Thumbprint将Powershell检索证书作为字符串还是字符串变量

我正在尝试将一些PowerShell代码组合在一起,以遍历服务器列表,返回有关其IIS站点和绑定的一些信息,如果它们具有https绑定,请获取certificateHash并使用它通过指纹来查找证书并返回其到期日期。

我遇到的问题是,当我在$ binding.cerficateHash下运行我的代码时,似乎返回了我期望的字符串cert Hash,但是当我使用那个certificateHash属性尝试通过其获取证书时指纹,它不起作用...但是当我获取certificateHash值的原始字符串值并对其进行硬编码时,它就起作用了...

我已经检查了certificateHash.GetType(),它似乎只是一个字符串,所以我不明白我在做什么错,并且我尝试了一些尝试,但无济于事,因为这是我的第一次破解powershell,所以有很多我不知道。

$sites = Invoke-Command  -ComputerName $serverName { Import-Module WebAdministration; Get-ChildItem -path IIS:\Sites }  -ErrorAction SilentlyContinue 

foreach($site in $sites)
{
   $serverName
   $site.name
   $site.physicalPath

   foreach($binding in $site.bindings.Collection)
   {
        $binding.protocol 
        $binding.bindingInformation 
        $binding.certificateHash 
        $binding.certificateStoreName

        if($binding.certificateHash)
        {
            # This outputs AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA 
            $binding.certificateHash 

            # this retrieves a cert and returns its expiration date, Woohooo!
            Start-Job  Invoke-Command -ComputerName  $serverName -ScriptBlock  { (Get-ChildItem -path Cert:\LocalMachine\WebHosting | Where-Object {$_.Thumbprint -eq "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" })[0].GetExpirationDateString() }         

            # this does not find a cert, and ive tried many things, and no dice.
            Start-Job  Invoke-Command -ComputerName  $serverName -ScriptBlock  { (Get-ChildItem -path Cert:\LocalMachine\WebHosting | Where-Object {$_.Thumbprint -eq $binding.certificateHash })[0].GetExpirationDateString() }                        

            # i've tried extracting the hash via "tostring" and using that, no dice
            $hash = $binding.certificateHash.ToString() 
            Start-Job  Invoke-Command -ComputerName  $serverName -ScriptBlock  { (Get-ChildItem -path Cert:\LocalMachine\WebHosting | Where-Object {$_.Thumbprint -eq $hash })[0].GetExpirationDateString() }                       

            # i've tried adding some wildcards and using the -like operator, no dice.
            $hash = "*" + $binding.certificateHash + "*" 
            Start-Job  Invoke-Command -ComputerName  $serverName -ScriptBlock  { (Get-ChildItem -path Cert:\LocalMachine\WebHosting | Where-Object {$_.Thumbprint -lilke $hash })[0].GetExpirationDateString() }                                    
        }
   }      
}

网站的示例输出。

  • Site1
  • D:\ Apps \ site1
  • http
  • *:80:Site1-test.ourdomain.com
  • https
  • *:443:Site1-test.ourdomain.com
  • AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
  • 虚拟主机

您在其上调用脚本块的计算机不知道本地会话中的$binding变量。 (这也是为什么它在传递文字字符串时起作用的原因。)

尝试将值作为参数传递:

Invoke-Command -Computer $serverName -Script {
   param ($hash)
   (gci Cert:\LocalMachine\WebHosting | ? Thumbprint -eq $hash)[0].GetExpirationDateString()
} -Arg $binding.certificateHash
