = "C:$normalizedPath"
        }
    }
    else {
        # 在Linux/macOS上，将Windows路径转换为Unix风格
        if ($normalizedPath -match '^[A-Za-z]:') {
            $normalizedPath = $normalizedPath -replace '^[A-Za-z]:', ''
            $normalizedPath = $normalizedPath -replace '\\', '/'
            $normalizedPath = "/$normalizedPath"
        }
    }
    
    # 确保所有分隔符都是平台适用的
    $normalizedPath = $normalizedPath -replace '[/\\]', [System.IO.Path]::DirectorySeparatorChar
    
    return $normalizedPath
}

# 示例
$path = "/temp/test.txt"
$platformPath = Get-CrossPlatformPath -Path $path
Write-Host "跨平台路径: $platformPath"

执行平台特定命令

    $platform = Get-CurrentPlatform

        }
        default {
            Write-Error "不支持的平台: $platform"
        }
    }
}

# 示例：获取系统信息

                      -LinuxCommand "uname -a" `

# 执行主函数
Main

最佳实践总结

  1. 始终检测平台：使用$IsWindows、$IsLinux和$IsMacOS变量确定当前平台。
  2. 使用内置路径处理：利用Join-Path、Split-Path和[System.IO.Path]类处理跨平台路径。
  3. 避免硬编码路径分隔符：使用[System.IO.Path]::DirectorySeparatorChar代替硬编码的\或/。
  4. 利用条件逻辑：为不同平台编写特定的代码分支。
  5. 使用.NET Core的跨平台API：尽可能使用.NET Core提供的跨平台API而不是平台特定命令。
  6. 测试、测试再测试：在所有目标平台上测试您的脚本。

通过遵循这些技巧和最佳实践，您可以编写出在所有主要操作系统上都能无缝运行的PowerShell脚本，充分发挥PowerShell跨平台能力的优势。

最佳实践

  1. 管理设备配置
  2. 同步教育内容
  3. 监控设备状态
  4. 保持详细的运行记录
  5. 定期进行性能评估
  6. 实施同步策略
  7. 建立预警机制
  8. 保持系统文档更新

最佳实践

  1. 实施配置收集
  2. 验证配置合规性
  3. 管理配置部署
  4. 保持详细的配置记录
  5. 定期进行配置审查
  6. 实施回滚策略
  7. 建立配置控制
  8. 保持系统文档更新
