powershell-2.0 - 用于发送邮件消息的 Powershell 内联“if”

Question

是否可以在 PowerShell 中仅在要传递变量的情况下在 cmdlet 调用上添加参数？

例如

Send-MailMessage -To $recipients (if($copy -ne "") -cc $copy) ....

Answer 1

不是你上面写的方式，但你可以splat 参数，用条件构建散列，所以你只有一次调用send-mailmessage. 几个月前我写的一个脚本的例子：

#Set up default/standard/common parameters
$MailParams = @{
"Subject"="This is my subject";
"BodyAsHtml" = $true;
"From" = $MailFrom;
"To" = $MailTo;
"SmtpServer" = $SMTPServer;
};

#On the last day of the month, attach a logfile.
if ((Get-Date).AddDays(1).Day -eq 1) {
$attachment = $LogFilePath;
$ReportContent = "Full log for the the preceding month is attached.<br><br>" + $ReportContent;
$MailParams.Add("Attachments",$attachment);
}

send-mailmessage @MailParms

因此，在您的情况下，它将是：

$MailParams = @{
"Subject"="This is my subject";
"From" = $MailFrom;
"To" = $recipients;
"SmtpServer" = $SMTPServer;
};

if (($copy -ne [string]::empty) -and ($copy -ne $null)) {
$MailParms.Add("CC",$copy);
}

send-mailmessage @MailParms
