Powershell: Compare-object not Compare嵌套对象

Question

也不知道我是如何停止担心，学会了喜欢上了收集的弦

给定以下两个json字符串：

$jsonString1 = '{ "baz": "quuz", "cow": [ "moo", "CUD" ], "foo": "bar" }'
$jsonstring2 = '{ "baz": "quuz", "cow": [ "moo", "GRASS" ], "foo": "bar" }'

我想要了解它们所表示的对象之间的差异

<# First attempt: Convert each to an object, then compare normally #>
function Compare-Json {
    <# Make powershell objects from each string #>
    $obj1 = $jsonString1 | ConvertFrom-Json
    $obj2 = $jsonstring2 | ConvertFrom-Json

    Compare-Object $obj1 $obj2
}

PS E:\temp> Compare-Json

PS E:\temp> 

是的，这根本就不是输出。

当前的解决方法是将json转换为对象，再转换回字符串，然后拆分字符串，最后比较每个集合。

function Compare-Json {
    <# Convert to pretty json, then split to make a string array #>
    $obj1 = $($jsonString1 | ConvertFrom-Json | ConvertTo-Json) -split ([Environment]::NewLine)
    $obj2 = $($jsonstring2 | ConvertFrom-Json | ConvertTo-Json) -split ([Environment]::NewLine)

    Compare-Object $obj1 $obj2
}


PS E:\temp> Compare-Json

InputObject      SideIndicator                                               
-----------      -------------                                               
"GRASS"          =>                                                          
"CUD"            <=                                                          

PS E:\temp> 

有没有更简单的方法来深入比较两个对象？

不知道这是不是更好，但是：

$jsonString1 = '{ "baz": "quuz", "cow": [ "moo", "CUD" ], "foo": "bar" }'
$jsonstring2 = '{ "baz": "quuz", "cow": [ "moo", "GRASS" ], "foo": "bar" }'

compare $jsonString1.split(',:[]{}') $jsonString2.split(',:[]{}')


InputObject                                          SideIndicator                                      
-----------                                          -------------                                      
 "GRASS"                                             =>                                                 
 "CUD"                                               <=
