keys（并且数组中有更多记录......）

我怎样才能搜索记录kid = "SsZsBNhZcF3Q9S4trpQBTByNRRI"然后返回它的x5c属性？

以下是查找记录的好方法（我很困惑-expand，它是否会剥离外部 JSON 对象并仅返回keys数组？）然后如何访问它的x5c属性？

将函数的输出存储在变量中，例如：

$var = Invoke-WebRequest https://login.microsoftonline.com/common/discovery/v2.0/keys | ConvertFrom-Json

然后取变量的“keys”和“x5c”部分：

$var.keys; $var.x5c

这是日常的PowerShell。管它。看起来 x5c 也是一个数组。

| select -expand x5c
