            IsArray = $json -is [Array]
            Depth = Get-JSONDepth $json
        }
    }
    catch {
        Write-Host "获取 JSON 信息失败：$_"

    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

# 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

PowerShell 技能连载 - 配置管理

在系统管理中，配置管理对于确保系统的一致性和可维护性至关重要。本文将介绍如何使用PowerShell构建一个配置管理系统，包括配置收集、验证和部署等功能。

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

PowerShell 技能连载 - 能源管理系统

在能源管理领域，系统化管理对于提高能源利用效率和降低运营成本至关重要。本文将介绍如何使用PowerShell构建一个能源管理系统，包括能源监控、消耗分析、优化控制等功能。

能源监控

首先，让我们创建一个用于监控能源使用的函数：

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

        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：

        [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

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

# 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
