Pass Subject and Body parameter to a powershell Email script using batch file

Question

I have a powershell script ,

[System.Net.ServicePointManager]::SecurityProtocol = 'TLS12'
$Mail_to="[email protected]"
$Mail_from="[email protected]"
$Subject = "Test"
$Body = "Test Body"
$SMTPServer = "smtp.sendgrid.com"

Send-MailMessage -SmtpServer $SMTPServer -Port 587 -UseSsl -From $Mail_from -To $Mail_to -Subject $Subject -BodyAsHtml $body -Encoding ([System.Text.Encoding]::UTF8)

Now i want the $subject and $Body value to be obtained from a batch file and run the powershell script using that batch file, How to do it?

You need to add some parameters (e.g. -Subject and -Body) to your script, then call it like this: MyScript.ps1 -Subject "some text" -Body "more text". More info here: about_Functions — boxdog

What do you mean, "subject and body obtained from a batch file"? It's not clear what you're trying to accomplish. — Bacon Bits

Add to the start of the script a Param Section, you can use default value for the required parameters, save the file.

Param(
$Subject = "Test",
$Body = "Test Body"
)

[System.Net.ServicePointManager]::SecurityProtocol = 'TLS12'
$Mail_to="[email protected]"
$Mail_from="[email protected]"
$SMTPServer = "smtp.sendgrid.com"

Send-MailMessage -SmtpServer $SMTPServer -Port 587 -UseSsl -From $Mail_from -To $Mail_to -Subject $Subject -BodyAsHtml $body -Encoding ([System.Text.Encoding]::UTF8)

Call the PS1 file from the batch file using the required paramters, e.g:

powershell script.ps1 MySubject MyBody
