Powershell ConvertTo-json输出为小写

我使用下面的命令生成以下输出

$VMHost | ConvertTo-json | Out-File -encoding "UTF8" -FilePath  ".\$VMHostName.report"

但我需要所有小写和值的键,如下所示

 "HostNumaStatus": [
      {
         "ComputerName": "TEMSA10",
         "MemoryAvailable": 3119,
         "MemoryTotal": 6075,
         "NodeId": 0,
         "ProcessorsAvailability": "35 41 56 58"
      }
   ]

 "hostnumastatus": [
      {
         "computername": "TEMSA10",
         "memroyavailable": 3119,
         "memroytotal": 6075,
         "nodeid": 0,
         "processoravailability": "35 41 56 58"
      }
   ]

我会使用[Regex]静态方法Replace

$Json = $VMHost | ConvertTo-Json

[regex]::Replace(
    $Json,
    '(?<=")(\w+)(?=":)',
    {
        $args[0].Groups[1].Value.ToLower()

    }
)

将它放在$ VMHost和ConvertTo-JSON之间。

Select -Property @{N='computername';E={$_.ComputerName}}, @{N='memoryavailable';E={$_.MemoryAvailable}}, @{N='memorytotal';E={$_.MemoryTotal}}, @{N='nodeid';E={$_.NodeId}}, @{N='processorsavailability';E={$_.ProcessorsAvailability}}

由于列不是静态的,请尝试:

$cols = $VMHost | select * | Get-Member | ForEach-Object {@{N=$_.Name.ToLower();E=$_.Name}}
$VMHost | Select -Property $cols | ConvertTo-Json | Out-File -encoding "UTF8" -FilePath  ".\$VMHostName.report"

我真的想在转换之前修改对象,但这样可以获得您之后的最终结果:

# Get the JSON text
$JSON = $VMHost | ConvertTo-Json

# Loop through each line of the JSON output
$JSON.Split("`n") | ForEach-Object {
    # Split the line on the ":", grab the first portion, and trim the space
    $value = $_.Split(":")[0].Trim()
    # Check to see if both the start and end characters are quotes (these should be the key fields)
    if (($value.Substring(0,1) -eq "`"") -and ($value.Substring($value.Length-1,1) -eq "`"")) {
        # If it's a key make it lowercase
        $_.Replace($value,$value.ToLower())
        } else {
        # Otherwise leave it as-is
        $_
        }
    # Output
    } | Out-File -encoding "UTF8" -FilePath  ".\$VMHostName.report"

这不是最好的解决方案,而是等待更好的

的拐杖
# Get the JSON text
$JSON = $VMHost | ConvertTo-Json
$JSON.Split("`n") | % {if($_ -match "(.*):(.*)"){$_ -replace '(.*):(.*)',"$($matches[1].ToLower()):$($matches[2])"}else{$_}}

我使用正则表达式将所有键转换为小写,必须使用各种JSON进行测试

也许有人可以提供更好的语法。

这对我来说效果很好。希望有帮助。

$data | ConvertTo-Json |Out-File "jsonfile.json"
(Get-Content -Path ".\jsonfile.json" -Raw).ToLower() |Out-File "jsonfile.json" -force -Encoding "UTF8"
