json - 无法为嵌套属性添加值

Question

我正在努力修改深度嵌套在 PSObject 中的属性数据。如果我尝试修改这些值，Powershell 只会抛出异常，指出它找不到该值，但如果我只是调用该值本身，就可以毫无问题地找到它。

json对象的原始数据如下所示:

[

                },
                {
                    "@FIELD_ID": 1022,

                    "VALUES": {
                        "VALUE": [
                            {
                                "value": "Auth 1"
                            },
                            {
                                "value": "Auth 2"
                            },
                            {
                                "value": "Auth 3"
                            },
                            {
                                "value": "Auth 4"
                            }
                        ]
                    }
                }
            ]
        }
    }
]

我当前的代码:

$users = get-content "C:\Working-Branch\Temp\NotFoundUsers - Copy.txt"| ConvertFrom-Json



foreach($user in $users){
  $user.CUSTOM_FIELDS.FIELD.values.Value.value
  $NewValue = $user.CUSTOM_FIELDS.FIELD.values.Value.value
  $NewValue += "Test"
  $NewValue
  $($user.CUSTOM_FIELDS.FIELD.values.Value).value = $newValue
}

这会产生以下输出:

Auth 1
Auth 2
Auth 3
Auth 4
Auth 1
Auth 2
Auth 3
Auth 4
Test
The property 'value' cannot be found on this object. Verify that the property exists and can be set.
At line:10 char:5
+   $($user.CUSTOM_FIELDS.FIELD.values.Value).value = $newValue
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : PropertyAssignmentException

所以我知道该属性存在，因为我调用它两次，一次直接在对象上调用，一次在我向其添加值“test”之后调用。但是当我尝试更新 Orignal 对象时，它说无法在对象上找到值“Value”。

我尝试按照This post中的建议进行操作，但对我来说仍然失败。我同时使用“+=”运算符和“=”运算符。两者都出现同样的错误。

我认为您需要找到包含成员Values的字段

$newvalue =@{
    "value" = "Test"
    }

foreach($user in $users){

  $array = $user.CUSTOM_FIELDS.FIELD.values.value
  $array += $newvalue

  foreach ($field in $user.CUSTOM_FIELDS.FIELD)
  {
    if ($field.values -ne $null)
    {
        $field.values.value = $array
    }
  }

  $user.CUSTOM_FIELDS.FIELD.values.Value
}

然后 $user.CUSTOM_FIELDS.FIELD.values.Value 的输出为

value

Auth 1
Auth 2
Auth 3
Auth 4
