如何在一行中将嵌套的JSON哈希表的全部内容输出到PSO?
$json = @"
{
"outer": "value1",
"outerArray": [
"value2",
"value3"
],
"outerHash": {
"inner": "value4",
"innerArray": [
"value5",
"value6"
],
"innerHash": {
"innermost1": "value7",
"innermost2": "value8",
"innermost3": "value9"
}
}
}
"@
当前行为:仅显示一个“级别”
$json | ConvertFrom-Json
outer outerArray outerHash
----- ---------- ---------
value1 {value2, value3} @{inner=value4; innerArray=System.Object[]; innerHash=}
所需行为:递归扩展并显示所有哈希/数组内容
$json | ConvertFrom-Json
outer outerArray outerHash
----- ---------- ---------
value1 {value2, value3} @{inner=value4; innerArray=@(value5, value6); innerHash=@{innermost1=value7; innermost2=value8; innermost3=value9}}
以下内容似乎在主题上引起轰动,但未达到预期的效果: PowerShell Hashtable from JSON PSCustomObject to Hashtable How to output multiple hash tables in Powershell

用户atscripter向包'ConvertTo-Expression'的所有者发送以下消息:
” 当我尝试修改PowerShell的默认行为时遇到了您的“ flatten-object”文章。我寻求了关于stackoverflow和technet的帮助,而不是从头开始编写代码,我想知道这有多么困难要调整“展平对象”以达到所需的效果吗?似乎该功能确实很难遍历对象,因为我只是不够熟练,无法使它们以所需的格式输出。非常感谢!“
为此,您不必重写flatten-object
cmdlet或ConvertTo-Expression
cmdlet。
您只需要遍历 first 级别,然后在每个属性上调用ConvertTo-Expression
cmdlet(或本地ConvertTo-Json
cmdlet):
以 PowerShell 格式:
$Properties = @{}
($Json | ConvertFrom-Json).PSObject.Properties |
ForEach-Object {$Properties.($_.Name) = $_.Value |
ConvertTo-Expression -Expand -1}
[PSCustomObject]$Properties
结果:
outer outerArray outerHash
----- ---------- ---------
'value1' 'value2','value3' [PSCustomObject]@{'inner'='value4';'innerArray'='value5','value6';'innerHash'=[PSCustomObject]@{'innermost1'='value7';'innermost2'='value8';'innermost3'='value9'}}
以 Json 格式:
($Json | ConvertFrom-Json).PSObject.Properties |
ForEach-Object {$Properties.($_.Name) = $_.Value |
ConvertTo-Json -Depth 5 -Compress}
结果(Json)格式略有不同
outer outerArray outerHash
----- ---------- ---------
"value1" ["value2","value3"] {"inner":"value4","innerArray":["value5","value6"],"innerHash":{"innermost1":"value7","innermost2":"value8","innermost3":"value9"}}
