我正在尝试创建一个脚本，以便为多个服务器远程获取网站的证书到期日期。我有一个适用于单个服务器的脚本（需要登录到服务器并执行），我需要远程运行多个服务器。如何修改此脚本以远程执行多个服务器。请指教。
$servers = get-content D:\Certificate.txt
$DaysToExpiration = 60 #change this once it's working
$expirationDate = (Get-Date).AddDays($DaysToExpiration)
foreach ($server in $servers)
{
$sites = Get-Website | ? { $_.State -eq "Started" } | % { $_.Name }
$certs = Get-ChildItem IIS:SSLBindings | ? {
$sites -contains $_.Sites.Value
} | % { $_.Thumbprint }
Get-ChildItem CERT:LocalMachine/My | ? {
$certs -contains $_.Thumbprint -and $_.NotAfter -lt $expirationDate
}
}

受https://iamoffthebus.wordpress.com/2014/02/04/powershell-to-get-remote-websites-ssl-certificate-expiration/的启发我使用以下脚本：
$minimumCertAgeDays = 60
$timeoutMilliseconds = 10000
$urls = get-content .\check-urls.txt
#disabling the cert validation check. This is what makes this whole thing work with invalid certs...
[Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}
foreach ($url in $urls)
{
Write-Host Checking $url -f Green
$req = [Net.HttpWebRequest]::Create($url)
$req.Timeout = $timeoutMilliseconds
$req.AllowAutoRedirect = $false
try {$req.GetResponse() |Out-Null} catch {Write-Host Exception while checking URL $url`: $_ -f Red}
$certExpiresOnString = $req.ServicePoint.Certificate.GetExpirationDateString()
#Write-Host "Certificate expires on (string): $certExpiresOnString"
[datetime]$expiration = [System.DateTime]::Parse($req.ServicePoint.Certificate.GetExpirationDateString())
#Write-Host "Certificate expires on (datetime): $expiration"
[int]$certExpiresIn = ($expiration - $(get-date)).Days
$certName = $req.ServicePoint.Certificate.GetName()
$certPublicKeyString = $req.ServicePoint.Certificate.GetPublicKeyString()
$certSerialNumber = $req.ServicePoint.Certificate.GetSerialNumberString()
$certThumbprint = $req.ServicePoint.Certificate.GetCertHashString()
$certEffectiveDate = $req.ServicePoint.Certificate.GetEffectiveDateString()
$certIssuer = $req.ServicePoint.Certificate.GetIssuerName()
if ($certExpiresIn -gt $minimumCertAgeDays)
{
Write-Host Cert for site $url expires in $certExpiresIn days [on $expiration] -f Green
}
else
{
Write-Host WARNING: Cert for site $url expires in $certExpiresIn days [on $expiration] -f Red
Write-Host Threshold is $minimumCertAgeDays days. Check details:`nCert name: $certName -f Red
Write-Host Cert public key: $certPublicKeyString -f Red
Write-Host Cert serial number: $certSerialNumber`nCert thumbprint: $certThumbprint`nCert effective date: $certEffectiveDate`nCert issuer: $certIssuer -f Red
}
Write-Host
rv req
rv expiration
rv certExpiresIn
}
或者，您可能会发现此高级脚本很有用：
这里是高级脚本代码：

[string]$ReportType = 'Text',

[string]$UrlsFile = '.\check-urls.txt',
[parameter(Mandatory=$false,ParameterSetName = "List of URLs",
ValueFromPipeline=$true,ValueFromPipelineByPropertyName=$true)]
[string[]]$Urls
)
Begin
{
[string[]]$allUrls = @()
$returnData = @()
[bool]$ProcessedInputPipeLineByArrayItem = $false
function CheckUrl ([string]$url, [array]$returnData)

if ($ReportType -eq "Html")
{

Write-Host "<tr><td>$stringHtmlEncoded</td>"
}
if ($ReportType -eq "Text") { Write-Host Checking $url }
$req = [Net.HttpWebRequest]::Create($url)

try
{
$req.GetResponse() |Out-Null
if ($req.ServicePoint.Certificate -eq $null) {$details = "No certificate in use for connection"}
}
catch
{
$details = "Exception while checking URL $url`: $_ "
}
if ($details -eq $null -or $details -eq "")
{
$certExpiresOnString = $req.ServicePoint.Certificate.GetExpirationDateString()
#Write-Host "Certificate expires on (string): $certExpiresOnString"
[datetime]$expiration = [System.DateTime]::Parse($req.ServicePoint.Certificate.GetExpirationDateString())

if ($certExpiresIn -gt $minimumCertAgeDays)
{
if ($ReportType -eq "Html")
{
Write-Host "<td>OKAY</td><td>$certExpiresIn</td><td>$expiration</td><td> </td></tr>"
}
if ($ReportType -eq "Text")
{
Write-Host OKAY: Cert for site $url expires in $certExpiresIn days [on $expiration] -f Green

if ($ReportType -eq "PSObject")
{
$returnData += new-object psobject -property @{Url = $url; CheckResult = "OKAY"; CertExpiresInDays = [int]$certExpiresIn; ExpirationOn = [datetime]$expiration; Details = [string]$null}

}
else

}
}
else
{
if ($ReportType -eq "Html")
{

}
#disabling the cert validation check. This is what makes this whole thing work with invalid certs...
[Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}
if ($ReportType -eq "Html")
{
Write-Host "<table><tr><th>URL</th><th>Check result</th><th>Expires in days</th><th>Expires on</th><th>Details</th></tr>"

Process

End
{

{
if ($Urls -eq $null)
{

{
$returnData = CheckUrl $url $returnData
}
}
if ($ReportType -eq "Html") { Write-Host "</table>" }
if ($ReportType -eq "PSObject") { return $returnData }
}
输出可能看起来像例如：
"http://www.doma.com", "https://www.domb.com" | .\Check-ExpiringSslCerts.ps1 -ReportType PSObject | ft

--- ------------ ----------------- ----------- -------

将你在脚本块中编写的整个代码放入，为了做到这一点，只需在开头添加此代码：
$sb = {
并在代码底部添加：
}
拥有此脚本块后，您可以使用以下命令在服务器上远程运行此脚本：
$cred = Get-Credential
$servers = get-content D:\Certificate.txt
Invoke-Command -Credential $cred -ComputerName $servers -ScriptBlock $SB
希望它有所帮助！

您的代码段很有帮助，但是它们会在HTTP错误时引发错误-这是基础.NET HttpWebRequest对象的本质，它会惊慌于所有非代码200的内容。
因此，例如，如果您要测试仅接受POST HTTP动词的API端点，则脚本将失败，因为它将收到405错误消息。或者，如果您的URL返回HTTP 404，则脚本也会失败。幸运的是，无论如何，您都可以捕获第7层错误并捕获所需的信息，只需以这种方式修补代码即可：
try {$req.GetResponse() | Out-Null } catch {
if ($_.Exception.InnerException.Status -eq 'ProtocolError') {
# saving the info anyway since this is a L7 error, e.g.:
$certExpiresOnString = $req.ServicePoint.Certificate.GetExpirationDateString()
[datetime]$expiration [System.DateTime]::Parse($req.ServicePoint.Certificate.GetExpirationDateString())
$certIssuer = $req.ServicePoint.Certificate.GetIssuerName() # ...
} else {
# this is a real error - timeout, DNS failure etc
Write-Host "$url, $_" -ForegroundColor Red
Continue
}
}

主要取自https://gist.github.com/jstangroome/5945820，尽管有所变化。以下将获得证书。然后需要检查$certificate.NotBefore和$certificate.NotAfter。
function GetCertificate([string]$domain, [Int16]$port) {
$certificate = $null
$TcpClient = New-Object -TypeName System.Net.Sockets.TcpClient
$TcpClient.ReceiveTimeout = 1000
$TcpClient.SendTimeout = 1000
try {
$TcpClient.Connect($domain, $port)
$TcpStream = $TcpClient.GetStream()
$Callback = { param($sender, $cert, $chain, $errors) return $true }
$SslStream = New-Object -TypeName System.Net.Security.SslStream -ArgumentList @($TcpStream, $true, $Callback)
try {
$SslStream.AuthenticateAsClient($domain)
$certificate = $SslStream.RemoteCertificate
}
finally {
$SslStream.Dispose()
}
}
finally {
$TcpClient.Dispose()
}
if ($certificate) {
if ($certificate -isnot [System.Security.Cryptography.X509Certificates.X509Certificate2]) {
$certificate = New-Object -TypeName System.Security.Cryptography.X509Certificates.X509Certificate2 -ArgumentList $certificate
}
}
return $certificate
}
