如果您只需要绑定到443的站点，则只需添加该条件。

Foreach ($Site in get-website) { Foreach ($Bind in $Site.bindings.collection | where bindinginformation -like '*443*') {[pscustomobject]@{Bindings=$Bind.bindinginformation.Split(":")[-1]}}}

我还建议您将命令拆分，以便更易于阅读和维护。

$sitelist = Get-Website

Foreach ($site in $sitelist) {
    $bindinglist = $site.bindings.collection | where bindinginformation -like '*443*'

    Foreach ($bind in $bindinglist) {
        [pscustomobject]@{
            Bindings = $bind.bindinginformation.Split(":")[-1]
        }
    }
}

我将从以下代码片段开始：

#Requires -RunAsAdministrator
Import-Module Webadministration
Foreach ($Site in get-website) {
    Foreach ($Bind in $Site.bindings.collection) {
        [pscustomobject]@{
            SiteName = $Site.Name
            Bindings = $Bind.bindinginformation
        }
    }
}

然后，缩小输出以获得443绑定，如下所示：

Foreach ($Site in get-website) {
    Foreach ($Bind in $Site.bindings.collection) {
        if ($Bind.bindinginformation -match ':443') {
            [pscustomobject]@{
                SiteName = $Site.Name
                Bindings = $Bind.bindinginformation
            }
        }
    }
}

输出 * 可能 * 如下所示：

SiteName          Bindings
--------          --------
site1.awesome.com *:443:
site2.awesome.com *:443:
