Question

我需要从Powershell的json中读取一些信息。我遇到的问题是＆＃34;路径＆＃34;第一节我不能指定下一个名字，例如调用路径是因为它发生了变化。然后我需要得到＆＃34;得到＆＃34;部分，然后是＆＃34;参数＆＃34;部分，最后得到名称和必填字段。

我可以使用$info.host和$info.paths之类的路径获取主机名。然后我通过遍历路径得到各个路径名称，以获得这样的每个名称。

foreach($item in $pName)
{
    $item  
}

但那就是我可以得到我尝试使用$ item.childItem，但它不起作用。无论如何使用$ item.paths.childItems [$ 1] .get.parameters之类的东西，然后获取名称和必填字段值？

json看起来像这样：

{
"swagger": "2.0",
"info": {
"version": "v1",
"title": "Requirements.API"
},
"host": "replica.net",
"schemes": [
"http"
],
"paths": {
"/": {
"get": {
"tags": [
"Alive"
],
"operationId": "Alive_Get",
"consumes": [],
"produces": [
"application/json",
"text/json",
"application/xml",
"text/xml"
],
"responses": {
"200": {
"description": "OK",
"schema": {
"$ref": "#/definitions/Object"
}
}
},
"deprecated": false
}
},
"/requirements/email-docs": {
"get": {
"tags": [
"CustomerRequirement"
],
"operationId": "",
"consumes": [],
"produces": [
"application/json",
"text/json",
"application/xml",
"text/xml"
],
"parameters": [
{
"name": "name",
"in": "query",
"required": true,
"type": "integer",
"format": "int32"
}
],
"responses": {
"200": {
"description": "OK",
"schema": {
"type": "array",
"items": {
"$ref": "#/definitions/UploadResponse"
}
}
}
},
"deprecated": false
}
},

Answer 1

我用它来得到它：

  for($i=0;$i-lt$pName.Count;$i++)
            {
                $test | Select -ExpandProperty paths | select -ExpandProperty $pName[$i] | select -ExpandProperty get

            }

您的JSON文件格式不清晰，并且遗漏了一些右括号。然而，在关闭JSON文件并将其读入PowerShell（ConvertFrom-Json）后，您的PowerShell对象如下所示（使用PSON或Write-Log）：

{
        swagger: "2.0",
        info: {
                version: "v1",
                title: "Requirements.API"
        },
        host: "replica.net",
        schemes: @(
                "http"
        ),
        paths: {
                /: {
                        get: {
                                tags: @(
                                        "Alive"
                                ),
                                operationId: "Alive_Get",
                                consumes: @(),

                                ),

                                                }
                                        }
                                },

                                ),
                                operationId: "",
                                consumes: @(),
                                produces: @(

                                parameters: @(
                                        {
                                                name: "name",
                                                in: "query",
                                                required: $True,
                                                type: "integer",
                                                format: "int32"
                                        }
                                ),
                                responses: {
                                        200: {
                                                description: "OK",
                                                schema: {
                                                        type: "array",
                                                        items: {
                                                                $ref: "#/definitions/UploadResponse"
                                                        }
                                                }
                                        }
                                },
                                deprecated: $False
                        }
                }
        }
}

所以我猜你要找的属性/值是：

$Item.paths.PSObject.Properties | Select -ExpandProperty Name

如何在powershell中迭代json，而无法指定值。
