我从 Ansible 任务之一得到如下字典输出“

msg": {
        "vSwitch0": {
            "failback": true,
            "failover_active": [
                "vmnic1",
                "vmnic0"
            ],
            "failover_standby": [],
            "failure_detection": "link_status_only",
            "lb": "loadbalance_srcid",
            "mtu": 1500,
            "notify": true,
            "num_ports": 128,
            "pnics": [
                "vmnic0",
                "vmnic1"
            ],
            "security": [
                false,
                false,
                false
            ],
            "ts": false
        }
    }
}

我正在尝试通过将上述输出存储在变量中作为“all_vswitch_info”并尝试提取 pnics 列表来使用 Json 查询，如下所示，当我现在使用下面的内容时，

• 调试：味精：“{{all_vswitch_info| json_query（'pnics'）}}”

我得到的是空值

ok: [localhost] => {
    "msg": ""
}

注意：我尝试使用其他选项作为 msg: "{{all_vswitch_info| json_query('[].pnics')}}" 但我仍然得到相同的结果

ok: [localhost] => {
    "msg": ""
}

有什么遗漏吗？注意：此特定输出具有 vSwitch0。在某些情况下，这可能是 vswitch23 或 vswitch 3 之类的任何名称或其他名称。我不能在 json_query 中将名称硬编码为 vSwitch0。但是，pnics是不会因目标机器而改变的属性名称。

我正在使用 PowerShell 的 MDT 任务序列，它使用这样的脚本

%SCRIPTROOT%\ConfigureWinRMwithCertificate_https.ps1

该脚本使用 https 完美地配置了 winrm，但每次，此任务都会在日志中创建异常消息，而不是我在脚本中编写的输出。

错误消息总是说脚本无法从网络驱动器执行（以下错误中隐藏的 IP 地址详细信息）：

有没有其他方法可以克服这个错误？

实际的 powershell 脚本代码是：

Function CheckWinRMHTTPSConfiguration{
[CmdletBinding()]
param(
[Parameter(Mandatory=$False)][System.Boolean]$isWinrmHttpsConfigured = $false
)

$state_of_WinrmHttps = Get-childItem -Path WSMan:\localhost\Listener | Select-Object -ExpandProperty Keys | where {$_ -match 'https'}
if($state_of_WinrmHttps){ $isWinrmHttpsConfigured = $true}
else { $isWinrmHttpsConfigured = $false}
return $isWinrmHttpsConfigured
}

Function ConfigureWinRMwithPROJECTAACertificate_https{

$Cert_output = Get-ChildItem Cert:\LocalMachine\My | Select @{N="Template";Expression={($_.Extensions |where-object {$_.oid.Friendlyname -match "Certificate Template Information"}).Format(0) -replace "(.+)?=(.+)\((.+)?", '$2'}},@{N="Subject";Expression={$_.SubjectName.name}},Thumbprint

$Thumbprint_of_PROJECTAA_Certificate = $($Cert_output.Thumbprint)

$FQDN_of_LocalMachine = ([System.Net.Dns]::GetHostByName($env:computerName).Hostname)

if(-not $Cert_output){
Write-Host "No certificate avaialable in $FQDN_of_LocalMachine"
}
elseif($Cert_output -is [System.Array]){
Write-Host "Multiple certificates are available in $FQDN_of_LocalMachine.Skipping…”
}
elseif ($Cert_output -isnot [System.Array] -and $($Cert_output.Template) -eq "ORGANIZATIONTEMPLATENAMEHERE"){
$command_construct = 'winrm create winrm/config/Listener?Address=*+Transport=HTTPS '+''''+ '@{Hostname=' +'"'+$FQDN_of_LocalMachine+'"'+';'+' CertificateThumbprint='+'"'+$Thumbprint_of_PROJECTAA_Certificate+'"'+'}'+''''
Invoke-expression -Command $command_construct
}
else{
Write-Host "nothing done"
}
}

Function ConfigureWINRM {
$state_of_WinRM_https = CheckWinRMHTTPSConfiguration
if($state_of_WinRM_https -eq $true){
Write-Host "Deleteing existing winrm https"
Invoke-Expression -Command 'winrm delete winrm/config/listener?Address=*+Transport=HTTPS';
ConfigureWinRMwithPROJECTAACertificate_https
}
else
{
Write-Host "configuring https listener for winrm"
ConfigureWinRMwithPROJECTAACertificate_https
}
}
Function Update_grouppolicy{
invoke-expression -Command 'gpupdate /force /wait:-1 /target:computer' -OutVariable gpupdate_output
Start-Sleep -Seconds 300
}
$output_Update_grouppolicy = Update_grouppolicy
if ($output_Update_grouppolicy -match "Computer Policy update has completed successfully"){

我有 2 个 sata 硬盘驱动器。我已经在一个上安装了 windows 10 操作系统，在另一个上安装了 red hat enterprise Linux 7，并使它们都可以启动。但总是，当我启动时，它直接进入windows 10。bios中的启动顺序配置为先加载windows安装的硬盘，然后再加载Linux安装的硬盘。我需要在帖子屏幕上看到双启动，以便我可以选择登录哪一个。

注意：我有 uefi bios 并在 uefi 中安装了两个操作系统作为旧版 bios。
