如何使用 PowerShell 将文件附加到电子邮件

Question

我已经编写了一个 PowerShell 脚本来创建电子邮件，但我似乎无法附加文件。该文件确实存在并且 PowerShell 可以打开它，谁能告诉我我做错了什么？

$ol = New-Object -comObject Outlook.Application 
$message = $ol.CreateItem(0)
$message.Recipients.Add("Deployment")  
$message.Subject = "Website deployment"  
$message.Body = "See attached file for the updates made to the website`r`n`r`nWarm Regards`r`nLuke"

# Attach a file this doesn't work
$file = "K:\Deploy-log.csv"
$attachment = new-object System.Net.Mail.Attachment $file
$message.Attachments.Add($attachment)

Answer 1

如果您使用的是 PowerShell 2.0，只需使用内置 cmdlet Send-MailMessage：

C:\PS>Send-MailMessage -from "User01 <[email protected]>" `
                       -to "User02 <[email protected]>", `
                           "User03 <[email protected]>" `
                       -subject "Sending the Attachment" `
                       -body "Forgot to send the attachment. Sending now." `
                       -Attachment "data.csv" -smtpServer smtp.fabrikam.com

如果您复制/粘贴此内容，请注意反引号后添加的额外空格。 PowerShell 不喜欢它。

使上述工作正常工作

$attachment = new-object System.Net.Mail.Attachment $file

我通过删除该行并更改

$message.Attachments.Add($attachment)

为来

$message.Attachments.Add($file)

，虽然@Keith Hill 提供的解决方案会更好，但即使经过大量的护目镜，我也无法使其工作。

这对我使用 powershell-

定义变量有用：

$fromaddress = "[email protected]" 
$toaddress = "[email protected]" 
$Subject = "Test message" 
$body = "Please find attached - test"
$attachment = "C:\temp\test.csv" 
$smtpserver = "mail.pd.com" 

使用脚本中的变量：

$message = new-object System.Net.Mail.MailMessage 
$message.From = $fromaddress 
$message.To.Add($toaddress)
$message.IsBodyHtml = $True 
$message.Subject = $Subject 
$attach = new-object Net.Mail.Attachment($attachment) 
$message.Attachments.Add($attach) 
$message.body = $body 
$smtp = new-object Net.Mail.SmtpClient($smtpserver) 
$smtp.Send($message)

Answer 4

我遇到过这样的问题，（Windows 10 / PS 5.1）
我的 SMTP 未经过验证或安全...
我必须通过“MyAttacheObject.Dispose()”这一行来完成
.../终于可以工作了：！

$smtp = new-object Net.Mail.SmtpClient($smtpserver) 
$attach.Dispose()

这是我的代码，有两个附件：

# Email configuration NO AUTH NO SECURE
$emailHost = "smtp.bot.com"
$emailUser = ""
$emailPass = ""
$emailFrom = "[email protected]"
$emailsTo=@("[email protected]","[email protected]")
$emailSubject = $title
$emailbody=$body
$attachment1 = @($PATh+$outFile) 
$attachment2 = @($PATh+$inFile) 
#End of parameters

$msg = New-Object System.Net.Mail.MailMessage
$msg.from = ($emailFrom)
    foreach ($d in $emailsTo) {    
    $msg.to.add($d)
    }
$msg.Subject = $emailSubject
$msg.Body = $emailbody
$msg.isBodyhtml = $true   

$att = new-object System.Net.Mail.Attachment($attachment1)
$msg.Attachments.add($att)
$att = new-object System.Net.Mail.Attachment($attachment2)
$msg.Attachments.add($att)
$smtp = New-Object System.Net.Mail.SmtpClient $emailHost
$smtp.Credentials = New-Object System.Net.NetworkCredential($emailUser, $emailPass);
  $smtp.send($msg)
  $att.Dispose()

"yourpassword" | ConvertTo-SecureString -AsPlainText -Force | ConvertFrom-SecureString | Out-File "D:\Password.txt"

# The above command will encrypt the password you need to run this command only one time

# 1.Sign in to your work or school account, go to the My Account page, and select Security info.
2.Select Add method, choose App password from the list, and then select Add.
3.Enter a name for the app password, and then select Next. it will give password 
# you should use this password in above mentioned command

$User = "[email protected]"
$File = "C:\Users\username\Desktop\Mail\Password.txt"
$cred=New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $User, (Get-Content $File | ConvertTo-SecureString -AsPlainText -Force)
$EmailTo = "[email protected]"
$EmailFrom = "[email protected]"
$Subject = "SERVICE STOPPED"
$Body = "SERVICE STOPPED PFA Document to get more details."
$SMTPServer = "smtp.office365.com"
$filenameAndPath = "C:\Users\username\Desktop\new.txt"
$SMTPMessage = New-Object System.Net.Mail.MailMessage($EmailFrom,$EmailTo,$Subject,$Body)
$attachment = New-Object System.Net.Mail.Attachment($filenameAndPath)
$SMTPMessage.Attachments.Add($attachment)
$SMTPClient = New-Object Net.Mail.SmtpClient($SMTPServer, 587)
$SMTPClient.EnableSsl = $true
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($cred.UserName, $cred.Password);
$SMTPClient.Send($SMTPMessage)

Answer 6

我需要删除“-AsPlainText -Force”

$emailCred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $emailUser, (Get-Content $emailPasswordFile | ConvertTo-SecureString)

Answer 7

Send-MailMessge 已过时。

2024.06.13 我本来打算使用 Send-MailMessge 但看到 Microsoft 声明已过时。

Send-MailMessage cmdlet 已过时。此 cmdlet 不保证与 SMTP 服务器的安全连接。虽然 PowerShell 中没有立即可用的替代方案，但我们建议您不要使用 Send-MailMessage。

Answer 8

您可以使用 send-mailmessage 或 system.net.mail.MailMessage 来完成它。有趣的是，两种方法之间存在显着的执行时间差异。您可以使用measure-command来观察命令的执行时间。
