Question

尽管我的对象是合法的Json，但是ConvertFrom-Json无法成功地将我的Json解析为对象。

我正在使用最新版本的Powershell。

当我尝试解析像这样的谷歌请求JSON主体时：

{
    "reportScope":  {
                        "agencyId":  "11111111111111111",
                        "advertiserId":  "22222222222222222"
                    },
    "reportType":  "adGroup",
    "columns":  [
                    {
                        "columnName":  "status"
                    },
                    {
                        "columnName":  "date"
                    },
                    {
                        "columnName":  "account"
                    },
                    {
                        "columnName":  "accountType"
                    },
                    {
                        "columnName":  "campaign"
                    },
                    {
                        "columnName":  "adGroup"
                    },
                    {
                        "columnName":  "deviceSegment"
                    },
                    {
                        "columnName":  "impr"
                    },
                    {
                        "columnName":  "clicks"
                    },
                    {
                        "columnName":  "dfaRevenue"
                    },
                    {
                        "columnName":  "cost"
                    },
                    {
                        "columnName":  "avgPos"
                    }
                ],
    "timeRange":  {
                      "startDate":  "2017-09-13",
                      "endDate":  "2017-08-14"
                  },
    "filters":  [
                    {
                        "column":  {"columnName":  "impr"},
                        "operator":  "greaterThan",
                        "values":  "0"
                    }
                ],
    "downloadFormat":  "csv",
    "maxRowsPerFile":  6000000,
    "statisticsCurrency":  "agency",
    "verifySingleTimeZone":  "false",
    "includeRemovedEntities":  "false"
}

我得到一个这样的对象：

[DBG]: PS Microsoft.PowerShell.Core\FileSystem::\\psDashboard>> $objJson


reportScope            : @{agencyId=11111111111111111; advertiserId=22222222222222222}
reportType             : adGroup
columns                : {@{columnName=status}, @{columnName=date}, @{columnName=account}, @{columnName=accountType}...}
timeRange              : @{startDate=2017-09-13; endDate=2017-08-14}
filters                : {@{column=; operator=greaterThan; values=0}}
downloadFormat         : csv
maxRowsPerFile         : 6000000
statisticsCurrency     : agency
verifySingleTimeZone   : false
includeRemovedEntities : false




[DBG]: PS Microsoft.PowerShell.Core\FileSystem::\\psDashboard>> $objJson.filters

column operator    values
------ --------    ------
       greaterThan 0

注意column应该包含@{columnNane=imgr}，但它不包含任何内容。

用于解析的代码：

$objJson = Get-Content -Path $FileName -Raw | ConvertFrom-Json

有什么想法吗？

我拿了你的代码并且能够找到你正在寻找的对象我首先把它放在Here字符串@“”@并且能够到达它...然后就像你把它放在一个变量中管道转换为-json并得到了结果。

$test = @"
{
    "reportScope":  {
                        "agencyId":  "11111111111111111",
                        "advertiserId":  "22222222222222222"
                    },
    "reportType":  "adGroup",
    "columns":  [
                    {
                        "columnName":  "status"
                    },
                    {
                        "columnName":  "date"
                    },
                    {
                        "columnName":  "account"
                    },
                    {
                        "columnName":  "accountType"

                    {
                        "columnName":  "campaign"
                    },
                    {
                        "columnName":  "adGroup"
                    },
                    {
                        "columnName":  "deviceSegment"
                    },
                    {
                        "columnName":  "impr"
                    },
                    {

                    },
                    {
                        "columnName":  "dfaRevenue"
                    },
                    {
                        "columnName":  "cost"
                    },
                    {
                        "columnName":  "avgPos"
                    }
                ],
    "timeRange":  {
                      "startDate":  "2017-09-13",
                      "endDate":  "2017-08-14"
                  },
    "filters":  [
                    {
                        "column":  {"columnName":  "impr"},
                        "operator":  "greaterThan",
                        "values":  "0"
                    }
                ],
    "downloadFormat":  "csv",

"@
$t = $test | ConvertFrom-Json

$t.filters.column

PS C:\WINDOWS\system32> $t.filters

column             operator    values
------             --------    ------
@{columnName=impr} greaterThan 0     



PS C:\WINDOWS\system32> $t.filters.column

columnName
----------
impr

使用获取内容并使用convertfrom-json。

PS C:\WINDOWS\system32>     $test.filters

column             operator    values
------             --------    ------
@{columnName=impr} greaterThan 0     



PS C:\WINDOWS\system32>     $test.filters.column

columnName
----------
impr

可能是你的版本的convertFrom-json我的模块版本是：

PS C：\ WINDOWS \ system32＆gt; gcm convertfrom-json

CommandType名称版本来源
----------- ---- ------- ------
Cmdlet ConvertFrom-Json 3.1.0.0 Microsoft.PowerShell.Utility

Powershell ConvertFrom-Json吃节点
