# 基础try/catch结构
try {

}
catch {

}
finally {
    Write-Host "清理操作"
}

错误类型对比

错误类型 触发条件 处理方式
终止错误 严重运行时错误 try/catch
非终止错误 可继续执行错误 -ErrorAction
语法错误 脚本解析错误 预检查

典型应用场景

  1. 使用$Error自动变量追溯错误历史
  2. 通过-ErrorVariable捕获特定命令错误
  3. 设置$ErrorActionPreference控制全局行为
  4. 自定义错误信息模板

PowerShell 技能连载 - Kubernetes 集群管理

在云原生架构中，Kubernetes已成为容器编排的事实标准。本文演示如何通过PowerShell实现多集群管理、资源部署和性能监控。

function Invoke-K8sDeployment {
    param(
        [ValidateSet('AzureAKS','AWS-EKS')]
        [string]$ClusterType,
        [string]$Namespace,
        [string]$DeploymentFile
    )

    try {
        # 认证集群
        $kubeconfig = switch ($ClusterType) {
            'AzureAKS' { Get-AzAksCredential -Admin }
            'AWS-EKS' { Get-EksClusterCredential }
        }

        # 执行部署
        kubectl apply -f $DeploymentFile --namespace $Namespace --kubeconfig $kubeconfig

        # 实时监控
        $watchJob = Start-Job -ScriptBlock {
            kubectl get pods --namespace $using:Namespace --watch
        }
        Receive-Job $watchJob -Wait
    }
    catch {
        Write-Error "部署失败：$_"
    }
    finally {
        Remove-Job $watchJob -Force
    }
}

实现原理分析：

  1. 集成云服务商CLI实现多集群认证
  2. 原生kubectl命令封装保证兼容性
  3. 后台作业实时监控部署状态
  4. 异常处理覆盖网络中断和配置错误

该方案将复杂的K8s运维操作简化为标准化命令，特别适合需要同时管理多个集群的DevOps团队。

}

典型应用场景

  1. 生产环境实时诊断
  2. 集群脚本批量调试
  3. 受限会话权限分析
  4. 跨域脚本问题追踪

安全注意事项

  • 使用受限端点配置
  • 加密调试信道通信
  • 清理临时调试会话
  • 审计调试日志留存

PowerShell 技能连载 - 参数验证机制

参数验证基础

PowerShell 提供多种参数验证属性来确保输入合规性：

function Get-UserInfo {
    [CmdletBinding()]
    param(
        [Parameter(Mandatory=$true)]
        [ValidatePattern("^[a-zA-Z]\\w{3,20}$")]
        [string]$UserName,

        [ValidateSet('Active','Disabled','Archived')]
        [string]$Status = 'Active',

        [ValidateRange(18,120)]
        [int]$Age
    )
    # 函数逻辑...
}

验证类型详解

  1. Mandatory验证：

    1
    2
    [Parameter(Mandatory=$true, HelpMessage="请输入用户ID")]
    [string]$UserID

  2. 正则表达式验证：

    1
    2
    [ValidatePattern("^\\d{4}-\\d{2}-\\d{2}$")]
    [string]$BirthDate

  3. 脚本块验证：

    1
    2
    3
    4
    5
    6
    7
    [ValidateScript({
        if ($_ -notmatch "^CN=") { 
            throw "必须使用LDAP格式"
        }
        $true
    })]
    [string]$DistinguishedName

最佳实践

  1. 组合使用多个验证属性
  2. 为复杂验证添加帮助信息
  3. 在验证失败时提供友好提示
  4. 优先使用内置验证属性

最佳实践

  1. 实施知识收集
  2. 组织知识结构
  3. 共享知识内容
  4. 保持详细的知识记录
  5. 定期进行知识审查
  6. 实施共享策略
  7. 建立访问控制
  8. 保持系统文档更新

  2. 采集设备数据
  3. 管理设备固件
  4. 保持详细的运行记录
  5. 定期进行设备检查
  6. 实施数据备份策略
  7. 建立预警机制
  8. 保持系统文档更新

# 获取交易数据
$tradingData = Get-TradingData -Symbol "AAPL" `
    -StartTime (Get-Date).AddHours(-4) `
    -EndTime Get-Date `
    -Interval "5m"

# 分析交易风险
$riskAnalysis = Analyze-TradingRisk -TradingData $tradingData `
    -RiskThreshold 0.02 `
    -PositionSize 1000 `
    -StopLoss 150 `
    -TakeProfit 200

# 检测交易异常
$anomalies = Detect-TradingAnomalies -TradingData $tradingData `
    -PriceThreshold 0.05 `
    -VolumeThreshold 2.0 `
    -TimeWindowMinutes 5

最佳实践

  1. 实现实时数据采集和缓存机制
  2. 使用多级风险预警系统
  3. 建立完整的异常处理流程
  4. 实施交易限额管理
  5. 定期进行回测和性能评估
  6. 保持详细的审计日志
  7. 实现自动化的风险报告生成
  8. 建立应急响应机制

            $results += $data
        }
    }
    end {
        $results
    }
}

管道输入优化

# 支持三种输入方式
'Server01','Server02' | Get-SystemInfo -Category Memory

Get-Content servers.txt | Get-SystemInfo

Get-SystemInfo -ComputerName (Import-Csv -Path datacenter.csv).Name

最佳实践：

  • 使用begin/process/end块处理流水线
  • 通过ValidatePattern限制输入格式
  • 利用ValueFromPipeline属性支持管道
  • 添加帮助注释增强可维护性
