使用bat文件将文件发送到电子邮件地址而不暴露电子邮件信息？

如果您需要通过使用带有用于生成和发送电子邮件的逻辑的PowerShell脚本来发送电子邮件（甚至带有附件），则可以通过将敏感值作为参数传递的批处理脚本来执行它，而不是将敏感值硬编码到其中脚本逻辑。

在PowerShell脚本逻辑可以接受的参数，如Gmail的本地邮箱的用户名，密码进行身份验证以发送电子邮件，和其他任何你不想硬编码在脚本中。

• PowerShell Args

  在脚本或函数中，您可以使用$ args数组引用未命名的参数，例如，将所有参数传递给cmdlet。您还可以通过其位置引用特定的参数：

  “第一个参数是“ + $Args[0]”

  “第二个参数是“ + $Args[1]”

您还可以将逻辑放入批处理脚本中，以便它也具有参数，您可以在执行时将敏感值传递给它，并使用参数占位符而不是对敏感值进行硬编码。

• 批次精氨酸

  您可以%在命令行上使用后跟数字位置的形式获取任何参数的值。传递的第一个项目始终%1是第二个项目始终%2以此类推

  ％*批处理脚本是指所有的参数（如%1 %2 %3 %4 %5 ...%255）只有参数%1来%9可以通过编号来引用。

这样，如果打开了脚本，您需要保护的敏感值将不会暴露或硬编码到脚本逻辑中，任何人都可以看到谁对该脚本具有读取权限。

重要说明： 每个PowerShell脚本示例名称“批处理执行脚本”的底部都有一个部分，具有可从批处理脚本执行的逻辑或执行的逻辑，因此您将使用传递用户名，密码和/或附件完整路径作为批处理脚本的适当参数，即sendemail.bat "<GmailAccountName>" "<GmailPassword>" "<FullPathAttachment>"

PowerShell脚本（无附件）

$Username      = $args[0]
$EmailPassword = $args[1]

$Username = $Username
$EmailTo = "[email protected]" 
$EmailFrom = "[email protected]"
$Subject = "Email Subject"
$Body = "Email Body"
$SMTPServer = "smtp.gmail.com" 
$SMTPMessage = New-Object System.Net.Mail.MailMessage($EmailFrom, $EmailTo, $Subject, $Body)
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587) 
$SMTPClient.EnableSsl = $true 
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($Username, $EmailPassword); 
$SMTPClient.Send($SMTPMessage)

批处理执行脚本

SET GmailAccount=%~1
SET GmailPassword=%~2
SET PowerShellDir=C:\Windows\System32\WindowsPowerShell\v1.0
CD /D "%PowerShellDir%"
Powershell -ExecutionPolicy Bypass -Command "& 'C:\Scripts\SendEmail.ps1' '%GmailAccount%' '%GmailPassword%'"

PowerShell脚本（带有附件）

$Username      = $args[0]
$EmailPassword = $args[1]
$Attachment    = $args[2]

$Username = $Username
$EmailTo = "[email protected]" 
$EmailFrom = "[email protected]"
$Subject = "Email Subject"
$Body = "Email Body"
$SMTPServer = "smtp.gmail.com" 
$SMTPMessage = New-Object System.Net.Mail.MailMessage($EmailFrom, $EmailTo, $Subject, $Body)
$Attachment = New-Object System.Net.Mail.Attachment($Attachment)
$SMTPMessage.Attachments.Add($Attachment)
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587) 
$SMTPClient.EnableSsl = $true 
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($Username, $EmailPassword); 
$SMTPClient.Send($SMTPMessage)

批处理执行脚本

SET GmailAccount=%~1
SET GmailPassword=%~2
SET Attachment=%~3
SET PowerShellDir=C:\Windows\System32\WindowsPowerShell\v1.0

Powershell -ExecutionPolicy Bypass -Command "& 'C:\Scripts\SendEmail.ps1' '%GmailAccount%' '%GmailPassword%' '%Attachment%'"

批处理脚本（动态）

这是一个多合一的动态批处理脚本，您只需传递Gmail帐户用户名，Gmail帐户密码以及附件的完整路径即可。

@ECHO OFF

SET GmailAccount=%~1
SET GmailPassword=%~2
SET Attachment=%~3

CALL :PowerShell
CD /D "%PowerShellDir%"
Powershell -ExecutionPolicy Bypass -Command "& '%PSScript%' '%GmailAccount%' '%GmailPassword%' '%Attachment%'"
EXIT

SET PSScript=%temp%\~tmpSendeMail.ps1
IF EXIST "%PSScript%" DEL /Q /F "%PSScript%"

ECHO $Username      = $args[0]>> "%PSScript%"

您可以像这样执行批处理脚本。。。

 sendemail.bat "<GmailAccountName>" "<GmailPassword>" "<FullPathAttachment>"

批处理脚本（静态和自删除）

该脚本将在的变量设定的硬编码值GmailAccount=，GmailPassword=以及Attachment=但是一旦执行，将完全删除[本身]脚本通过"%~FN0"其中0的脚本本身。这意味着您将要确保复制此脚本，然后仅在不希望公开此信息的位置从要执行的计算机上运行该副本。

@ECHO OFF

SET GmailPassword=<GmailPassword>
SET Attachment=<FullAttachmentPath>

CALL :PowerShell
CD /D "%PowerShellDir%"

  此外，FOR变量引用的替换已得到增强。现在，您可以使用以下可选语法：

  %~I         - expands %I removing any surrounding quotes (")
  %~nI        - expands %I to a file name only
  %~fI        - expands %I to a fully qualified path name
