powershell - 显示编码的电子邮件主题

Question

我正在使用发送邮件消息向我们的支持系统发送电子邮件。但是当它发送电子邮件时，它会像这个屏幕一样显示主题行!

=?us-ascii?Q?R899076:Aman:System Summary ?=

在主题中我使用了变量:

$vUserName = (Get-Item env:\username).Value
$vComputerName = (Get-Item env:\Computername).Value
$subject = "$vComputerName : $vUserName : System Summary"

然后

send-MailMessage  -SmtpServer Smtp-local -To $to -From $from -Subject $subject -Body $body  -BodyAsHtml -Priority High 

但是当我在 Outlook 中收到这封电子邮件时，它看起来很好吗？

---

实际上这是一个大约 150 行的脚本，并且电子邮件正文和 smtp 服务器已经在服务器中指定。是的，我尝试了 $subject = "$env:ComputerName : $env:UserName : System Summary" 变量，结果是一样的。

是的，我试过 - 编码选项，但它给出了一个错误

Send-MailMessage : Cannot bind parameter 'Encoding'. Cannot convert the "utf8" value of type "Syste m.String" to type "System.Text.Encoding". At D:\PowerShell\MyScripts\SystemInfo\SysInfo-V6-test[notfinal].ps1:151 char:84 + send-MailMessage -SmtpServer $smtp -To $to -From $from -Subject $subject -Encoding <<<< utf8 -B ody $body -Attachments "$filepath\$name.html" -BodyAsHtml -Priority High + CategoryInfo : InvalidArgument: (:) [Send-MailMessage], ParameterBindingException + FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Microsoft.PowerShell.Commands.SendMai lMessage

有什么线索吗？

您可以编写一个自定义函数来使用 .net 发送，而不是使用 Send-MailMessage cmdlet。它要笨重得多，但可以解决这个问题。

像这样:

Function SendEmail  ($emailFrom, $emailTo, $subject, $body, $attachment) {

# Create from/to addresses  
$from = New-Object System.Net.Mail.MailAddress $emailFrom
$to =   New-Object System.Net.Mail.MailAddress $emailTo

# Create Message  
$message = new-object System.Net.Mail.MailMessage $from, $to  
$message.Subject = $subject  
$message.Body = $body

$attachment = new-object System.Net.Mail.Attachment($attachment)
$message.Attachments.Add($attachment)


# Set SMTP Server and create SMTP Client  
$server = <your server> 
$client = new-object system.net.mail.smtpclient $server  

# Send the message  
"Sending an e-mail message to {0} by using SMTP host {1} port {2}." -f $to.ToString(), $client.Host, $client.Port  
try {  
   $client.Send($message)  
   "Message to: {1}, from: {0} has beens successfully sent" -f $from, $to  
}  
catch {  
  "Exception caught in CreateTestMessage: {0}" -f $Error.ToString()  
} 

}
