Question

此脚本收集有关本地计算机证书的信息，并显示证书过期的日期（以JSON格式）。

{ "{#CERTINFO}" : "@{Expires in (Days)=8074}" }

我需要的只是8074（天），并且无法弄清楚如何编辑这个脚本。

$cert_ = get-childitem cert:LocalMAchine -recurse |
where-object {$_.NotAfter -gt (get-date)} |
select @{Name="Expires in (Days)";Expression={($_.NotAfter).subtract([DateTime]::Now).days}} |
Sort "Expires in (Days)"

write-host "{"
write-host " `"data`":[`n"
$idx = 1
foreach ($cert_arr in $cert_ )
{
if ($idx -lt $cert_.Count)

{
$line= "{ `"{#CERTINFO}`" : `"" + $cert_arr + "`" },"  
write-host $line 
}
elseif ($idx -ge $cert_.Count)
{
$line= "{ `"{#CERTINFO}`" : `"" + $cert_arr + "`" }"
write-host $line 
}
$idx++;
}
write-host
write-host " ]"
write-host "}"

我会尝试：

＆＃13;

function Get-CertInfo
{

    $cert_ = get-childitem cert:LocalMAchine -recurse | where-object {$_.NotAfter -gt (get-date)} | select @{Name="Expires in (Days)";Expression={($_.NotAfter).subtract([DateTime]::Now).days}} | Sort "Expires in (Days)"

    $data = @()

    foreach($c in $cert_)
    {
        $entry = [PSObject]@{"#CERTINFO"="$c"}

        $data += $entry
    }

    $certInfor = [PSObject]@{"data"=$data}

    $certInfor | ConvertTo-Json
}

＆＃13;

这会产生：

{
"data":  [
             {
                 "#CERTINFO":  "@{Expires in (Days)=221}"
             },
             {
                 "#CERTINFO":  "@{Expires in (Days)=272}"
             }
         ]
}

希望有所帮助。
