Powershell 以图表类型组织输出

Question

嗨，我有以下 PS 脚本，但输出不是我想要的安排方式，请任何人帮忙解决它。 它轮询一个 txt 文件以查找包含名称和过期时间的行，我想将其显示为具有名称和过期时间列标题的 CSV，并将每个名称和过期日期存储在帽子行中：

ID         Name        Expire

ID1        Name1       01/11/2024
ID2        Name2       05/12/2025
ID3        Name3       04/12/2024

我当前的 PS 脚本：

$txtFilePath = "C:\Reports\key.txt"

$pattern1 = "id" 
$pattern2 = "names"
$pattern3 = "expires" 

$extractedData = @()

$lines = Get-Content -Path $txtFilePath
foreach ($line in $lines) {
if ($line -match $pattern1) {
$id = $line -replace '.*id*', ''
$extractedData += [pscustomobject]@{
  'Field' = '$line'
  'Value' = $id
   }
}
elseif ($line -match $pattern2) {
  $expires = $line -replace '.*name*', ''
  $extractedData += [namepscustomobject]@{
       'Field' = 'name'
       'Value' = $name
    }
}
    elseif ($line -match $pattern3) {
    $Expiry = $line -replace '.*expires*', ''
    $extractedData += [pscustomobject]@{
    'Field' = 'Expiry'
    'Value' = $Expiry
}
}
}


 $extractedData | Format-Table -AutoSize

 $extractedData | Export-Csv -Path "C:\Reports\Results\output.csv" -NoTypeInformation

Key.txt 示例：

{
"attributes": {
  "created": "2019-07-03T14:55:51+00:00",
  "enabled": true,
  "expire": "2299-12-25T07:28:38+00:00",
  "notBefore": null,
  "recoverableDays": 90,
  "recoveryLevel": "Recoverable",
  "updated": "2022-09-26T20:32:13+00:00"
 },
 "contentType": "",
"id": "https://prod-ukb2c-keyvault- 
ne.vault.azure.net/secrets/azure-log-analytics-workspace- 
customer-id",
"managed": null,
"name": "azure-log-analytics-workspace-customer-id",
"tags": {}
  },
  {

Answer 1

你的格式很糟糕，但假设输入是这样的，并且 id 字符串中间没有不正确的换行符

{
    "attributes": {
        "created": "2019-07-03T14:55:51+00:00",
        "enabled": true,
        "expire": "2299-12-25T07:28:38+00:00",
        "notBefore": null,
        "recoverableDays": 90,
        "recoveryLevel": "Recoverable",
        "updated": "2022-09-26T20:32:13+00:00"
    },
    "contentType": "",
    "id": "https://prod-ukb2c-keyvault-ne.vault.azure.net/secrets/azure-log-analytics-workspace-customer-id",
    "managed": null,
    "name": "azure-log-analytics-workspace-customer-id",
    "tags": {}
},
{
// More similar objects
}

那么该文件实际上是一种json，你可以简单地使用

ConvertFrom-Json

对其进行操作

PS C:\> $j = "[$(Get-Content C:\Reports\key.txt)]" | ConvertFrom-Json
PS C:\> $j | Select-Object -Property name, id, @{Name="attributes.expire"; Expression={($_.attributes.expire -as [datetime]).ToString("MM-dd-yyyy")}}

name  id  attributes.expire
----  --  -----------------
name1 id1 12-25-2299
name2 id2 12-25-2123
