在 powershell 中序列化 REST 响应

Question

我正在连接到 REST 服务

$response = Invoke-RestMethod -Uri $URL -Headers $headers -Method POST -Body $body_json -ContentType "application/json" 
$response.Outputs

我收到了那种格式的回复

    Actual: {
        "2017-08-29T14:37:47.137",
        "2017-08-30T13:07:09.563",
        "2017-08-30T14:41:29.023"
    },
    Start: {
        "2017-08-29T14:36:12.42",
        "2017-08-30T12:59:53.05",
        "2017-08-30T14:40:45.34"
    },
    NumScrapsList: {
        0,
        3,
        ...

但我想要那种形式

    {   
        "NumScrapsList":0,
        "Actual":"2017-08-29T14:37:47.137",
        "Start":"08-29T14:36:12.42"
    },
    {
        "NumScrapsList":3,
        "Actual":"2017-08-30T13:07:09.563",
        "Start":"2017-08-30T12:59:53.05"
    }

在 pythonic 方法中，我可以这样做（包括“输出”键）：

outputs = [dict(zip(resp['Outputs'].keys(), e))
           for e in zip(*resp['Outputs'].values())]

pprint(outputs)

但在 powershell 中我不知道该怎么做。你能告诉我正确的方向吗？

使用 Invoke-RestMethod

中的完整 $response.outputs 编辑
$response.outputs 是

Type : {a, b, c} Code : {xxx, yyy, eee} CompletionDate : {1900-01-01T00:00:00, 1900-01-01T00:00:00, 1900-01-01T00:00:00} OrderQuantity : {30, 30, 3} NumScraps : {0, 0, 0} ActualDate : {2021-11-16T15:17:00, 2021-11-16T15:18:00, 1900-01-01T00:00:00} Status : {WT, FD, RT} Order : {70000, 30794, 94098} Sequence : {0300, 0400, 0500}

然后我可以转换为-json，输出是：

{ "Type": [ "a", "b", "c" ], "Code": [ "xxx", "yyy", "eee" ], "CompletionDate": [ "1900-01-01T00:00:00", "1900-01-01T00:00:00", "1900-01-01T00:00:00" ], "OrderQuantity": [ 30, 30, 3 ], "NumScraps": [ 0, 0, 0 ], "ActualDate": [ "2021-11-16T15:17:00", "2021-11-16T15:18:00", "1900-01-01T00:00:00" ], "Status": [ "WT", "FD", "RT" ], "Order": [ "70000", "30794", "94098" ], "Sequence": [ "0300", "0400", "0500" ] }

那是说 waitingforguacamole 解决方案即使有点棘手也能奏效（当然，谢谢你的帮助！）

Answer 1

好吧，我试了一下，也许不够优雅（它既不是功能性的也不是 Pythonic 的），我相信其他人会有 far 更具表现力的方法，但这可能是一个开始：

我清理了 JSON 看起来像这样

{
    "Actual": [
        "2017-08-29T14:37:47.137",
        "2017-08-30T13:07:09.563",
        "2017-08-30T14:41:29.023"
    ],
    "Start": [
        "2017-08-29T14:36:12.42",
        "2017-08-30T12:59:53.05",
        "2017-08-30T14:40:45.34"
    ],
    "NumScrapsList": [
        0,
        3,
        7
    ]
}

（为了完整性，我在NumScrapsList中加了一个值，并将每个顶级JSON字段变成了一个数组）

然后，

#simulate your REST method call result
$json = "{
    `"Actual`": [
        `"2017-08-29T14:37:47.137`",
        `"2017-08-30T13:07:09.563`",
        `"2017-08-30T14:41:29.023`"
    ],
    `"Start`": [
        `"2017-08-29T14:36:12.42`",
        `"2017-08-30T12:59:53.05`",
        `"2017-08-30T14:40:45.34`"
    ],
    `"NumScrapsList`": [
        0,
        3,
        7
    ]
}"

#create a field map
$fieldMap = @("NumScrapsList", "Start", "Actual")

#convert the JSON to a Powershell object, create an empty array
$in = $json | ConvertFrom-JSON

#using NumScrapsList as your iterator
0..($in.NumScrapsList.Count-1) | ForEach-Object {
    $fieldMap | ForEach-Object -Begin {
        #reference the outer loop index
        $index = $_
        #initialize an accumulator for the object whose properties to be mapped
        $obj = @{}
    } -Process {
        #in order of fieldMap's properties, grab those fields from the input
        #and add them to the accumulator by name
        $obj."$_" = $in."$_"[$index]
    } -End {
        #return that accumulator
        $obj
    }
} | ConvertTo-Json

并且该处理块可以减少为：

$fieldMap = @("NumScrapsList", "Start", "Actual"); 
$in = $json | ConvertFrom-JSON
0..($in.NumScrapsList.Count-1) | ForEach-Object { 
    $fieldMap | ForEach-Object { $index = $_; $obj = @{} } {
        $obj."$_" = $in."$_"[$index]
    } { $obj }
} | ConvertTo-Json
