Powershell - 从文本列表中获取服务器名称和IP

Question

我使用此链接中提供的以下建议: 专家交流

我正在尝试获取服务器(主机名)列表并将主机名和IP地址保存在.csv文件中.

使用以下Powershell代码,我会在结果窗格中看到每个服务器的主机名,但IP地址相同.

$servers = get-content "C:\TEMP\servers.txt"
$serversAndIps = "C:\TEMP\List_of_servers_with_ips.csv"


$results =@()
foreach ($server in $servers) {
  $results =@()
    $result = "" | Select ServerName , ipaddress
    $result.ipaddress = [System.Net.Dns]::GetHostAddresses($server)
  foreach($a in $addresses) {
    "{0},{1}" -f $server, $a.IPAddressToString
  }
    $result.servername = $server
    $results += $result
}
$results | export-csv -NoTypeInformation $serversandips

当我打开.csv文件时,我得到了这个:

"ServerName","ipaddress"
"Server_name_1","System.Net.IPAddress[]"

如果我运行此PowerShell脚本,我可以在结果窗格中获取主机名和正确的IP地址.我只需要知道如何将结果传输到.csv文件.

$servers = get-content "C:\TEMP\servers.txt"
foreach ($server in $servers) {
  $addresses = [System.Net.Dns]::GetHostAddresses($server)
  foreach($a in $addresses) {
    "{0},{1}" -f $server, $a.IPAddressToString
  }
}

有什么建议？

在工作中看起来像一些简单的错别字.

• $ result被重置在循环中
• 循环内的$地址未分配.
• $ result.ipaddress未分配给输出对象的$ a.IPAddressToString.

试试这个:

$servers = get-content "X:\servers.txt"
$serversAndIps ="X:\test.csv"

$results = @()
foreach ($server in $servers)
{
    $result = "" | Select ServerName , ipaddress
    $result.ipaddress = [System.Net.Dns]::GetHostAddresses($server)
    $addresses = [System.Net.Dns]::GetHostAddresses($server)

    foreach($a in $addresses) 
    {
        "{0},{1}" -f $server, $a.IPAddressToString
        $result.ipaddress = [System.Net.Dns]::GetHostAddresses($server)
    }

    $result.servername = $server
    $result.ipaddress = $a.IPAddressToString
    $results += $result
}

$results | export-csv -NoTypeInformation $serversandips
