标签： powershell vbscript diskspace

我有一个脚本，我从MS论坛的某处获得 这个脚本工作得很好。我根据需要获得了电子邮件和html文件 但由于在多域环境中我需要提供不同的凭据 到不同的服务器。而不是使用相同的列表中的每个服务器的for循环 凭据，它应该使用其凭据处理每个服务器，但在同一个文件和电子邮件中 任何想法如何得到这个...... 提前致谢

$freeSpaceFileName = "c:\script\FreeSpace.htm"
$serverlist = "c:\script\computers.txt"

虽然您提供的代码中包含大量HTML格式，但我将与您分享一个更简单的示例，说明如何实现您的目标。

  1. 将您的computers.txt转换为CSV文件，其中包含两列，通过某个友好名称引用凭据对象（例如cred1或cred2）
  2. 在PowerShell中创建HashTable个不同的凭据，并使用您在CSV文件中使用的友好名称
  3. 对于CSV文件中的每台计算机，请使用其名称和凭据连接到WMI

    4. Computers.csv 

    Name,Credential
dc01,cred1
dc02,cred1
dc03,cred1
exch01,cred2
exch02,cred2
exch03,cred2
client01,cred3
client02,cred3
client03,cred3

    PowerShell脚本

    # Build a list of key/value pairs, to uniquely reference each of several credentials
$CredentialList = @{
    Cred1 = New-Object -TypeName pscredential -ArgumentList 'domain\user123', (ConvertTo-SecureString -String 'Password123' -AsPlainText -Force);
    Cred2 = New-Object -TypeName pscredential -ArgumentList 'domain\user456', (ConvertTo-SecureString -String 'Password456' -AsPlainText -Force);
    Cred3 = New-Object -TypeName pscredential -ArgumentList 'domain\user789', (ConvertTo-SecureString -String 'Password789' -AsPlainText -Force);
    }

# Get a list of computer/credential pairs
$ComputerList = Import-Csv -Path $PSScriptRoot\Computers.csv;

# For each computer in the CSV file, use the appropriate credential to contact WMI
foreach ($Computer in $ComputerList) {
    Get-WmiObject -ComputerName $Computer.Name -Class Win32_LogicalDisk -Credential $CredentialList[$Computer.Credential];
}
