首先,先谢谢你。我试图使用PowerShell从下面的JSON字符串中检索以下值,但是遇到了问题。

ScheduleTitle,
Title,
Environment and Title
Resolution,
Width,
Height

JSON:

代码:

Param( [string]$result, [string]$rootPath )
try{ 
    $json = $result
    $parsed = $json | ConvertFrom-Json
    $output= ''
    foreach ($line in $parsed | Get-Member) { 
        Write-Output $parsed.$($line.Resolution).property1 
        Write-Output $parsed.$($line.Resolution).property2 
        $output += $parsed.$($line.Resolution).property1 + " " + $parsed.$($line.Resolution).property1 
    }
}

使用$parsed数据,您可以提取所需的所有信息。

例如,提取宽度:

echo $parsed.AutomationRunItems.Resolution.Width

应打印:1280

我认为这些都是您需要提取的所有字段。请注意,由于您没有精确指定输出,我只使用了逗号分隔的字符串:

$output= ''
$output = $output + $parsed.ScheduleTitle + ','
$output = $output + $parsed.AutomationRunItems.Case.Title + ','
$output = $output + $parsed.AutomationRunItems.Environment.Title + ','
$output = $output + $parsed.AutomationRunItems.Resolution.Width + ','
$output = $output + $parsed.AutomationRunItems.Resolution.Height

应打印:Resolution Testing,Resolution Test,Se Chrome,1280,1024
