使用Powershell读取JSON层次结构子节点数可以是任何数字文件

如何解决使用Powershell读取JSON层次结构子节点数可以是任何数字文件

使用Powershell读取JSON层次结构（子节点数可以是任何数字）文件。 我可以为一个级别执行此操作，但对于N个循环和嵌套循环也需要相同的操作 需要在树状视图中显示结果，如果不可能的话，则以表格的方式将标题放在根表的顶部

下面是到目前为止我开发的脚本：

$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}

JSON文件

解决方法

您实际上不是在读取Json文件，而是实际上是一个PowerShell对象的层次结构，该对象可能包含许多（.Net）对象类型，但是在这种情况下，它受原始Json结构的限制，该结构仅包含三种主要类型中的一种：

要通读未知深度的层次结构的最佳方法是使用recursive函数，这是一个调用自身的函数。给您一个具体问题的例子：

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，在结构可能存在任何子对象的情况下（对于[Array]或[PSCustomObject]而言，Show-Object函数使用子对象作为自身来调用自身）新的输入对象，以及一些其他参数，例如跟踪当前的$Depth。

您可以像下面这样简单地调用函数：

Show-Object $JsonContent

或将其导出到以下文件中：

Show-Object $JsonContent | Out-File .\text1.txt

对于您的$JsonContent，它将导致：
