Question

我编写了自己的函数，以HTML格式向最终用户发送电子邮件。如果我在我的脚本中使用以下格式To: ，这对一个用户或多个用户都无瑕疵：

$MailTo = "<User1@domain.com>", "<User2@domain.com>"

但是，当我尝试在Windows中使用相同的参数启动计划任务时，PowerShell会抱怨Cannot find an object with identity User1@domain.com或邮件仅发送给一个用户，而不是两者都发送。

我按计划任务或提示启动脚本的方式，这不起作用：

powershell -File "S:\Script\Send_Mail.ps1" -MailTo "<User1@domain.com>", "<User2@domain.com>"

即使我尝试其中一个参数，也只发送一封邮件：

-MailTo "<User1@domain.com>, <User2@domain.com>"
-MailTo "User1@domain.com, User2@domain.com"

我找到了this，但我不明白我做错了什么。谢谢你的帮助。

脚本：

[CmdletBinding(SupportsShouldProcess=$True)]
Param (
      [parameter(Mandatory=$true,Position=0)]
      [String[]] $MailTo,
      [parameter(Mandatory=$true,Position=1)]
      [String[]] $Subject,
      [parameter(Mandatory=$true,Position=2)]
      [String[]] $Message1
    )

Function Send-Mail {

[CmdletBinding(SupportsShouldProcess=$True)]
Param (
      [parameter(Mandatory=$true,Position=0)]
      [String[]] $To,
      [parameter(Mandatory=$true,Position=1)]
      [String[]] $Subject,
      [parameter(Mandatory=$true,Position=2)]
      [String[]] $Message1,
      [parameter(Mandatory=$false,Position=3)]
      [String[]] $Message2
    )

# Set SMTP server name
$PSEmailServer = "SMTP.Server"

# Check where we've been launched from
if($PSISE) {
  $LaunchedFrom = "Windows PowerShell ISE"
}
else {
     $LaunchedFrom = "Scheduled task or console (not ISE)"
}

Send-Mail $MailTo $Subject $Message1

解决方案

更正参数以仅接受需要的数组（多个$MailTo）：

Param (
      [parameter(Mandatory=$true,Position=0)]
      [String[]] $MailTo,
      [parameter(Mandatory=$true,Position=1)]
      [String] $Subject,
      [parameter(Mandatory=$true,Position=2)]
      [String] $Message1
    )

要从Windows中的计划任务运行此功能，您可以使用以下格式：

powershell "S:\Script\Send_Mail.ps1" -ImportFile "S:\Script\Servers.csv" -MailTo "User1@domain.com", "User2@domain.com"
powershell -ExecutionPolicy Bypass "S:\Script\Send_Mail.ps1" -ImportFile "S:\Script\Servers.csv" -MailTo "User1@domain.com", "User2@domain.com"

这些格式不被接受，会导致语法错误，或者并非所有用户都收到他们的电子邮件：

powershell -File "S:\Script\Send_Mail.ps1" -ImportFile "S:\Script\Servers.csv" -MailTo "User1@domain.com, User2@domain.com"
powershell -File "S:\Script\Send_Mail.ps1" -ImportFile "S:\Script\Servers.csv" -MailTo '"User1@domain.com", "User2@domain.com"'
powershell "S:\Script\Send_Mail.ps1" -ExecutionPolicy Bypass -ImportFile "S:\Script\Servers.csv" -MailTo "User1@domain.com, User2@domain.com"

上面的所有行都可以粘贴在PowerShell ISE中进行测试，因此您可以查看错误，而不是依赖于计划任务来告诉您。我希望它可以帮助你们，因为它吓坏了我：P

Answer 1

尝试这样：

powershell -File "S:\Script\Send_Mail.ps1" -MailTo "'User1@domain.com', 'User2@domain.com'"

Answer 2

您可以像这样定义“To”变量：

$emailTo = @('Name <name1@domain.com>', 'Name2 <name2@domain.com>')

然后您可以在函数Send-MailMessage

中使用它

示例：

$servername = hostname
$smtpserver = 'localhost'
$emailTo = @('username1 <user1@dom.com>', 'username2<user2@dom.com>')
$emailFrom = 'SomeServer <user3@dom.com>'
Send-MailMessage -To $emailTo -Subject 'Low available memory' -Body 'Warning' -SmtpServer $smtpserver -From $emailFrom

PowerShell将Send-MailMessage发送给计划任务中的多个收件人
