本文介绍了遍历JSON数组并打印出相同的键值的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

具有多个具有相同键的JSON数组，该键显示时代，要打印然后输出并将其转换为EST

Have JSON array with multiple keys of same which shows time in epoch, want to print then out and convert time to EST

{
"contents":[
      {
        "name":"windows-Instance",
        "Buildid":"1234",
        "Buildtime":"1563350400238"
      },
      {
        "name":"linux-Instance",
        "Buildid":"1454",
        "Buildtime":"1563264000198"
      },
      {
      "name":"linux-Instance",
        "Buildid":"1278685",
        "Buildtime":"1563177600092"
       }
  ]
}

推荐答案

您可以尝试将每个将Epoch转换为当前时区的对象打印出来：

You can try this out to print each objects converted Epoch to current timezone:

Function Get-EpochDate ($epochDate) { [timezone]::CurrentTimeZone.ToLocalTime(([datetime]'1/1/1970').AddMilliseconds($epochDate)) }

$contents = (Get-Content .\test.json | ConvertFrom-Json).contents

foreach ($object in $contents) {
    $seconds = [long]$object.Buildtime
    Write-Output (Get-EpochDate $seconds)
}

输出：
