如何使用PowerShell获取IIS的Application Setting属性并筛选符合要求的站点

前提要求 #

• 以管理员身份运行PowerShell
• 提前安装并导入IISAdministration模块，可执行Install-Module IISAdministration完成安装

功能说明 #

实现读取IIS全部站点的应用程序设置，筛选出MonitoringEnabled = True的站点，逐个发起Web请求校验响应是否包含OK标识，最终将所有站点的健康状态导出为JSON文件保存到C盘health.json路径。

完整可用代码 #

# 导入IIS管理模块
Import-Module IISAdministration

# 初始化健康结果数组
$siteHealthResult = @()

# 获取所有IIS站点
$allSites = Get-IISSite

foreach ($site in $allSites) {
    # 读取站点的Application Settings配置
    $webConfigPath = Join-Path $site.Applications["/"].VirtualDirectories["/"].PhysicalPath "web.config"
    if (-not (Test-Path $webConfigPath)) {
        # 站点无web.config直接跳过
        continue
    }
    $webConfig = [xml](Get-Content $webConfigPath)
    $monitoringEnabled = $webConfig.configuration.appSettings.add | Where-Object {$_.key -eq "MonitoringEnabled"} | Select-Object -ExpandProperty value -ErrorAction SilentlyContinue

    # 筛选监控开启的站点
    if ($monitoringEnabled -ne "True") {
        continue
    }

    # 取站点第一个HTTP/HTTPS绑定的地址构造请求URL
    $binding = $site.Bindings | Where-Object {$_.Protocol -in "http","https"} | Select-Object -First 1
    if (-not $binding) {
        $siteHealthResult += @{
            SiteName = $site.Name
            Healthy = "False"
            Remark = "无可用HTTP/HTTPS绑定"
        }
        continue
    }
    $bindingInfo = $binding.BindingInformation.Split(':')
    $requestUrl = "$($binding.Protocol)://$($bindingInfo[2])$(if($bindingInfo[1] -ne '80' -and $bindingInfo[1] -ne '443'){":$($bindingInfo[1])"})"

    # 发起Web请求校验响应
    try {
        $response = Invoke-WebRequest -Uri $requestUrl -UseBasicParsing -TimeoutSec 10
        $healthStatus = if ($response.Content -match "OK") {"True"} else {"False"}
    }
    catch {
        $healthStatus = "False"
    }

    # 写入结果
    $siteHealthResult += @{
        SiteName = $site.Name
        RequestUrl = $requestUrl
        Healthy = $healthStatus
    }
}

# 导出为JSON文件
$siteHealthResult | ConvertTo-Json -Depth 3 | Out-File -FilePath "C:\health.json" -Encoding utf8

注意事项 #

• 若站点绑定的是域名，需要确保运行脚本的机器能正常解析该域名
• 可根据实际需求调整请求超时时间、响应匹配规则
• 导出的JSON默认使用UTF8编码，避免中文乱码
