使用 Powershell 读取 JSON 层次结构（子节点数可以是任意数字）文件
Reading the JSON hierarchy (Number of subnodes can be any number) file using Powershell
正在使用 Powershell 读取 JSON 层次结构（子节点数可以是任意数字）文件。
我可以在一个级别上执行此操作，但 N 个循环和嵌套循环需要相同的级别
需要树视图中的结果，如果不可能，则采用表格方式，标题位于根 table
之上
下面是我目前开发的脚本：
$Filepath = 'C:\Users\Learner\Test2.JSON'
$JsonContent=gc $Filepath | ConvertFrom-Json
$RootNodeCount=$JsonContent.psobject.Properties.name.Count
$RootNodeName=$JsonContent.psobject.Properties.name
foreach ($Name in $RootNodeName) {Echo $Name--> $JsonContent.$Name}

您并不是真正在阅读 Json 文件，而是实际上是 PowerShell object 的层次结构，它可能包含很多 (.Net) object 类型，但在这种情况下它受限于原来的 Json 结构，它只包含三种主要类型：
- 数组，包含多个child objects
- PSCustomObjects (unless you use the
ConvertFrom-Json -AsHashTable 参数），包含分配给特定名称的 child object。
- Primitives（包括字符串），它基本上是一个没有 children.[=45 的 object ("leaf") =]
阅读未知深度的层次结构的最佳方法是使用 recursive 函数，即调用自身的函数。为您的具体问题举个例子：
Function Show-Object ($Object, $Depth = 0, $Name) {
$Indent = if ($Depth++) { " " * ($Depth - 2) }
if ($Object -is [Array]) {
If ($Name) { "$Indent$Name =" }
foreach ($Item in $Object) {
Show-Object $Item $Depth
}
}
elseif ($Object -is [PSCustomObject]) {
If ($Name) { "$Indent$Name =" }
foreach ($Name in $Object.PSObject.Properties.Name) {
Show-Object $Object.$Name $Depth $Name
}
}
else {
if ($Name) { "$Indent$Name = $Object" } else { "$Indent$Object" }
}
}
如您所见，结构可能是 child object（在 [Array] 或 [PSCustomObject] 的情况下），Show-Object 函数使用 child object 作为新输入 object 和一些附加参数调用自身，例如跟踪当前 $Depth.
您可以像这样简单地调用该函数：
Show-Object $JsonContent
或将其导出到如下文件：
Show-Object $JsonContent | Out-File .\text1.txt
对于您的 $JsonContent 它将导致：
