Powershell使用参数调用函数根据调用哪个参数

Question

我只是跳入 PowerShell 并尝试编写一个脚本来执行我根据调用的参数创建的函数。

示例：send-notification -WhichNotifcation dosomething

示例 2：发送通知 -WhichNotification dosomethingelse

我现在只调用第一个函数，而不是第二个。我做错了什么？

param(
    [parameter(Mandatory = $true)]
    [ValidateSet("dosomething", "dosomethingelse")]
    [ValidateNotNull()]
    [string]$WhichNotification
)

#Variables
$mailTo = "user@something.com"
$mailFrom = "user@somethingelse.com"
$smtpServer = "x.x.x.x"
$mailSubject1 = "Do Something"
$MailSubject2 = "do something else"

function Send-dosomething
{

    Send-MailMessage -To $mailTo -From $mailFrom -SmtpServer $smtpServer -Subject $mailSubject1 -Body "message1"
}


function Send-dosomethingelse
{
    Send-MailMessage -To $mailTo -From $mailFrom -SmtpServer $smtpServer -Subject $MailSubject2 -Body "message2"
}


if ($WhichNotification = "dosomething") {

    Send-dosomething

}
elseif ($WhichNotification = "dosomethingelse") {

    Send-dosomethingelse

}
else {

    Write-Host "Invalid"

}

Answer 1

我也倾向于做的常见错误，你正在做的是：

if ($WhichNotification = "dosomething") 

这样做是将变量 $WhichNotification 设置为“dosomething” - 在 if 块中计算为 $true。

你想做的是这样的：

if ($WhichNotification -eq "dosomething")
